A 58-year-old woman is brought to the psychiatric ward by her family due to concerns about her behavior. During your conversation with her, you observe that she speaks rapidly and does not allow you to interrupt her. She frequently changes the subject, but you can discern connections between them. What psychiatric disorder is most commonly associated with these symptoms?
Your Answer: Bipolar disorder
Explanation:Mania is often characterized by flight of ideas, which is when a person speaks rapidly and jumps between different topics. This is a common symptom of bipolar disorder. It is important to differentiate flight of ideas from Knight’s move thinking, which is associated with schizophrenia. In flight of ideas, there are identifiable connections between the topics that the person jumps between, while in Knight’s move thinking, there are no apparent connections between the topics. This is referred to as loosening of association.
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.

A man has been hospitalised for severe psychiatric disease. The patient is unable to form new memories and, as such, is stuck in 1992, believing that the Gulf War is ongoing. He has been hospitalised since 1993. He is unaware of his memory problem and confabulates his story when you try to point out the discrepancies between his stories and reality. He is able to remember everything up until 1992 without any problem.
Which of the following is the most likely aetiology of his disorder?Your Answer: Vitamin B1 deficiency
Explanation:Common Nutrient Deficiencies and Associated Neurological Disorders
Vitamin B1 Deficiency:
Korsakoff’s amnesia is a severe neurological disorder caused by a deficiency in thiamine (vitamin B1). This condition is commonly seen in chronic alcoholics and is characterized by anterograde amnesia, confabulations, and bilateral loss of the mammillary bodies in the brain. Thiamine deficiency can also lead to beriberi, which presents with polyneuritis and symmetrical muscle wasting in the dry form and dilated cardiomyopathy in the wet form.Vitamin B6 Deficiency:
Vitamin B6 is essential for GABA synthesis, and its deficiency can lead to convulsions, neuropathy, and hyperirritability.Conversion Disorder:
Conversion disorder is a neurological condition characterized by the presence of a deficit, such as paralysis or numbness, without any identifiable somatic cause. Patients are usually unconcerned about the symptom but are aware of the problem.Vitamin B12 Deficiency:
Vitamin B12 deficiency can lead to macrocytic megaloblastic anemia, subacute combined neurodegeneration, and glossitis.Vitamin C Deficiency:
Vitamin C is essential for collagen synthesis, and its deficiency can lead to scurvy, which presents with swollen gums, easy bruising, anemia, and poor wound healing.Nutrient Deficiencies and Associated Neurological Disorders

Question 3
Correct

A 25-year-old woman visits her GP complaining of feeling down for the past 4 months. She reports having trouble sleeping and losing interest in activities she used to enjoy. Additionally, she has been experiencing excessive worry about the future. The patient has a history of dysmenorrhoea, which is managed with mefenamic acid. The GP recommends cognitive behavioural therapy and prescribes sertraline. What other medication should be considered given the patient's medical history?
Your Answer: Omeprazole
Explanation:To reduce the risk of gastrointestinal bleeding when taking both an SSRI and an NSAID like mefenamic acid, it is recommended to prescribe a PPI such as omeprazole. The combined oral contraceptive pill is not appropriate in this case as the patient is already taking mefenamic acid for dysmenorrhoea. Duloxetine, an SNRI, should not be prescribed as the patient has not yet tried an SSRI. Naproxen, another NSAID, is also not recommended as the patient is already taking mefenamic acid.
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 9-year-old patient is brought to the general practitioner by his parents because he has been disruptive at school. His teachers report that he does not pay attention in class, bullies other classmates and takes their food during lunchtime without their permission. One teacher also reported that the patient was seen hurting the class hamster.
What is the most probable diagnosis for this patient?Your Answer: Conduct disorder
Explanation:Differentiating between Conduct Disorder, Major Depression, Oppositional Defiant Disorder, Antisocial Disorder, and Manic Episode
Conduct Disorder, Major Depression, Oppositional Defiant Disorder, Antisocial Disorder, and Manic Episode are all mental health conditions that can present with similar symptoms. However, each disorder has its own unique characteristics that differentiate it from the others.
Conduct Disorder is a disorder that affects individuals under the age of 18 and is associated with disruptive, bullying behavior and often torture of animals. It is characterized by repetitive behavior that violates the rights of others.
Major Depression is associated with depressed mood, in addition to five of the following symptoms: sleep changes, loss of interest in previous hobbies or activities, guilt, decreased energy, difficulty concentrating, changes in appetite, sluggishness, and suicidal thoughts persisting for 2 weeks.
Oppositional Defiant Disorder is characterized by behavior in opposition to authority, but there is no violation of the rights of others or extreme behavior such as bullying or animal cruelty.
Antisocial Disorder is diagnosed in individuals who are 18 or older and exhibit signs of Conduct Disorder. It is characterized by a disregard for the rights of others and a lack of empathy.
Manic Episode is associated with elevated mood lasting for 7 days. These patients feel as though they have increased energy, do not need sleep, engage in risky sexual activity and sometimes illicit behavior, feel above the law or invincible, are easily distractible, have flight of fancy, are agitated, and have pressured speech.
It is important to differentiate between these disorders to ensure that individuals receive the appropriate treatment and support for their specific condition.

Question 5
Incorrect

You are requested to assess a 25-year-old man who has been urgently referred to the Community Mental Health Team. He has recently left his job to work on 'a groundbreaking project' which he believes will eradicate world poverty. He has also been neglecting his basic needs such as eating and sleeping as he 'cannot afford to waste time on such trivialities'. Upon examination, the patient appears restless and lacks awareness of their condition. The patient has a history of depression and is currently on an antidepressant medication.
What would be the most suitable course of action in managing this patient?Your Answer: Start lithium and continue antidepressant
Correct Answer: Start antipsychotic and stop antidepressant
Explanation:The appropriate management for a patient experiencing mania/hypomania while taking antidepressants is to discontinue the antidepressant and initiate antipsychotic therapy. This is because the patient’s symptoms, such as delusions of grandeur and hyperactivity, suggest an episode of mania, which requires the use of a rapidly acting antipsychotic or benzodiazepine. Electroconvulsive therapy (ECT) is not typically used for the treatment of mania, and lithium is not the first-line treatment for acute episodes of mania. Therefore, starting antipsychotic therapy and discontinuing antidepressants is the most appropriate course of action.
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 30-year-old woman visits her GP complaining of feeling down. She finds it difficult to work with her colleagues and believes they are not performing up to par. Consequently, she declines to delegate tasks and has become exhausted.
Upon further inquiry, she adheres to a strict daily routine and tries to avoid deviating from it as much as possible. If she fails to follow this plan, she becomes anxious and spends her free time catching up on tasks.
What is the most suitable course of action in managing her probable diagnosis?Your Answer: Dialectical behaviour therapy
Explanation:The female librarian seeking advice exhibits inflexible behavior in her work and becomes easily annoyed when her routines are disrupted. She prefers to work alone, relying on lists and rules to structure her day, which are indicative of obsessive-compulsive personality disorder (OCPD). Dialectical behavior therapy (DBT) is the recommended approach for managing personality disorders, including OCPD. Exposure and response prevention (ERP) and eye movement desensitization and reprocessing (EMDR) are not appropriate for her condition, as they are used to manage obsessive-compulsive disorder (OCD) and post-traumatic stress disorder (PTSD), respectively. Prescribing fluoxetine may be considered for any associated depression, but addressing the underlying cause with DBT is the initial priority.
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.

A 36-year-old woman presents to her doctor with complaints of struggling to maintain positive relationships with her coworkers. Upon further inquiry, it is revealed that the woman has a rigid value system and moral code, making it challenging for her to work with colleagues who have different beliefs and work practices. What personality disorder is most likely present in this patient?
Your Answer: Obsessive-compulsive personality disorder
Explanation:Patients with obsessive-compulsive personality disorder tend to be inflexible when it comes to morals, ethics, and values. They often have difficulty delegating tasks to others, as seen in this case. Other symptoms include an excessive focus on details, rules, lists, and order, as well as perfectionism that can interfere with completing tasks.
Antisocial personality disorder is not applicable in this case. This disorder is characterized by aggressive and unlawful behavior, deception, and a lack of empathy.
Borderline personality disorder is also not applicable. This disorder is characterized by unstable self-image, unstable relationships, fear of abandonment, and chronic feelings of emptiness.
Paranoid personality disorder is not applicable. This disorder is characterized by a tendency to question the loyalty of friends, hypersensitivity to insult, and preoccupation with conspiracies and hidden meanings.
Narcissistic personality disorder is not applicable. This disorder is characterized by a grandiose sense of self-importance, lack of empathy, sense of entitlement, and preoccupation with fantasies of success, power, or beauty.
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.

A 40-year-old Afro-Caribbean male has been diagnosed with schizophrenia for 3 years. To address his history of non-compliance, he has been prescribed a monthly 250 mg depo injection of zuclopenthixol. What is a typical side effect of this type of antipsychotic medication?
Your Answer: Parkinsonian symptoms
Explanation:Anti-psychotics often lead to Parkinsonian symptoms, while neuroleptic malignant syndrome is a rare but severe side effect that can be fatal.
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.

The patient has no significant medical history, denies alcohol dependence, and has recently been promoted at work. During the consultation, he remains with his arms folded and does not engage. There is no evidence of affection towards his father when he expresses his concern. What is the most likely diagnosis for this patient?
Your Answer: Schizoid personality disorder
Explanation: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.

A worried parent comes to your clinic with concerns that their 14-year-old son may be purging after meals. They have noticed that he has become increasingly preoccupied with his appearance and often disappears after eating. They want to know more about purging. What information can you provide them about this behavior?
Purging is a behavior that involves getting rid of food and calories from the body after eating. This can be done through self-induced vomiting, using laxatives or diuretics, or excessive exercise. Purging is often associated with eating disorders such as bulimia nervosa. It is important to note that purging can have serious health consequences, including dehydration, electrolyte imbalances, and damage to the digestive system. If their son is indeed purging, it is important to seek medical and psychological help as soon as possible.Your Answer: Purging behaviours can include exercising, laxatives or diuretics
Explanation:Bulimia nervosa involves purging behaviors that go beyond just vomiting, and can also include the use of laxatives or diuretics, as well as excessive exercising. Binging episodes are followed by these purgative behaviors, which occur on average once a week and do not necessarily happen after every meal. Fasting, which involves restricting or stopping food intake, is more commonly associated with anorexia nervosa.
Bulimia Nervosa: An Eating Disorder Characterized by Binge Eating and Purging
Bulimia nervosa is a type of eating disorder that involves recurrent episodes of binge eating followed by purging behaviors such as self-induced vomiting, misuse of laxatives or diuretics, fasting, or excessive exercise. The DSM 5 diagnostic criteria for bulimia nervosa include recurrent episodes of binge eating, a sense of lack of control over eating during the episode, and recurrent inappropriate compensatory behaviors to prevent weight gain. These behaviors occur at least once a week for three months and are accompanied by an undue influence of body shape and weight on self-evaluation.
Management of bulimia nervosa involves referral for specialist care and the use of bulimia-nervosa-focused guided self-help or individual eating-disorder-focused cognitive behavioral therapy (CBT-ED). Children should be offered bulimia-nervosa-focused family therapy (FT-BN). While pharmacological treatments have a limited role, a trial of high-dose fluoxetine is currently licensed for bulimia. It is important to seek appropriate care for bulimia nervosa to prevent the physical and psychological consequences of this eating disorder.

A 60-year-old man is admitted from the angiography suite after the cardiologist discovered severe triple vessel disease. He awaits transfer to a tertiary hospital for a coronary artery bypass graft. After 48 hours of admission, you receive a call to see him as he has become confused, sweaty, tremulous, and agitated.
Upon reviewing his record, you note a history of asthma, variceal bleed, and cirrhosis secondary to alcohol excess. His observations show a pyrexia at 37.9ºC, heart rate of 105 bpm, and blood pressure 175/98 mmHg. What would be the most appropriate immediate intervention given the likely diagnosis?Your Answer: Pabrinex
Correct Answer: Chlordiazepoxide
Explanation:Chlordiazepoxide or diazepam are effective treatments for delirium tremens and alcohol withdrawal. Symptoms of alcohol withdrawal can include confusion, agitation, tremors, hallucinations, and autonomic dysfunction such as high blood pressure, sweating, and fever.
Chlordiazepoxide is the most appropriate answer for this scenario. While confusion, sweating, and agitation can be signs of infection, the patient’s alcohol history suggests that delirium tremens is the more likely diagnosis. IV antibiotics would not address the primary issue of alcohol withdrawal. The patient’s high blood pressure also suggests that infection is not the cause of their symptoms.
Intravenous hydration may be necessary if the patient is experiencing excessive fluid loss due to sweating, but it would not be the best treatment for alcohol withdrawal in this case.
Alcohol withdrawal occurs when an individual who has been consuming alcohol chronically suddenly stops or reduces their intake. Chronic alcohol consumption enhances the inhibitory effects of GABA in the central nervous system, similar to benzodiazepines, and inhibits NMDA-type glutamate receptors. However, alcohol withdrawal leads to the opposite effect, resulting in decreased inhibitory GABA and increased NMDA glutamate transmission. Symptoms of alcohol withdrawal typically start at 6-12 hours and include tremors, sweating, tachycardia, and anxiety. Seizures are most likely to occur at 36 hours, while delirium tremens, which includes coarse tremors, confusion, delusions, auditory and visual hallucinations, fever, and tachycardia, peak at 48-72 hours.
Patients with a history of complex withdrawals from alcohol, such as delirium tremens, seizures, or blackouts, should be admitted to the hospital for monitoring until their withdrawals stabilize. The first-line treatment for alcohol withdrawal is long-acting benzodiazepines, such as chlordiazepoxide or diazepam, which are typically given as part of a reducing dose protocol. Lorazepam may be preferable in patients with hepatic failure. Carbamazepine is also effective in treating alcohol withdrawal, while phenytoin is said to be less effective in treating alcohol withdrawal seizures.

Sarah, a 44-year-old taxi driver, visits her GP 4 months after being involved in a car accident. During the consultation, the GP takes a thorough psychiatric history. Sarah is unable to recall the specifics of the accident, but the thought of driving her car causes her to feel anxious. Consequently, she avoids driving whenever possible, which worries her as it may impact her income.
Further investigation by the GP reveals that Sarah has been compulsively buying clothes and electronics online. Additionally, she has been relying on her sister and son to help with household tasks such as cooking and cleaning due to a lack of motivation. Sarah's sister has also noted that she has been crossing busy roads recklessly on several occasions.
Which aspect of Sarah's history provides the strongest indication of a PTSD diagnosis?Your Answer: Avoidance of driving
Explanation:PTSD is characterized by several common features, including re-experiencing of the traumatic event through flashbacks and nightmares, avoidance of triggering situations or people, and hyperarousal such as hypervigilance and sleep disturbances. Those with PTSD may avoid situations that cause anxiety related to the traumatic event, as well as certain individuals or objects. While disordered mood and thinking are present in PTSD, individuals with the disorder often remember specific details of the traumatic event in vivid detail. Compulsive behavior is not a recognized symptom of PTSD, but may be present in other psychiatric conditions such as bipolar disorder. While increased reliance on family members is not a recognized feature of PTSD, individuals with the disorder may experience difficulties in relationships and interpersonal interactions.
Understanding Post-Traumatic Stress Disorder (PTSD)
Post-traumatic stress disorder (PTSD) is a mental health condition that can develop in individuals of any age following a traumatic event. This can include experiences such as natural disasters, accidents, or even childhood abuse. PTSD is characterized by a range of symptoms, including re-experiencing the traumatic event through flashbacks or nightmares, avoidance of situations or people associated with the event, hyperarousal, emotional numbing, depression, and even substance abuse.
Effective management of PTSD involves a range of interventions, depending on the severity of the symptoms. Single-session interventions are not recommended, and watchful waiting may be used for mild symptoms lasting less than four weeks. Military personnel have access to treatment provided by the armed forces, while trauma-focused cognitive behavioral therapy (CBT) or eye movement desensitization and reprocessing (EMDR) therapy may be used in more severe cases.
It is important to note that drug treatments for PTSD should not be used as a routine first-line treatment for adults. If drug treatment is used, venlafaxine or a selective serotonin reuptake inhibitor (SSRI), such as sertraline, should be tried. In severe cases, NICE recommends that risperidone may be used. Overall, understanding the symptoms and effective management of PTSD is crucial in supporting individuals who have experienced traumatic events.

A 42-year-old man comes to the Emergency Department claiming that he is infested with fleas. He reports feeling extremely itchy and is requesting treatment. This is his fourth visit in the past year for this issue. The patient has no notable medical history and denies using any illicit drugs. He drinks 12 units of alcohol per week and is employed full-time as a teacher.
What is the probable diagnosis?Your Answer: Delusional parasitosis
Explanation:The correct diagnosis for a patient who has a fixed, false belief that they are infested by bugs is delusional parasitosis. This rare condition can occur on its own or alongside other psychiatric disorders, but typically does not significantly impair the patient’s daily functioning. Capgras syndrome, delirium tremens, and Fregoli syndrome are all incorrect diagnoses for this particular case.
Understanding Delusional Parasitosis
Delusional parasitosis is a condition that is not commonly known but can be debilitating for those who suffer from it. It is characterized by a persistent and false belief that one is infested with bugs, parasites, mites, bacteria, or fungus. This delusion can occur on its own or in conjunction with other psychiatric conditions. Despite the delusion, patients may still be able to function normally in other aspects of their lives.
In simpler terms, delusional parasitosis is a rare condition where a person believes they have bugs or other organisms living on or inside their body, even though there is no evidence to support this belief. This can cause significant distress and anxiety for the individual, and they may go to great lengths to try and rid themselves of the perceived infestation. It is important for those who suspect they may be suffering from delusional parasitosis to seek professional help, as treatment can greatly improve their quality of life.

You are about to prescribe fluoxetine, a selective serotonin reuptake inhibitor (SSRI) to a 50-year-old man who has just started a new relationship. He asks about common side-effects.
Which of the below is a common side-effect that it would be most important to council this patient about?Your Answer: Sexual dysfunction
Explanation:Understanding the Side-Effects of SSRIs: Sexual Dysfunction, Constipation, Sedation, Urinary Retention, and Dry Mouth
Selective serotonin reuptake inhibitors (SSRIs) are commonly prescribed for major depressive and generalized anxiety disorders. These drugs work by increasing serotonin concentration in the synaptic cleft, which stimulates post-synaptic neurons and improves mood. However, SSRIs can also cause several side-effects that patients should be aware of.
One of the most important side-effects to keep in mind is sexual dysfunction. Patients may feel uncomfortable discussing this issue, so it is important for healthcare providers to ask about it specifically. Sildenafil can be useful in treating this side-effect.
SSRIs can also cause gastrointestinal upset, including dyspepsia, nausea, abdominal pain, diarrhea, and constipation. However, given the patient’s age, it would be most appropriate to counsel regarding sexual dysfunction.
While SSRIs are associated with insomnia, restlessness, and general agitation, they are not typically associated with sedation. Urinary disorders can be associated with SSRIs, but they are more commonly seen with the use of tricyclic antidepressants. Dry mouth is a common side-effect of SSRIs, but it is less important to counsel patients about than sexual dysfunction.
In summary, patients taking SSRIs should be aware of the potential side-effects, including sexual dysfunction, gastrointestinal upset, insomnia, urinary disorders, and dry mouth. Healthcare providers should ask about sexual dysfunction specifically and provide appropriate treatment options.

A young man arrives at the emergency department after taking a paracetamol overdose following a recent break-up. He has since entered into a new relationship, but is struggling with frequent outbursts of anger. The patient has a history of childhood abuse and struggles with maintaining healthy relationships. He reports experiencing frequent mood swings between low and elevated states. The overdose was not premeditated and the patient has a history of similar incidents. What is the most probable diagnosis?
Your Answer: Bipolar affective disorder
Correct Answer: Borderline personality disorder
Explanation:The young woman who overdosed on paracetamol after breaking up with her boyfriend is now in a new relationship, but it is troubled by her frequent outbursts of anger. These symptoms suggest that she may be suffering from borderline personality disorder, which is characterized by intense and rapidly changing emotions, difficulties with relationships, feelings of emptiness, fear of abandonment, impulsive behavior, and self-harm. Bipolar affective disorder, dependent personality disorder, and histrionic personality disorder are not likely diagnoses based on the information provided.
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 16
Correct
-
A 17-year-old male student spontaneously disrobed while watching a film. He saw wavy lines on the screen and then reported a brief episode of mental blankness, followed soon after by a headache and extreme fatigue.
What is the most likely diagnosis?Your Answer: Partial complex seizure or Focal Impaired Awareness epilepsy
Explanation:Neuropsychiatric Syndromes and Seizure Disorders: Understanding the Differences
Seizure disorders can be complex and varied, with different symptoms and causes. One type of seizure disorder is the partial complex seizure (PCS), which is confined to the limbic structures of the brain. Symptoms of PCS can include visual distortions and disruptions of cognitive function. Patients may also experience intense dysphoria, anxiety, or rage during or after a seizure. However, organised, directed violent behaviour is not typical of a seizure.
Another type of seizure disorder is the generalised tonic-clonic epilepsy, which can cause a loss of consciousness and convulsions. Inhibition-type behaviour is not typical of this disorder, and there is no history of tonic-clonic seizure activity.
Schizophreniform disorder is a condition that involves schizophrenic symptoms of short duration. Patients with repeated focal seizures may exhibit personality changes that closely resemble chronic schizophrenia, such as passivity, unusual sexual behaviour, anhedonia, obsessiveness, religiosity, and psychosis.
Migraine behavioural syndrome can involve visual auras, but it is unlikely to involve bizarre behaviour such as inappropriate disrobing. Finally, exhibitionism involves attracting attention to oneself, such as compulsive exposure of genitals in public.
Understanding the differences between these neuropsychiatric syndromes and seizure disorders is important for accurate diagnosis and treatment.

A 25-year-old man with Down syndrome is brought to see the General Practitioner (GP) by his mother to discuss his acne. His mother takes care of all his medications, as he cannot understand the instructions. He lives with his parents and depends on them to do all his cooking and washing. He does not work but attends a day centre a few days per week, where he enjoys craft activities and has a number of close friends. The staff report he is always very polite and interacts well with everyone at the centre. His mother says he is unable to be left alone in the house and cannot go out on his own without the support of another adult.
Which one of the following conditions does he have?Your Answer: Learning disability
Explanation:The patient is unable to function independently and relies on his parents for daily care, indicating a possible diagnosis of a learning disability. This condition is defined by the Department of Health as a significant reduction in the ability to learn new skills and understand complex information, leading to a decreased ability to cope independently. Symptoms must have started before adulthood and have a lasting impact on development. Other potential diagnoses, such as ADHD, autism spectrum disorder, learning difficulty, and oppositional defiant disorder, do not fit the patient’s symptoms and behaviors.

A young adult is concerned about her ability to take her upcoming final exams at university in three months. She experiences feelings of fluster, faintness, and dizziness specifically during written exams, but has no symptoms at any other time, including during physical activity. Her resting ECG is normal and clinical examination shows no abnormalities. What is the best course of action to take?
Your Answer: Arrange counselling, with relaxation training
Explanation:a Student’s Symptoms of Stress and Anxiety
The symptoms described by the student are typical of stress and anxiety, which are common experiences for many people. It is important to reassure the student that these symptoms do not necessarily indicate an underlying medical condition. However, if the student is concerned, a 24-hour ECG monitoring can be done to provide further reassurance.
It is important to note that prescribing diazepam may not be the best course of action as it can impair the student’s exam performance. Similarly, fluoxetine may not be the best option as it can increase feelings of anxiety. It is important to consider alternative treatments that can help the student manage their stress and anxiety in a way that does not negatively impact their academic performance. By the student’s symptoms and providing appropriate support, we can help them navigate this challenging time and achieve their academic goals.

Samantha is a 38-year-old female who has come to the crisis team with suicidal thoughts. Upon further inquiry, Samantha also reveals experiencing low mood, lack of energy, early morning awakenings, and difficulty concentrating. She reports that these symptoms are persistent, but she has both good and bad days. Samantha has no prior psychiatric history. What medication would be the most suitable to initiate treatment for Samantha?
Your Answer: Sertraline
Explanation:When managing a patient with depression, it is important to consider several factors according to NICE guidelines. These include managing suicide risk, safeguarding concerns for vulnerable individuals, and any comorbid conditions such as substance abuse. If the patient exhibits psychotic symptoms or eating disorders, seeking expert advice is recommended. For those with mild depression or subthreshold symptoms, active monitoring and follow-up appointments are suggested. Psychological interventions through IAPT are recommended for persistent subthreshold or mild-to-moderate depression, while antidepressants and high-intensity psychological interventions are recommended for moderate or severe depression. When prescribing antidepressants, it is important to consider the patient’s history and any chronic physical health problems, with sertraline being preferred in such cases due to its lower risk of drug interactions. Practical solutions to stressors contributing to depression should also be discussed.
In 2022, NICE updated its guidelines on managing depression and now classifies it as either less severe or more severe based on a patient’s PHQ-9 score. For less severe depression, NICE recommends discussing treatment options with patients and considering the least intrusive and resource-intensive treatment first. Antidepressant medication should not be routinely offered as first-line treatment unless it is the patient’s preference. Treatment options for less severe depression include guided self-help, group cognitive behavioral therapy, group behavioral activation, individual CBT or BA, group exercise, group mindfulness and meditation, interpersonal psychotherapy, SSRIs, counseling, and short-term psychodynamic psychotherapy. For more severe depression, NICE recommends a shared decision-making approach and suggests a combination of individual CBT and an antidepressant as the preferred treatment option. Other treatment options for more severe depression include individual CBT or BA, antidepressant medication, individual problem-solving, counseling, short-term psychodynamic psychotherapy, interpersonal psychotherapy, guided self-help, and group exercise.

Question 20
Correct

A 28-year-old male patient visits the psychiatric clinic for a routine check-up. He reports experiencing weight gain, erectile dysfunction, and gynaecomastia. The patient was diagnosed with schizophrenia a year ago and has been struggling to find a suitable medication despite being compliant. He expresses concern that his partner is becoming increasingly frustrated with his lack of sexual interest, which is affecting their relationship. What is the most appropriate management option for this case?
Your Answer: Switch to aripiprazole
Explanation:The best course of action for this patient, who has been diagnosed with schizophrenia and is experiencing side effects such as gynaecomastia, loss of libido and erectile dysfunction, is to switch to aripiprazole. This medication has the most tolerable side effect profile of the atypical antipsychotics, particularly when it comes to prolactin elevation, which is likely causing the patient’s current symptoms. It is important to find a medication that reduces side effects, and aripiprazole has been shown to do so. Options such as once-monthly intramuscular antipsychotic depo injections are more suitable for patients who struggle with compliance, which is not the case for this patient. Switching to clozapine or haloperidol would not be appropriate due to their respective side effect profiles.
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 young man seeks counselling because of marital discord. He and his wife have been having problems because he is uninterested in doing anything but playing video games. He has neglected his responsibilities at home and his work performance is beginning to suffer as well.
Which one of the following best describes his behaviour?Your Answer: Fixation
Explanation:Defense Mechanisms: Understanding Fixation, Dissociation, Sublimation, Reaction Formation, and Splitting
Defense mechanisms are psychological strategies that individuals use to cope with difficult situations or emotions. Here are some common defense mechanisms and their explanations:
Fixation: This occurs when a person becomes stuck in a particular stage of development and fails to progress. For example, someone who is fixated on football may prioritize it over other aspects of their life, leading to an imbalance.
Dissociation: This is a defense mechanism where a person temporarily disconnects from their thoughts, feelings, or memories to avoid distress. In extreme cases, dissociation can lead to dissociative identity disorder.
Sublimation: This is a mature defense mechanism where a person channels an unacceptable trait or desire into a socially acceptable behavior. For example, someone with aggressive tendencies may become a successful athlete.
Reaction Formation: This is an immature defense mechanism where a person represses unacceptable emotions and replaces them with their opposite. For instance, someone with repressed homosexual desires may become an outspoken advocate against homosexuality.
Splitting: This is a defense mechanism where a person sees others as either all good or all bad, unable to reconcile both positive and negative traits. For example, someone who experiences a bad breakup may only see their ex-partner as a terrible person, ignoring any positive qualities they may have had.
Understanding these defense mechanisms can help individuals recognize and address unhealthy patterns in their behavior and emotions.

A 27-year-old is brought to the on-call psychiatry team at a hospital after being found wandering aimlessly on the streets. The patient had a breakdown in a local convenience store where they were caught stealing cigarettes and had a violent outburst when confronted by the store clerk. When asked about their behavior, they state that they do not care about the consequences of their actions and that they have stolen many times before. They also admit to enjoying hurting others in the past and have a history of animal cruelty. Although they report self-harming in the past, there are no visible scars.
Which of the following characteristics would be more indicative of a diagnosis of antisocial personality disorder rather than borderline personality disorder?Your Answer: Male gender
Explanation:Men are more commonly affected by antisocial personality disorder, while borderline personality disorder is more frequently diagnosed in young women. However, there can be some overlap in the symptoms of both disorders, such as impulsivity. Borderline personality disorder is characterized by unstable emotions, fluctuating self-image, and recurrent thoughts of self-harm or suicide. On the other hand, antisocial personality disorder is marked by a repeated failure to follow social norms or rules, reckless behavior that endangers oneself and others, and a lack of remorse for these actions. If there are persistent mood changes or psychotic symptoms present, it may indicate a different primary diagnosis than a personality disorder.
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.

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.

A 72-year-old patient comes to see the General Practitioner with his daughter. She expresses concern that her father has been acting differently lately. Once the daughter leaves the room, he confides in the doctor that the woman who came with him is not his daughter, but an imposter. He firmly believes this and cannot be convinced otherwise.
What is the most probable diagnosis?Your Answer: Capgras syndrome
Explanation:Different Types of Delusional Disorders
Delusional disorders are a group of mental illnesses characterized by false beliefs that persist despite evidence to the contrary. Here are some of the different types of delusional disorders:
1. Capgras syndrome: Patients believe that a loved one has been replaced by an exact double.
2. Cotard syndrome: Patients have nihilistic delusions, such as believing that they or parts of their body are dead or decaying.
3. Othello syndrome: Patients believe that their partner is cheating on them, despite no proof.
4. De Clerambault syndrome: Patients believe that someone famous is deeply in love with them.
It is important to note that these disorders are rare and require professional diagnosis and treatment.

A 38-year-old man presents to the Emergency Department complaining of epigastric pain. The patient reports that he developed acute abdominal pain 2 hours prior to presentation after eating a cheeseburger. The patient otherwise has no significant past medical history. He does not take any medications and denies smoking, alcohol consumption and drug use. He has been recently been released from prison and has not got stable living and has had to sleep outside since his release.
On examination, the patient has normal vital signs. His abdominal examination demonstrates normoactive bowel sounds, no tenderness to palpation in the epigastrium and no guarding or rebound tenderness. Rectal exam for stool occult blood is negative and a chest X-ray does not reveal free air under the diaphragm. A right upper quadrant ultrasound does not demonstrate stones. The doctor recommends antacids. When the doctor tells the patient that he is safe for discharge, the patient insists that he must be admitted to hospital for further tests.
Which of the following is the most likely diagnosis?Your Answer: Hypochondriasis
Correct Answer: Malingering
Explanation:Differentiating between Malingering, Factitious Disorder, Conversion Disorder, and Hypochondriasis
When a patient presents with physical symptoms but there are no physical or imaging signs of significant illness, the likely diagnosis is malingering. In such cases, it is important to investigate the patient’s history to see if there could be other factors impacting their symptoms. Malingering is often suspected when a patient insists on staying in the hospital despite negative test results.
Factitious disorder refers to a patient who assumes the sick role without any physical or organic disease. These patients find satisfaction in being taken care of and often seek frequent outpatient visits and psychotherapy.
Factitious or induced illness is similar to factitious disorder, but it involves a patient seeking the sick role vicariously through a second patient. For example, a mother suffering from factitious disorder may abuse her child so that she can bring the child to the doctor for treatment. The patient assumes the sick role by proxy through the child.
Conversion disorder refers to the manifestation of psychological illness as neurologic pathology. Patients with conversion disorder suffer from symptoms such as weakness, numbness, blindness, or paralysis as a result of underlying psychiatric illness. They are often not bothered by their symptoms, a condition known as la belle indifférence.
Hypochondriasis refers to the fear of having a medical illness despite negative tests and reassurance. It is not associated with secondary gain.

A 35-year-old male with a history of daily alcohol consumption for the last five years is admitted to the hospital emergency room. He is experiencing acute visual hallucinations, seeing spiders all around him, and is unable to recognize his family members. He is also exhibiting aggressive behavior and tremors. The patient had stopped drinking alcohol for two days prior to admission. On examination, he has a blood pressure of 170/100 mmHg, tremors, increased psychomotor activity, fearful affect, hallucinatory behavior, disorientation, impaired judgment, and insight. What is the most likely diagnosis?
Your Answer: Korsakoff's psychosis
Correct Answer: Delirium tremens
Explanation:Delirium Tremens
Delirium tremens (DT) is a severe and potentially life-threatening condition that can occur when someone abruptly stops drinking alcohol. Symptoms can begin within a few hours of cessation, but they may not peak until 48-72 hours later. The symptoms of DT can include tremors, irritability, insomnia, nausea and vomiting, hallucinations (auditory, visual, or olfactory), confusion, delusions, severe agitation, and seizures. Physical findings may be non-specific and include tachycardia, hyperthermia, hypertension, tachypnea, diaphoresis, tremor, mydriasis, ataxia, altered mental status, hallucinations, and cardiovascular collapse.
It is important to note that not everyone who stops drinking alcohol will experience DT. However, those who have a history of heavy alcohol use or have experienced withdrawal symptoms in the past are at a higher risk. DT can be a medical emergency and requires immediate treatment.

A 78-year-old man with known dementia is admitted to hospital for treatment of a community acquired pneumonia. Unfortunately, he was not accompanied by a family member and the history provided by the patient seems confused. Upon arrival of the daughter, she confirms that her father has been confusing real events with those from his imagination. Through this process he appears to be able to maintain a superficial conversation despite significant cognitive impairment.
Which of the following describes this phenomenon?Your Answer: Confabulation
Explanation:Differentiating Confabulation, Delusions, and Other Psychiatric Phenomena
Confabulation, delusions, and other psychiatric phenomena can be confusing and difficult to differentiate. Confabulation is a phenomenon where patients fabricate imaginary experiences due to memory loss, often seen in patients with cognitive impairment. Delusions, on the other hand, are beliefs held with strong conviction despite evidence to the contrary, commonly seen in conditions such as schizophrenia. Flight of ideas, pressure of speech, and hallucinations are other psychiatric phenomena that can be seen in different conditions. Understanding the differences between these phenomena is crucial in making accurate diagnoses and providing appropriate treatment.

A 25-year-old male is brought to the emergency department by his friends who are concerned about his behavior. The patient's friends report that over the past few days the patient has hardly slept or eaten and is talking non-stop about a new business idea that he believes will make him a millionaire. He has also been spending a lot of money on his credit card and started making impulsive purchases. During the interview, the emergency department doctor observes that the patient is speaking rapidly and is difficult to interrupt. Despite the speed of his speech, the words themselves are coherent and follow a logical, albeit unusual, pattern of thought.
What is the most appropriate term to describe the patient's abnormal speech pattern?Your Answer: Pressured speech
Explanation:Mania and Related Speech Patterns
Mania is a mental state characterized by elevated mood, energy, and activity levels. A patient presenting with decreased need for sleep, increased risk-taking behavior, and delusions of grandeur may be exhibiting symptoms of mania. One common speech pattern associated with mania is pressured speech, which is characterized by rapid speech that is difficult to interrupt.
Other speech patterns that may be observed in patients with mania include clanging, echolalia, neologism, and word salad. Clanging refers to the use of rhyming words, while echolalia involves repeating what the examiner says. Neologism refers to the creation of new words, and word salad is a completely disorganized speech that is not understandable.
It is important for healthcare professionals to recognize these speech patterns and other symptoms of mania in order to provide appropriate treatment and support for patients. By the characteristics of mania and related speech patterns, healthcare professionals can help patients manage their symptoms and improve their overall quality of life.

Sarah is a 35-year-old married woman with two children. She comes to you in distress and expresses suicidal thoughts, stating that she has considered taking an overdose. She has no history of self-harm or suicide attempts, and no psychiatric background. Despite having a loving family and enjoying her job, she is struggling. What is a risk factor for suicide in this case?
Your Answer: First presentation to mental health services
Correct Answer: Male gender
Explanation:Suicide Risk Factors and Protective Factors
Suicide risk assessment is a common practice in psychiatric care, with patients being stratified into high, medium, or low risk categories. However, there is a lack of evidence on the positive predictive value of individual risk factors. A review in the BMJ concluded that such assessments may not be useful in guiding decision-making, as 50% of suicides occur in patients deemed low risk. Nevertheless, certain factors have been associated with an increased risk of suicide, including male sex, history of deliberate self-harm, alcohol or drug misuse, mental illness, depression, schizophrenia, chronic disease, advancing age, unemployment or social isolation, and being unmarried, divorced, or widowed.
If a patient has attempted suicide, there are additional risk factors to consider, such as efforts to avoid discovery, planning, leaving a written note, final acts such as sorting out finances, and using a violent method. On the other hand, there are protective factors that can reduce the risk of suicide, such as family support, having children at home, and religious belief. It is important to consider both risk and protective factors when assessing suicide risk and developing a treatment plan.

A 58-year-old woman with a long history of bipolar disorder visits the mental health clinic. She reports experiencing an uncomfortable sensation of inner restlessness for several months, and her husband observes that she frequently moves her arms and legs.
What symptom is the woman experiencing?Your Answer: Akathisia
Explanation:Akathisia is characterized by an inner sense of restlessness and an inability to remain still. It is commonly observed in individuals with a prolonged history of anti-psychotic medication use, often due to schizophrenia. Symptoms of acute dystonia typically involve spasms of facial muscles, while parkinsonism may manifest as changes in gait and resting tremors. Tardive dyskinesia is characterized by abnormal involuntary movements, such as lip-licking. Although rare in individuals who have been on anti-psychotics for an extended period, neuroleptic malignant syndrome may present with hyperthermia and muscle rigidity.
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.

He is speaking rapidly, claiming to be the ‘new Messiah’ and insisting that he has the ability to cure acquired immune deficiency syndrome (AIDS) with the assistance of his friends who are providing him with undisclosed 'classified' knowledge.
What medication would be appropriate to administer to this individual?Your Answer: Olanzapine
Explanation:Choosing the Right Medication for Psychosis: A Comparison of Olanzapine, Diazepam, Citalopram, Clozapine, and Zopiclone
When a patient presents with psychosis, it is crucial to assess them urgently and rule out any organic medical causes. The primary treatment for psychosis is antipsychotics, such as olanzapine. While benzodiazepines like diazepam can be used to treat agitation associated with acute psychosis, they are not the first-line treatment. Citalopram, a selective serotonin reuptake inhibitor used for depression, would not be appropriate for treating psychosis. Clozapine, another antipsychotic, is only used on specialist advice due to the risk of agranulocytosis. Zopiclone, a hypnotic used for sleep, is not appropriate for treating psychosis. It is important to choose the right medication for psychosis to ensure the best possible outcome for the patient.
