A 35-year-old woman arrives at the emergency department with symptoms of restlessness and confusion that have been present for one day. Upon further examination, she is found to have an elevated heart rate and body temperature. The patient has a history of depression and has been taking sertraline for several years without any changes in dosage or overdose incidents. However, her partner reports that she was recently prescribed a new medication by her general practitioner, which may have interacted with her regular medication. What is the most likely medication responsible for this interaction?
Your Answer: Oral combined contraceptive pill
Correct Answer: Zolmitriptan
Explanation:Patients who are taking a SSRI should not use triptans.
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 65-year-old male has been admitted to the in-patient psychiatric unit. Upon review this morning, he appears to be a poor historian, providing minimal answers and insisting that he is deceased and does not belong in a hospital meant for the living. What is the specific name of this delusional disorder and with which condition is it typically linked?
Your Answer: Cotard syndrome and Major Depressive Disorder
Explanation:Severe depression is often linked to Cotard syndrome, a rare form of nihilistic delusions where individuals believe they are dead or non-existent. This condition can also be observed in individuals with schizophrenia.
Understanding Cotard Syndrome
Cotard syndrome is a mental disorder that is characterized by the belief that the affected person or a part of their body is dead or non-existent. This rare condition is often associated with severe depression and psychotic disorders, making it difficult to treat. Patients with Cotard syndrome may stop eating or drinking as they believe it is unnecessary, leading to significant health problems.
The delusion experienced by those with Cotard syndrome can be challenging to manage, and it can have a significant impact on their quality of life. The condition is often accompanied by feelings of hopelessness and despair, which can make it challenging for patients to seek help. Treatment for Cotard syndrome typically involves a combination of medication and therapy, but it can take time to find an effective approach.

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

Question 4

A 65-year-old man is brought to the doctors by his son. Three weeks ago his wife passed away from metastatic breast cancer. He reports feeling sad and tearful every day, but his son is worried because he keeps getting into arguments with him over small things and bringing up past family issues. The son also mentions that his father has mentioned hearing his wife's voice and even cooked a meal for her once. Despite this, he has started going for walks with his friends again and is determined to get his life back on track. What is the most probable diagnosis?
Your Answer: Normal grief reaction
Explanation:Grief is a natural response to the death of a loved one and does not always require medical intervention. However, understanding the potential stages of grief can help determine if a patient is experiencing a normal reaction or a more significant problem. The most common model of grief divides it into five stages: denial, anger, bargaining, depression, and acceptance. It is important to note that not all patients will experience all five stages. Atypical grief reactions are more likely to occur in women, sudden and unexpected deaths, problematic relationships before death, and lack of social support. Delayed grief, which occurs when grieving does not begin for more than two weeks, and prolonged grief, which is difficult to define but may last beyond 12 months, are features of atypical grief reactions.

A 22-year-old man with a history of hearing voices is brought to the Emergency Department by his family. He describes these voices as telling him to kill himself, ‘as he has a demon in him’. He also reports noting his intelligence being tapped through the television by a higher power. This has been going on for the past 3 months. His family denies either depression or manic episodes. The patient was admitted to the inpatient Psychiatry Unit and, after an evaluation, a diagnosis of schizophreniform disorder was made. He was started on Haldol (haloperidol) for his symptoms. Two days after initiation of therapy, the patient’s temperature rose to 41 °C, blood pressure 150/85 mmHg and pulse 110 bpm. Physical examination revealed muscular rigidity and delirium.
What is the most likely diagnosis?Your Answer: Serotonin syndrome
Correct Answer: Neuroleptic malignant syndrome
Explanation:Understanding Neurological Disorders Caused by Medications
Neurological disorders can be caused by certain medications, such as high-potency anti-psychotic drugs like haloperidol. One such disorder is neuroleptic malignant syndrome, which can result from the use of these medications to treat conditions like schizophrenia. Symptoms include muscular rigidity, fever, and altered mental status. Treatment involves discontinuing the medication and managing symptoms with cooling measures and medications like dantrolene or bromocriptine.
Another medication-induced neurological disorder is serotonin syndrome, which can occur when a patient takes multiple doses or an overdose of medications like selective serotonin reuptake inhibitors (SSRIs) or serotonin agonists. Symptoms include muscular twitching, agitation, and autonomic instability. Treatment involves discontinuing the medication and managing symptoms with supportive care.
Malignant hyperthermia is a similar disorder that can occur during anesthesia administration and is caused by an inherited genetic disorder. Symptoms include fever, muscle rigidity, and altered mental status. Treatment involves using medications like dantrolene and providing supportive care.
It’s important to note that not all neurological disorders are caused by medications. Meningitis, for example, is not a side effect of haloperidol. Acute dystonia, which presents with spasms of various muscle groups, can also be caused by haloperidol, but the presenting symptoms are more consistent with neuroleptic malignant syndrome. Understanding the different neurological disorders caused by medications can help healthcare providers make accurate diagnoses and provide appropriate treatment.

Question 6
Correct

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

You speak to the husband of a patient with depression who was recently discharged from a psychiatry ward after a suicide attempt. He was switched from sertraline to venlafaxine. His husband says his mood is okay but over the last 2 weeks, he became erratic and was not sleeping. He spoke fast about a 'handsome inheritance' he got but was gambling away their savings saying he was going to save the world. When confronted he became angry and accused him of trying to 'steal his energy'. You suspect he's developed mania and refer him to the crisis psychiatry team.
What do you anticipate will be the subsequent step in management?Your Answer: Cross-taper the patient to mirtazapine and add sodium valproate modified-release
Correct Answer: Stop venlafaxine and start risperidone
Explanation:When managing a patient with mania or hypomania who is taking antidepressants, it is important to consider stopping the antidepressant and starting antipsychotic therapy. In this case, the correct course of action would be to stop venlafaxine and start risperidone. Antidepressants can trigger mania or hypomania as a side effect, particularly with SSRIs and TCAs, and venlafaxine has a particularly high risk. NICE guidance recommends stopping the antidepressant and offering an antipsychotic, with haloperidol, olanzapine, quetiapine, or risperidone as options. Cross-tapering the patient back to sertraline or mirtazapine and adding sodium valproate modified-release is not recommended. Prescribing a two-week course of oral clonazepam is also not recommended due to the risk of overdose. Starting lithium is not recommended as first-line for the management of acute mania in patients who are not already on antipsychotics.
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 45-year-old woman presents to the Outpatient clinic with complaints of involuntary muscle movements of her tongue, fingers and trunk for the past 2 months. She was diagnosed with schizophrenia 10 years ago and has been on flupenthixol and then haloperidol, with good compliance. On examination, her temperature is 37.7 °C, blood pressure 115/80 mmHg and pulse 92 bpm. Her respiratory rate is 14 cycles/min. There is pronounced choreoathetoid movement of the hand and fingers.
What is the next line of management of this patient?Your Answer: Stop the haloperidol and start chlorpromazine
Correct Answer: Stop the haloperidol and start olanzapine
Explanation:Treatment options for extrapyramidal side-effects of anti-psychotic medication
Extrapyramidal side-effects are common with anti-psychotic medication, particularly with typical anti-psychotics such as haloperidol and chlorpromazine. Tardive dyskinesia is one such side-effect, which can be treated by switching to an atypical anti-psychotic medication like olanzapine. Acute dystonia, on the other hand, can be managed with anticholinergics. Decreasing the dose of haloperidol can help alleviate akathisia, or motor restlessness. Supportive therapy is not effective in treating extrapyramidal side-effects. It is important to monitor patients for these side-effects and adjust medication accordingly to ensure optimal treatment outcomes.

A 25-year-old man with type I diabetes mellitus visits his General Practitioner (GP) with concerns about his deteriorating glycaemic control. The GP suspects poor compliance with diet and medication. What is the most effective approach to enhance his compliance during a brief consultation?
Your Answer: Self-help materials
Correct Answer: Motivational interview
Explanation:Effective Psychological Interventions in Primary Care
Primary care settings are often the first point of contact for patients seeking help for mental health or physical conditions. To provide effective care, healthcare professionals can employ various psychological interventions. Here are some of the most effective ones:
Motivational Interviewing: This patient-centred approach involves resisting a didactic course of action, understanding the reasons for the change in behaviour, listening to the patient’s ideas, concerns or expectations, and empowering the patient to understand they are able to change their behaviour. It has been proven to increase compliance with medication.
Cognitive Behavioural Therapy (CBT): This talking therapy explores the patient’s understanding, concepts and reactions towards a certain problem, gradually building behavioural changes to challenge the concepts and manage the problem. It is used predominantly in the treatment of anxiety and depression, but can also be employed in many other mental health or physical conditions.
Self-Help Materials: Self-help materials in the form of leaflets and aids are a useful tool in the primary care setting, but the patient needs to be motivated for change in order for these to work.
Psychotherapy: This form of counselling employs various techniques to induce behavioural changes and habits that will stay with the patient in the long term. This requires a set amount of sessions over a period of time and therefore, cannot be performed in a short consultation.
Supportive Counselling: This psychological intervention has been shown to be best suited for treating mild to moderate depression and can be used in combination with other methods such as CBT.
By employing these psychological interventions, healthcare professionals can provide effective care for patients seeking help for mental health or physical conditions in primary care settings.

A 67-year-old Indigenous male with a lengthy history of heavy alcohol use is hospitalized after experiencing a seizure upon stopping alcohol consumption. The physician observes that the patient is experiencing memory difficulties, as evidenced by his detailed recollection of events from the previous day in the hospital that are completely different from what actually occurred. The patient does not appear to have any intention of deceiving the doctor.
What is the most appropriate term to describe the patient's abnormality?Your Answer: Thought blocking
Correct Answer: Confabulation
Explanation:Common Terms in Psychiatry
Confabulation is the act of unintentionally reporting false memories that seem plausible. This can occur in individuals with Alzheimer’s disease or Korsakoff syndrome. Concrete thinking is a type of thinking where a person has difficulty thinking abstractly and may interpret proverbs literally. Hallucinations are sensory experiences that are not caused by external stimuli. Thought blocking is when a person suddenly stops their train of thought. Thought insertion is a delusion where a person believes that their thoughts are being placed in their mind by an external force.
These terms are commonly used in psychiatry to describe various symptoms and conditions. It is important to understand their meanings in order to properly diagnose and treat patients. Confabulation and concrete thinking may be indicative of cognitive impairment, while hallucinations and delusions may be symptoms of a psychotic disorder. Thought blocking may occur in individuals with schizophrenia, while thought insertion may be a symptom of delusional disorder. By these terms, healthcare professionals can provide better care for their patients.
