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 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.

The initial version of ICD-10 was released in 1992, while the first edition of ICD was published in 1855 to standardize the classification of causes of death. In 1948, ICD underwent a major revision and expanded from solely recording causes of death to encompass the International Lists of Diseases and Causes of Death, which was the 6th edition. DSM 4 was published in 1994, and there were no noteworthy alterations to the ICD/ DSM classifications in 1998.

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.

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.

What is the name of the current prime minister? This question is part of the Abbreviated Mental Test Score (AMTS).

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 Wechsler Adult Intelligence Scale (WAIS) is a widely used intelligence test in clinical settings, designed for individuals aged 16 to 90. Its counterpart for children is the Wechsler Intelligence Scale for Children (WISC). The current version of WAIS, WAIS-IV, consists of four index scores, each comprising several subsets. These are the Verbal Comprehension Index, Perceptual Reasoning Index, Working Memory Index, and Processing Speed Index. The results are presented as two scores: Full Scale IQ and General Ability Index. The average score is 100, with a standard deviation of 15. However, the test becomes less accurate at the extremes of IQ (70-130). About 3% of people score below 70, which is the general cut-off for a significant learning disability.

Rapid Risk Assessment for Sex Offence Recidivism (RRASOR)

The Rapid Risk Assessment for Sex Offence Recidivism (RRASOR) is a well-known actuarial tool that is used to predict the likelihood of sex offence recidivism. It comprises of four items that have been proven to have predictive accuracy for sex offence recidivism. These items include the number of past sex offence convictions of charges, the age of the offender being less than 25, the offender being unrelated to the victim, and the gender of the victim.

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.

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

Gedankenlautwerden pertains to thoughts that can be heard.

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.

Prolixity is a minor form of flight of ideas that can occur during hypomania. It is characterized by a decrease in clang and verbal associations, and a more focused direction of thought. The speed of thought is also not as rapid as in other forms of flight of ideas.

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 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.

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.

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.

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.

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 man’s longing for his girlfriend and the traveller’s thirst create affect illusions, distorting their perceptions. The woman who hears her mother when she sees the door open experiences a reflex hallucination, while the man who hears his wife’s voice describing something outside of his surroundings experiences an extracampine hallucination.

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.

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 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.

– 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.

The Beck’s depression inventory consists of 21 questions with a maximum score of 63. Each question is scored from 0 to 3 and is used to evaluate the severity of depression. It is a self-rated assessment that covers the two weeks leading up to the evaluation.

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.

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.

– 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.

The only primary delusion listed is delusional atmosphere, as it pertains to the form of the delusion. The other delusions mentioned are related to the content of the delusion and therefore cannot be classified as primary delusions.

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.

Both hyperthyroidism and hypothyroidism can lead to the development of pretibial myxoedema, while hyporeflexia is typically only observed in cases of hypothyroidism.

Thyroid Examination Findings

Hypothyroidism:

– Weight gain (with decreased appetite)
– Intolerance to cold
– Lethargy
– Constipation
– Menstrual disturbances
– Decreased perspiration

Exam findings:

– Hair loss
– Bradycardia
– Periorbital puffiness and dry skin
– Coarse, brittle, straw-like hair
– Myxoedema
– Hyporeflexia

Hyperthyroidism:

– Weight loss (with increased appetite)
– Intolerance to heat
– Palpitations
– Menstrual disturbances

Exam findings:

– Hair loss
– Tachycardia
– Warm, moist, and smooth skin
– Tremor
– Brisk reflexes

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.

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.

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.

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.

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.

Individuals with histrionic personality disorder are commonly characterized as having superficial and unstable emotions.

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.

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.

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.

– 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.

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.

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.

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%.

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.

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 DSM-III previously utilized the term passive-aggressive personality disorder.

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.

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.

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.

Understanding the Placebo Effect

In general, a placebo is an inert substance that has no pharmacological activity but looks, smells, and tastes like the active drug it is compared to. The placebo effect is the observable improvement seen when a patient takes a placebo, which results from patient-related factors such as expectations rather than the placebo itself. Negative effects due to patient-related factors are termed the nocebo effect.

Active placebos are treatments with chemical activity that mimic the side effects of the drug being tested in a clinical trial. They are used to prevent unblinding of the drug versus the placebo control group. Placebos need not always be pharmacological and can be procedural, such as sham electroconvulsive therapy.

The placebo effect is influenced by factors such as the perceived strength of the treatment, the status of the treating professional, and the branding of the compound. The placebo response is greater in mild illness, and the response rate is increasing over time. Placebo response is usually short-lived, and repeated use can lead to a diminished effect, known as placebo sag.

It is difficult to separate placebo effects from spontaneous remission, and patients who enter clinical trials generally do so when acutely unwell, making it challenging to show treatment effects. Breaking the blind may influence the outcome, and the expectancy effect may explain why active placebos are more effective than inert placebos. Overall, understanding the placebo effect is crucial in clinical trials and personalized medicine.

Cotard’s syndrome is a condition where an individual has a false belief that they are deceased of do not exist.

Delusional Misidentification Syndrome

Delusional misidentification syndrome refers to a group of disorders where individuals believe that the identity of a person, object, of place has been altered of changed. There are several subtypes of this syndrome, including Capgras syndrome, Fregoli syndrome, intermetamorphosis, subjective doubles, reduplicative paramnesia, mirrored self, delusional companions, and clonal pluralisation of the self. Each subtype is characterised by a specific delusion, such as believing that a loved one has been replaced by an exact double of that a place has been duplicated. These delusions can have a significant impact on an individual’s daily life and require appropriate treatment.

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.

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.

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.

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.

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.

– 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.

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.

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.

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.

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.

ECG Changes Associated with Chlorpromazine

Chlorpromazine is a psychotropic medication that has been associated with various ECG changes. One of the most notable changes is repolarization changes, which can be seen as ST segment and T wave changes. Additionally, chlorpromazine has been linked to heart blocks, which can be detected by a prolonged PR interval.

Another significant ECG finding associated with chlorpromazine is QTc prolongation. This is a potentially dangerous condition that can lead to torsades de pointes, a type of ventricular tachycardia that can be life-threatening. Other medications that have been linked to QTc prolongation include a wide range of antipsychotics and antidepressants.

It is important to note that not all patients who take chlorpromazine will experience ECG changes. However, healthcare providers should be aware of the potential risks and monitor patients closely for any signs of cardiac abnormalities. If ECG changes are detected, the medication may need to be adjusted of discontinued to prevent further complications.

Eysenck’s classification system consisted of three dimensions: Psychoticism, Neuroticism, and Introversion-extraversion. Despite its theoretical appeal, it has not been widely utilized, possibly due to challenges in its practical application in clinical settings.

Some people believe that redirecting their sexual desires towards more constructive and advantageous outcomes is a form of sublimation.

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.

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.

Thought block is the cognitive equivalent of obstruction in motor function.

The man’s denial was evident as he refused to acknowledge the external reality that his legs had been amputated. On the other hand, if he tried to change the subject and only reluctantly accepted the truth when pressed, it would suggest that he was suppressing his emotions and thoughts about the amputation.

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.

Motivated forgetting refers to the intentional or unintentional act of suppressing or repressing distressing memories. Suppression is a conscious form of motivated forgetting, while repression is a subconscious form.

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.

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.

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.

Capgras syndrome is caused by a delusional belief rather than a hallucinatory perception.

Delusional Misidentification Syndrome

Delusional misidentification syndrome refers to a group of disorders where individuals believe that the identity of a person, object, of place has been altered of changed. There are several subtypes of this syndrome, including Capgras syndrome, Fregoli syndrome, intermetamorphosis, subjective doubles, reduplicative paramnesia, mirrored self, delusional companions, and clonal pluralisation of the self. Each subtype is characterised by a specific delusion, such as believing that a loved one has been replaced by an exact double of that a place has been duplicated. These delusions can have a significant impact on an individual’s daily life and require appropriate treatment.
