As an F2 in psychiatry, you come across the notes of a 27-year-old man who is noted to prefer solitude, has never been in a romantic relationship, and has no desire for one. He also displays minimal interest in engaging in sexual activities with others. Despite performing well at work, he places little importance on feedback from his colleagues. Based on this information, which personality disorder is most likely present in this individual?
Your Answer: Antisocial
Correct Answer: Schizoid
Explanation:Schizoid personality disorder is characterized by a preference for solitude, a lack of interest in close relationships, and a low libido. It is important to note that while asexuality is recognized as part of the LGBTQ+ spectrum, it is not included in the diagnostic criteria for this disorder. The DSM-5 and ICD-10 both list a lack of desire for close relationships, a preference for solitary activities, and a limited capacity for expressing emotions as key features of schizoid personality disorder. Individuals with this disorder may also appear indifferent to praise or criticism, lack close friends or confidants, and exhibit emotional detachment or flattened affectivity. In contrast, borderline personality disorder is characterized by emotional instability in relationships, including sudden mood swings, rages, self-harming behaviors, and intense jealousy. Dependent personality disorder involves a reliance on others for reassurance and decision-making.
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.

Question 2
Incorrect

A 20-year-old individual presents with obsessive thoughts about causing harm to others since moving away from home to attend college. They are particularly anxious about using the shared kitchen in their dormitory and tend to prepare and eat meals during the night to avoid contact with their roommates. After completing a Yale-Brown Obsessive Compulsive Scale (Y-BOCS), they are diagnosed with mild OCD. What treatment option would be most suitable for this individual?
Your Answer: Clomipramine
Correct Answer: Cognitive behavioural therapy
Explanation:For patients with mild symptoms of obsessive-compulsive disorder (OCD) and mild impairment, the recommended first-line treatment is cognitive behavioural therapy (CBT) with exposure and response prevention (ERP). While clomipramine, a tricyclic antidepressant, may be used in some cases, it is not typically the first choice. Dialectical behaviour therapy is not commonly used in the treatment of OCD, as CBT and ERP are more effective. Fluoxetine, an SSRI antidepressant, may also be used in the treatment of OCD, but is not typically the first-line treatment for mild cases.
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.

Question 3
Correct

Which of the following interventions is most likely to be beneficial for a patient with early-onset schizophrenia?
Your Answer: Cognitive behavioural therapy
Explanation:Management of Schizophrenia: NICE Guidelines
Schizophrenia is a complex mental disorder that requires careful management. In 2009, the National Institute for Health and Care Excellence (NICE) published guidelines on the management of schizophrenia. According to these guidelines, oral atypical antipsychotics should be the first-line treatment for patients with schizophrenia. Additionally, cognitive behavioural therapy should be offered to all patients to help them manage their symptoms and improve their quality of life.
It is also important to pay close attention to cardiovascular risk-factor modification in patients with schizophrenia. This is because schizophrenic patients have high rates of cardiovascular disease, which is linked to antipsychotic medication and high smoking rates. Therefore, healthcare providers should work with patients to modify their lifestyle habits and reduce their risk of developing cardiovascular disease.
Overall, the NICE guidelines provide a comprehensive approach to managing schizophrenia. By following these guidelines, healthcare providers can help patients with schizophrenia achieve better outcomes and improve their overall health and well-being.

Question 4
Incorrect

A 30-year-old man visits his GP for a medication review. He began taking citalopram four months ago to treat his depression, and he now feels that his symptoms have significantly improved. He believes that he has returned to his usual self and no longer requires the antidepressant medication. What advice should the GP provide to minimize the risk of relapse?
Your Answer: Continue citalopram for 2 more months
Correct Answer: Continue citalopram for 6 more months
Explanation:Antidepressant medication should be continued for a minimum of 6 months after symptoms have remitted to reduce the risk of relapse. Therefore, the correct course of action is to continue treatment for 6 more months from the point of remission. Continuing for only 2 or 3 more months would not meet the recommended duration of treatment. Gradually reducing doses over 4 weeks is a suitable approach for weaning off SSRIs, but it should only be done after the 6-month period of treatment. Stopping citalopram abruptly is not safe and could lead to discontinuation syndrome or a relapse of depression.
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.

Question 5

A 25-year-old woman with schizophrenia visits you with her caregiver on a Monday morning. She informs you that she was out of town over the weekend and misplaced her prescribed clozapine, which she takes at a dosage of 200 mg in the morning and 400 mg at night. She hasn't taken any since Friday evening and seems to be experiencing psychotic symptoms. Her caregiver mentions that this is the first time she has ever lost her medication.
What course of action should you take?Your Answer: Restart clozapine at 150 mg mane, 300 mg nocte
Correct Answer: Restart clozapine at the starting dose of 12.5 mg daily
Explanation:Managing Non-Compliance with Clozapine in Schizophrenia Patients
When a patient with schizophrenia on clozapine misses their medication for more than 48 hours, it is important to manage the situation appropriately. Restarting clozapine at the starting dose of 12.5 mg daily is recommended, even if the patient has been on a higher dose previously. However, the titration upwards can be more rapid than for a clozapine-naive patient.
Stopping the clozapine prescription completely is not advisable, as the patient needs to be on treatment for their schizophrenia, and clozapine is often the treatment of choice for those who are resistant to other anti-psychotic medications. Restarting clozapine at a higher dose than the starting dose is also not recommended.
Switching to a depo form of anti-psychotic medication may be considered if non-compliance is a recurring issue, but it should be a decision made in consultation with the patient, their family, and their healthcare team. However, switching to a depo after one incidence of non-compliance may be an overreaction, especially as it would require a change of medication.
In summary, managing non-compliance with clozapine in schizophrenia patients requires careful consideration of the patient’s individual circumstances and consultation with their healthcare team. Restarting clozapine at the starting dose is the recommended course of action, and switching to a depo form of medication should be considered only after careful discussion.

A 22-year-old college student presents with insomnia, anxiety, and flashbacks. She experienced a traumatic event two weeks ago when a young man demanded her phone and purse while she was walking home from a party. She was alone and feared for her safety. Since then, she has been struggling with nightmares and flashbacks, which have disrupted her sleep. She has also been avoiding going out alone. She is seeking medication to help her sleep. What is her response?
Your Answer: Post traumatic stress disorder
Correct Answer: Acute stress disorder
Explanation:Acute stress disorder is a type of acute stress reaction that occurs within four weeks of a traumatic event, while PTSD is diagnosed after four weeks have passed. Although this patient’s symptoms have the potential to develop into PTSD, they currently meet the criteria for acute stress disorder. It is important to monitor their progress and reassess in two weeks.
Panic disorder is characterized by recurrent panic attacks and is often accompanied by agoraphobia. To be diagnosed with panic disorder, the individual must experience persisting anxiety about the recurrence of attacks for at least one month after the initial episode.
Depression is characterized by persistent feelings of sadness or loss of pleasure in activities, along with a range of emotional, cognitive, physical, and behavioral symptoms.
Generalized anxiety disorder is characterized by excessive and uncontrollable worry that is pervasive and persistent, along with a range of somatic, cognitive, and behavioral symptoms. This disorder must be present for longer than two weeks and is typically experienced on a continuum of severity.
Acute stress disorder is a condition that occurs within the first four weeks after a person has experienced a traumatic event, such as a life-threatening situation or sexual assault. It is characterized by symptoms such as intrusive thoughts, dissociation, negative mood, avoidance, and arousal. These symptoms can include flashbacks, nightmares, feeling disconnected from reality, and being hypervigilant.
To manage acute stress disorder, trauma-focused cognitive-behavioral therapy (CBT) is typically the first-line treatment. This type of therapy helps individuals process their traumatic experiences and develop coping strategies. In some cases, benzodiazepines may be used to alleviate acute symptoms such as agitation and sleep disturbance. However, caution must be taken when using these medications due to their addictive potential and potential negative impact on adaptation. Overall, early intervention and appropriate treatment can help individuals recover from acute stress disorder and prevent the development of more chronic conditions such as PTSD.

A 32-year-old with a long standing history of schizophrenia presents to the emergency department in status epilepticus. After receiving treatment, he informs the physician that he has been experiencing frequent seizures lately.
Which medication is the most probable cause of his seizures?Your Answer: Clozapine
Explanation:Seizures are more likely to occur with the use of clozapine due to its ability to lower the seizure threshold. This is a known side-effect of the atypical antipsychotic, which is commonly prescribed for treatment resistant schizophrenia.
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 40-year-old woman is being evaluated in the Psychiatry Clinic following her third suicide attempt in the past two years. She had cut her wrist at home and was brought to the hospital after her sister found her unconscious. She was successfully resuscitated, received a blood transfusion, and was discharged after a few days in hospital. She has been diagnosed with bipolar disorder since her teenage years and works in retail. She is currently single after having had unsuccessful relationships in the past. She consumes a moderate amount of alcohol and smokes around ten cigarettes a day. She is currently taking lithium for her mental illness. She is otherwise healthy and does not suffer from any medical conditions. What will be included in her long-term risk management plan?
Your Answer: Comprehensive psychosocial assessment of needs and risks
Explanation:Best Practices for Suicide Risk Management
Comprehensive psychosocial assessment of needs and risks is recommended by NICE to identify the needs of the patient and potential risks. However, the use of risk assessment tools to predict future danger is not advised due to their limited predictive value. Instead, a holistic approach considering biological, psychological, and social factors is more effective in identifying patients at high risk of suicide.
Establishing a crisis plan with the patient is part of the risk management strategy advocated by NICE. This plan includes self-management strategies and guidance on accessing emergency services if necessary. Asking about suicide plans and establishing a crisis plan does not increase suicide risk.
Confidentiality is crucial in the doctor-patient relationship, but it may need to be broken if the patient poses a serious risk to themselves or others. Therefore, informing the patient that confidentiality will always be maintained is incorrect.
While psychiatric medications are commonly used to manage underlying mental illnesses, NICE advises against prescribing them specifically to reduce self-harm. A tailored approach to medication management is necessary for each patient.
Overall, a comprehensive and individualized approach to suicide risk management is essential for effective prevention.

A 20-year-old man with moderate learning difficulty visits your clinic with his father. His father complains that he has trouble sleeping at night and frequently wakes up, disrupting his own sleep and causing him to be excessively drowsy during the day. He frequently takes a nap in the late afternoon, which is impacting his ability to participate in local community services. They have already attempted conventional sleep hygiene recommendations. Given the history of learning difficulty, what would be the most appropriate medication to assist with his sleep problems?
Your Answer: Melatonin
Explanation:Medication Options for Sleep Disturbance in Patients with Learning Disabilities
Patients with learning disabilities often experience chronic sleep-wake cycle disruption, leading to insomnia. Melatonin has been found to be effective in regulating natural sleep-wake cycles and treating insomnia in these patients. However, it is not licensed for use in individuals under 55 years old and should only be prescribed by a psychiatrist with expertise in sleep disturbance in learning disability.
Other medications, such as zopiclone, diazepam, promethazine, and trazodone, can also be used for insomnia. Zopiclone is helpful for patients with trouble falling asleep, while diazepam can be used for anxiety and sedation but may lead to dependence. Promethazine is useful for maintaining sleep, particularly in cases of agitation or insomnia. Trazodone, on the other hand, is an antidepressant medication with sedating properties and is typically used for patients with depression and sleep disturbance.
However, given the history of learning disability in the stem, melatonin would be the most appropriate medication to trial in this patient. It is important to consult with a psychiatrist with expertise in sleep disturbance in learning disability to determine the best course of treatment.

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.

A 55-year-old man with a history of paranoid schizophrenia experiences a recurrence of symptoms due to irregular medication intake, leading to his admission under section 2 of the Mental Health Act following a formal mental state assessment. He had been taking Risperidone orally once daily for several years, which had effectively stabilized his mental state while living in the community. Considering his non-adherence, what treatment option would be most appropriate for this individual?
Your Answer:
Correct Answer: Switching to a once monthly IM anti-psychotic depo injection
Explanation:Patients who struggle with taking their antipsychotic medication as prescribed may benefit from receiving a once monthly intramuscular depo injection. It is important to maintain a stable mental state and overall well-being for these patients, and switching medications can increase the risk of relapse and recurring symptoms. The goal is to provide the least restrictive treatment possible and minimize hospitalization time as outlined by the Mental Health Act. While daily visits from a home treatment team to administer medication may be a temporary solution, it is not a sustainable long-term option. Similarly, a once-daily intramuscular injection may not be practical or feasible for the patient.
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.

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:
Correct 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 32-year-old male visits his primary care physician complaining of new and concerning symptoms. He has a medical history of schizophrenia, which was diagnosed at the age of eighteen and is currently managed with olanzapine. He has not undergone any surgical procedures and is generally in good health.
What are the symptoms he is likely to be experiencing?Your Answer:
Correct Answer: Polyuria and polydipsia
Explanation:Long-term use of atypical antipsychotics can result in glucose dysregulation and diabetes, with polyuria and polydipsia being common symptoms. While these drugs are preferred for treating schizophrenia due to their reduced extrapyramidal side effects, they can also cause metabolic dysregulation leading to insulin resistance and diabetes. Diarrhoea is an unlikely side effect, as these drugs tend to cause constipation instead. Sexual dysfunction is a more common side effect than priapism, and the mechanism behind it is not fully understood. Tinnitus is not a likely side effect in this case, as the patient does not have a history of depression or SSRI use. Weight gain is the most common side effect of long-term atypical antipsychotic use, due to the metabolic disturbances they cause.
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 26-year-old man comes for his scheduled psychiatry visit after being prescribed Risperidone for his recent diagnosis of schizophrenia. Although he has been stable since starting this medication, he reports experiencing milky discharge from both nipples and inquires about alternative medications that can manage his schizophrenia without causing this side effect. What would be the most suitable medication to consider as an alternative?
Your Answer:
Correct Answer: Aripiprazole
Explanation:Aripiprazole is the most suitable medication to try for this patient as it has the least side effects among atypical antipsychotics, especially in terms of prolactin elevation. This is important as the patient’s nipple discharge is likely caused by high prolactin levels. Chlorpromazine, a typical antipsychotic, is not recommended as it has a higher risk of extrapyramidal side effects. Clozapine, another atypical antipsychotic, is not appropriate for this patient as it is only used for treatment-resistant schizophrenia and requires two other antipsychotics to be trialled first. Haloperidol, a typical antipsychotic, is also not recommended due to its higher risk of extrapyramidal side effects.
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.

A 29-year-old woman presents with dry, eczematous hands. She reports being a very hygienic person, but since the onset of the COVID-19 pandemic, she has been washing her hands excessively - up to 60 times a day. She is aware that this is causing her skin to become dry and irritated, but her anxiety about contracting the virus is too great to stop. She works in a hospital and is worried about her colleagues noticing her frequent hand washing. You suspect she may have obsessive-compulsive disorder and decide to refer her to the community mental health team. What treatment options are likely to be offered to her?
Your Answer:
Correct Answer: Cognitive behavioural therapy
Explanation: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 54-year-old man visits his General Practitioner (GP) with his wife. Since retiring from the navy, he has been struggling with anger issues. This is affecting his marriage, and he has been drinking more heavily to help him to relax. He also reports feeling low in mood and having frequent nightmares, including flashbacks from his past experiences while fighting in Afghanistan.
Which one of the following psychological therapies would be most appropriate to manage this condition?Your Answer:
Correct Answer: Trauma-focused cognitive behavioural therapy
Explanation:Different Approaches to Treating PTSD in Combat-Related Trauma
When it comes to treating post-traumatic stress disorder (PTSD) caused by combat-related trauma, there are several approaches available. Trauma-focused cognitive behavioural therapy is often recommended, which involves educating the patient about their reactions to trauma and providing strategies for managing symptoms. Anger management may also be appropriate if the patient is only experiencing anger without other PTSD symptoms. However, eye movement desensitisation and reprocessing (EMDR) is not the most suitable treatment for combat-related trauma. Psychoanalytic therapy, which involves exploring the unconscious to resolve underlying conflicts, is also not recommended. Finally, psychologically focused debriefing is not recommended for treating PTSD in combat- or non-combat-related trauma. It’s important to consider the specific needs of each patient and tailor treatment accordingly.

She has been experiencing obsessive thoughts about her loved ones being harmed and feels compelled to perform certain rituals to prevent this from happening. She spends hours each day checking and rechecking that appliances are turned off and doors are locked. Her relationships are suffering, and she is struggling to maintain her job. She is hesitant to take medication but is open to exploring other treatment options.
What is the most appropriate psychological approach for managing OCD in this case?Your Answer:
Correct 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 95-year-old man without past medical history presents with increasing forgetfulness. His son is concerned that over the last six weeks his father has been forgetting his grandchildren's names and stories from his upbringing. The patient reports a loss of appetite, sometimes forgetting if he has eaten, is not getting good quality sleep and is frustrated with his son for taking him to the doctors. He sometimes sees and hears his recently deceased wife.
Based on these symptoms, what is the most probable diagnosis for this patient?Your Answer:
Correct Answer: Depression
Explanation:Pseudodementia, which is characterized by global memory loss rather than short-term memory loss, can be mistaken for dementia but is actually a symptom of severe depression.
The correct diagnosis in this case is depression, as the patient’s symptoms are consistent with pseudodementia, which is a common mimic for dementia in elderly patients. While some cognitive impairment is present, the key feature is a global memory loss affecting both short and long-term memory over a short period of four weeks, with reluctance to engage in clinical assessment. The recent loss of the patient’s husband also suggests a severe reactive depressive episode.
Alzheimer’s dementia is a possible differential diagnosis due to the patient’s age, but it tends to present more gradually with selective impairment of short-term memory and relative sparing of longer-term memories.
Frontotemporal lobe dementia is less likely in this case as it tends to present with more dramatic behavioral changes or emotional disinhibition.
Lewy body dementia shares some symptoms with this case, such as impaired cognition and visual hallucinations. However, the specific hallucination of the patient’s husband is more likely related to grief and depression, which is supported by the relatively short duration of symptoms. Question stems that describe Lewy body dementia may also provide clues towards a movement disorder.
Differentiating between Depression and Dementia
Depression and dementia are two conditions that can have similar symptoms, making it difficult to distinguish between the two. However, there are certain factors that can suggest a diagnosis of depression over dementia.
One of the key factors is the duration and onset of symptoms. Depression often has a short history and a rapid onset, whereas dementia tends to develop slowly over time. Additionally, biological symptoms such as weight loss and sleep disturbance are more commonly associated with depression than dementia.
Patients with depression may also express concern about their memory, but they are often reluctant to take tests and may be disappointed with the results. In contrast, patients with dementia may not be aware of their memory loss or may not express concern about it.
The mini-mental test score can also be variable in patients with depression, whereas in dementia, there is typically a global memory loss, particularly in recent memory.
In summary, while depression and dementia can have overlapping symptoms, careful consideration of the duration and onset of symptoms, biological symptoms, patient concerns, and cognitive testing can help differentiate between the two conditions.

Samantha, a 35-year-old woman, arrives at the emergency department complaining of severe, sharp pain on her left side that radiates to her lower abdomen and groin. The pain comes and goes in waves and has been ongoing for 10 hours. She also reports an increased frequency of urination and a burning sensation while urinating. A urine dip reveals haematuria but no signs of infection. You request the following blood tests:
Calcium 3.3 mmol/L (2.1-2.6)
Corrected Calcium 3.4 mmol/L (2.1-2.6)
Phosphate 0.6 mmol/L (0.8-1.4)
Magnesium 0.8 mmol/L (0.7-1.0)
Thyroid stimulating hormone (TSH) 4.9 mU/L (0.5-5.5)
Free thyroxine (T4) 9.5 pmol/L (9.0 - 18)
Parathyroid hormone 85 pg/mL (10-65 )
Which medication's long-term use is responsible for Samantha's condition?Your Answer:
Correct Answer: Lithium
Explanation:Hyperparathyroidism and subsequent hypercalcaemia can occur with prolonged use of lithium. This can lead to the formation of kidney stones due to excessive calcium concentration. Amitriptyline, a sedative tricyclic antidepressant, is not likely to cause nephrolithiasis or explain the patient’s elevated calcium and parathyroid hormone levels. Similarly, clozapine, a second-generation antipsychotic, is not known to cause hypercalcaemia or hyperparathyroidism. Sertraline, a selective serotonin reuptake inhibitor, typically causes side effects during initiation or discontinuation, such as sexual dysfunction and gastrointestinal issues. Checking thyroid function tests may also be helpful as lithium use can lead to hypothyroidism.
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.

Which is the most appropriate initial form of psychotherapy?Your Answer:
Correct Answer: Self-help group
Explanation:Different Forms of Therapy for Alcohol Dependence: Pros and Cons
Alcohol dependence is a serious issue that requires professional intervention. There are various forms of therapy available for individuals struggling with alcohol abuse. Here are some of the most common types of therapy and their pros and cons:
1. Self-help group: Alcoholics Anonymous (AA) and similar self-help programs are free, widely available, and confidential. The diversity of membership, vast experience with alcohol among participants, and flexibility of meeting times provide therapeutic advantages. However, the lack of accountability and wide variation in quality among different groups can be a disadvantage.
2. Interpersonal psychotherapy and antidepressants: Interpersonal psychotherapy deals with specific circumstances thought to contribute to depression, including losses, social transitions, role disputes, and unsatisfactory interpersonal relations. Antidepressants are only considered after a month of abstinence. However, this form of therapy may not be suitable for everyone.
3. Cognitive behavioural therapy (CBT): CBT may be useful for addressing underlying reasons for alcohol abuse in the long run. However, first-line support for patients with addiction is self-help groups such as AA.
4. Structural family therapy: This form of treatment is developed for helping families in which a child shows psychiatric symptoms, behaviour problems, or unstable chronic illness. However, it may not be suitable for patients with isolated alcoholism or fractured families.
5. Psychoanalytic psychotherapy: This therapy posits that therapeutic change requires making early experiences conscious and their influence explicit. However, it may not be suitable for everyone and may require a longer time commitment.
In conclusion, there are various forms of therapy available for individuals struggling with alcohol dependence. It is important to consider the pros and cons of each type of therapy and choose the one that is most suitable for the individual’s needs.

A 28-year-old woman with a history of depression comes in 2 months postpartum with symptoms of low mood, lack of energy, and loss of pleasure for the past 3 weeks. She is currently breastfeeding. She has previously taken fluoxetine and found it effective but stopped during pregnancy. After a conversation, she has decided to resume her medication.
Which antidepressant would be the best choice to initiate treatment?Your Answer:
Correct Answer: Sertraline
Explanation:Understanding Postpartum Mental Health Problems
Postpartum mental health problems can range from mild ‘baby-blues’ to severe puerperal psychosis. To screen for depression, healthcare professionals may use the Edinburgh Postnatal Depression Scale, which is a 10-item questionnaire that indicates how the mother has felt over the previous week. A score of more than 13 indicates a ‘depressive illness of varying severity’, with sensitivity and specificity of more than 90%. The questionnaire also includes a question about self-harm.
‘Baby-blues’ is seen in around 60-70% of women and typically occurs 3-7 days following birth. It is more common in primips, and mothers are characteristically anxious, tearful, and irritable. Reassurance and support from healthcare professionals, particularly health visitors, play a key role in managing this condition. Most women with the baby blues will not require specific treatment other than reassurance.
Postnatal depression affects around 10% of women, with most cases starting within a month and typically peaking at 3 months. The features are similar to depression seen in other circumstances, and cognitive behavioural therapy may be beneficial. Certain SSRIs such as sertraline and paroxetine may be used if symptoms are severe. Although these medications are secreted in breast milk, they are not thought to be harmful to the infant.
Puerperal psychosis affects approximately 0.2% of women and requires admission to hospital, ideally in a Mother & Baby Unit. Onset usually occurs within the first 2-3 weeks following birth, and features include severe swings in mood (similar to bipolar disorder) and disordered perception (e.g. auditory hallucinations). There is around a 25-50% risk of recurrence following future pregnancies. Paroxetine is recommended by SIGN because of the low milk/plasma ratio, while fluoxetine is best avoided due to a long half-life.

You're a medical student on your psychiatry placement. You are performing a mental state examination on one of the patients on the inpatient psychiatry ward, a 22-year-old man who was admitted 2 days ago.
Whenever you ask him a question, you notice that he repeats the question back to you. You notice that he is also repeating some of the phrases you use.
What form of thought disorder is this an example of?Your Answer:
Correct Answer: Echolalia
Explanation:Echolalia is the repetition of someone else’s speech, including the questions being asked. Clang association is when someone uses words that rhyme with each other or sound similar. Neologism is the formation of new words. Perseveration is when ideas or words are repeated several times.
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.

You are discussing bipolar disorder with your consultant in a geriatric trainees teaching session as part of your psychiatry attachment.
Which of the following is the most common medical treatment in the long-term management of bipolar disorder in older adults?Your Answer:
Correct Answer: Lithium
Explanation:Pharmacological Treatments for Bipolar Disorder
Bipolar disorder, also known as manic depression, is a mental health condition characterized by alternating episodes of mania and depression. Lithium is the most commonly used medication for long-term management of bipolar disorder. It helps to stabilize mood and prevent relapses of both manic and depressive episodes. However, it is important to note that medication alone is not enough to manage bipolar disorder effectively. Holistic care, including therapy and lifestyle changes, is essential for patients to cope with their condition.
Carbamazepine is another medication used for mood stabilization in bipolar disorder, but it is less commonly used than lithium. Sertraline, on the other hand, is a selective serotonin reuptake inhibitor (SSRI) that is primarily used to treat depression, not bipolar disorder. Diazepam, a benzodiazepine, may be helpful in managing acute manic episodes, but it is not recommended for long-term use due to the risk of dependence.
Clozapine is an atypical antipsychotic medication that is primarily used to treat treatment-resistant schizophrenia. It is not commonly used for bipolar disorder due to the risk of agranulocytosis, a potentially life-threatening condition that can occur with clozapine use. If clozapine is used for bipolar disorder, it should only be done under close monitoring and evaluation by a multidisciplinary psychiatric team.
In summary, lithium is the most commonly used medication for long-term management of bipolar disorder, but holistic care is essential for effective management of the condition. Other medications may be used in certain situations, but they should be used with caution and under close supervision.

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:
Correct 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.

The risk of developing schizophrenia if one monozygotic twin is affected is approximately:
Your Answer:
Correct Answer: 50%
Explanation:Understanding the Epidemiology of Schizophrenia
Schizophrenia is a psychotic disorder that affects a significant portion of the population. The strongest risk factor for developing this condition is having a family history of the disorder. Individuals with a parent who has schizophrenia have a relative risk of 7.5. Additionally, monozygotic twins have a 50% chance of developing schizophrenia, while siblings have a 10% chance. In contrast, individuals without relatives with schizophrenia have a 1% chance of developing the disorder.
Aside from family history, other factors can increase the risk of developing schizophrenia. Black Caribbean ethnicity has a relative risk of 5.4, while migration and living in an urban environment have relative risks of 2.9 and 2.4, respectively. Cannabis use also increases the risk of developing schizophrenia, with a relative risk of 1.4.
Understanding the epidemiology of schizophrenia is crucial in identifying individuals who may be at risk of developing the disorder. By recognizing these risk factors, healthcare professionals can provide early interventions and support to prevent or manage the onset of schizophrenia.

A 25-year-old male is diagnosed with schizophrenia. He lives at home with his mother and two younger siblings. Although the patient has shown no signs of violence so far, his mother is very concerned for her own safety and that of her other two children. She wishes to discuss this with the psychiatry team.
Which of the following statements is true about the relationship between schizophrenia and violence?Your Answer:
Correct Answer: People with schizophrenia are responsible for about a twentieth of homicides in the UK
Explanation:The Complex Association Between Schizophrenia and Homicide in the UK
The relationship between mental illness, specifically schizophrenia, and violence is a complex and sensitive topic. While there have been high-profile cases of homicides committed by individuals with mental illness, it is important to keep this association in perspective. In fact, the vast majority of homicides in the UK are committed by individuals who are not mentally ill.
However, research from the National Confidential Inquiry into Suicides and Homicides by People with Mental Illness has found that individuals with schizophrenia are responsible for around 5% of homicides, compared to a population prevalence of around 1%. This over-representation suggests that there may be a connection between schizophrenia and violence.
It is important to note that this increased association with homicide is still relatively rare, with only around 30 homicides a year in the UK committed by individuals with schizophrenia. Additionally, the stigma surrounding mental illness should not be further perpetuated by this association.
In contrast, there is no significant association between obsessional-compulsive disorder (OCD) and violence. It is crucial to approach the topic of mental illness and violence with care and understanding, while also acknowledging the potential risks and challenges that individuals with schizophrenia may face.

A 30-year-old man without known psychiatric history is admitted to the psychiatry ward, after presenting to the emergency department with delusions and homicidal ideations.
Following a negative drugs screen, antipsychotic treatment is initiated with haloperidol.
The patient is reviewed 3-hours after the initiation of treatment and is noted to have a sustained upward deviation of both eyes. When asked, he reports that his eyes are extremely painful.
What is the most appropriate initial management option based on the likely diagnosis?Your Answer:
Correct Answer: Procyclidine
Explanation:Acute dystonic reactions, such as oculogyric crisis, can occur within the first 4 days of starting or increasing the dose of antipsychotic medication. These reactions can be treated with anticholinergic procyclidine, which can take effect within 5 minutes. To prevent future attacks, the dose of antipsychotic medication may need to be reduced.
Benzodiazepines, such as diazepam, are not effective in treating acute dystonic reactions. However, they can be used to treat serotonin syndrome, which can occur after taking serotonin agonists like SSRIs and MAOIs. Serotonin syndrome presents with rigidity, hyperreflexia, and autonomic dysfunction.
Levodopa, a dopamine precursor used to treat Parkinson’s disease, is not effective in managing extrapyramidal side effects (EPSEs) caused by antipsychotic medication. EPSEs are caused by dopamine blockage at the mesolimbic pathway, not a dopamine deficiency.
IV fluids are not helpful in treating oculogyric crisis. However, they can be useful in treating neuroleptic malignant syndrome, another side effect that can occur with antipsychotic treatment. Neuroleptic malignant syndrome presents with lead-pipe muscle rigidity, fever, and autonomic dysfunction.
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.

Question 28
Incorrect

A 28-year-old patient presents with sudden paralysis in their right leg and left arm, four weeks after being involved in a car accident. Despite being discharged from the hospital without injuries, they woke up this morning unable to move these limbs. There is no pain, but the paralysis is causing significant distress. On examination, there are no visible injuries, normal tone, and intact sensation in all four limbs. All reflexes are normal, but power in the affected limbs is MRC 0/5, while the contralateral limbs are MRC 5/5. Hoover's sign is positive on the affected leg, and there are no abnormalities in the cranial nerve exam. What is the likely diagnosis?
Your Answer:
Correct Answer: Conversion disorder
Explanation:Conversion disorder is a condition that typically involves the loss of motor or sensory function and may be triggered by stress. In this case, the patient has experienced a stressful accident and is now exhibiting functional paralysis, without voluntary movement but some involuntary movements due to reflexes and a positive Hoover’s sign. This sign indicates that the unaffected leg is compensating for the affected leg’s lack of movement by contracting synergistically.
It is unlikely that the patient is suffering from factitious disorder, which involves feigning symptoms to gain attention from healthcare professionals. This is because the neurological symptoms and the recent stressful event suggest conversion disorder, and the presence of Hoover’s sign is not consistent with feigned paralysis.
Lacunar strokes, which cause paralysis on one side with contralateral sensory loss, would not present with this pattern of paralysis and would not be delayed in onset after the accident. Malingering, or faking symptoms for personal gain, is also unlikely at this stage.
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.

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:
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 28-year-old artist visits his GP complaining of anxiety related to social interactions. He prefers solitude and is hesitant to share his beliefs with others, which they find peculiar. During the consultation, the patient talks in a high-pitched voice about his fascination with horror movies and his 'spirit-guide' that protects him. However, he denies experiencing any visual or auditory hallucinations and does not display any delusional thinking. Additionally, there is no evidence of pressure of speech. What is the probable diagnosis?
Your Answer:
Correct Answer: Schizotypal personality disorder
Explanation:The man seeking help has social anxiety and prefers to be alone. He has an interest in paranormal phenomena and talks in a high-pitched voice when discussing his spirit guide. These symptoms suggest that he may have schizotypal personality disorder, which is characterized by magical thinking and odd speech patterns. Emotionally unstable personality disorder, histrionic personality disorder, schizoaffective disorder, and schizoid personality disorder are all incorrect diagnoses.
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.
