A 25-year-old male presents in clinic, insisting that you diagnose his colon issues. He describes experiencing vague sensations of incomplete stool passage and is worried that he may have a tumor causing obstruction. He reports regular bowel movements and denies any episodes of diarrhea or constipation. There is no history of blood in his stool, unintentional weight loss, or loss of appetite. He has no family history of cancer. After discussing your negative findings, he abruptly leaves the office, stating, You're just like the other four doctors I've seen, all incompetent and willing to let me die.
What is the most accurate description of his gastrointestinal (GI) symptoms?Your Answer: Hypochondriasis
Explanation:Understanding Hypochondriasis: A Case Study
A 21-year-old man is convinced that he has an occult GI malignancy, despite having no signs, symptoms, or family history of such a problem. He has seen three doctors who have told him otherwise, but he persists in his belief and is now doctor shopping by seeing four doctors for the same issue. This behavior is a classic sign of hypochondria.
Hypochondriasis is a condition where a person is excessively worried about having a serious illness, despite having no or minimal symptoms. The fear and anxiety associated with this condition can be debilitating and can interfere with a person’s daily life. In this case, the patient’s fixation on a particular disease is causing him distress and leading him to seek out multiple doctors for reassurance.
It is important to note that hypochondriasis is not the same as somatisation disorder, which refers to patients with a constellation of physical complaints that cannot be explained by a somatic process. While the patient in this case is fixated on a particular disease, he does not fit the criteria for somatisation.
It is also important to rule out other conditions, such as acute stress disorder or conversion disorder, which can present with similar symptoms. Acute stress disorder is an anxiety condition that is precipitated by an acute stressor and resolves within a month. Conversion disorder is a neurological deficit in the absence of a somatic cause and is usually preceded by a psychosocial stressor.
In conclusion, understanding hypochondriasis and its symptoms is crucial in providing appropriate care for patients who may be suffering from this condition. It is important to approach these patients with empathy and understanding, while also ruling out other potential conditions.

A 35-year-old male contacts his GP at 2PM to schedule his blood tests following a recent visit to his psychiatrist. The psychiatrist has raised his lithium dosage and requested that the GP arrange for lithium levels to be checked at the appropriate time after taking the medication. The patient took his first increased dose of lithium at 10AM (4 hours ago). In how many hours should the GP schedule the blood test to be taken?
Your Answer: 6 hours
Correct Answer: 8 hours
Explanation:Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.
Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

An 81-year-old man is transferred from a nursing home with a change in behaviour, insomnia and fever. Staff in the nursing home state that over the last five days, he has appeared confused and agitated and seems to be having visual hallucinations, as he has been talking and gesturing to people who are not present in the room. He has a past medical history of Lewy body dementia. On clinical examination, he is not orientated to time, place or person. He is mildly agitated. His blood pressure is 112/60 mmHg, pulse 96 bpm and temperature 38.2 °C. Urinalysis is positive for nitrites and leukocytes.
Which of the following management plans should be considered as initial treatment for delirium?Your Answer: Treat the underlying cause, ensure effective communication and reorientation, provide reassurance for people diagnosed with delirium, provide a suitable care environment
Explanation:Managing Delirium: Strategies for Treatment and Care Environment
Delirium is a serious condition that requires prompt identification and management of underlying causes. Effective communication and reorientation, as well as reassurance for the patient, are crucial in managing delirium. Involving family, friends, and carers can also be helpful. Providing a suitable care environment, such as a well-lit and quiet room with minimal stimulation, is important. If verbal and non-verbal de-escalation techniques are ineffective, short-term use of antipsychotic drugs like haloperidol or olanzapine may be necessary, but caution should be exercised, especially for patients with conditions like Parkinson’s disease or dementia with Lewy bodies. Frequent reorientation and monitoring in a dimly lit room may also be necessary in some cases. Overall, a comprehensive approach that addresses both the underlying causes and the patient’s immediate needs is essential in managing delirium.

A 26-year-old female patient visits her general practitioner with concerns about her interpersonal relationships both at work and in her personal life. She reveals that this has been a persistent issue since her teenage years. She finds it challenging to collaborate with others and identifies herself as a perfectionist. Additionally, she has been described by others as rigid. What personality disorder is indicated by these symptoms?
Your Answer: Schizoid personality disorder
Correct Answer: Obsessive-compulsive personality disorder
Explanation:Patients diagnosed with obsessive-compulsive personality disorder tend to have inflexible attitudes towards morals, ethics, and values, and are often hesitant to delegate tasks to others. They exhibit perfectionistic tendencies and adhere to strict protocols in their work. This disorder makes it challenging for them to collaborate with others and adapt to different ways of doing things.
Personality disorders are a set of personality traits that are maladaptive and interfere with normal functioning in life. It is estimated that around 1 in 20 people have a personality disorder, which are typically categorized into three clusters: Cluster A, which includes Odd or Eccentric disorders such as Paranoid, Schizoid, and Schizotypal; Cluster B, which includes Dramatic, Emotional, or Erratic disorders such as Antisocial, Borderline (Emotionally Unstable), Histrionic, and Narcissistic; and Cluster C, which includes Anxious and Fearful disorders such as Obsessive-Compulsive, Avoidant, and Dependent.
Paranoid individuals exhibit hypersensitivity and an unforgiving attitude when insulted, a reluctance to confide in others, and a preoccupation with conspiratorial beliefs and hidden meanings. Schizoid individuals show indifference to praise and criticism, a preference for solitary activities, and emotional coldness. Schizotypal individuals exhibit odd beliefs and magical thinking, unusual perceptual disturbances, and inappropriate affect. Antisocial individuals fail to conform to social norms, deceive others, and exhibit impulsiveness, irritability, and aggressiveness. Borderline individuals exhibit unstable interpersonal relationships, impulsivity, and affective instability. Histrionic individuals exhibit inappropriate sexual seductiveness, a need to be the center of attention, and self-dramatization. Narcissistic individuals exhibit a grandiose sense of self-importance, lack of empathy, and excessive need for admiration. Obsessive-compulsive individuals are occupied with details, rules, and organization to the point of hampering completion of tasks. Avoidant individuals avoid interpersonal contact due to fears of criticism or rejection, while dependent individuals have difficulty making decisions without excessive reassurance from others.
Personality disorders are difficult to treat, but a number of approaches have been shown to help patients, including psychological therapies such as dialectical behavior therapy and treatment of any coexisting psychiatric conditions.

You have been referred a 14-year-old girl who appears very upset by her parents’ ongoing divorce. She has begun to engage in self-injurious behaviour by banging her head against walls at times of stress. Her intelligence quotient (IQ) has been assessed by her school as 62.
With which of the following is this score most consistent?Your Answer: Moderate learning disability
Correct Answer: Mild learning disability
Explanation:Understanding Learning Disabilities: Levels of Intelligence Quotient (IQ)
Learning disabilities are diagnosed through a combination of intelligence testing and functional assessments. The intelligence quotient (IQ) level is used to determine the severity of the learning disability. A score of 70 is considered within the normal range, while a score between 50-69 indicates a mild learning disability. A score of 35-49 is classified as a moderate learning disability, and a score of 20-34 is considered a severe learning disability. Scores below 20 indicate a profound learning disability. It’s important to note that a score of 60 falls within the mild learning difficulty range, which is still considered a learning disability. Understanding IQ levels can help individuals and their families better understand and manage their learning disabilities.

A 38-year-old teacher has called for the pest controller for the third time in the past month. She is worried that her house is infested with rats and she frequently checks under the beds and around the property for any signs of the infestation. She mentions that she saw a therapist in her early twenties for obsessive hand washing and underwent a brief period of cognitive behavioural therapy.
Upon physical examination, there are no abnormalities found. However, upon further questioning, she admits to feeling compelled to check for rats and is constantly anxious about cleanliness.
What is the most probable diagnosis?Your Answer: Obsessive-compulsive disorder (OCD)
Explanation:Differentiating OCD from other mental health conditions
Obsessive-compulsive disorder (OCD) is characterized by repetitive cycles of ritualistic behavior. It is important to differentiate OCD from other mental health conditions such as schizophrenia, anxiety, bipolar disease, and depression. Cognitive behavioral therapy and exposure response prevention are the mainstays of therapy for OCD, along with medication. Features consistent with schizophrenia, anxiety, bipolar disease, and depression are absent in OCD. Understanding the differences between these conditions is crucial in providing appropriate treatment.

Question 7

You're on an acute take ward and you are asked to see a patient by your foundation doctor. The foundation doctor is concerned about this patient as he is uncertain of the next step in management and investigation.
The patient is a 46-year-old male who has been admitted with excess tearing. He has a past medical history of allergic rhinitis. He uses nasal saline rinses several times a day. His father recently died of lung cancer with brain metastases.
This patient has had extensive investigations in multiple other hospitals due to his concerns of a cancer diagnosis causing his excessively watery eyes. He has had three CT orbits in the last 12 months which have been reported as normal. On ophthalmic examination, he has some crusting and erythema of his lid margins, but it is a normal examination otherwise. The patient remains convinced that a cancer diagnosis still can't be excluded.
What is the reason for this patient's presentation?Your Answer: Somatoform disorder
Correct Answer: Illness anxiety disorder
Explanation:Illness anxiety disorder, also known as hypochondriasis, is characterized by a persistent belief that there is an underlying serious disease present, such as cancer. This can lead to recurrent visits to healthcare providers, even after a cause for the patient’s symptoms has been identified.
In this particular case, the patient’s symptoms have been attributed to external eye disorders such as ectropion and blepharitis, which can affect tear drainage and cause dry or watery eyes. However, the patient still expresses a fear that there may be an undiscovered underlying cause for their symptoms.
This fear is consistent with illness anxiety disorder, which is one of several psychological disorders that can lead to frequent healthcare visits. Another example is conversion disorder, which involves the loss of a function without a medical or structural cause. While patients may not be bothered by the symptoms themselves, they are often associated with previous distressing experiences and other mental health conditions.
Psychiatric Terms for Unexplained Symptoms
There are various psychiatric terms used to describe patients who exhibit symptoms for which no organic cause can be found. One such disorder is somatisation disorder, which involves the presence of multiple physical symptoms for at least two years, and the patient’s refusal to accept reassurance or negative test results. Another disorder is illness anxiety disorder, which is characterized by a persistent belief in the presence of an underlying serious disease, such as cancer, despite negative test results.
Conversion disorder is another condition that involves the loss of motor or sensory function, and the patient does not consciously feign the symptoms or seek material gain. Patients with this disorder may be indifferent to their apparent disorder, a phenomenon known as la belle indifference. Dissociative disorder, on the other hand, involves the process of ‘separating off’ certain memories from normal consciousness, and may manifest as amnesia, fugue, or stupor. Dissociative identity disorder (DID) is the most severe form of dissociative disorder and was previously known as multiple personality disorder.
Factitious disorder, also known as Munchausen’s syndrome, involves the intentional production of physical or psychological symptoms. Finally, malingering is the fraudulent simulation or exaggeration of symptoms with the intention of financial or other gain. Understanding these psychiatric terms can help healthcare professionals better diagnose and treat patients with unexplained symptoms.

Question 8
Correct

A 31-year-old woman comes to you with complaints of worsening low mood and uncontrollable behaviors. She reports feeling distressed and finds relief only by repeating a certain phrase in her mind. She has no significant medical history and is in good physical health.
What is the symptom being described in this case?Your Answer: Compulsion
Explanation:An obsession is an unwelcome and intrusive thought that causes discomfort. On the other hand, a compulsion is an irrational behavior that a person feels compelled to perform in order to alleviate the anxiety caused by the obsession.
Compulsions can be either mental or physical, such as repeatedly washing one’s hands or checking if a door is locked. In contrast, thought insertion is a symptom of schizophrenia where a person feels that their thoughts are not their own and have been inserted by someone else.
Intrusive thoughts are involuntary and unwelcome thoughts that can be experienced by anyone. However, if they become frequent and distressing, they can develop into obsessions, which are a more severe form of intrusive thoughts. Obsessions, when coupled with compulsions, are a defining feature of obsessive-compulsive disorder (OCD).
Lastly, thought withdrawal is another delusion found in schizophrenia where a person believes that their thoughts have been taken away by an external force.
Obsessive-compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions that can cause significant functional impairment and distress. Risk factors include family history, age, pregnancy/postnatal period, and history of abuse, bullying, or neglect. Treatment options include low-intensity psychological treatments, SSRIs, and more intensive CBT (including ERP). Severe cases should be referred to the secondary care mental health team for assessment and may require combined treatment with an SSRI and CBT or clomipramine as an alternative. ERP involves exposing the patient to an anxiety-provoking situation and stopping them from engaging in their usual safety behavior. Treatment with SSRIs should continue for at least 12 months to prevent relapse and allow time for improvement.

A 32-year-old man with a diagnosis of bipolar disorder is brought in by police under section 136 of the mental health act. His psychiatrist has recently adjusted his medication. He was found dancing in the middle of a busy street claiming to be the king of the world.
Upon assessment, he appears elated, his speech is rapid and he appears easily distracted. He believes he has been chosen by a higher power to save the world from destruction and hasn't slept for days as a result.
The patient is sectioned and admitted to the mental health ward.
What is the most appropriate course of action?Your Answer: Start lithium
Correct Answer: Stop sertraline and start olanzapine
Explanation:When managing mania or hypomania in patients who are taking antidepressants, it may be necessary to discontinue the use of the antidepressant and initiate treatment with antipsychotic medication.
Understanding Bipolar Disorder
Bipolar disorder is a mental health condition that is characterized by alternating periods of mania/hypomania and depression. It typically develops in the late teen years and has a lifetime prevalence of 2%. There are two recognized types of bipolar disorder: type I, which involves mania and depression, and type II, which involves hypomania and depression.
Mania and hypomania both refer to abnormally elevated mood or irritability, but mania is more severe and can include psychotic symptoms for 7 days or more. Hypomania, on the other hand, involves decreased or increased function for 4 days or more. The presence of psychotic symptoms suggests mania.
Management of bipolar disorder may involve psychological interventions specifically designed for the condition, as well as medication. Lithium is the mood stabilizer of choice, but valproate can also be used. Antipsychotic therapy, such as olanzapine or haloperidol, may be used to manage mania/hypomania, while fluoxetine is the antidepressant of choice for depression. It is important to address any co-morbidities, as there is an increased risk of diabetes, cardiovascular disease, and COPD in individuals with bipolar disorder.
If symptoms suggest hypomania, routine referral to the community mental health team (CMHT) is recommended. However, if there are features of mania or severe depression, an urgent referral to the CMHT should be made. Understanding bipolar disorder and its management is crucial for healthcare professionals to provide appropriate care and support for individuals with this condition.

A 29-year-old man presented to the hospital, accompanied by the police after having had a fight in a casino. The casino manager called the police when the man refused to leave after he had spent almost 24 hours gambling. The patient ran out of money and was harassing other clients, trying to borrow money from them and telling them that he will return it after he had won and invested the prize money. The patient has no known next of kin and refuses to engage with the attending doctor. He threatens to assault the medical staff and is eventually put under urgent mental health Section 4. A review of his medical notes reveals that the only medication on which he has been is lithium for a known psychiatric illness, but he has not been in touch with his general practitioner for the past two months.
What is the best course of action for managing this patient?Your Answer: Check the lithium levels and consider adding olanzapine
Explanation:Management of Bipolar Depression with Mania or Hypomania
According to the latest NICE guideline CG85, patients with bipolar depression presenting with mania or hypomania should have their lithium levels checked and consider adding an antipsychotic such as haloperidol, olanzapine, quetiapine or risperidone. Therefore, checking the lithium levels and considering adding olanzapine is the correct answer in this case.
Stopping lithium without checking the levels first is not recommended as it is a mood stabiliser and may be required for the patient. Starting haloperidol or risperidone without checking the lithium levels is also not recommended as the doctor must consider the patient’s lithium levels before adding an antipsychotic.

A 32-year-old woman has come to her doctor for a medication review. She was diagnosed with bipolar disorder 10 months ago and has been taking olanzapine 10 mg once daily and lithium carbonate 600mg twice daily. While her psychological symptoms have improved, she has been feeling more fatigued in the past few weeks. Additionally, she has noticed a decrease in appetite and has experienced bouts of constipation. What is the most probable cause of her symptoms?
Your Answer: Hypothyroidism due to lithium toxicity
Explanation:Chronic lithium toxicity is the leading cause of hypothyroidism, which is the most common endocrine disorder. The onset of this condition typically occurs within 6 to 18 months of starting lithium treatment, although the exact mechanism by which lithium inhibits thyroid hormone release is not well understood. While olanzapine does not cause hypothyroidism or hypercalcemia, lithium is not associated with hypoadrenalism. Although undertreatment of bipolar disorder can lead to a depressive episode, the patient in this case has experienced an improvement in mood and the emergence of new somatic symptoms, making hypothyroidism due to lithium toxicity a more probable diagnosis.
Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.
Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

A 27-year-old woman comes to the GP for a mental health check-up. She had previously sought help 9 months ago for a major depressive episode that was successfully treated with fluoxetine, which she has now discontinued. Presently, she reports feeling fantastic. She has only slept for 4 hours each night over the past 5 days and has been busy renovating her entire house while still managing to attend work, where her boss has commended her on her newfound confidence and productivity. You observe that she speaks rapidly and that her thoughts are occasionally difficult to follow. There are no indications of self-neglect. What is the probable diagnosis?
Your Answer: Type 2 bipolar affective disorder
Explanation:The distinction between type I and type II bipolar disorder lies in the presence of mania versus hypomania, respectively. Today, the patient exhibits symptoms of elated mood, decreased need for sleep, increased productivity, rapid speech, and flight of ideas, which are characteristic of mania. However, the absence of psychotic symptoms and the lack of impairment in functioning suggest a diagnosis of hypomania instead. Given the patient’s history of depression, her current presentation is consistent with bipolar affective disorder.

A 42-year-old man is brought to the Emergency Department by his friends. He holds a senior trading job in an investment bank and has a history of recurrent admissions following cocaine intoxication. They are worried because he recently sent a memo to everyone on the trading floor suggesting that he is now the lead, he has the mental capacity to beat anyone to a higher profit and he should be chairman of the group. In fact, he has been performing poorly and has missed recent performance targets.
Which of the following is the most likely diagnosis?Your Answer: Cocaine-induced delusional disorder
Explanation:Understanding the Psychological Effects of Cocaine Use
Cocaine use can lead to a range of psychological and psychiatric problems, including delusional disorder. This disorder is characterized by grandiose ideas concerning one’s social standing or intellectual ability, which are far in excess of reality. Cocaine-induced hallucinations are also common, particularly of the auditory or tactile variety.
While some may mistake these symptoms for schizophrenia or a manic episode of bipolar disorder, it is important to consider the individual’s history of cocaine use. Cocaine intoxication can cause anxiety, agitation, euphoria, enlarged pupils, and palpitations, while severe intoxication can lead to delirium, hyperactivity, hyperthermia, and psychosis. Cocaine withdrawal, on the other hand, can cause fatigue, agitation, vivid and unpleasant dreams, increased appetite, and psychomotor retardation.
Overall, it is crucial to understand the potential psychological effects of cocaine use and seek appropriate treatment if necessary.

A 20-year-old female has presented to the emergency department with a history of diarrhoea for the past week. She denies any blood in her stool or exposure to infectious agents. The patient reports feeling more fatigued and sleeping more than usual.
The patient has a history of depression and was prescribed sertraline. However, she stopped taking the medication two weeks ago as she felt she no longer needed it. Her mental state is currently stable and euthymic.
During the general examination, the patient's pupils are noted to be bilaterally dilated, which was also observed during her childhood. What is the most likely feature in this patient that is a result of discontinuing her medication?Your Answer: Mydriasis
Correct Answer: Diarrhoea
Explanation:Diarrhoea is the correct answer as the patient’s protracted diarrhoea, abdominal cramping, and vomiting are common symptoms of SSRI discontinuation syndrome, which she stopped taking two weeks prior to her presentation. Occam’s razor suggests that this syndrome is more likely than inflammatory bowel disease or gastroenteritis, given the timeline and normal blood results. Euthymia is incorrect as SSRI discontinuation syndrome more commonly results in mood changes, and hypersomnia is incorrect as insomnia is more commonly seen. Generalised weakness is also incorrect as it is likely due to diarrhoea, and there are no focal neurology symptoms to suggest otherwise. Additionally, SSRI discontinuation syndrome can result in paraesthesias rather than a general feeling of fatigue and weakness.
Selective serotonin reuptake inhibitors (SSRIs) are commonly used as the first-line treatment for depression. Citalopram and fluoxetine are the preferred SSRIs, while sertraline is recommended for patients who have had a myocardial infarction. However, caution should be exercised when prescribing SSRIs to children and adolescents. Gastrointestinal symptoms are the most common side-effect, and patients taking SSRIs are at an increased risk of gastrointestinal bleeding. Patients should also be aware of the possibility of increased anxiety and agitation after starting a SSRI. Fluoxetine and paroxetine have a higher propensity for drug interactions.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a warning regarding the use of citalopram due to its association with dose-dependent QT interval prolongation. As a result, citalopram and escitalopram should not be used in patients with congenital long QT syndrome, known pre-existing QT interval prolongation, or in combination with other medicines that prolong the QT interval. The maximum daily dose of citalopram is now 40 mg for adults, 20 mg for patients older than 65 years, and 20 mg for those with hepatic impairment.
When initiating antidepressant therapy, patients should be reviewed by a doctor after 2 weeks. Patients under the age of 25 years or at an increased risk of suicide should be reviewed after 1 week. If a patient responds well to antidepressant therapy, they should continue treatment for at least 6 months after remission to reduce the risk of relapse. When stopping a SSRI, the dose should be gradually reduced over a 4 week period, except for fluoxetine. Paroxetine has a higher incidence of discontinuation symptoms, including mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.
When considering the use of SSRIs during pregnancy, the benefits and risks should be weighed. Use during the first trimester may increase the risk of congenital heart defects, while use during the third trimester can result in persistent pulmonary hypertension of the newborn. Paroxetine has an increased risk of congenital malformations, particularly in the first trimester.

A 28-year-old man is brought to the emergency department by security after attempting to enter a music studio. He claims to have a close relationship with a famous musician and just wanted to see him. Despite never having met the musician, he has sent numerous letters and messages. He reports feeling great. He denies any hallucinations. He appears normal and speaks clearly.
What is the probable diagnosis based on his behavior?Your Answer: Delusional disorder
Explanation:Erotomania, also known as De Clerambault’s syndrome, is a type of delusional disorder where the individual believes that a famous person is in love with them. This belief is not accompanied by any other symptoms of psychosis or mood disturbances. Other types of delusions include grandiose and persecutory delusions. Schizotypal personality disorder is characterized by odd beliefs and behaviors, but not to the extent of delusional conviction. Narcissistic personality disorder involves a long-standing pattern of inflated self-importance, a need for excessive admiration, and a lack of empathy. Histrionic personality disorder is characterized by excessive attention-seeking behavior. Bipolar disorder involves periods of both mania and depression.
De Clerambault’s Syndrome: A Delusional Belief in Famous Love
De Clerambault’s syndrome, also known as erotomania, is a type of paranoid delusion that has a romantic aspect. Typically, the patient is a single woman who firmly believes that a well-known person is in love with her. This condition is characterized by a persistent and irrational belief that the famous person is sending secret messages or signals of love, even though there is no evidence to support this belief. The patient may engage in behaviors such as stalking, sending letters or gifts, or attempting to contact the object of their affection. Despite repeated rejections or lack of response, the patient remains convinced of the love affair. This syndrome can be distressing for both the patient and the object of their delusion, and it often requires psychiatric treatment.

A 22-year old woman comes to see her GP, seeking medication for opioid withdrawal. She explains that she has been using heroin for the past six months since losing her job as a store manager. She informs the GP that she has decided to quit using heroin and has not taken any for the past three days. She reports experiencing severe withdrawal symptoms that have been affecting her daily life and asks if there is anything that can be prescribed to alleviate her symptoms.
What are the observable indications of opioid withdrawal?Your Answer: Pinpoint pupils, respiratory depression, pulmonary oedema
Correct Answer: Dilated pupils, yawning, rhinorrhoea, epiphora
Explanation:Identifying Objective Signs of Opioid Withdrawal and Intoxication
It is crucial to recognize objective signs of opioid withdrawal and intoxication to prevent fatal outcomes. In psychiatric settings, individuals may falsely claim withdrawal to obtain opioid medications. Objective signs of withdrawal include epiphora, rhinorrhoea, agitation, perspiration, piloerection, tachycardia, vomiting, shivering, yawning, and dilated pupils. Pinpoint pupils, yawning, and galactorrhoea are indicative of opiate intoxication. Respiratory depression is a feature of opioid intoxication, along with pinpoint pupils and bradycardia. Opioid intoxication can also cause pulmonary oedema, stupor, pallor, severe respiratory depression, and nausea. By recognizing these objective signs, healthcare professionals can accurately diagnose and treat opioid withdrawal and intoxication.

What is the most appropriate psychological approach for managing OCD in this case?Your Answer: Exposure response prevention (ERP) and cognitive behavioural therapy (CBT)
Explanation:Different Therapies for OCD: A Comparison
Obsessive-compulsive disorder (OCD) is a mental health condition that can be managed with various therapies. The most effective ones are exposure response prevention (ERP) and cognitive behavioural therapy (CBT), which are recommended by the National Institute for Health and Care Excellence (NICE). ERP involves exposing the patient to situations that trigger their compulsive behaviour while preventing them from acting on it. CBT, on the other hand, focuses on changing the patient’s thoughts, beliefs, and attitudes that contribute to their OCD.
Transactional analysis and psychoanalysis are not recommended for treating OCD as there is no evidence to support their use. Transactional analysis involves analysing social transactions to determine the ego state of the patient, while psychoanalysis involves exploring the unconscious to resolve underlying conflicts.
Counselling is also not appropriate for managing OCD as it is non-directive and does not provide specific coping skills.
Eye movement desensitisation and reprocessing (EMDR) is not effective for treating OCD either, as it is primarily used for post-traumatic stress disorder. EMDR combines rapid eye movement with cognitive tasks to help patients process traumatic experiences.
In conclusion, ERP and CBT are the most effective therapies for managing OCD, while other therapies such as transactional analysis, psychoanalysis, counselling, and EMDR are not recommended.

A 27-year-old woman visits her General Practitioner for a follow-up appointment after being diagnosed with depression. She is currently undergoing treatment with citalopram and has started a course of cognitive behavioural therapy (CBT).
What is used to assess the effectiveness of treatment in patients with depression?Your Answer: Patient Health Questionnaire (PHQ-9)
Explanation:Common Screening Tools Used in Primary Care
Primary care physicians often use various screening tools to assess their patients’ mental and physical health. Here are some of the most commonly used screening tools:
1. Patient Health Questionnaire-9 (PHQ-9): This tool is used to monitor the severity of depression and the response to treatment.
2. Mini-Mental State Examination (MMSE): This questionnaire is used to identify cognitive impairment and screen for dementia.
3. Alcohol Use Disorders Identification Test (AUDIT): This screening tool is used to identify signs of harmful drinking and dependence on alcohol.
4. Generalised Anxiety Disorder Questionnaire (GAD-7): This tool consists of seven questions and is used to screen for generalised anxiety disorder and measure the severity of symptoms.
5. Modified Single-Answer Screening Question (M-SASQ): This is a single question alcohol harm assessment tool designed for use in Emergency Departments. It identifies high-risk drinkers based on the frequency of consuming six or more units (if female) or eight or more units (if male) on a single occasion in the last year.
By using these screening tools, primary care physicians can identify potential health issues early on and provide appropriate treatment and care.

A 48-year-old woman with a history of manic-depressive psychosis, diagnosed at the age of 23, presents to her General Practitioner with polydipsia and polyuria. Current medication includes lithium and a steroid inhaler for bronchial asthma. Examination reveals a blood pressure (BP) of 110/75 mmHg, with a pulse of 80 bpm and regular. There are normal fasting sugar levels and there is no postural drop on standing.
What are the investigation findings most likely to help diagnose this condition?Your Answer: Low urine osmolality and high serum osmolality
Explanation:There are various medical conditions that can cause changes in urine and serum osmolality levels. Lithium is a common cause of acquired nephrogenic diabetes insipidus, which is characterized by low urine osmolality and high serum osmolality due to a deficiency in antidiuretic hormone secretion or poor kidney response to ADH. On the other hand, high blood sugar levels are associated with polyuria and polydipsia, which can be indicative of diabetes mellitus. Elevated serum calcium levels may be caused by hyperparathyroidism or vitamin D excess, which can also lead to polyuria and polydipsia. However, if the patient has a history of psychosis, psychogenic polydipsia may be the more likely cause. This condition is characterized by low urine and serum osmolality due to excessive water intake, often seen in middle-aged women with psychiatric comorbidities or after lesions in the hypothalamus affecting thirst centers. Syndrome of inappropriate antidiuretic hormone secretion (SIADH) is another disorder that can cause changes in urine and serum osmolality levels, characterized by high urine osmolality and low serum osmolality due to excessive ADH production.

A 56-year-old man is brought to the emergency department by ambulance, after being found confused by members of the public for the fifth time in the past month. Upon review, he tells you that he came here by bicycle after spending the afternoon with his friends doing shopping, and then later tells you he spent today in the pub with his new dog. He smells strongly of alcohol and you notice a near-empty bottle of unlabelled spirit with him.
On examination, he has an ataxic gait, dysdiadochokinesia and horizontal nystagmus.
When you go back later to see him, he has forgotten your previous interaction.
Which of the following explains his signs and symptoms?Your Answer: Wernicke's encephalopathy
Correct Answer: Korsakoff's syndrome
Explanation:The individual who arrived at the emergency department is exhibiting symptoms of Korsakoff’s syndrome, which is a result of Wernicke’s encephalopathy. These symptoms include cerebellar signs, eye signs, anterograde and retrograde amnesia, and confabulation. Additionally, the individual is carrying a bottle of alcohol and is inconsistent in their recollection of recent events.
Understanding Korsakoff’s Syndrome
Korsakoff’s syndrome is a memory disorder that is commonly observed in individuals who have a history of alcoholism. The condition is caused by a deficiency of thiamine, which leads to damage and bleeding in the mammillary bodies of the hypothalamus and the medial thalamus. Korsakoff’s syndrome often develops after untreated Wernicke’s encephalopathy.
The symptoms of Korsakoff’s syndrome include anterograde amnesia, which is the inability to form new memories, and retrograde amnesia. Individuals with this condition may also experience confabulation, which is the production of fabricated or distorted memories to fill gaps in their recollection.

A 50-year-old male with a past of alcohol addiction comes in with ataxia, confusion, and nystagmus. During the examination, a weakness in the sixth cranial nerve is observed.
What is the probable diagnosis?Your Answer: de Clerambault's syndrome
Correct Answer: Wernicke encephalopathy
Explanation:Neurological Disorders Associated with Alcoholism
Wernicke encephalopathy is a neurological disorder that occurs due to a deficiency in vitamin B-1, which is essential for carbohydrate metabolism. Alcohol consumption interferes with the absorption of thiamine, leading to a deficiency. Chronic liver disease also reduces the activation of thiamine pyrophosphate and the liver’s capacity to store thiamine. The symptoms of Wernicke encephalopathy include ataxia, confusion, and ocular abnormalities.
de Clerambault’s syndrome is a delusional disorder where the sufferer believes that someone of higher social or professional standing is in love with them. Delirium tremens is a condition that occurs due to alcohol withdrawal and is characterized by confusion, hallucinations, and autonomic disturbance. The symptoms of delirium tremens usually peak 48-72 hours after stopping alcohol.
Korsakoff’s psychosis is a type of dementia that occurs as a result of untreated Wernicke’s encephalopathy. The main symptom of Korsakoff’s psychosis is confabulation, where the sufferer creates false memories to fill gaps in their memory. These neurological disorders are commonly associated with alcoholism and can have severe consequences if left untreated.

You receive a call from the husband of a 50-year-old patient who is registered at your practice. The patient has a history of type 2 diabetes mellitus treated with metformin. According to her husband, for the past three days, she has been talking nonsensically and experiencing hallucinations. An Approved Mental Health Professional is contacted and heads to the patient's residence. Upon arrival, you encounter a disheveled and emaciated woman sitting on the pavement outside her home, threatening to physically harm you. What is the most appropriate course of action?
Your Answer: Check her blood sugar
Correct Answer: Call the police
Explanation:If the patient is exhibiting violent behavior in a public place, it is advisable to contact the police and have her taken to a secure location for a proper evaluation. It is important to note that Metformin does not lead to hypoglycemia.
Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.
Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.
Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.
Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.
Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.
Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.
Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

A 42-year-old male has arrived at the emergency department after experiencing a witnessed seizure. According to the witness, the seizure lasted around 10 minutes and the patient was drowsy for 15 minutes afterward. The patient is now alert and conversing with the medical staff. They have a history of schizophrenia and have reported several seizures since beginning a new medication five weeks ago. Which medication is the most probable cause of this incident?
Your Answer: Risperidone
Correct Answer: Clozapine
Explanation:Clozapine is the only atypical antipsychotic drug that reduces seizure threshold, increasing the likelihood of seizures. While effective, it has serious side effects such as agranulocytosis, neutropenia, reduced seizure threshold, and myocarditis. Aripiprazole has a favorable side effect profile and is less likely to cause hyperprolactinemia or other side effects. Olanzapine is known for causing dyslipidemia, weight gain, diabetes, and sedation, but may be prescribed to underweight patients who have trouble sleeping. Quetiapine is associated with weight gain, dyslipidemia, and postural hypotension.
Atypical antipsychotics are now recommended as the first-line treatment for patients with schizophrenia, as per the 2005 NICE guidelines. These medications have the advantage of significantly reducing extrapyramidal side-effects. However, they can also cause adverse effects such as weight gain, hyperprolactinaemia, and in the case of clozapine, agranulocytosis. The Medicines and Healthcare products Regulatory Agency has issued warnings about the increased risk of stroke and venous thromboembolism when antipsychotics are used in elderly patients. Examples of atypical antipsychotics include clozapine, olanzapine, risperidone, quetiapine, amisulpride, and aripiprazole.
Clozapine, one of the first atypical antipsychotics, carries a significant risk of agranulocytosis and requires full blood count monitoring during treatment. Therefore, it should only be used in patients who are resistant to other antipsychotic medication. The BNF recommends introducing clozapine if schizophrenia is not controlled despite the sequential use of two or more antipsychotic drugs, one of which should be a second-generation antipsychotic drug, each for at least 6-8 weeks. Adverse effects of clozapine include agranulocytosis, neutropaenia, reduced seizure threshold, constipation, myocarditis, and hypersalivation. Dose adjustment of clozapine may be necessary if smoking is started or stopped during treatment.

A 42-year-old man visits his doctor's office and reports that his partner of many years passed away recently. He shares that when he woke up this morning, he believed he was lying next to her and heard her voice calling his name. Despite knowing that this is impossible, it has caused him considerable anguish. He is concerned that he may be losing his mind. He has no other significant psychiatric history.
What is the probable diagnosis?Your Answer: Depression with psychosis
Correct Answer: Pseudohallucination
Explanation:Pseudohallucinations, which are characterized by the patient’s awareness that the voice or feeling is coming from their own mind, are not indicative of psychosis or serious psychiatric conditions. This makes schizophrenia and other psychotic options less likely, and there are no signs of schizoid personality disorder in the patient. Pseudohallucinations are often observed in individuals who have experienced bereavement.
Understanding Pseudohallucinations
Pseudohallucinations are false sensory perceptions that occur in the absence of external stimuli, but with the awareness that they are not real. While not officially recognized in the ICD 10 or DSM-5, there is a general consensus among specialists about their definition. Some argue that it is more helpful to view hallucinations on a spectrum, from mild sensory disturbances to full-blown hallucinations, to avoid misdiagnosis or mistreatment.
One example of a pseudohallucination is a hypnagogic hallucination, which occurs during the transition from wakefulness to sleep. These vivid auditory or visual experiences are fleeting and can happen to anyone. It is important to reassure patients that these experiences are normal and do not necessarily indicate the development of a mental illness.
Pseudohallucinations are particularly common in people who are grieving. Understanding the nature of these experiences can help healthcare professionals provide appropriate support and reassurance to those who may be struggling with them. By acknowledging the reality of pseudohallucinations and their potential impact on mental health, we can better equip ourselves to provide compassionate care to those who need it.

A 45-year-old woman presents to the Outpatient clinic with complaints of involuntary muscle movements of her tongue, fingers and trunk for the past 2 months. She was diagnosed with schizophrenia 10 years ago and has been on flupenthixol and then haloperidol, with good compliance. On examination, her temperature is 37.7 °C, blood pressure 115/80 mmHg and pulse 92 bpm. Her respiratory rate is 14 cycles/min. There is pronounced choreoathetoid movement of the hand and fingers.
What is the next line of management of this patient?Your Answer: Stop the haloperidol and start chlorpromazine
Correct Answer: Stop the haloperidol and start olanzapine
Explanation:Treatment options for extrapyramidal side-effects of anti-psychotic medication
Extrapyramidal side-effects are common with anti-psychotic medication, particularly with typical anti-psychotics such as haloperidol and chlorpromazine. Tardive dyskinesia is one such side-effect, which can be treated by switching to an atypical anti-psychotic medication like olanzapine. Acute dystonia, on the other hand, can be managed with anticholinergics. Decreasing the dose of haloperidol can help alleviate akathisia, or motor restlessness. Supportive therapy is not effective in treating extrapyramidal side-effects. It is important to monitor patients for these side-effects and adjust medication accordingly to ensure optimal treatment outcomes.

A 30-year-old man visits his doctor six weeks after being diagnosed with generalised anxiety disorder (GAD). Despite undergoing cognitive behavioural therapy for a few sessions, his symptoms continue to significantly impact his daily routine. He inquires about the possibility of taking medication for his anxiety.
What is the primary drug class used to treat GAD?Your Answer: Selective serotonin reuptake inhibitor (SSRI)
Explanation:The first-line pharmacological treatment for GAD, according to NICE, is selective serotonin reuptake inhibitors (SSRIs) like sertraline. Benzodiazepines should only be used for a short period during a crisis due to their association with dependence and tolerance. If SSRIs or SNRIs cannot be tolerated, pregabalin may be considered as a third-line treatment. SNRIs like venlafaxine or paroxetine are recommended as a second-line treatment. Tricyclic antidepressants are not recommended for GAD but may be effective for panic disorder, although caution should be taken in patients with a history of self-harm or suicidal ideation due to their toxicity in overdose.

A 70-year-old man comes in for his routine psychiatric follow-up appointment. He has a history of schizophrenia that has been difficult to manage, but has been stable for the past 5 years on various antipsychotic medications. He also has type II diabetes. During the appointment, he reports experiencing repetitive, involuntary movements of his lips and tongue, including lip smacking and grimacing. Which medication is the most likely culprit for these symptoms?
Your Answer: Risperidone
Correct Answer: Haloperidol
Explanation:Understanding Tardive Dyskinesia and its Association with Antipsychotic Drugs
Tardive dyskinesia is a disorder characterized by involuntary and repetitive movements, including lip puckering, excessive blinking, and pursing of the lips. This condition is commonly associated with the use of typical (older generation) antipsychotics such as haloperidol, prochlorperazine, and flupentixol. However, newer generation (atypical) antipsychotics like olanzapine, quetiapine, risperidone, and clozapine have a lower risk of causing tardive dyskinesia.
If tardive dyskinesia is diagnosed, the causative drug should be discontinued. It is important to note that the dyskinesia may persist for months after drug withdrawal and may even be permanent. Metformin is not linked to tardive dyskinesia.
Risperidone is an atypical antipsychotic used to treat schizophrenia, bipolar disorder, and autism. Current evidence suggests that the risk of developing tardive dyskinesia is lower than with typical antipsychotic use. To prevent tardive dyskinesia in chronic psychoses, it is recommended to use the lowest effective dose for the shortest possible time, while balancing the fact that increased doses are more beneficial to prevent recurrence.

A patient is brought to see you by his daughter. She is very concerned about him, saying that over the last few weeks, he has been hiding himself in their bedroom, heard to be talking to himself and accusing her of stealing his secret work and selling it to the government.
You conduct a mental state examination and elicit the following symptoms.
Which of these symptoms is a negative symptom?Your Answer: Blunted affect
Explanation:Understanding Symptoms of Schizophrenia
Schizophrenia is a mental disorder that affects a person’s ability to think, feel, and behave clearly. It is characterized by a range of symptoms, including positive and negative symptoms. Positive symptoms are those that reflect an increase or excess of the sufferer’s normal function, while negative symptoms are those that reflect a decrease or loss of normal function.
Blunted affect, social withdrawal, apathy, and anhedonia are examples of negative symptoms. These symptoms can be very prominent and are often associated with a less favorable prognosis. On the other hand, auditory hallucinations, delusions of grandeur, and thought echo are examples of positive symptoms.
Delusions of passivity, which imply that a person feels their actions, feelings, or impulses are being controlled by an external force, are not negative symptoms. It is important to understand the different symptoms of schizophrenia to properly diagnose and treat the disorder.

A 50-year-old man with schizophrenia who is on chlorpromazine experiences a bilateral resting tremor. Which side effect of antipsychotic medication does this exemplify?
Your Answer: Parkinsonism
Explanation:Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. They are associated with extrapyramidal side-effects and hyperprolactinaemia, which are less common with atypical antipsychotics.
Extrapyramidal side-effects (EPSEs) are common with typical antipsychotics and include Parkinsonism, acute dystonia, sustained muscle contraction, akathisia, and tardive dyskinesia. The latter is a late onset of choreoathetoid movements that may be irreversible and occur in 40% of patients. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients, including an increased risk of stroke and venous thromboembolism. Other side-effects include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval.

A 65-year-old Asian woman presents with sudden onset paranoid thoughts and suicidal ideation. She has a medical history of hypertension, type 2 diabetes mellitus, and hypercholesterolemia. Given her age and first episode of psychosis, what crucial investigation is necessary to rule out other potential underlying causes?
Your Answer: HbA1c
Correct Answer: CT head
Explanation:When elderly patients present with sudden onset psychosis, it is important to consider and rule out organic causes before attributing it to a primary psychotic disorder. In such cases, a CT head scan or even an MRI should be considered to detect any underlying organic causes such as a brain tumour, stroke or CNS infection. While HbA1c is typically used to assess diabetes control, PET scans are more commonly used to provide detailed information about metabolic processes in tissues, such as identifying active cancer cells. Chest X-rays may also be useful in certain cases.
Thought disorders can manifest in various ways, including circumstantiality, tangentiality, neologisms, clang associations, word salad, Knight’s move thinking, flight of ideas, perseveration, and echolalia. Circumstantiality involves providing excessive and unnecessary detail when answering a question, but eventually returning to the original point. Tangentiality, on the other hand, refers to wandering from a topic without returning to it. Neologisms are newly formed words, often created by combining two existing words. Clang associations occur when ideas are related only by their similar sounds or rhymes. Word salad is a type of speech that is completely incoherent, with real words strung together into nonsensical sentences. Knight’s move thinking is a severe form of loosening of associations, characterized by unexpected and illogical leaps from one idea to another. Flight of ideas is a thought disorder that involves jumping from one topic to another, but with discernible links between them. Perseveration is the repetition of ideas or words despite attempts to change the topic. Finally, echolalia is the repetition of someone else’s speech, including the question that was asked.
