Movement Disorders: Key Features

Movement disorders refer to a range of conditions that affect voluntary muscle movements. These disorders can be caused by various factors, including neurological conditions, medication side effects, and metabolic imbalances. The following table outlines some of the key features of common movement disorders:

Akinesia: Absence of loss of control of voluntary muscle movements, often seen in severe Parkinson’s disease.

Bradykinesia: Slowness of voluntary movement, a core symptom of Parkinson’s disease.

Akathisia: Subjective feeling of inner restlessness, often caused by antipsychotic medication use.

Athetosis: Continuous stream of slow, flowing, writhing involuntary movements, often seen in cerebral palsy, stroke, and Huntington’s disease.

Chorea: Brief, quasi-purposeful, irregular contractions that appear to flow from one muscle to the next, often seen in Huntington’s disease and Wilson’s disease.

Dystonia: Involuntary sustained of intermittent muscle contractions that cause twisting and repetitive movements, abnormal postures, of both.

Dyskinesia: General term referring to problems with voluntary movements and the presence of involuntary movements, often drug-induced.

Myoclonus: A sequence of repeated, often non-rhythmic, brief shock-like jerks due to sudden involuntary contraction of relaxation of one of more muscles.

Parkinsonism: Syndrome characterized by tremor, rigidity, and bradykinesia.

Tic: Sudden, repetitive, non-rhythmic, stereotyped motor movement of vocalization involving discrete muscle groups, often seen in Tourette’s syndrome.

Tremor: Involuntary, rhythmic, alternating movement of one of more body parts, often seen in essential tremor, Parkinson’s disease, and alcohol withdrawal.

Hemiballismus: Repetitive, but constantly varying, large amplitude involuntary movements of the proximal parts of the limbs, often seen in stroke and traumatic brain injury.

Stereotypies: Repetitive, simple movements that can be voluntarily suppressed, often seen in autism and intellectual disability.

It is important to consider the underlying conditions and factors that may contribute to movement disorders in order to properly diagnose and treat these conditions.

SUDEP, of sudden unexpected death in epilepsy, is a condition where patients with epilepsy die suddenly and unexpectedly without any apparent cause. It is estimated to be responsible for 20-30% of deaths in epilepsy patients. The condition is more common in adults than in children, affecting 1 in 1,000 adults with epilepsy per year. The main risk factor for SUDEP is having active generalised tonic clonic seizures (GTCS), and better control of these seizures through improved compliance can reduce the risk of SUDEP. Other risk factors include nocturnal seizures, lamotrigine, never having been treated with an antiepileptic drug, intellectual disability, and male sex. However, the evidence for these factors is considered low. Autopsy findings in SUDEP cases do not reveal any specific cause of death, but obstruction of the airways and cardiorespiratory events such as arrhythmia are thought to be possible mechanisms.

Inhibited Mania

Inhibited mania is one of the six mixed affective states identified by Kraepelin. It is characterized by symptoms of both mania and depression, but with a predominance of depressive features. Patients with inhibited mania may experience feelings of sadness, guilt, and worthlessness, as well as decreased energy and motivation. At the same time, they may also exhibit symptoms of mania, such as increased activity, impulsivity, and irritability.

Inhibited mania is considered an autonomous mixed episode, meaning that the patient consistently experiences symptoms of both mania and depression. This type of mixed state is associated with a poorer prognosis compared to those occurring between transitions from one mood state to another.

Treatment for inhibited mania typically involves a combination of mood stabilizers, antidepressants, and psychotherapy. It is important for clinicians to carefully monitor patients with inhibited mania, as they may be at increased risk for suicide and other adverse outcomes.

Frontal Lobe Tests

The frontal lobe is responsible for a variety of cognitive functions, including initiation, abstraction, problem-solving, decision-making, response inhibition, and set shifting. Different tests can be used to assess these functions.

Verbal and categorical fluency tests can be used to assess initiation. These tests require individuals to generate as many words of items as possible within a specific category of starting letter.

Proverbs, similarities, and cognitive estimates are examples of tests that can be used to assess abstraction. These tests require individuals to identify similarities between objects of concepts, make judgments based on incomplete information, of estimate quantities.

Tower of London, Cambridge stockings, and gambling tasks are examples of tests that can be used to assess problem-solving and decision-making. These tests require individuals to plan and execute a sequence of actions to achieve a goal of make decisions based on uncertain outcomes.

Alternating sequences, go-no-go test, Luria motor test, trail making test, Wisconsin card sorting test, and Stroop test are examples of tests that can be used to assess response inhibition and set shifting. These tests require individuals to inhibit prepotent responses, switch between tasks of mental sets, of ignore irrelevant information.

Overall, these tests can provide valuable information about an individual’s frontal lobe functioning and can be used to diagnose and treat various neurological and psychiatric conditions.

Formal Thought Disorders

In formal thought disorders, changes in the speed, coherence, and cogency of thought can be observed from a patient’s speech. These disorders can also be self-reported and may be accompanied by enhanced use of nonverbal language. One possible indication is a lack of an adequate connection between two consecutive thoughts, which is called ‘asyndesis’.

There are several types of formal thought disorders, including inhibited thinking, retarded thinking, circumstantial thinking, restricted thinking, perseverative thinking, rumination, pressured thinking, flight of ideas, tangential thinking, thought blocking, disruption of thought, incoherence/derailment, and neologisms.

Inhibited thinking is about the subjective experience of the patient, who may feel that their thinking process is slowed down of blocked by an inner wall of resistance. Retarded thinking, on the other hand, is about the observed quality of thought as inferred through speech, where the flow of thought processes is slowed down and sluggish.

Circumstantial thinking refers to an inability to separate the essential from the unessential during a conversation without rendering the conversation incoherent. Restricted thinking involves a limited range of thought content, fixation on one particular topic of a small number of topics only, and a stereotyped pattern of thinking.

Perseverative thinking is characterized by the persistent repetition of previously used words, phrases, of details to the point where they become meaningless in the context of the current stage of the interview. Rumination is the endless mental preoccupation with, of excessive concern over, mostly unpleasant thoughts.

Pressured thinking, also known as crowding of thought, is when the patient feels helplessly exposed to the pressures of floods of different ideas of thoughts. Flight of ideas involves an increasing multitude of thoughts and ideas which are no longer firmly guided by clear goal-directed thinking.

Tangential thinking occurs when the patient appears to understand the contents of the questions addressed to them but provides answers which are completely out of context. Thought blocking of disruption of thought refers to sudden disruption of an otherwise normal flow of thought of speech for no obvious reason.

Incoherence of derailment is when the interviewer is unable to establish sensible connections between the patient’s thinking and verbal output, which is sometimes also called derailment. Neologisms involve the formation of new words of usage of words which disregard normal conventions and are generally not easily understandable.

While digit span is primarily used to assess working memory, it also involves executive attention, which is a component shared by tests of working memory capacity and executive function. Therefore, digit span cannot be considered solely a test of working memory.

The mental state exam assesses various areas of cognition, including orientation, attention/concentration, short term memory, long term memory, and executive function. Standard tests for each area include asking about time, place, and person for orientation, serial 7’s for attention/concentration, digit span for short term memory, delayed recall of name and address for long term memory, and various tasks such as proverbs, similarities, differences, verbal fluency, and cognitive estimates for executive function.

The DSM-5 employs the label ‘borderline personality disorder’, while the previous ICD utilized the term ’emotionally unstable personality disorder’, which was not included in the ICD-11. The ICD-11 now allows for the use of a borderline qualifier when providing a broad diagnosis of personality disorder.

Personality Disorder Classification

A personality disorder is a persistent pattern of behavior and inner experience that deviates significantly from cultural expectations, is inflexible and pervasive, and causes distress of impairment. The DSM-5 and ICD-11 have different approaches to classifying personality disorders. DSM-5 divides them into 10 categories, grouped into clusters A, B, and C, while ICD-11 has a general category with six trait domains that can be added. To diagnose a personality disorder, the general diagnostic threshold must be met before determining the subtype(s) present. The criteria for diagnosis include inflexibility and pervasiveness of the pattern, onset in adolescence of early adulthood, stability over time, and significant distress of impairment. The disturbance must not be better explained by another mental disorder, substance misuse, of medical condition.

Course

Borderline and antisocial personality disorders tend to become less evident of remit with age, while others, particularly obsessive-compulsive and schizotypal, may persist.

Classification

The DSM-5 divides personality disorders into separate clusters A, B, and C, with additional groups for medical conditions and unspecified disorders. The ICD-11 dropped the separate categories and instead lists six trait domains that can be added to the general diagnosis.

UK Epidemiology

The prevalence of personality disorders in Great Britain, according to the British National Survey of Psychiatric Morbidity, is 4.4%, with cluster C being the most common at 2.6%, followed by cluster A at 1.6% and cluster B at 1.2%. The most prevalent specific personality disorder is obsessive-compulsive (anankastic) at 1.9%.

La belle indifference is a term of French origin that refers to a paradoxical lack of emotional distress in individuals who have a serious medical illness of symptoms related to a health condition. This phenomenon is often observed in cases of conversion (dissociative) disorder.

Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterised by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behaviour. Somatoform disorders are characterised by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterised by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. The former involves bodily symptoms that the individual finds distressing and to which excessive attention is directed, while the latter involves a disturbance in the person’s experience of the body manifested by the persistent desire to have a specific physical disability accompanied by persistent discomfort of intense feelings of inappropriateness concerning current non-disabled body configuration. Dissociative disorders, on the other hand, are characterised by involuntary disruption of discontinuity in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behaviour. The ICD-11 dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. Each disorder has its own set of essential features and diagnostic criteria.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

Attitude scales are used to measure a person’s feelings and thoughts towards something. There are several types of attitude scales, including the Thurstone scale, Likert scale, semantic differential scale, and Gutman scale. The Thurstone scale involves creating a list of statements and having judges score them based on their negativity of positivity towards an issue. Respondents then indicate whether they agree of disagree with each statement. The Likert scale asks respondents to indicate their degree of agreement of disagreement with a series of statements using a five-point scale. The semantic differential scale presents pairs of opposite adjectives and asks respondents to rate their position on a five- of seven-point scale. The Gutman scale involves a list of statements that can be ordered hierarchically, with each statement having a corresponding weight. Respondents’ scores on the scale indicate the number of statements they agree with.

Assessing Executive Function with the Hayling and Brixton Tests

The Hayling and Brixton tests are two assessments designed to evaluate executive function. The Hayling Sentence Completion Test consists of two sets of 15 sentences, with the last word missing. In the first section, participants complete the sentences, providing a measure of response initiation speed. The second part, the Hayling, requires participants to complete a sentence with a nonsense ending word, suppressing a sensible one. This provides measures of response suppression ability and thinking time. Performance on such tests has been linked to frontal lobe dysfunction and dysexecutive symptoms in everyday life.

The Brixton Test is a rule detection and rule following task. Impairments on such tasks are commonly demonstrated in individuals with dysexecutive problems. Overall, these tests provide valuable insights into executive function and can help identify areas of weakness that may require intervention.

A limitation of the ACE-III is that it does not have a dedicated assessment for evaluating reasoning and decision-making abilities.

The Addenbrooke’s Cognitive Exam: A Brief Screening Tool for Dementia

The Addenbrooke’s cognitive examination (ACE) is a cognitive screening tool developed to detect dementia and differentiate Alzheimer’s dementia from frontotemporal dementia. It was created to address the limitations of the MMSE, which lacked sensitivity for frontal-executive dysfunction and visuospatial defects. The ACE is a brief test that takes 15-20 minutes to administer and is divided into five domains: attention and orientation, memory, verbal fluency, language, and visuospatial abilities. The total score is based on a maximum score of 100, with higher scores indicating better cognitive functioning.

The ACE has been shown to be a valid tool for detecting dementia, with two cut-off points often used depending on the required sensitivity and specificity. A score of less than 88 has 100% sensitivity for detecting dementia, while a score of less than 82 has 93% sensitivity and 100% specificity. It has also been useful in differentiating dementia from pseudo dementia and detecting cognitive impairment in atypical Parkinson syndromes. However, while the test has shown 100% sensitivity and specificity in studies, its performance may vary in clinical practice.

For diagnostic categories to be useful, they must be related to the disorders encountered in practice. Face validity refers to the degree to which diagnostic categories align with clinical experience. Validity is distinct from diagnosis reliability. Concurrent validity measures how well a test corresponds with other measures of the same thing. Construct validity involves diagnostic categories indicating connections between disorders and independent variables, such as biochemical measures. Content validity involves test items representing the full range of possible items the test could cover. Predictive validity involves diagnostic categories being able to anticipate the outcome of disorders.

Delusional guilt is an intense feeling of remorse or guilt that lacks a rational basis and is often associated with depression. It is not classified as a primary delusion.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

SF-36: A Patient-Reported Survey for Measuring Functioning and Well-Being

The SF-36, also known as the Short-form 36, is a survey consisting of 36 items that patients can complete to rate their functioning and well-being. The survey is designed to measure eight different scales, with four pertaining to physical health and four to mental health. The physical health scales include physical functioning, role limitations due to physical health problems, bodily pain, and general health. The mental health scales include vitality (energy/fatigue), social functioning, role limitations due to emotional problems, and mental health (psychological distress and psychological well-being). Patients can complete the survey on their own, and it typically takes around eight minutes to finish.

These disorders can be caused by various factors, including neurological conditions, medication side effects, and metabolic imbalances. The following table outlines some of the key features of common movement disorders:

It is important to consider the underlying conditions and factors that may contribute to movement disorders in order to properly diagnose and treat these conditions.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

Interview Techniques: The Importance of Transition

Effective communication is crucial in any healthcare setting, particularly in psychiatry where patients may be hesitant to share personal information. One technique that can aid in the interview process is transition. Transition involves signaling to the patient that the interviewer has gathered enough information on a particular topic and is ready to move on to another subject.

Transition can be especially helpful when discussing sensitive of uncomfortable topics, as it allows the patient to feel heard and validated while also providing a sense of structure to the interview. Additionally, it can prevent the interview from becoming too focused on one topic, which may not be the most pressing concern for the patient.

It is important to use clear and concise language when transitioning to a new topic, and to ensure that the patient is comfortable with the change in direction. This can be achieved by asking if there is anything else they would like to add of if they have any questions before moving on.

Overall, incorporating transition into the interview process can improve communication and help patients feel more comfortable sharing their experiences and concerns.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Understanding Wilson’s Disease: Causes, Symptoms, and Management

Wilson’s disease, also known as hepatolenticular degeneration, is a genetic disorder that affects copper storage in the body. This condition is caused by a defect in the ATP7B gene, which leads to the accumulation of copper in the liver and brain. The onset of symptoms usually occurs between the ages of 10 and 25, with liver disease being the most common presentation in children and neurological symptoms in young adults.

The excessive deposition of copper in the tissues can cause a range of symptoms, including hepatitis, cirrhosis, basal ganglia degeneration, speech and behavioral problems, asterixis, chorea, dementia, Kayser-Fleischer rings, sunflower cataract, renal tubular acidosis, haemolysis, and blue nails. Diagnosis is based on reduced serum ceruloplasmin, reduced serum copper, and increased 24-hour urinary copper excretion.

The traditional first-line treatment for Wilson’s disease is penicillamine, which chelates copper. Trientine hydrochloride is an alternative chelating agent that may become first-line treatment in the future. Tetrathiomolybdate is a newer agent that is currently under investigation.

In summary, Wilson’s disease is a genetic disorder that affects copper storage in the body, leading to a range of symptoms that can affect the liver, brain, and eyes. Early diagnosis and treatment are essential to prevent complications and improve outcomes.

It is important to note that chorea and athetosis are two distinct movement disorders that are often confused. In chorea, the movements are characterized by quick, jerky motions, while in athetosis, there is a continuous flow of movement that is often described as worm-like. Athetosis involves a smooth, writhing motion, whereas chorea is more dance-like, with discrete movements that are not as continuous as those seen in athetosis.

It is probable that the patient is experiencing hyponatremia due to psychogenic polydipsia, while diabetes mellitus can be ruled out as their blood glucose level is normal. Additionally, lithium toxicity is an unlikely cause as lithium is not typically prescribed for schizophrenia treatment.

Psychogenic polydipsia is a condition where there is excessive consumption of fluids leading to polyuria, and it is commonly seen in psychiatric conditions such as schizophrenia and developmental disorders. The exact mechanism is unknown, but it is thought to be due to a defect in thirst and a dysfunction in AVP regulation. Patients with psychogenic polydipsia rarely complain of thirst but instead provide delusional explanations for their excessive drinking of state that drinking reduces their anxiety and makes them feel better. If fluid intake exceeds the capacity for excretion, then the resultant hyponatremia may produce signs of water intoxication. It is best managed by fluid restriction. Differential diagnosis should be done to rule out other causes of polyuria and polydipsia. Investigations such as fluid balance charts, urine dipstick, serum U&E and calcium, and urine and plasma osmolality should be arranged. Primary polydipsia can be subclassified into psychogenic and dipsogenic types.

The examiner’s use of minimal force to move the patient’s arm is an instance of automatic obedience, but it can be categorized more precisely as mitgehen, which represents a heightened form of automatic obedience.

Edinburgh Postnatal Depression Scale (EPDS)

The Edinburgh Postnatal Depression Scale (EPDS) is a 10-item self-report questionnaire designed to screen for postnatal depression in primary care settings. It should only be used to assess a women’s mood over the past seven days and cannot be used to diagnose depression. The EPDS excludes some symptoms common in the perinatal period, such as tiredness and irritability, as they do not differentiate between depressed and non-depressed postnatal women. Women are asked to select one of four responses that most closely represents how they have felt over the past seven days. Scores for the 10 items are added together, with a score of 0-9 indicating a low likelihood of depression, 10-12 indicating a moderate likelihood, and 13 of more indicating a high likelihood. The statements include feelings of happiness, sadness, anxiety, and thoughts of self-harm.

While open questions offer several benefits, they can pose challenges in terms of interview control and record-keeping.

Interview Techniques: Open and Closed Questions

When conducting an interview, it is important to use the appropriate types of questions. Open questions are designed to encourage a detailed response and can help to open up the conversation. In contrast, closed questions typically result in a yes of no answer and are useful for clarifying specific details. By using a combination of open and closed questions, interviewers can gather more information and gain a better understanding of the interviewee’s perspective. It is important to use these techniques effectively to ensure a successful interview.

Hepatomegaly

Chronic alcohol abuse can lead to hepatomegaly, which is an enlargement of the liver. This can be detected on physical examination by palpating the liver below the right ribcage. Hepatomegaly can also be associated with other signs of liver disease, such as jaundice, spider naevi, and caput medusa. It is important for psychiatrists to be aware of these physical findings in patients with alcohol use disorder, as they may indicate the need for further medical evaluation and treatment.

The Dunning-Kruger effect refers to a phenomenon where individuals with limited skills of knowledge tend to overestimate their abilities, leading them to believe they are more competent than they actually are.

The Flynn Effect is the term used to describe the increase in standardised intelligence test scores over time. Research conducted by Flynn showed that IQ scores increased by 13.8 points between 1932 and 1978, which equates to a 0.3-point increase per year of approximately 3 points per decade. More recent studies have also supported the Flynn effect, with IQ score gains observed between 1972 and 2006. This means that an individual is likely to achieve a higher IQ score on an earlier version of a test than on the current version. In fact, the test will overestimate an individual’s IQ score by an average of 0.3 points per year between the year in which the test was normed and the year in which the test was administered.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Munchausen syndrome, also known as factitious disorder, is a condition where individuals intentionally fabricate of induce illness to assume the patient role. It was named by London physician Richard Asher in 1951, who observed patients reporting false symptoms such as abdominal pain, bleeding, and headaches. Conversion disorder, also known as dissociative disorder, is another term used to describe this condition. Ganser’s syndrome, which is not specifically mentioned in the ICD-11, was previously listed as a dissociative disorder and is often seen in forensic psychiatry. It is characterized by symptoms such as approximate answers, hallucinations, clouded consciousness, and insensitivity to pain, and is usually acute and self-limiting. Patients may not remember experiencing the syndrome.

Somatoform and dissociative disorders are two groups of psychiatric disorders that are characterised by physical symptoms and disruptions in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behaviour. Somatoform disorders are characterised by physical symptoms that are presumed to have a psychiatric origin, while dissociative disorders are characterised by the loss of integration between memories, identity, immediate sensations, and control of bodily movements. The ICD-11 lists two main types of somatoform disorders: bodily distress disorder and body integrity dysphoria. The former involves bodily symptoms that the individual finds distressing and to which excessive attention is directed, while the latter involves a disturbance in the person’s experience of the body manifested by the persistent desire to have a specific physical disability accompanied by persistent discomfort of intense feelings of inappropriateness concerning current non-disabled body configuration. Dissociative disorders, on the other hand, are characterised by involuntary disruption of discontinuity in the normal integration of identity, sensations, perceptions, affects, thoughts, memories, control over bodily movements, of behaviour. The ICD-11 dissociative disorders include dissociative neurological symptom disorder, dissociative amnesia, trance disorder, possession trance disorder, dissociative identity disorder, partial dissociative identity disorder, depersonalization-derealization disorder, and other specified dissociative disorders. Each disorder has its own set of essential features and diagnostic criteria.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting. The CAGE is a well-known 4 question screening tool, but recent research has questioned its value. Other tools include SASQ (Single alcohol screening questionnaire), PAT (Paddington Alcohol Test), MAST (Michigan Alcoholism Screening Test), and RAPS4 (Rapid Alcohol Problem Screen 4). These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

Psychogenic polydipsia is a condition where there is excessive consumption of fluids leading to polyuria, and it is commonly seen in psychiatric conditions such as schizophrenia and developmental disorders. The exact mechanism is unknown, but it is thought to be due to a defect in thirst and a dysfunction in AVP regulation. Patients with psychogenic polydipsia rarely complain of thirst but instead provide delusional explanations for their excessive drinking of state that drinking reduces their anxiety and makes them feel better. If fluid intake exceeds the capacity for excretion, then the resultant hyponatremia may produce signs of water intoxication. It is best managed by fluid restriction. Differential diagnosis should be done to rule out other causes of polyuria and polydipsia. Investigations such as fluid balance charts, urine dipstick, serum U&E and calcium, and urine and plasma osmolality should be arranged. Primary polydipsia can be subclassified into psychogenic and dipsogenic types.

Although individuals with executive cognitive dysfunction may receive a normal score on the MMSE, they can still experience significant impairments in their daily functioning.

Mini Mental State Exam (MMSE)

The Mini Mental State Exam (MMSE) was developed in 1975 by Folstein et al. Its original purpose was to differentiate between organic and functional disorders, but it is now mainly used to detect and track the progression of cognitive impairment. The exam is scored out of 30 and is divided into seven categories: orientation to place and time, registration, attention and concentration, recall, language, visual construction, and attention to written command. Each category has a possible score, and the total score can indicate the severity of cognitive impairment. A score equal to or greater than 27 indicates normal cognition, while scores below this can indicate severe, moderate, of mild cognitive impairment. The MMSE is a useful tool for detecting and tracking cognitive impairment.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting. The CAGE is a well-known 4 question screening tool, but recent research has questioned its value. Other tools include SASQ (Single alcohol screening questionnaire), PAT (Paddington Alcohol Test), MAST (Michigan Alcoholism Screening Test), and RAPS4 (Rapid Alcohol Problem Screen 4). These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

Sudden delusional ideas are distinct from delusional perceptions as they do not arise from abnormal sensory experiences. There is no evidence of a paranoid environment. These delusions do not involve feeling persecuted. In persecutory delusions, the individual believes they are the object of aggression of surveillance. They may have delusions that they are in danger, insulted, ridiculed, monitored, of robbed by others who seek to harm their health, possessions, of life.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

The DSM-5 is a manual published by the American Psychiatric Association that categorizes mental health disorders for children and adults. In the UK, the equivalent is the ICD-10. The DSM-IV organized psychiatric diagnoses into five axes, including clinical syndromes (such as anorexia nervosa and schizophrenia), developmental and personality disorders, physical conditions that contribute to mental illness, psychosocial stressors, and the patient’s level of functioning.

The Positive and Negative Syndrome Scale (PANSS) is a tool used to measure the severity of symptoms in patients with schizophrenia. The scale is divided into three categories: positive symptoms, negative symptoms, and general psychopathology symptoms. Each category has several items that are scored on a seven-point severity scale. The positive symptoms include delusions, hallucinations, and hyperactivity, while the negative symptoms include blunted affect and lack of spontaneity. The general psychopathology symptoms include anxiety, depression, and poor impulse control. The PANSS is a valuable tool for clinicians to assess the severity of symptoms in patients with schizophrenia and to monitor their progress over time.

Although CAGE is commonly used for screening, it should not be used as a diagnostic tool. Additionally, it is not recommended to use CAGE as an outcome measure. AUDIT has been found to be more effective than CAGE and is the preferred screening tool according to the NICE Guidelines (CG115).

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting.

These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

Movement Disorders: Key Features

Movement disorders refer to a range of conditions that affect voluntary muscle movements. These disorders can be caused by various factors, including neurological conditions, medication side effects, and metabolic imbalances. The following table outlines some of the key features of common movement disorders:

Akinesia: Absence of loss of control of voluntary muscle movements, often seen in severe Parkinson’s disease.

Bradykinesia: Slowness of voluntary movement, a core symptom of Parkinson’s disease.

Akathisia: Subjective feeling of inner restlessness, often caused by antipsychotic medication use.

Athetosis: Continuous stream of slow, flowing, writhing involuntary movements, often seen in cerebral palsy, stroke, and Huntington’s disease.

Chorea: Brief, quasi-purposeful, irregular contractions that appear to flow from one muscle to the next, often seen in Huntington’s disease and Wilson’s disease.

Dystonia: Involuntary sustained of intermittent muscle contractions that cause twisting and repetitive movements, abnormal postures, of both.

Dyskinesia: General term referring to problems with voluntary movements and the presence of involuntary movements, often drug-induced.

Myoclonus: A sequence of repeated, often non-rhythmic, brief shock-like jerks due to sudden involuntary contraction of relaxation of one of more muscles.

Parkinsonism: Syndrome characterized by tremor, rigidity, and bradykinesia.

Tic: Sudden, repetitive, non-rhythmic, stereotyped motor movement of vocalization involving discrete muscle groups, often seen in Tourette’s syndrome.

Tremor: Involuntary, rhythmic, alternating movement of one of more body parts, often seen in essential tremor, Parkinson’s disease, and alcohol withdrawal.

Hemiballismus: Repetitive, but constantly varying, large amplitude involuntary movements of the proximal parts of the limbs, often seen in stroke and traumatic brain injury.

Stereotypies: Repetitive, simple movements that can be voluntarily suppressed, often seen in autism and intellectual disability.

It is important to consider the underlying conditions and factors that may contribute to movement disorders in order to properly diagnose and treat these conditions.

If the question had been about a female patient with learning difficulties, the pharmacological management of epilepsy may need to be adjusted based on factors such as hormonal changes and potential interactions with birth control medication.

Epilepsy: An Overview

Epilepsy is a condition that is diagnosed when a person experiences at least two unprovoked seizures that occur more than 24 hours apart. In the UK, the prevalence of epilepsy is 5-10 cases per 1000. Seizure types are categorized as focal onset of generalized onset. Focal seizures only involve a localized part of the brain, while generalized seizures involve the whole of both hemispheres. Temporal lobe epilepsy is the most common type of focal epilepsy, accounting for 60-70% of cases.

In 60% of people with epilepsy, there is no identifiable cause. Approximately 70% of people with epilepsy achieve remission, meaning they have no seizures for 5 years on of off treatment. of those with convulsive seizures, 2/3 have focal epilepsies and secondary generalized seizures, while the other 1/3 have generalized tonic-clonic seizures.

The National Institute for Health and Care Excellence (NICE) recommends treatment with antiepileptic drugs (AEDs) after a second epileptic seizure. For newly diagnosed focal seizures, carbamazepine of lamotrigine are recommended as first-line treatment. Levetiracetam, oxcarbazepine, of sodium valproate may be offered if carbamazepine and lamotrigine are unsuitable of not tolerated. For newly diagnosed generalized tonic-clonic seizures, sodium valproate is recommended as first-line treatment, with lamotrigine as an alternative if sodium valproate is unsuitable. For absence seizures, ethosuximide of sodium valproate are recommended as first-line treatment. For myoclonic seizures, sodium valproate is recommended as first-line treatment, and for tonic of atonic seizures, sodium valproate is also recommended as first-line treatment.

The distinguishing factors between the two are based on personal interpretation and tangible versus intangible concepts.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

The perception of an image is created from the stimulus of dirt, which is known as a pareidolic illusion. These illusions tend to fade as concentration decreases.

The Magical Number Seven, Plus of Minus Two: Some Limits on Our Capacity for Processing Information

Miller’s (1956) study focused on the limits of our short-term memory capacity, specifically in regards to our ability to recall sequences of numbers. The digit span test, which involves repeating back increasingly longer sequences of numbers both forwards and backwards, is used to measure this capacity. Miller found that the normal range for Digit Span forward was a maximum span of 7±2 digits. This study highlights the limitations of our short-term memory and the importance of understanding these limitations in various contexts, such as education and cognitive psychology.

In psychiatry, various questionnaires and interviews are used to assess different conditions and areas. It is important for candidates to know whether certain assessment tools are self-rated of require clinical assistance. The table provided by the college lists some of the commonly used assessment tools and indicates whether they are self-rated of clinician-rated. For example, the HAMD and MADRS are clinician-rated scales used to assess the severity of depression, while the GDS is a self-rated scale used to screen for depression in the elderly. The YMRS is a clinician-rated scale used to assess the severity of mania in patients with bipolar disorder, while the Y-BOCS is used to measure both the severity of OCD and the response to treatment. The GAF provides a single measure of global functioning, while the CGI requires the clinician to rate the severity of the patient’s illness at the time of assessment. The CAMDEX is a tool developed to assist in the early diagnosis and measurement of dementia in the elderly.

The act of repeating phrases that one feels compelled to perform is considered a compulsion. Compulsions are actions, either physical or mental, that one feels driven to perform. Obsessions, on the other hand, are recurrent and intrusive thoughts, urges, of images. The urge to hoard, for example, is an obsession rather than a compulsion. Compulsions are not inherently pleasurable and are performed to reduce anxiety. It is important to note that in order to qualify as a compulsion under DSM-5, the behavior must be time-consuming (taking more than 1 hour per day) of cause significant distress of impairment in important areas of functioning. Therefore, the behavior that is most suggestive of a compulsion is one that meets these criteria.

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by the presence of either obsessions or compulsions, and often both. Obsessions are repetitive and persistent thoughts, images, of impulses that are intrusive and unwanted, while compulsions are repetitive behaviors of rituals that an individual feels driven to perform in response to an obsession of according to rigid rules. The symptoms can cause significant functional impairment and/of distress. To diagnose OCD, the essential features include the presence of persistent obsessions and/of compulsions that are time-consuming of result in significant distress of impairment in important areas of functioning. The symptoms cannot be attributed to another medical condition of the effects of a substance of medication on the central nervous system.

Assessing Executive Function with the Hayling and Brixton Tests

The Hayling and Brixton tests are two assessments designed to evaluate executive function. The Hayling Sentence Completion Test consists of two sets of 15 sentences, with the last word missing. In the first section, participants complete the sentences, providing a measure of response initiation speed. The second part, the Hayling, requires participants to complete a sentence with a nonsense ending word, suppressing a sensible one. This provides measures of response suppression ability and thinking time. Performance on such tests has been linked to frontal lobe dysfunction and dysexecutive symptoms in everyday life.

The Brixton Test is a rule detection and rule following task. Impairments on such tasks are commonly demonstrated in individuals with dysexecutive problems. Overall, these tests provide valuable insights into executive function and can help identify areas of weakness that may require intervention.

A positive Romberg test suggests the presence of sensory ataxia.

Romberg’s Test for Investigating Ataxia

Romberg’s test is a diagnostic tool used to determine the cause of ataxia. A positive result indicates that the cause is sensory in nature. The test involves asking the patient to stand upright with their feet together and eyes closed. If the patient begins to sway of fall over, the test is considered positive. In cases where there is a cerebellar problem, the patient will exhibit ataxia even when their eyes are open. Romberg’s test is an important tool in diagnosing ataxia and determining the underlying cause of the condition.

The women’s movements are being narrated in real-time by the voices, which is known as ‘running commentary’. It does not appear that the voices are affecting her thoughts in any way.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

This is an instance of a primary delusion known as delusional perception.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

Psychogenic polydipsia is a condition where there is excessive consumption of fluids leading to polyuria, and it is commonly seen in psychiatric conditions such as schizophrenia and developmental disorders. The exact mechanism is unknown, but it is thought to be due to a defect in thirst and a dysfunction in AVP regulation. Patients with psychogenic polydipsia rarely complain of thirst but instead provide delusional explanations for their excessive drinking of state that drinking reduces their anxiety and makes them feel better. If fluid intake exceeds the capacity for excretion, then the resultant hyponatremia may produce signs of water intoxication. It is best managed by fluid restriction. Differential diagnosis should be done to rule out other causes of polyuria and polydipsia. Investigations such as fluid balance charts, urine dipstick, serum U&E and calcium, and urine and plasma osmolality should be arranged. Primary polydipsia can be subclassified into psychogenic and dipsogenic types.

While other conditions may also present with the same symptoms, a Kayser-Fleischer Ring, characterized by a golden-brown corneal ring due to copper deposits at the Descemet’s membrane, is considered a definitive indicator of Wilson’s disease.

Understanding Wilson’s Disease: Causes, Symptoms, and Management

Wilson’s disease, also known as hepatolenticular degeneration, is a genetic disorder that affects copper storage in the body. This condition is caused by a defect in the ATP7B gene, which leads to the accumulation of copper in the liver and brain. The onset of symptoms usually occurs between the ages of 10 and 25, with liver disease being the most common presentation in children and neurological symptoms in young adults.

The excessive deposition of copper in the tissues can cause a range of symptoms, including hepatitis, cirrhosis, basal ganglia degeneration, speech and behavioral problems, asterixis, chorea, dementia, Kayser-Fleischer rings, sunflower cataract, renal tubular acidosis, haemolysis, and blue nails. Diagnosis is based on reduced serum ceruloplasmin, reduced serum copper, and increased 24-hour urinary copper excretion.

The traditional first-line treatment for Wilson’s disease is penicillamine, which chelates copper. Trientine hydrochloride is an alternative chelating agent that may become first-line treatment in the future. Tetrathiomolybdate is a newer agent that is currently under investigation.

In summary, Wilson’s disease is a genetic disorder that affects copper storage in the body, leading to a range of symptoms that can affect the liver, brain, and eyes. Early diagnosis and treatment are essential to prevent complications and improve outcomes.

Echolalia refers to the act of repeating someone else’s spoken words without any meaningful connection of context. This behavior is often observed in individuals with certain neurological of developmental disorders.

Formal Thought Disorders

In formal thought disorders, changes in the speed, coherence, and cogency of thought can be observed from a patient’s speech. These disorders can also be self-reported and may be accompanied by enhanced use of nonverbal language. One possible indication is a lack of an adequate connection between two consecutive thoughts, which is called ‘asyndesis’.

There are several types of formal thought disorders, including inhibited thinking, retarded thinking, circumstantial thinking, restricted thinking, perseverative thinking, rumination, pressured thinking, flight of ideas, tangential thinking, thought blocking, disruption of thought, incoherence/derailment, and neologisms.

Inhibited thinking is about the subjective experience of the patient, who may feel that their thinking process is slowed down of blocked by an inner wall of resistance. Retarded thinking, on the other hand, is about the observed quality of thought as inferred through speech, where the flow of thought processes is slowed down and sluggish.

Circumstantial thinking refers to an inability to separate the essential from the unessential during a conversation without rendering the conversation incoherent. Restricted thinking involves a limited range of thought content, fixation on one particular topic of a small number of topics only, and a stereotyped pattern of thinking.

Perseverative thinking is characterized by the persistent repetition of previously used words, phrases, of details to the point where they become meaningless in the context of the current stage of the interview. Rumination is the endless mental preoccupation with, of excessive concern over, mostly unpleasant thoughts.

Pressured thinking, also known as crowding of thought, is when the patient feels helplessly exposed to the pressures of floods of different ideas of thoughts. Flight of ideas involves an increasing multitude of thoughts and ideas which are no longer firmly guided by clear goal-directed thinking.

Tangential thinking occurs when the patient appears to understand the contents of the questions addressed to them but provides answers which are completely out of context. Thought blocking of disruption of thought refers to sudden disruption of an otherwise normal flow of thought of speech for no obvious reason.

Incoherence of derailment is when the interviewer is unable to establish sensible connections between the patient’s thinking and verbal output, which is sometimes also called derailment. Neologisms involve the formation of new words of usage of words which disregard normal conventions and are generally not easily understandable.

Kraepelin’s Mixed States: A Historical Overview

Kraepelin’s six types of mixed states were based on various combinations of mood, will, and thought processes. These mixed states are less common than pure mania of pure depression. Dysphoric mania and depressive mixed state are the two types of mixed states that have been reduced over the years. Other terms used to describe mixed states include agitated depression, anxious depression, irritable depression, and mixed hypomania. Despite the reduction in the number of mixed states, they remain a relevant psychopathological syndrome in modern times.

Understanding Prosody and Aprosodias

Prosody refers to the emotional tone of language, which is conveyed through the melodious quality and inflections in the voice. It is affected by various psychiatric and neuropsychiatric illnesses, and disorders in the ability to express of understand the emotional overlay of speech are called aprosodias. Aprosodias are typically caused by dysfunction in areas of the non-dominant hemisphere, usually the right side of the brain.

Executive aprosody, which is the ability to express emotions in speech, can be tested by asking the patient to repeat a neutral sentence with different emotions. It is affected by lesions of the right premotor cortex of the basal ganglia. On the other hand, receptive aprosody, which is the ability to understand emotions in speech, can be tested by asking the patient to identify the emotion conveyed in a neutral sentence with different emotional inflections. It is affected by lesions of the posterior superior right temporal lobe.

Abnormalities of prosody are not specific to any particular disorder, but patients with severe depression, schizophrenia, and pervasive developmental disorders often present with characteristic abnormalities of prosody. For instance, severely depressed patients may have a monotonous, affect-neutral pattern of speech, while patients with schizophrenia may present with abnormal modulation of emphasis and volume of unusual accents. Patients with autism and Asperger’s disorder may have speech patterns that are monotonous, robotic, of singsong in quality.

The main purpose of the ‘serial sevens’ is to evaluate an individual’s ability to focus and maintain attention. It also has a secondary function of assessing memory to some degree.

A score equal to or greater than 27 indicates normal cognition, while scores below this can indicate severe, moderate, of mild cognitive impairment. The MMSE is a useful tool for detecting and tracking cognitive impairment.

The question implies that obsessions are characterized by urges, images, of thoughts, while compulsions involve acts, either motor of mental. However, it is important to note that in order to be classified as an obsession of compulsion according to DSM-5 and ICD-11 criteria, the behavior must be time-consuming (taking more than 1 hour per day) of cause significant distress of impairment in important areas of functioning.

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by the presence of either obsessions or compulsions, and often both. Obsessions are repetitive and persistent thoughts, images, of impulses that are intrusive and unwanted, while compulsions are repetitive behaviors of rituals that an individual feels driven to perform in response to an obsession of according to rigid rules. The symptoms can cause significant functional impairment and/of distress. To diagnose OCD, the essential features include the presence of persistent obsessions and/of compulsions that are time-consuming of result in significant distress of impairment in important areas of functioning. The symptoms cannot be attributed to another medical condition of the effects of a substance of medication on the central nervous system.

The Raven’s Progressive Matrices test assesses general intelligence without the use of verbal language.

The field of psychiatry uses various cognitive tests to assess different areas of cognition, including premorbid intelligence, intelligence, memory, attention, language, and others. Some commonly used tests include the National Adult Reading Test (NART) for premorbid intelligence, the Wechsler Adult Intelligence scale (WAIS) and Raven’s Progressive Matrices for intelligence, the Rey-Osterrieth Complex Figure for memory, and the Stroop test, Wisconsin card sorting test, Tower of London, and Continuous Performance Tasks for attention. The Boston naming test and Animal fluency are used to assess language skills. The Halstead-Reitan battery is used specifically for assessing brain damage. These tests are often included in the MRCPsych exams.

It is important to note that myoclonus is a common occurrence when individuals are falling asleep and is not considered abnormal in this context. Tics share similarities with myoclonus, but one key difference is that tics can be partially suppressed.

Movement Disorders: Key Features

Movement disorders refer to a range of conditions that affect voluntary muscle movements. These disorders can be caused by various factors, including neurological conditions, medication side effects, and metabolic imbalances. The following table outlines some of the key features of common movement disorders:

Akinesia: Absence of loss of control of voluntary muscle movements, often seen in severe Parkinson’s disease.

Bradykinesia: Slowness of voluntary movement, a core symptom of Parkinson’s disease.

Akathisia: Subjective feeling of inner restlessness, often caused by antipsychotic medication use.

Athetosis: Continuous stream of slow, flowing, writhing involuntary movements, often seen in cerebral palsy, stroke, and Huntington’s disease.

Chorea: Brief, quasi-purposeful, irregular contractions that appear to flow from one muscle to the next, often seen in Huntington’s disease and Wilson’s disease.

Dystonia: Involuntary sustained of intermittent muscle contractions that cause twisting and repetitive movements, abnormal postures, of both.

Dyskinesia: General term referring to problems with voluntary movements and the presence of involuntary movements, often drug-induced.

Myoclonus: A sequence of repeated, often non-rhythmic, brief shock-like jerks due to sudden involuntary contraction of relaxation of one of more muscles.

Parkinsonism: Syndrome characterized by tremor, rigidity, and bradykinesia.

Tic: Sudden, repetitive, non-rhythmic, stereotyped motor movement of vocalization involving discrete muscle groups, often seen in Tourette’s syndrome.

Tremor: Involuntary, rhythmic, alternating movement of one of more body parts, often seen in essential tremor, Parkinson’s disease, and alcohol withdrawal.

Hemiballismus: Repetitive, but constantly varying, large amplitude involuntary movements of the proximal parts of the limbs, often seen in stroke and traumatic brain injury.

Stereotypies: Repetitive, simple movements that can be voluntarily suppressed, often seen in autism and intellectual disability.

It is important to consider the underlying conditions and factors that may contribute to movement disorders in order to properly diagnose and treat these conditions.

Migraine

Migraine is a common condition that affects 5-10% of the population, with a higher prevalence in women than men (2-3:1). It typically starts in childhood of adolescence and has a strong familial association, with 2/3 of cases reporting a family history of migraine.

The most prominent symptom of migraine is headache, which is usually unilateral but can occur on both sides. Other symptoms include anorexia, nausea and vomiting, photophobia, and intolerance of noise.

In about 1/3 of cases, migraines are preceded by a visual aura (known as classic migraine). The most common form of visual aura is the ‘fortification spectra’ (semicircle of zigzag lights), but other disturbances such as micropsia, macropsia, zoom vision, mosaic vision, scotomas, and even hallucinations can occur.

Basilar migraines are a subtype of migraine where headache and aura are accompanied by difficulty speaking, vertigo, ringing in ears, of other brainstem-related symptoms, but not motor weakness.

Migraine can be triggered by various factors, including alcohol, cheese, chocolate, skipping meals, missing sleep, and oral contraceptives. Stress is also a common precipitant of migraine.

Sick Euthyroid Syndrome: Abnormal Thyroid Function in Non-Thyroidal Illness

Sick euthyroid syndrome, also known as low T3 syndrome, is a condition where thyroid function tests show abnormal results, typically low T3 levels, while T4 and TSH levels remain normal. This condition is commonly observed in patients with non-thyroidal illness. For instance, individuals with anorexia who have undergone prolonged starvation may develop this syndrome.

The National Adult Reading Test as a Valid Measure of Premorbid Intelligence

The National Adult Reading Test (NART) is a reliable and valid assessment tool for measuring Premorbid intelligence. It comprises 50 words with irregular spellings, and the test-taker must correctly pronounce each word to receive a point. The NART is a useful tool for assessing cognitive function in individuals with neurological disorders of brain injuries, as it provides a baseline measure of their intellectual abilities before the onset of their condition. The NART is a widely used and respected measure of Premorbid intelligence, and its results can inform clinical decision-making and treatment planning.

Patients may feel that they have lost control over their thoughts, which can manifest as passivity of thought. This refers to the belief that an external agency is controlling one’s thoughts. Passivity can take different forms, such as thought withdrawal, thought insertion, and thought broadcasting.

Ego (Boundary) Disturbances

Ego (boundary) disturbances refer to experiences where there is a disturbance in the perception of self as distinct from the environment of the integrity of self. It also includes instances where bodily processes, personal thought processes, feelings, and actions are experienced as being externally directed. These phenomena are referred to as passivity phenomena, and some of the symptom characteristics are classified as bizarre delusional phenomena in the DSM.

Derealization is when a patient experiences their surroundings of time as if they are unreal and changed, losing all feelings of familiarity and trust in the environment. People, objects, and surroundings appear unreal, unfamiliar, of spatially altered. The sensations may be intense of weak in nature.

Depersonalization is when a patient perceives themselves as alien, unreal, changed, of as a stranger. The disturbances of depersonalization may be of a transient nature only of become more persistent over a longer period of time. It is generally felt to be both strange and unpleasant.

Thought broadcasting is when a patient’s personal thoughts are experienced as no longer belonging to the patient alone but accessible by others who will know what the patient is thinking (mind reading). Thought withdrawal is when a patient’s thoughts are being removed of stripped from them. Thought insertion is when patients experience their thoughts and ideas as being externally influenced, made externally, controlled, directed, entered/ of externally imposed.

Other feelings of alien influence refer to feelings, intentions, behavior, of bodily functions that are experienced as externally controlled of made by others (passivity phenomena). The patient feels externally compelled to say something specific, to scream, to act of behave in a particular way, to attack someone, to throw a tantrum, etc.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

The NART is a widely accepted assessment tool utilized for approximating an individual’s intelligence level prior to the onset of any cognitive impairment.

The field of psychiatry uses various cognitive tests to assess different areas of cognition, including premorbid intelligence, intelligence, memory, attention, language, and others. Some commonly used tests include the National Adult Reading Test (NART) for premorbid intelligence, the Wechsler Adult Intelligence scale (WAIS) and Raven’s Progressive Matrices for intelligence, the Rey-Osterrieth Complex Figure for memory, and the Stroop test, Wisconsin card sorting test, Tower of London, and Continuous Performance Tasks for attention.

This condition is caused by a defect in the ATP7B gene, which leads to the accumulation of copper in the liver and brain. The onset of symptoms usually occurs between the ages of 10 and 25, with liver disease being the most common presentation in children and neurological symptoms in young adults.

The excessive deposition of copper in the tissues can cause a range of symptoms, including hepatitis, cirrhosis, basal ganglia degeneration, speech and behavioral problems, asterixis, chorea, dementia, Kayser-Fleischer rings, sunflower cataract, renal tubular acidosis, haemolysis, and blue nails. Diagnosis is based on reduced serum ceruloplasmin, reduced serum copper, and increased 24-hour urinary copper excretion.

The traditional first-line treatment for Wilson’s disease is penicillamine, which chelates copper. Trientine hydrochloride is an alternative chelating agent that may become first-line treatment in the future. Tetrathiomolybdate is a newer agent that is currently under investigation.

In summary, Wilson’s disease is a genetic disorder that affects copper storage in the body, leading to a range of symptoms that can affect the liver, brain, and eyes. Early diagnosis and treatment are essential to prevent complications and improve outcomes.

The National Adult Reading Test as a Valid Measure of Premorbid Intelligence

The National Adult Reading Test (NART) is a reliable and valid assessment tool for measuring premorbid intelligence. It comprises 50 words with irregular spellings, and the test-taker must correctly pronounce each word to receive a point. The NART is a useful tool for assessing cognitive function in individuals with neurological disorders of brain injuries, as it provides a baseline measure of their intellectual abilities before the onset of their condition. The NART is a widely used and respected measure of premorbid intelligence, and its results can inform clinical decision-making and treatment planning.

The Addenbrooke’s Cognitive Exam: A Brief Screening Tool for Dementia

The Addenbrooke’s cognitive examination (ACE) is a cognitive screening tool developed to detect dementia and differentiate Alzheimer’s dementia from frontotemporal dementia. It was created to address the limitations of the MMSE, which lacked sensitivity for frontal-executive dysfunction and visuospatial defects. The ACE is a brief test that takes 15-20 minutes to administer and is divided into five domains: attention and orientation, memory, verbal fluency, language, and visuospatial abilities. The total score is based on a maximum score of 100, with higher scores indicating better cognitive functioning.

The ACE has been shown to be a valid tool for detecting dementia, with two cut-off points often used depending on the required sensitivity and specificity. A score of less than 88 has 100% sensitivity for detecting dementia, while a score of less than 82 has 93% sensitivity and 100% specificity. It has also been useful in differentiating dementia from pseudo dementia and detecting cognitive impairment in atypical Parkinson syndromes. However, while the test has shown 100% sensitivity and specificity in studies, its performance may vary in clinical practice.

The structure of a delusion is not described by the term grandiose, but rather the content.

Delusional Structure

Delusions can be categorized based on their logical consistency and organization. Logical delusions are consistent with logical thinking, while paralogical delusions are not. Delusions can also be organized, integrated into a formed concept, of unorganized. Highly organized, logical delusions are referred to as systematized.

The relationship between delusional beliefs and reality can also be described in different ways. Polarized delusions mix fact and delusion together, while juxtaposed delusions exist side by side with facts but do not interact. Autistic delusions completely disregard actual reality, and the patient lives in a delusional world.

Mental State Exam – Mood and Affect

Affect is a term used to describe a patient’s present emotional responsiveness, which is indicated by their facial expression and tone of voice. It can be described as being within normal range, constricted (where the affect is restricted in range and intensity), blunted (similar to constricted but a bit more so), of flat (where there are virtually no signs of affective expression). Mood, on the other hand, is a more prolonged prevailing state of disposition. A feeling is an active experience of somatic sensation of a passive subjective experience of an emotion, while an emotion is best thought of as a feeling and memory intertwined. Apathy is the absence of feeling. It is important to distinguish between affect and mood, as affect is momentary and mood is more prolonged.

Clinical Trials: Phases and Objectives

Clinical trials are conducted in four phases to evaluate the safety and efficacy of drugs of treatments. In Phase I, a small group of healthy individuals (15-20) is given the drug to determine its safety, dosage range, and side effects. Phase II involves a larger group (100-300) to assess the drug’s effectiveness and safety. In Phase III, the drug is given to a larger population (1,000-3,000) to confirm its efficacy, compare it with existing treatments, and collect data for safe use. Phase IV, also known as post-marketing trials, is conducted after the drug is licensed to gather additional information on safety and potential uses. These trials are crucial in determining the safety and efficacy of drugs and treatments before they are made available to the public.

Personality Disorder Classification

A personality disorder is a persistent pattern of behavior and inner experience that deviates significantly from cultural expectations, is inflexible and pervasive, and causes distress of impairment. The DSM-5 and ICD-11 have different approaches to classifying personality disorders. DSM-5 divides them into 10 categories, grouped into clusters A, B, and C, while ICD-11 has a general category with six trait domains that can be added. To diagnose a personality disorder, the general diagnostic threshold must be met before determining the subtype(s) present. The criteria for diagnosis include inflexibility and pervasiveness of the pattern, onset in adolescence of early adulthood, stability over time, and significant distress of impairment. The disturbance must not be better explained by another mental disorder, substance misuse, of medical condition.

Course

Borderline and antisocial personality disorders tend to become less evident of remit with age, while others, particularly obsessive-compulsive and schizotypal, may persist.

Classification

The DSM-5 divides personality disorders into separate clusters A, B, and C, with additional groups for medical conditions and unspecified disorders. The ICD-11 dropped the separate categories and instead lists six trait domains that can be added to the general diagnosis.

UK Epidemiology

The prevalence of personality disorders in Great Britain, according to the British National Survey of Psychiatric Morbidity, is 4.4%, with cluster C being the most common at 2.6%, followed by cluster A at 1.6% and cluster B at 1.2%. The most prevalent specific personality disorder is obsessive-compulsive (anankastic) at 1.9%.

This scenario highlights the distinction between projection and projective identification. The woman is projecting her own sadness onto the cows, as she is unable to acknowledge of process her emotions. In projective identification, the recipient of the projection internalizes and identifies with the projected feelings. However, since it is impossible for the cows to experience human emotions, the correct term for this situation is projection.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

It is important to note that Carl Schneider should not be mistaken for Kurt Schneider. While Carl Schneider was a psychiatrist who had ties to the Nazi party and played a significant role in the Action T4 Euthanasia program, Kurt Schneider was a different individual altogether.

Patients with polydipsia tend to have a slower onset of symptoms and are less likely to report waking up at night to drink of urinate, in comparison to patients with conditions like diabetes insipidus (Fenske, 2012). Fenske’s (2012) clinical review discusses the current and future approaches to diagnosing diabetes insipidus.

Psychogenic polydipsia is a condition where there is excessive consumption of fluids leading to polyuria, and it is commonly seen in psychiatric conditions such as schizophrenia and developmental disorders. The exact mechanism is unknown, but it is thought to be due to a defect in thirst and a dysfunction in AVP regulation. Patients with psychogenic polydipsia rarely complain of thirst but instead provide delusional explanations for their excessive drinking of state that drinking reduces their anxiety and makes them feel better. If fluid intake exceeds the capacity for excretion, then the resultant hyponatremia may produce signs of water intoxication. It is best managed by fluid restriction. Differential diagnosis should be done to rule out other causes of polyuria and polydipsia. Investigations such as fluid balance charts, urine dipstick, serum U&E and calcium, and urine and plasma osmolality should be arranged. Primary polydipsia can be subclassified into psychogenic and dipsogenic types.

Assessment and Management of Obesity

Obesity is a condition that can increase the risk of various health problems, including type 2 diabetes, coronary heart disease, some types of cancer, and stroke. The body mass index (BMI) is a commonly used tool to assess obesity, calculated by dividing a person’s weight in kilograms by their height in meters squared. For adults over 20 years old, BMI falls into one of the following categories: underweight, normal of healthy weight, pre-obesity/overweight, obesity class I, obesity class II, and obesity class III.

Waist circumference can also be used in combination with BMI to guide interventions. Diet and exercise are the main interventions up to a BMI of 35, unless there are comorbidities such as type 2 diabetes, hypertension, cardiovascular disease, osteoarthritis, dyslipidemia, and sleep apnea. Physical activity recommendations suggest that adults should accumulate at least 150 minutes of moderate intensity activity of 75 minutes of vigorous intensity activity per week. Dietary recommendations suggest diets that have a 600 kcal/day deficit.

Pharmacological options such as Orlistat of Liraglutide may be considered for those with a BMI of 30 kg/m2 of more, of 28 if associated risk factors. Surgical options such as bariatric surgery may be considered for those with a BMI of 40 kg/m2 of more, of between 35 kg/m2 and 40 kg/m2 with other significant diseases that could be improved with weight loss.

Argyll Robertson Pupil: Accommodation Retained

The Argyll Robertson pupil is a notable topic in medical exams, as it is associated with tertiary syphilis, which is a crucial differential diagnosis for various psychiatric conditions like mood disorders, dementia, and psychosis. This type of pupil reacts poorly to light but normally to near stimuli, such as accommodation and convergence. They are typically small and irregular in shape, but they do not usually affect visual acuity. Mydriatic agents are not effective in dilating the Argyll Robertson pupil. Although this type of pupil is often considered pathognomonic of tertiary syphilis, it has also been observed in diabetes.

The field of psychiatry uses various cognitive tests to assess different areas of cognition, including premorbid intelligence, intelligence, memory, attention, language, and others. Some commonly used tests include the National Adult Reading Test (NART) for premorbid intelligence, the Wechsler Adult Intelligence scale (WAIS) and Raven’s Progressive Matrices for intelligence, the Rey-Osterrieth Complex Figure for memory, and the Stroop test, Wisconsin card sorting test, Tower of London, and Continuous Performance Tasks for attention. The Boston naming test and Animal fluency are used to assess language skills. The Halstead-Reitan battery is used specifically for assessing brain damage. These tests are often included in the MRCPsych exams.

Understanding Compound Questions in Interview Techniques

When conducting interviews, it is important to be aware of compound questions. These are questions that combine multiple inquiries into what appears to be a single question. Compound questions can be confusing for the interviewee and may lead to inaccurate of incomplete responses.

To avoid compound questions, it is important to break down inquiries into separate, clear questions. This allows the interviewee to fully understand what is being asked and provide a thoughtful response. Additionally, it is important to avoid using conjunctions such as and of of when asking questions, as this can create compound questions.

By using clear and concise language and avoiding compound questions, interviewers can ensure that they are receiving accurate and complete responses from their interviewees. This can lead to a more successful and informative interview process.

Lewis’ Views on Mental Illness Diagnosis

Lewis believed that mental illness could be understood by examining the disturbance of part functions of the brain, such as emotion, perception, and memory, as well as a reduction in general efficiency. However, he cautioned against using socially deviant behavior as a means of diagnosis. Instead, he advocated for a multi-axial formulation approach, which was first proposed by Essen-Möller in 1947. Lewis also warned against relying on response to psychotropic medication as a reliable method of diagnosis. Overall, Lewis emphasized the importance of a comprehensive and nuanced approach to diagnosing mental illness.

The score is 11, with E2, V4, and M5 contributing to it.

The Glasgow Coma Scale is used to assess the depth of coma and impaired consciousness. Scores range from 3 to 15, with impaired consciousness rated as mild, moderate, of severe. The scale assesses eye opening response, verbal response, and motor response, with specific criteria for scoring each behavior. The final score is a combination of these three scores.
Scoring Guide;

Synaesthesia is a condition in which stimulation of one sensory pathway results in experiences in another sensory pathway, such as perceiving a scent as a sound of visualizing a sound as a color.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

Psychogenic polydipsia is a condition where there is excessive consumption of fluids leading to polyuria, and it is commonly seen in psychiatric conditions such as schizophrenia and developmental disorders. The exact mechanism is unknown, but it is thought to be due to a defect in thirst and a dysfunction in AVP regulation.

Primary polydipsia can be subclassified into psychogenic and dipsogenic types.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting. The CAGE is a well-known 4 question screening tool, but recent research has questioned its value. Other tools include SASQ (Single alcohol screening questionnaire), PAT (Paddington Alcohol Test), MAST (Michigan Alcoholism Screening Test), and RAPS4 (Rapid Alcohol Problem Screen 4). These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

Alcohol Dependence Blood Profile

Alcohol dependence can have a significant impact on an individual’s blood profile. Several markers tend to be elevated in individuals with alcohol dependence, including GGT, AST, MCV, and ALT. Among these markers, GGT is considered the most reliable indicator of recent alcohol use. This means that elevated levels of GGT in the blood can suggest that an individual has consumed alcohol recently.

It is important to note that these blood markers may not be elevated in all individuals with alcohol dependence, and other factors can also contribute to changes in blood profile. However, monitoring these markers can be useful in assessing an individual’s alcohol use and identifying potential health risks associated with alcohol dependence. Healthcare professionals can use this information to develop appropriate treatment plans and support individuals in managing their alcohol use.

Types of Delusions

Delusions come in many different forms. It is important to familiarize oneself with these types as they may be tested in an exam. Some of the most common types of delusions include:

– Folie a deux: a shared delusion between two or more people
– Grandiose: belief that one has special powers, beliefs, of purpose
– Hypochondriacal: belief that something is physically wrong with the patient
– Ekbom’s syndrome: belief that one has been infested with insects
– Othello syndrome: belief that a sexual partner is cheating on them
– Capgras delusion: belief that a person close to them has been replaced by a double
– Fregoli delusion: patient identifies a familiar person (usually suspected to be a persecutor) in other people they meet
– Syndrome of subjective doubles: belief that doubles of him/her exist
– Lycanthropy: belief that one has been transformed into an animal
– De Clérambault’s syndrome: false belief that a person is in love with them
– Cotard’s syndrome/nihilistic delusions: belief that they are dead of do not exist
– Referential: belief that others/TV/radio are speaking directly to of about the patient
– Delusional perception: belief that a normal percept (product of perception) has a special meaning
– Pseudocyesis: a condition whereby a woman believes herself to be pregnant when she is not. Objective signs accompany the belief such as abdominal enlargement, menstrual disturbance, apparent foetal movements, nausea, breast changes, and labour pains.

Remembering these types of delusions can be helpful in understanding and diagnosing patients with delusional disorders.

Senile Pupil: A Common Age-Related Condition

The senile pupil, also known as senile miosis, is a condition commonly observed in older individuals. It is characterized by a small pupil that does not dilate in the dark, and may also be associated with reduced reaction to light and accommodation. This condition is often a result of age-related changes in the muscles that control the pupil, and can be exacerbated by certain medications of medical conditions. While it may not cause significant vision problems, it is important for individuals with senile pupil to have regular eye exams to monitor any changes in their vision and ensure proper eye health.

The mental state exam assesses various areas of cognition, including orientation, attention/concentration, short term memory, long term memory, and executive function. Standard tests for each area include asking about time, place, and person for orientation, serial 7’s for attention/concentration, digit span for short term memory, delayed recall of name and address for long term memory, and various tasks such as proverbs, similarities, differences, verbal fluency, and cognitive estimates for executive function.

It is important to differentiate between the types of tremors seen in lithium toxicity and long-term lithium use. Coarse, intention tremor is associated with lithium toxicity, while fine, physiological tremor is seen in long-term lithium use. Remembering this distinction can help avoid confusion when assessing patients on lithium therapy.

Types of Tremor

Essential Tremor

Otherwise known as benign essential tremor, this is the most common type of tremor. It is not associated with any underlying pathology. It usually begins in the 40’s, affects mainly the hands, and is slowly progressive. It tends to worsen with heightened emotion. It usually presents with unilateral upper limb involvement then progresses to both limbs.

Parkinsonian Tremor

This tremor is associated with Parkinson’s disease. It is classically described as ‘pill rolling’ due to the characteristic appearance of the fingers.

Cerebellar Tremor

Otherwise known as an intention tremor. This is a slow, coarse tremor which gets worse with purposeful movement. This is seen in lithium toxicity (note that the tremor seen as a side effect of long term lithium is fine and classed as physiological).

Psychogenic Tremor

Also known as a hysterical tremor. This type of tremor tends to appear and disappear suddenly and is hard to characterise due to its changeable nature. It tends to improve with distraction.

Physiologic Tremor

This is a very-low-amplitude fine tremor that is barely visible to the naked eye. It is present in every normal person while maintaining a posture of movement. It becomes enhanced and visible in many conditions such as anxiety, hyperthyroidism, alcohol withdrawal, and as drug induced side effects.

It is useful to have a basic idea about the frequencies of different types of tremor.

Type of Tremor Frequency

Intention 2-3Hz

Parkinsonian 5Hz

Essential 7Hz

Physiological 10Hz

Psychogenic variable

The Flynn Effect is the term used to describe the increase in standardised intelligence test scores over time. Research conducted by Flynn showed that IQ scores increased by 13.8 points between 1932 and 1978, which equates to a 0.3-point increase per year of approximately 3 points per decade. More recent studies have also supported the Flynn effect, with IQ score gains observed between 1972 and 2006. This means that an individual is likely to achieve a higher IQ score on an earlier version of a test than on the current version. In fact, the test will overestimate an individual’s IQ score by an average of 0.3 points per year between the year in which the test was normed and the year in which the test was administered.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

Personality Disorder Classification

A personality disorder is a persistent pattern of behavior and inner experience that deviates significantly from cultural expectations, is inflexible and pervasive, and causes distress of impairment. The DSM-5 and ICD-11 have different approaches to classifying personality disorders. DSM-5 divides them into 10 categories, grouped into clusters A, B, and C, while ICD-11 has a general category with six trait domains that can be added. To diagnose a personality disorder, the general diagnostic threshold must be met before determining the subtype(s) present. The criteria for diagnosis include inflexibility and pervasiveness of the pattern, onset in adolescence of early adulthood, stability over time, and significant distress of impairment. The disturbance must not be better explained by another mental disorder, substance misuse, of medical condition.

The prevalence of personality disorders in Great Britain, according to the British National Survey of Psychiatric Morbidity, is 4.4%, with cluster C being the most common at 2.6%, followed by cluster A at 1.6% and cluster B at 1.2%. The most prevalent specific personality disorder is obsessive-compulsive (anankastic) at 1.9%.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Assessment and Management of Obesity

Obesity is a condition that can increase the risk of various health problems, including type 2 diabetes, coronary heart disease, some types of cancer, and stroke. The body mass index (BMI) is a commonly used tool to assess obesity, calculated by dividing a person’s weight in kilograms by their height in meters squared. For adults over 20 years old, BMI falls into one of the following categories: underweight, normal of healthy weight, pre-obesity/overweight, obesity class I, obesity class II, and obesity class III.

Waist circumference can also be used in combination with BMI to guide interventions. Diet and exercise are the main interventions up to a BMI of 35, unless there are comorbidities such as type 2 diabetes, hypertension, cardiovascular disease, osteoarthritis, dyslipidemia, and sleep apnea. Physical activity recommendations suggest that adults should accumulate at least 150 minutes of moderate intensity activity of 75 minutes of vigorous intensity activity per week. Dietary recommendations suggest diets that have a 600 kcal/day deficit.

Pharmacological options such as Orlistat of Liraglutide may be considered for those with a BMI of 30 kg/m2 of more, of 28 if associated risk factors. Surgical options such as bariatric surgery may be considered for those with a BMI of 40 kg/m2 of more, of between 35 kg/m2 and 40 kg/m2 with other significant diseases that could be improved with weight loss.

The question asks for the most suggestive option, and it should be noted that for something to be considered an obsession according to DSM-5 criteria, it must be time-consuming of cause significant distress of impairment in important areas of functioning. Obsessions can manifest as intrusive and unpleasant urges, thoughts, of images.

Obsessive-compulsive disorder (OCD) is a mental health condition characterized by the presence of either obsessions or compulsions, and often both. Obsessions are repetitive and persistent thoughts, images, of impulses that are intrusive and unwanted, while compulsions are repetitive behaviors of rituals that an individual feels driven to perform in response to an obsession of according to rigid rules. The symptoms can cause significant functional impairment and/of distress. To diagnose OCD, the essential features include the presence of persistent obsessions and/of compulsions that are time-consuming of result in significant distress of impairment in important areas of functioning. The symptoms cannot be attributed to another medical condition of the effects of a substance of medication on the central nervous system.

Although first rank symptoms are commonly associated with schizophrenia, they are not considered diagnostic of pathognomonic of the disorder, as they can also be present in other conditions. It is important to note that these symptoms were not originally designed for diagnostic purposes, but rather as a screening tool.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

Undoing and sublimation are two psychological concepts that are often mistaken for each other. While both involve a person’s attempt to deal with negative thoughts of emotions, there is a key difference between the two.

In undoing, a person tries to undo of neutralize their own unacceptable thoughts, emotions, of behaviors. This is often driven by feelings of guilt or remorse over something they have done of felt. The goal is to make amends and alleviate the negative feelings associated with their actions.

On the other hand, sublimation involves turning negative emotions into positive ones. However, unlike undoing, the person does not necessarily feel guilty of remorseful about their emotions. Instead, they may see their emotions as justified and seek to channel them into more positive outlets.

Therefore, while both undoing and sublimation involve coping with negative emotions, the key difference lies in the underlying motivation and feelings associated with the process.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

The assessment of intersecting pentagons is included in the mini mental state exam, while the Glasgow Coma Scale (GCS) is primarily utilized to evaluate impaired consciousness resulting from factors like trauma and substance abuse.

The Glasgow Coma Scale is used to assess the depth of coma and impaired consciousness. Scores range from 3 to 15, with impaired consciousness rated as mild, moderate, of severe. The scale assesses eye opening response, verbal response, and motor response, with specific criteria for scoring each behavior. The final score is a combination of these three scores.

Koro and Kuru are two distinct conditions that should not be mistaken for each other. While Kuru is a prion disease that is well-known for its association with cannibalism in Papua New Guinea, Koro is a different condition altogether.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

Delusional Structure

Delusions can be categorized based on their logical consistency and organization. Logical delusions are consistent with logical thinking, while paralogical delusions are not. Delusions can also be organized, integrated into a formed concept, of unorganized. Highly organized, logical delusions are referred to as systematized.

The relationship between delusional beliefs and reality can also be described in different ways. Polarized delusions mix fact and delusion together, while juxtaposed delusions exist side by side with facts but do not interact. Autistic delusions completely disregard actual reality, and the patient lives in a delusional world.

Understanding Hypercalcemia and its Causes

Hypercalcemia is a medical condition that can cause fatigue, confusion, and depression. It is characterized by the classic symptoms of bone pain, abdominal pain, renal stones, and psychic moans. This condition can be triggered by the use of lithium and thiazide diuretics.

It is important to note that around 50% of serum calcium is bound to plasma proteins, particularly albumin. This means that any abnormalities in albumin levels can lead to inaccurate calcium results. To address this issue, a corrected calcium test is usually included in a patient’s blood work to ensure accurate diagnosis and treatment.

The mother seems to transfer her own feelings of insecurity onto her daughter, who internalizes them even though she has a healthy weight. This phenomenon is known as projective identification, where the projected emotions are adopted and experienced as one’s own.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

The Stroop test involves presenting words to the subject that spell a color but are written in a different color. The subject is required to identify the color of the text as quickly as possible, rather than reading the word itself. This test assesses the subject’s ability to make an appropriate response when presented with conflicting signals. This ability is believed to originate from the anterior cingulate, which is located between the left and right frontal lobes.

Frontal Lobe Tests

The frontal lobe is responsible for a variety of cognitive functions, including initiation, abstraction, problem-solving, decision-making, response inhibition, and set shifting. Different tests can be used to assess these functions.

Verbal and categorical fluency tests can be used to assess initiation. These tests require individuals to generate as many words of items as possible within a specific category of starting letter.

Proverbs, similarities, and cognitive estimates are examples of tests that can be used to assess abstraction. These tests require individuals to identify similarities between objects of concepts, make judgments based on incomplete information, of estimate quantities.

Tower of London, Cambridge stockings, and gambling tasks are examples of tests that can be used to assess problem-solving and decision-making. These tests require individuals to plan and execute a sequence of actions to achieve a goal of make decisions based on uncertain outcomes.

Alternating sequences, go-no-go test, Luria motor test, trail making test, Wisconsin card sorting test, and Stroop test are examples of tests that can be used to assess response inhibition and set shifting. These tests require individuals to inhibit prepotent responses, switch between tasks of mental sets, of ignore irrelevant information.

Overall, these tests can provide valuable information about an individual’s frontal lobe functioning and can be used to diagnose and treat various neurological and psychiatric conditions.

Based on the patient’s dementia history, the diagnosis is supported.

Argyll Robertson Pupil: Accommodation Retained

The Argyll Robertson pupil is a notable topic in medical exams, as it is associated with tertiary syphilis, which is a crucial differential diagnosis for various psychiatric conditions like mood disorders, dementia, and psychosis. This type of pupil reacts poorly to light but normally to near stimuli, such as accommodation and convergence. They are typically small and irregular in shape, but they do not usually affect visual acuity. Mydriatic agents are not effective in dilating the Argyll Robertson pupil. Although this type of pupil is often considered pathognomonic of tertiary syphilis, it has also been observed in diabetes.

The term paramnesia refers to memory disorders where fantasy and reality are confused. There are various types of paramnesias, including déjà vu, jamais vu, confabulation, reduplicative paramnesia, retrospective falsification, and cryptomnesia. Reduplicative paramnesia is a subset of delusional misidentification syndromes, which include Capgras delusion, the Fregoli delusion, and others. A review of reduplicative paramnesia was conducted by Politis in 2012.

Types of Delusions

Delusions come in many different forms. It is important to familiarize oneself with these types as they may be tested in an exam. Some of the most common types of delusions include:

– Folie a deux: a shared delusion between two or more people
– Grandiose: belief that one has special powers, beliefs, of purpose
– Hypochondriacal: belief that something is physically wrong with the patient
– Ekbom’s syndrome: belief that one has been infested with insects
– Othello syndrome: belief that a sexual partner is cheating on them
– Capgras delusion: belief that a person close to them has been replaced by a double
– Fregoli delusion: patient identifies a familiar person (usually suspected to be a persecutor) in other people they meet
– Syndrome of subjective doubles: belief that doubles of him/her exist
– Lycanthropy: belief that one has been transformed into an animal
– De Clérambault’s syndrome: false belief that a person is in love with them
– Cotard’s syndrome/nihilistic delusions: belief that they are dead of do not exist
– Referential: belief that others/TV/radio are speaking directly to of about the patient
– Delusional perception: belief that a normal percept (product of perception) has a special meaning
– Pseudocyesis: a condition whereby a woman believes herself to be pregnant when she is not. Objective signs accompany the belief such as abdominal enlargement, menstrual disturbance, apparent foetal movements, nausea, breast changes, and labour pains.

Remembering these types of delusions can be helpful in understanding and diagnosing patients with delusional disorders.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Interview Techniques: Open and Closed Questions

When conducting an interview, it is important to use the appropriate types of questions. Open questions are designed to encourage a detailed response and can help to open up the conversation. In contrast, closed questions typically result in a yes of no answer and are useful for clarifying specific details. By using a combination of open and closed questions, interviewers can gather more information and gain a better understanding of the interviewee’s perspective. It is important to use these techniques effectively to ensure a successful interview.

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Dysmegalopsia: Difficulty in Perceiving Object Size

Dysmegalopsia is a condition characterized by a reduced ability to accurately perceive the size of objects. This can manifest as either micropsia, where objects appear smaller than they actually are, of macropsia, where objects appear larger than they actually are. Dysmegalopsia can occur as a standalone symptom of as part of a group of symptoms known as the Alice in Wonderland Syndrome. In this syndrome, individuals may experience distortions in their perception of size, shape, and distance, as well as other sensory disturbances. Dysmegalopsia can be caused by various factors, including neurological conditions, migraines, and the use of certain medications.

The ACE-III is a tool used to evaluate for dementia, but it does not screen for delirium. A diagnosis of dementia is typically made if the score falls between 82-88 out of 100. The original ACE included the MMSE, which allowed for a score to be calculated. However, some items on the MMSE, such as repeating the phrase no ifs, ands, of buts and spelling words backwards, were found to be problematic and have since been replaced. Therefore, it is no longer possible to derive an MMSE score from the ACE.

The Addenbrooke’s Cognitive Exam: A Brief Screening Tool for Dementia

The Addenbrooke’s cognitive examination (ACE) is a cognitive screening tool developed to detect dementia and differentiate Alzheimer’s dementia from frontotemporal dementia. It was created to address the limitations of the MMSE, which lacked sensitivity for frontal-executive dysfunction and visuospatial defects. The ACE is a brief test that takes 15-20 minutes to administer and is divided into five domains: attention and orientation, memory, verbal fluency, language, and visuospatial abilities. The total score is based on a maximum score of 100, with higher scores indicating better cognitive functioning.

The ACE has been shown to be a valid tool for detecting dementia, with two cut-off points often used depending on the required sensitivity and specificity. A score of less than 88 has 100% sensitivity for detecting dementia, while a score of less than 82 has 93% sensitivity and 100% specificity. It has also been useful in differentiating dementia from pseudo dementia and detecting cognitive impairment in atypical Parkinson syndromes. However, while the test has shown 100% sensitivity and specificity in studies, its performance may vary in clinical practice.

The initial release of DSM was in 1952, while ICD-6 was the first edition of ICD or DSM to incorporate classifications for mental illness, which was published in 1948. DSM-5 was the most recent version published in 2013, and ICD-11 is anticipated to be released in 2015.

The DSM-5 includes a distinct classification for narcissistic personality disorder.

Personality Disorder Classification

A personality disorder is a persistent pattern of behavior and inner experience that deviates significantly from cultural expectations, is inflexible and pervasive, and causes distress of impairment. The DSM-5 and ICD-11 have different approaches to classifying personality disorders. DSM-5 divides them into 10 categories, grouped into clusters A, B, and C, while ICD-11 has a general category with six trait domains that can be added. To diagnose a personality disorder, the general diagnostic threshold must be met before determining the subtype(s) present. The criteria for diagnosis include inflexibility and pervasiveness of the pattern, onset in adolescence of early adulthood, stability over time, and significant distress of impairment. The disturbance must not be better explained by another mental disorder, substance misuse, of medical condition.

Course

Borderline and antisocial personality disorders tend to become less evident of remit with age, while others, particularly obsessive-compulsive and schizotypal, may persist.

Classification

The DSM-5 divides personality disorders into separate clusters A, B, and C, with additional groups for medical conditions and unspecified disorders. The ICD-11 dropped the separate categories and instead lists six trait domains that can be added to the general diagnosis.

UK Epidemiology

The prevalence of personality disorders in Great Britain, according to the British National Survey of Psychiatric Morbidity, is 4.4%, with cluster C being the most common at 2.6%, followed by cluster A at 1.6% and cluster B at 1.2%. The most prevalent specific personality disorder is obsessive-compulsive (anankastic) at 1.9%.

Clifton Assessment Procedure (CAPE) is a valuable tool for evaluating the quality of life, cognitive impairments, and physical dependency levels in elderly individuals. It is used to identify areas of unmet needs and can be administered in both hospital and community settings. The assessment takes approximately 15-25 minutes to complete and comprises two scales: the cognitive assessment scale and the behavior rating scale. The cognitive assessment scale evaluates orientation, basic cognition, and psychomotor performance, while the behavior rating scale assesses physical dependency and behavioral problems. The CAPE can differentiate between organic brain disease and functional psychiatric disorders and predict the likelihood of hospital discharge. It is commonly used to determine the most appropriate placement for elderly individuals.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

Migraine

Migraine is a common condition that affects 5-10% of the population, with a higher prevalence in women than men (2-3:1). It typically starts in childhood of adolescence and has a strong familial association, with 2/3 of cases reporting a family history of migraine.

The most prominent symptom of migraine is headache, which is usually unilateral but can occur on both sides. Other symptoms include anorexia, nausea and vomiting, photophobia, and intolerance of noise.

In about 1/3 of cases, migraines are preceded by a visual aura (known as classic migraine). The most common form of visual aura is the ‘fortification spectra’ (semicircle of zigzag lights), but other disturbances such as micropsia, macropsia, zoom vision, mosaic vision, scotomas, and even hallucinations can occur.

Basilar migraines are a subtype of migraine where headache and aura are accompanied by difficulty speaking, vertigo, ringing in ears, of other brainstem-related symptoms, but not motor weakness.

Migraine can be triggered by various factors, including alcohol, cheese, chocolate, skipping meals, missing sleep, and oral contraceptives. Stress is also a common precipitant of migraine.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

The main purpose of the ‘serial sevens’ is to evaluate an individual’s ability to focus and maintain attention. It also has a secondary function of assessing memory to some degree.

Mini Mental State Exam (MMSE)

The Mini Mental State Exam (MMSE) was developed in 1975 by Folstein et al. Its original purpose was to differentiate between organic and functional disorders, but it is now mainly used to detect and track the progression of cognitive impairment. The exam is scored out of 30 and is divided into seven categories: orientation to place and time, registration, attention and concentration, recall, language, visual construction, and attention to written command. Each category has a possible score, and the total score can indicate the severity of cognitive impairment. A score equal to or greater than 27 indicates normal cognition, while scores below this can indicate severe, moderate, of mild cognitive impairment. The MMSE is a useful tool for detecting and tracking cognitive impairment.

The term paramnesia refers to memory disorders where fantasy and reality are confused. There are various types of paramnesias, including déjà vu, jamais vu, confabulation, reduplicative paramnesia, retrospective falsification, and cryptomnesia. Reduplicative paramnesia is a subset of delusional misidentification syndromes, which include Capgras delusion, the Fregoli delusion, and others. A review of reduplicative paramnesia was conducted by Politis in 2012.

Interview Techniques: Confrontation

Confrontation is a technique that can be employed during patient interviews to draw their attention to a particular issue. However, it is crucial to use this technique with care as it can potentially lead to the patient becoming defensive of hostile. Therefore, it is essential to approach confrontation tactfully and with sensitivity. By doing so, the interviewer can effectively communicate their concerns to the patient without causing any unnecessary tension of conflict. Proper use of confrontation can help patients recognize and address problematic behaviors of attitudes, leading to positive outcomes in their treatment.

Unfortunately, the college requires candidates to have some understanding of the German language. It is also important to be familiar with certain German terms such as Gedankenlautwerden (thought echo), Gegenhalten (a condition where a patient resists all passive movements with the same amount of force as applied by the examiner), Schnauzkrampf (a facial expression resembling pouting that is sometimes observed in catatonic patients), and Vorbeigehen/vorbeireden (a symptom seen in Ganser syndrome where patients give approximate answers to questions, such as responding with 14 when asked how many fingers a man has).

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Sensory Distortions of Sound

Hyperacusis is a condition where an individual experiences an increased sensitivity to noise. This condition is commonly observed in people with anxiety and depressive disorders, as well as during a hangover of migraine. On the other hand, hypoacusis is a condition where an individual experiences a reduced sensitivity to sound. This condition is commonly observed in people with delirium and depression, where it is often accompanied by hyperacusis.

Formal Thought Disorders

In formal thought disorders, changes in the speed, coherence, and cogency of thought can be observed from a patient’s speech. These disorders can also be self-reported and may be accompanied by enhanced use of nonverbal language. One possible indication is a lack of an adequate connection between two consecutive thoughts, which is called ‘asyndesis’.

There are several types of formal thought disorders, including inhibited thinking, retarded thinking, circumstantial thinking, restricted thinking, perseverative thinking, rumination, pressured thinking, flight of ideas, tangential thinking, thought blocking, disruption of thought, incoherence/derailment, and neologisms.

Inhibited thinking is about the subjective experience of the patient, who may feel that their thinking process is slowed down of blocked by an inner wall of resistance. Retarded thinking, on the other hand, is about the observed quality of thought as inferred through speech, where the flow of thought processes is slowed down and sluggish.

Circumstantial thinking refers to an inability to separate the essential from the unessential during a conversation without rendering the conversation incoherent. Restricted thinking involves a limited range of thought content, fixation on one particular topic of a small number of topics only, and a stereotyped pattern of thinking.

Perseverative thinking is characterized by the persistent repetition of previously used words, phrases, of details to the point where they become meaningless in the context of the current stage of the interview. Rumination is the endless mental preoccupation with, of excessive concern over, mostly unpleasant thoughts.

Pressured thinking, also known as crowding of thought, is when the patient feels helplessly exposed to the pressures of floods of different ideas of thoughts. Flight of ideas involves an increasing multitude of thoughts and ideas which are no longer firmly guided by clear goal-directed thinking.

Tangential thinking occurs when the patient appears to understand the contents of the questions addressed to them but provides answers which are completely out of context. Thought blocking of disruption of thought refers to sudden disruption of an otherwise normal flow of thought of speech for no obvious reason.

Incoherence of derailment is when the interviewer is unable to establish sensible connections between the patient’s thinking and verbal output, which is sometimes also called derailment. Neologisms involve the formation of new words of usage of words which disregard normal conventions and are generally not easily understandable.

The Glasgow Coma Scale is used to assess the depth of coma and impaired consciousness. Scores range from 3 to 15, with impaired consciousness rated as mild, moderate, of severe. The scale assesses eye opening response, verbal response, and motor response, with specific criteria for scoring each behavior. The final score is a combination of these three scores.
Scoring Guide;

The ICD is designed to be accessible to a broader range of individuals than the DSM, including those with limited professional training. Therefore, the terminology used is generally less specialized.

DSM versus ICD: A Comparison of Mental Disorder Classifications

The DSM and ICD are two widely used classifications of mental disorders. While the ICD was initiated in Paris in 1900, the DSM-I was published in the USA in 1952 as a military classification of mental disorders. The ICD is intended for use by all health practitioners, while the DSM is primarily used by psychiatrists. The ICD is the official world classification, while the DSM is the official classification in the USA.

One major difference between the two classifications is their focus. The ICD has a major focus on clinical utility, with a planned reduction of the number of diagnoses in the upcoming ICD-11. On the other hand, the DSM tends to increase the number of diagnoses with each succeeding revision. Additionally, the ICD provides diagnostic descriptions and guidance but does not employ operational criteria, while the DSM depends on operational criteria.

It is important to note that the ICD has to be flexible and simple in the use of language to enable all practitioners, including those with very little formal qualifications in low- and middle-income countries, to be acceptable. Overall, understanding the differences between the DSM and ICD can help mental health practitioners choose the most appropriate classification for their needs.

Hebephrenic schizophrenia is a type of schizophrenia that is classified in the ICD-10 as having a greater emphasis on thought disorder than hallucinations, with erratic of disorganized behavior being prominent. The DSM-IV equivalent is disorganized schizophrenia. Catatonic schizophrenia is characterized by abnormalities in psychomotor function. Paranoid schizophrenia is characterized by paranoid delusions and auditory hallucinations. Simple schizophrenia is not a suitable option because it is a subtype of schizophrenia that is characterized by a decline in functioning as the only clear symptom. Undifferentiated schizophrenia refers to a presentation of schizophrenia that does not fit into a specific subtype.

Historical Classification of Schizophrenia

The classification of schizophrenia has evolved over time, with various individuals contributing to its development. In 1801, Phillippe Pinel used the term ‘demencé’ to describe the loss of mental abilities in chronically ill patients. Benedict Morel coined the term ‘demencé precocé’ in 1852 to describe young patients with premature dementia. Kahlbaum was the first to describe ‘paraphrenia hebetica’ in the 1860s, which was later elaborated as ‘hebephrenia’ by Hecker in 1871.

In 1893, Emil Kraepelin used the term dementia praecox to describe the condition, emphasizing the importance of delusions, hallucinations, impaired attention, thought incoherence, stereotyped movements and expressions, deterioration of emotional life, and a loss of drive as key symptoms. In 1908, Eugen Bleuler coined the term ‘schizophrenia’ to replace dementia praecox, denoting ‘a splitting of the psychic functions.’ Bleuler expanded the concept to include presentations that did not include a ‘terminal state.’

Bleuler introduced a distinction between basic and accessory symptoms and primary and secondary symptoms. Basic symptoms are necessarily present in any case of schizophrenia, while accessory symptoms may of may not occur. The fundamental features of schizophrenia were loosening of associations, disturbances of affectivity, ambivalence, and autism. The alteration of associations is the only symptom that Bleuler regarded as both basic and primary, and can thus be described as the core disturbance in the Bleulerian conception of schizophrenia.

In 1939, Langfeldt introduced the term ‘schizophreniform psychosis’ to describe patients with Bleulerian schizophrenia who did not follow a progressively deteriorating course. In the 1960s, Rado/Meehl introduced the term ‘schizotypy’ to recognize the concept of a continuum of spectrum of schizophrenia-related phenotypes. In the 1980s, Crow proposed a subclassification of schizophrenia, dividing patients into types I and II. Type I patients present with positive symptoms such as delusions and hallucinations, while type II patients present with negative symptoms such as affective flattening and poverty of speech.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

Movement Disorders: Key Features

Movement disorders refer to a range of conditions that affect voluntary muscle movements. These disorders can be caused by various factors, including neurological conditions, medication side effects, and metabolic imbalances. The following table outlines some of the key features of common movement disorders:

Akinesia: Absence of loss of control of voluntary muscle movements, often seen in severe Parkinson’s disease.

Bradykinesia: Slowness of voluntary movement, a core symptom of Parkinson’s disease.

Akathisia: Subjective feeling of inner restlessness, often caused by antipsychotic medication use.

Athetosis: Continuous stream of slow, flowing, writhing involuntary movements, often seen in cerebral palsy, stroke, and Huntington’s disease.

Chorea: Brief, quasi-purposeful, irregular contractions that appear to flow from one muscle to the next, often seen in Huntington’s disease and Wilson’s disease.

Dystonia: Involuntary sustained of intermittent muscle contractions that cause twisting and repetitive movements, abnormal postures, of both.

Dyskinesia: General term referring to problems with voluntary movements and the presence of involuntary movements, often drug-induced.

Myoclonus: A sequence of repeated, often non-rhythmic, brief shock-like jerks due to sudden involuntary contraction of relaxation of one of more muscles.

Parkinsonism: Syndrome characterized by tremor, rigidity, and bradykinesia.

Tic: Sudden, repetitive, non-rhythmic, stereotyped motor movement of vocalization involving discrete muscle groups, often seen in Tourette’s syndrome.

Tremor: Involuntary, rhythmic, alternating movement of one of more body parts, often seen in essential tremor, Parkinson’s disease, and alcohol withdrawal.

Hemiballismus: Repetitive, but constantly varying, large amplitude involuntary movements of the proximal parts of the limbs, often seen in stroke and traumatic brain injury.

Stereotypies: Repetitive, simple movements that can be voluntarily suppressed, often seen in autism and intellectual disability.

It is important to consider the underlying conditions and factors that may contribute to movement disorders in order to properly diagnose and treat these conditions.

SUDEP, of sudden unexpected death in epilepsy, is a condition where patients with epilepsy die suddenly and unexpectedly without any apparent cause. It is estimated to be responsible for 20-30% of deaths in epilepsy patients. The condition is more common in adults than in children, affecting 1 in 1,000 adults with epilepsy per year. The main risk factor for SUDEP is having active generalised tonic clonic seizures (GTCS), and better control of these seizures through improved compliance can reduce the risk of SUDEP. Other risk factors include nocturnal seizures, lamotrigine, never having been treated with an antiepileptic drug, intellectual disability, and male sex. However, the evidence for these factors is considered low. Autopsy findings in SUDEP cases do not reveal any specific cause of death, but obstruction of the airways and cardiorespiratory events such as arrhythmia are thought to be possible mechanisms.

Vaillant categorized defenses into four levels of maturity, starting from the most severe psychotic level, followed by immature, neurotic, and finally, mature defenses.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting. The CAGE is a well-known 4 question screening tool, but recent research has questioned its value. Other tools include SASQ (Single alcohol screening questionnaire), PAT (Paddington Alcohol Test), MAST (Michigan Alcoholism Screening Test), and RAPS4 (Rapid Alcohol Problem Screen 4). These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

Types of Tremor

Essential Tremor

Otherwise known as benign essential tremor, this is the most common type of tremor. It is not associated with any underlying pathology. It usually begins in the 40’s, affects mainly the hands, and is slowly progressive. It tends to worsen with heightened emotion. It usually presents with unilateral upper limb involvement then progresses to both limbs.

Parkinsonian Tremor

This tremor is associated with Parkinson’s disease. It is classically described as ‘pill rolling’ due to the characteristic appearance of the fingers.

Cerebellar Tremor

Otherwise known as an intention tremor. This is a slow, coarse tremor which gets worse with purposeful movement. This is seen in lithium toxicity (note that the tremor seen as a side effect of long term lithium is fine and classed as physiological).

Psychogenic Tremor

Also known as a hysterical tremor. This type of tremor tends to appear and disappear suddenly and is hard to characterise due to its changeable nature. It tends to improve with distraction.

Physiologic Tremor

This is a very-low-amplitude fine tremor that is barely visible to the naked eye. It is present in every normal person while maintaining a posture of movement. It becomes enhanced and visible in many conditions such as anxiety, hyperthyroidism, alcohol withdrawal, and as drug induced side effects.

It is useful to have a basic idea about the frequencies of different types of tremor.

Type of Tremor Frequency

Intention 2-3Hz

Parkinsonian 5Hz

Essential 7Hz

Physiological 10Hz

Psychogenic variable

The acronym YMRS stands for the Young Mania Rating Scale.

In psychiatry, various questionnaires and interviews are used to assess different conditions and areas. It is important for candidates to know whether certain assessment tools are self-rated of require clinical assistance. The table provided by the college lists some of the commonly used assessment tools and indicates whether they are self-rated of clinician-rated. For example, the HAMD and MADRS are clinician-rated scales used to assess the severity of depression, while the GDS is a self-rated scale used to screen for depression in the elderly. The YMRS is a clinician-rated scale used to assess the severity of mania in patients with bipolar disorder, while the Y-BOCS is used to measure both the severity of OCD and the response to treatment. The GAF provides a single measure of global functioning, while the CGI requires the clinician to rate the severity of the patient’s illness at the time of assessment. The CAMDEX is a tool developed to assist in the early diagnosis and measurement of dementia in the elderly.

Epilepsy: An Overview

Epilepsy is a condition that is diagnosed when a person experiences at least two unprovoked seizures that occur more than 24 hours apart. In the UK, the prevalence of epilepsy is 5-10 cases per 1000. Seizure types are categorized as focal onset of generalized onset. Focal seizures only involve a localized part of the brain, while generalized seizures involve the whole of both hemispheres. Temporal lobe epilepsy is the most common type of focal epilepsy, accounting for 60-70% of cases.

In 60% of people with epilepsy, there is no identifiable cause. Approximately 70% of people with epilepsy achieve remission, meaning they have no seizures for 5 years on of off treatment. of those with convulsive seizures, 2/3 have focal epilepsies and secondary generalized seizures, while the other 1/3 have generalized tonic-clonic seizures.

The National Institute for Health and Care Excellence (NICE) recommends treatment with antiepileptic drugs (AEDs) after a second epileptic seizure. For newly diagnosed focal seizures, carbamazepine of lamotrigine are recommended as first-line treatment. Levetiracetam, oxcarbazepine, of sodium valproate may be offered if carbamazepine and lamotrigine are unsuitable of not tolerated. For newly diagnosed generalized tonic-clonic seizures, sodium valproate is recommended as first-line treatment, with lamotrigine as an alternative if sodium valproate is unsuitable. For absence seizures, ethosuximide of sodium valproate are recommended as first-line treatment. For myoclonic seizures, sodium valproate is recommended as first-line treatment, and for tonic of atonic seizures, sodium valproate is also recommended as first-line treatment.

Lilliputian hallucinations are commonly observed in conditions caused by organic factors, such as withdrawal and intoxication.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

As individuals drift off to sleep, they may encounter hypnagogic hallucinations, which are characterized by sensory phenomena. These can vary from faint sensations to intense hallucinations. It is important to note that these occurrences are a natural part of the sleep cycle.

The tools mentioned are used for screening and diagnosing personality disorders. The SAPAS is an interview method that focuses on 8 areas and takes 2 minutes to complete. The FFMRF is self-reported and consists of 30 items rated 1-5 for each item. The IPDE is a semistructured clinical interview compatible with the ICD and DSM and includes both a patient questionnaire and an interview. The PDQ-R is self-reported and consists of 100 true/false questions based on DSM-IV criteria. The IPDS is an interview method that consists of 11 criteria and takes less than 5 minutes. The IIP-PD is self-reported and contains 127 items rated 0-4.

Types of Delusions

Delusions come in many different forms. It is important to familiarize oneself with these types as they may be tested in an exam. Some of the most common types of delusions include:

– Folie a deux: a shared delusion between two or more people
– Grandiose: belief that one has special powers, beliefs, of purpose
– Hypochondriacal: belief that something is physically wrong with the patient
– Ekbom’s syndrome: belief that one has been infested with insects
– Othello syndrome: belief that a sexual partner is cheating on them
– Capgras delusion: belief that a person close to them has been replaced by a double
– Fregoli delusion: patient identifies a familiar person (usually suspected to be a persecutor) in other people they meet
– Syndrome of subjective doubles: belief that doubles of him/her exist
– Lycanthropy: belief that one has been transformed into an animal
– De Clérambault’s syndrome: false belief that a person is in love with them
– Cotard’s syndrome/nihilistic delusions: belief that they are dead of do not exist
– Referential: belief that others/TV/radio are speaking directly to of about the patient
– Delusional perception: belief that a normal percept (product of perception) has a special meaning
– Pseudocyesis: a condition whereby a woman believes herself to be pregnant when she is not. Objective signs accompany the belief such as abdominal enlargement, menstrual disturbance, apparent foetal movements, nausea, breast changes, and labour pains.

Remembering these types of delusions can be helpful in understanding and diagnosing patients with delusional disorders.

Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

The SASQ is a screening questionnaire that consists of a single question asking about the last time an individual had more than a certain number of alcoholic drinks in one day (8 for men and 6 for women). If the response indicates that this occurred within the past 3 months, it suggests that the individual may be engaging in harmful of hazardous drinking.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems. One such tool is the AUDIT (Alcohol Use Disorders Identification Test), which consists of 10 questions and covers harmful use, hazardous use, and dependence. Another tool is the FAST (Fast Alcohol Screening Test), which has just 4 questions and was developed for use in a busy medical setting. The CAGE is a well-known 4 question screening tool, but recent research has questioned its value.

These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

The total score of E3 V5 M6 is 14.

The Glasgow Coma Scale is used to assess the depth of coma and impaired consciousness. Scores range from 3 to 15, with impaired consciousness rated as mild, moderate, of severe. The scale assesses eye opening response, verbal response, and motor response, with specific criteria for scoring each behavior. The final score is a combination of these three scores.
Scoring Guide;

4 Spontaneous opening
3 Opens to verbal stimuli
2 Opens to pain
1 No response

6 Obeys commands
5 Purposeful movement to painful stimuli
4 Withdraws in response to pain
3 Flexion in response to pain (decorticate posturing)
2 Extension in response to pain (decerebrate posturing)
1 No response

Neologism pertains to the creation of novel terms, while paraphasia involves the replacement of one word with another, such as saying orange instead of banana. Asyndesis, on the other hand, refers to a breakdown in the distinction between different concepts.

Formal Thought Disorders

In formal thought disorders, changes in the speed, coherence, and cogency of thought can be observed from a patient’s speech. These disorders can also be self-reported and may be accompanied by enhanced use of nonverbal language. One possible indication is a lack of an adequate connection between two consecutive thoughts, which is called ‘asyndesis’.

There are several types of formal thought disorders, including inhibited thinking, retarded thinking, circumstantial thinking, restricted thinking, perseverative thinking, rumination, pressured thinking, flight of ideas, tangential thinking, thought blocking, disruption of thought, incoherence/derailment, and neologisms.

Inhibited thinking is about the subjective experience of the patient, who may feel that their thinking process is slowed down of blocked by an inner wall of resistance. Retarded thinking, on the other hand, is about the observed quality of thought as inferred through speech, where the flow of thought processes is slowed down and sluggish.

Circumstantial thinking refers to an inability to separate the essential from the unessential during a conversation without rendering the conversation incoherent. Restricted thinking involves a limited range of thought content, fixation on one particular topic of a small number of topics only, and a stereotyped pattern of thinking.

Perseverative thinking is characterized by the persistent repetition of previously used words, phrases, of details to the point where they become meaningless in the context of the current stage of the interview. Rumination is the endless mental preoccupation with, of excessive concern over, mostly unpleasant thoughts.

Pressured thinking, also known as crowding of thought, is when the patient feels helplessly exposed to the pressures of floods of different ideas of thoughts. Flight of ideas involves an increasing multitude of thoughts and ideas which are no longer firmly guided by clear goal-directed thinking.

Tangential thinking occurs when the patient appears to understand the contents of the questions addressed to them but provides answers which are completely out of context. Thought blocking of disruption of thought refers to sudden disruption of an otherwise normal flow of thought of speech for no obvious reason.

Incoherence of derailment is when the interviewer is unable to establish sensible connections between the patient’s thinking and verbal output, which is sometimes also called derailment. Neologisms involve the formation of new words of usage of words which disregard normal conventions and are generally not easily understandable.

The feeling of insects crawling on the skin, also known as tactile hallucination, is referred to as formication. This symptom has been extensively studied and can be caused by various factors.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

Assessment and Management of Obesity

Obesity is a condition that can increase the risk of various health problems, including type 2 diabetes, coronary heart disease, some types of cancer, and stroke. The body mass index (BMI) is a commonly used tool to assess obesity, calculated by dividing a person’s weight in kilograms by their height in meters squared. For adults over 20 years old, BMI falls into one of the following categories: underweight, normal of healthy weight, pre-obesity/overweight, obesity class I, obesity class II, and obesity class III.

Waist circumference can also be used in combination with BMI to guide interventions. Diet and exercise are the main interventions up to a BMI of 35, unless there are comorbidities such as type 2 diabetes, hypertension, cardiovascular disease, osteoarthritis, dyslipidemia, and sleep apnea. Physical activity recommendations suggest that adults should accumulate at least 150 minutes of moderate intensity activity of 75 minutes of vigorous intensity activity per week. Dietary recommendations suggest diets that have a 600 kcal/day deficit.

Pharmacological options such as Orlistat of Liraglutide may be considered for those with a BMI of 30 kg/m2 of more, of 28 if associated risk factors. Surgical options such as bariatric surgery may be considered for those with a BMI of 40 kg/m2 of more, of between 35 kg/m2 and 40 kg/m2 with other significant diseases that could be improved with weight loss.

The delusional psychopathology is a secondary factor that can lead to delusions, while the other examples are considered primary delusions. It’s important to note that delusional mood is distinct from the mood disorder associated with depression, as it refers to a subtle sense of paranoia of unusual feeling that may precede the development of delusional beliefs.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

In this situation, it is more appropriate to use the defense mechanism of reaction formation instead of sublimation. Sublimation involves redirecting an impulse into a positive outlet, but since the individual in question has a negative behavior of heavy drinking, it would not be effective. On the other hand, reaction formation involves expressing the opposite of the true impulse, which would be more suitable. It is important to note that sublimation and reaction formation do have some similarities, with sublimation being a more advanced version of reaction formation.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Culture bound illnesses are psychiatric conditions that are specific to one particular culture. There are many different types of culture bound illnesses, including Amok, Shenjing shuairuo, Ataque de nervios, Bilis, colera, Bouffee delirante, Brain fag, Dhat, Falling-out, blacking out, Ghost sickness, Hwa-byung, wool-hwa-byung, Koro, Latah, Locura, Mal de ojo, Nervios, Rootwork, Pibloktoq, Qi-gong psychotic reaction, Sangue dormido, Shen-k’uei, shenkui, Shin-byung, Taijin kyofusho, Spell, Susto, Zar, and Wendigo.

Some of the most commonly discussed culture bound illnesses include Amok, which is confined to males in the Philippines and Malaysia who experience blind, murderous violence after a real of imagined insult. Ataque de nervios is a condition that occurs in those of Latino descent and is characterized by intense emotional upset, shouting uncontrollably, aggression, dissociation, seizure-like episodes, and suicidal gestures. Brain fag is a form of psychological distress first identified in Nigerian students in the 1960s but reported more generally in the African diaspora. It consists of a variety of cognitive and sensory disturbances that occur during periods of intense intellectual activity. Koro is a condition that affects Chinese patients who believe that their penis is withdrawing inside their abdomen, resulting in panic and the belief that they will die. Taijin kyofusho is a Japanese culture bound illness characterized by anxiety about and avoidance of interpersonal situations due to the thought, feeling, of conviction that one’s appearance and actions in social interactions are inadequate of offensive to others. Finally, Wendigo is a culture bound illness that occurs in Native American tribes during severe winters and scarcity of food, characterized by a distaste for food that leads to anxiety and the belief that one is turning into a cannibalistic ice spirit.

It is important to differentiate between verbigeration and vorbeirden. Verbigeration involves the senseless repetition of words of phrases, while vorbeirden occurs when a patient comprehends a question but provides an obviously incorrect answer. This phenomenon is commonly observed in Ganser’s syndrome, a type of dissociative psychosis that often affects incarcerated individuals awaiting trial.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Understanding Wilson’s Disease: Causes, Symptoms, and Management

Wilson’s disease, also known as hepatolenticular degeneration, is a genetic disorder that affects copper storage in the body. This condition is caused by a defect in the ATP7B gene, which leads to the accumulation of copper in the liver and brain. The onset of symptoms usually occurs between the ages of 10 and 25, with liver disease being the most common presentation in children and neurological symptoms in young adults.

The excessive deposition of copper in the tissues can cause a range of symptoms, including hepatitis, cirrhosis, basal ganglia degeneration, speech and behavioral problems, asterixis, chorea, dementia, Kayser-Fleischer rings, sunflower cataract, renal tubular acidosis, haemolysis, and blue nails. Diagnosis is based on reduced serum ceruloplasmin, reduced serum copper, and increased 24-hour urinary copper excretion.

The traditional first-line treatment for Wilson’s disease is penicillamine, which chelates copper. Trientine hydrochloride is an alternative chelating agent that may become first-line treatment in the future. Tetrathiomolybdate is a newer agent that is currently under investigation.

In summary, Wilson’s disease is a genetic disorder that affects copper storage in the body, leading to a range of symptoms that can affect the liver, brain, and eyes. Early diagnosis and treatment are essential to prevent complications and improve outcomes.

The Global assessment of function scale was utilized in earlier editions of the DSM.

Assessing global functioning and impairment is now easier with the World Health Organization Disability Assessment Schedule 2 (WHODAS 2.0), a new tool offered by DSM-5. This patient self-report assessment tool evaluates a patient’s ability to perform activities in six domains of functioning over the previous 30 days, and uses these to calculate a score representing global disability. The six domains are understanding and communicating, mobility, self-care, social and interpersonal functioning, home, academic, and occupational functioning, and participation in family, social, and community activities. WHODAS 2.0 can be self-administered in around 5 minutes of administered through an interview in 20 minutes. Previous versions of the DSM used the Global Assessment of Functioning scale, which was a 100-point scale that measured a patient’s overall level of psychological, social, and occupational functioning. It was designed to be completed in under 3 minutes and was recorded under axis V of the DSM. A higher score corresponded to a higher level of functioning.

Anhedonia: The Inability to Experience Pleasure

Anhedonia is a negative symptom of schizophrenia that refers to the inability to experience pleasure of enjoyment from activities that are typically enjoyable. It is often described as a feeling of emotional emptiness of numbness. Anhedonia can have a significant impact on a person’s quality of life, as it can lead to social withdrawal and a lack of motivation to engage in activities that were once enjoyable. It is important for individuals with schizophrenia to receive proper treatment for anhedonia, as it can contribute to a worsening of other symptoms and overall functioning. With appropriate treatment, individuals with schizophrenia can learn to manage anhedonia and improve their quality of life.

In psychiatry, various questionnaires and interviews are used to assess different conditions and areas. It is important for candidates to know whether certain assessment tools are self-rated of require clinical assistance. The table provided by the college lists some of the commonly used assessment tools and indicates whether they are self-rated of clinician-rated. For example, the HAMD and MADRS are clinician-rated scales used to assess the severity of depression, while the GDS is a self-rated scale used to screen for depression in the elderly. The YMRS is a clinician-rated scale used to assess the severity of mania in patients with bipolar disorder, while the Y-BOCS is used to measure both the severity of OCD and the response to treatment. The GAF provides a single measure of global functioning, while the CGI requires the clinician to rate the severity of the patient’s illness at the time of assessment. The CAMDEX is a tool developed to assist in the early diagnosis and measurement of dementia in the elderly.

Alcohol screening tools are available to assist in the diagnosis of alcohol problems.

These tools can help identify hazardous of harmful alcohol consumption and alcohol dependence.

The frontal assessment battery does not include personality and calculation (attention) despite them being functions of the frontal lobe.

The Frontal Assessment Battery (FAB) is a quick and easy bedside test used to detect the dysexecutive syndrome. It consists of six subsets, including conceptualization, mental flexibility, motor programming, conflicting instructions, go-no go (inhibitory control), and prehension behavior. The test assesses a patient’s ability to perform tasks such as abstract reasoning, verbal fluency, and motor skills. The FAB can be completed in just a few minutes and is a useful tool for clinicians in evaluating patients with suspected executive dysfunction.

Mental State Exam: Appearance

The appearance of a patient can provide valuable clues to an underlying disorder. It is important to note that the following examples are not always present, but they can be helpful for educational purposes.

Individuals experiencing hypomania or mania may tend to wear bright and colorful clothing and may apply unusual of garish makeup. On the other hand, unfashionable and mismatched clothing may indicate schizoid personality traits of autistic spectrum disorders.

An excessively tidy appearance may suggest an obsessional personality. It is important to consider these cues in conjunction with other aspects of the mental state exam to arrive at an accurate diagnosis. Proper observation and interpretation of a patient’s appearance can aid in the development of an effective treatment plan.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Classification of Diseases: A Brief Overview

A scientific classification system should have standardized names, clear operational criteria, and a multiaxial arrangement for citing important attributes. The International Classification of Diseases (ICD) has been the main nosologic system for identifying human ailments for the past century. It has a well-organized and widely accepted nomenclature, but lacks operational criteria and an appropriate multiaxial pattern. The ICD-10 is available in major languages and classifies psychiatric conditions under Mental and behavioural disorders in Chapter V. However, it does not include social consequences of the disorder, which is included in the DSM IV under Axis 4 (Psychosocial and Environmental Problems). Neurasthenia is classified under Other neurotic disorders (F48.0) in the ICD-10. Overall, classification of diseases is a system of categories to which morbid entities are assigned according to established criteria.

The Brief Psychiatric Rating Scale assesses the level of cooperation with the interview, utilizing a combination of self-report and clinical observation. Due to its reliance on these methods, it cannot be conducted via telephone.

Brief Psychiatric Rating Scale: An Instrument for Evaluating Psychopathology in Psychiatric Patients

The Brief Psychiatric Rating Scale (BPRS) is a widely used tool for assessing psychopathology in psychiatric patients. It was developed in the 1960s by Overall and Gorham, using factor analysis, to evaluate the severity of schizophrenic states and provide clinicians with a quick way to assess patient change. Initially, the BPRS consisted of 16 items, but two more items were added to create the standard 18-item version. Later, an expanded 24-item version was introduced to measure additional aspects of schizophrenia, such as bizarre behavior, self-neglect, suicidality, elevated mood, motor hyperactivity, and distractibility.

The BPRS is rated by a clinician, who assesses each item on a 7-point scale of severity. Higher scores indicate greater severity of symptoms. The assessment relies on a combination of self-report and observation. Several variables are rated based on observation, while the rest are assessed through a short interview. The total score severity, using the 18-item version, has been estimated as mildly ill (31), moderately ill (41), and markedly ill (53). The administration of the BPRS can take 10-40 minutes, and versions have been validated for use in both children and older adults. As it is clinician-administered, the BPRS does not require patients to be able to read of write.

Altered Perceptual Experiences

Disorders of perception can be categorized into sensory distortions and sensory deceptions. Sensory distortions involve changes in the intensity, spatial form, of quality of a perception. Examples include hyperaesthesia, hyperacusis, and micropsia. Sensory deceptions, on the other hand, involve new perceptions that are not based on any external stimulus. These include illusions and hallucinations.

Illusions are altered perceptions of a stimulus, while hallucinations are perceptions in the absence of a stimulus. Completion illusions, affect illusions, and pareidolic illusions are examples of illusions. Auditory, visual, gustatory, olfactory, and tactile hallucinations are different types of hallucinations. Pseudohallucinations are involuntary and vivid sensory experiences that are interpreted in a non-morbid way. They are different from true hallucinations in that the individual is able to recognize that the experience is an internally generated event.

Understanding the different types of altered perceptual experiences is important in the diagnosis and treatment of various mental health conditions.

Gillick Competency and Fraser Guidelines

Gillick competency and Fraser guidelines refer to a legal case which looked specifically at whether doctors should be able to give contraceptive advice of treatment to under 16-year-olds without parental consent. But since then, they have been more widely used to help assess whether a child has the maturity to make their own decisions and to understand the implications of those decisions.

In 1982, Mrs Victoria Gillick took her local health authority (West Norfolk and Wisbech Area Health Authority) and the Department of Health and Social Security to court in an attempt to stop doctors from giving contraceptive advice of treatment to under 16-year-olds without parental consent.

The case went to the High Court where Mr Justice Woolf dismissed Mrs Gillick’s claims. The Court of Appeal reversed this decision, but in 1985 it went to the House of Lords and the Law Lords (Lord Scarman, Lord Fraser and Lord Bridge) ruled in favour of the original judgement delivered by Mr Justice Woolf.

The Fraser Guidelines were laid down by Lord Fraser in the House of Lords’ case and state that it is lawful for doctors to provide contraceptive advice and treatment without parental consent providing that they are satisfied that:

– The young person will understand the professional’s advice
– The young person cannot be persuaded to inform their parents
– The young person is likely to begin, of to continue having, sexual intercourse with of without contraceptive treatment
– Unless the young person receives contraceptive treatment, their physical of mental health, of both, are likely to suffer
– The young person’s best interests require them to receive contraceptive advice of treatment with of without parental consent.

The Positive and Negative Syndrome Scale (PANSS) is a tool used to measure the severity of symptoms in patients with schizophrenia. The scale is divided into three categories: positive symptoms, negative symptoms, and general psychopathology symptoms. Each category has several items that are scored on a seven-point severity scale. The positive symptoms include delusions, hallucinations, and hyperactivity, while the negative symptoms include blunted affect and lack of spontaneity. The general psychopathology symptoms include anxiety, depression, and poor impulse control. The PANSS is a valuable tool for clinicians to assess the severity of symptoms in patients with schizophrenia and to monitor their progress over time.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

The implementation of operational criteria in diagnosis was a significant feature of DSM III, which was a response to the criticism of the previous versions of the DSM that relied heavily on psychodynamic concepts. This shift in approach is often praised for revitalizing the field of psychiatry.

Argyll Robertson Pupil: Accommodation Retained

The Argyll Robertson pupil is a notable topic in medical exams, as it is associated with tertiary syphilis, which is a crucial differential diagnosis for various psychiatric conditions like mood disorders, dementia, and psychosis. This type of pupil reacts poorly to light but normally to near stimuli, such as accommodation and convergence. They are typically small and irregular in shape, but they do not usually affect visual acuity. Mydriatic agents are not effective in dilating the Argyll Robertson pupil. Although this type of pupil is often considered pathognomonic of tertiary syphilis, it has also been observed in diabetes.

Based on the patient’s characteristics, it is possible that he has a pheochromocytoma.

Pheochromocytoma: Symptoms and Diagnosis

A pheochromocytoma is a tumor that secretes catecholamines and is usually found in the adrenal glands. Symptoms of this condition include hypertension, tachycardia, diaphoresis, livedo reticularis (mottled skin), postural hypotension, tachypnea, cold and clammy skin, severe headache, angina, palpitations, nausea, and vomiting.

To diagnose pheochromocytoma, doctors measure the levels of catecholamine products in the blood of urine. The metanephrines vanillylmandelic acid (VMA) and homovanillic acid (HVA) are the principal urinary metabolic products of epinephrine and norepinephrine. Healthy individuals excrete only small amounts of these substances.

Clock Drawing Test: A Screening Tool for Cognitive Dysfunction

The clock drawing test is a widely used screening tool for cognitive dysfunction. It involves asking the patient to draw a clock on a piece of paper, placing the numbers on the clock face and drawing the hands to indicate 10 minutes past 11. This simple task assesses a range of cognitive functions, including visuospatial ability, motor function, attention, and comprehension.

The test is quick and easy to administer, making it a useful tool for healthcare professionals to identify potential cognitive impairment in patients. The clock drawing test has been shown to be effective in detecting cognitive dysfunction in a variety of conditions, including Alzheimer’s and Parkinson’s disease.

The image below illustrates examples of clocks drawn correctly by healthy controls and those drawn by patients with Alzheimer’s and Parkinson’s disease. By comparing the drawings, healthcare professionals can quickly identify potential cognitive dysfunction and take appropriate action.

Techniques for Conducting Effective Interviews: Avoiding Leading Questions

One technique to avoid when conducting interviews is the use of leading questions. These are questions that suggest a particular answer of response, and can result in inaccurate of biased information. Instead, interviewers should strive to ask open-ended questions that allow the respondent to provide their own thoughts and opinions. By avoiding leading questions, interviewers can gather more reliable and unbiased information from their subjects. Additionally, interviewers should be mindful of their tone and body language, as these can also influence the responses they receive. Overall, effective interviewing requires careful preparation and a focus on creating a comfortable and open environment for the respondent.

Interview Techniques: Open and Closed Questions

When conducting an interview, it is important to use the appropriate types of questions. Open questions are designed to encourage a detailed response and can help to open up the conversation. In contrast, closed questions typically result in a yes of no answer and are useful for clarifying specific details. By using a combination of open and closed questions, interviewers can gather more information and gain a better understanding of the interviewee’s perspective. It is important to use these techniques effectively to ensure a successful interview.
