Question 1
Incorrect
-
A 30-year-old female arrives at the Emergency Department complaining of eye pain and an unusual posture. During the examination, it is observed that her neck is fixed in a backward and lateral position, and her eyes are deviated upwards. She is unable to control her gaze. The patient has a history of paranoid schizophrenia and is currently taking olanzapine. What is the probable reason for her symptoms?
Your Answer: Tardive dyskinesia
Correct Answer: Acute dystonic reaction
Explanation:Antipsychotics have the potential to cause acute dystonic reactions, including oculogyric crises. Symptoms may also include jaw spasms and tongue protrusion. Treatment typically involves administering IV procyclidine and discontinuing the medication responsible for the reaction. Akathisia is another potential side effect, characterized by restlessness and an inability to sit still. Tardive dyskinesia is a long-term side effect that can develop after years of antipsychotic use, resulting in involuntary facial movements such as grimacing, tongue protrusion, and lip smacking. Parkinsonism is a term used to describe antipsychotic side effects that mimic Parkinson’s disease, such as bradykinesia, cogwheel rigidity, and a shuffling gait.
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 2
Correct
-
At her routine check-up, a 75 year old woman is discovered to have a serum sodium level of 128 mmol/L. Despite feeling fine and having no symptoms, which of the following medications could be responsible for her hyponatraemia?
Your Answer: Sertraline
Explanation:Hyponatraemia, a condition where there is low sodium levels in the blood, can be caused by various drugs that either increase the production or enhance the effects of antidiuretic hormone (ADH). Among these drugs, diuretics (especially thiazides), SSRIs, antipsychotics like haloperidol, nonsteroidal anti-inflammatories, and carbamazepine are the most commonly implicated. SSRIs, in particular, can trigger the release of ADH, leading to hyponatraemia within the first few weeks of treatment. However, this condition usually resolves within two weeks of discontinuing the drug. The risk of developing hyponatraemia is higher in older patients and those taking diuretics concomitantly with SSRIs.
Understanding the Side-Effects and Interactions of SSRIs
SSRIs, or selective serotonin reuptake inhibitors, are commonly prescribed antidepressants that can have various side-effects and interactions with other medications. The most common side-effect of SSRIs is gastrointestinal symptoms, and patients taking these medications are at an increased risk of gastrointestinal bleeding. To mitigate this risk, a proton pump inhibitor should be prescribed if the patient is also taking a NSAID. Hyponatraemia, or low sodium levels, can also occur with SSRIs, and patients should be vigilant for increased anxiety and agitation after starting treatment.
Fluoxetine and paroxetine have a higher propensity for drug interactions, and citalopram has been associated with dose-dependent QT interval prolongation. The Medicines and Healthcare products Regulatory Agency (MHRA) has advised that 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 has been reduced for certain patient populations.
SSRIs can also interact with other medications, such as NSAIDs, warfarin/heparin, aspirin, and triptans. It is important to review patients after starting antidepressant therapy and to gradually reduce the dose when stopping treatment to avoid discontinuation symptoms. These symptoms can include mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.
In summary, understanding the potential side-effects and interactions of SSRIs is crucial for safe and effective treatment of depression and other mental health conditions. Patients should be closely monitored and counseled on the risks and benefits of these medications.

Question 3
Correct
-
A 29-year-old woman comes to her doctor's office in a distressed state. Her 4-year-old daughter passed away a few weeks ago due to a car accident. During the consultation, she reveals that she is having trouble sleeping, cannot function normally, and experiences severe stomach cramps. She admits to having thoughts of wishing she had died instead of her daughter, but denies any current suicidal thoughts. She also mentions seeing her daughter sitting on the couch at home, but acknowledges that it is not real. What is the most likely condition she is suffering from?
Your Answer: Normal grief reaction
Explanation:Experiencing a grief reaction is common after a significant loss, and it can manifest with physical and psychological symptoms that can last up to six months. It can be challenging to differentiate between depression and a typical grief reaction since they share similar symptoms. However, a regular grief reaction typically lasts less than six months, while depression can persist for a more extended period. Although she has brief visual hallucinations, psychosis is an incorrect diagnosis since she does not exhibit any other indications.
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 young adult woman complains that her mother interferes in every aspect of her life and tries to control her. The woman no longer speaks to her parents or eats meals with them. The mother has increased her efforts to maintain control.
Which of the following conditions could arise from this situation?Your Answer: Dissociative identity disorder
Correct Answer: Anorexia nervosa
Explanation:Psychological Disorders and Family Dynamics
Family dynamics can play a role in the development of certain psychological disorders. Anorexia nervosa, for example, may be linked to attempts to regain control and self-esteem through food restriction and weight loss. Dissociative identity disorder, on the other hand, is associated with severe childhood trauma, particularly sexual abuse. Narcissistic personality disorder is characterised by exaggerated feelings of self-importance and a strong need for approval from others. Schizophrenia may be influenced by highly expressed emotions within the family. Separation anxiety disorder, however, does not seem to be present in the given vignette. Understanding the relationship between family dynamics and psychological disorders can aid in diagnosis and treatment.

Which of the following is linked to a favorable prognosis in individuals with schizophrenia?
Your Answer: Acute onset
Explanation:A poor prognosis is often linked to a gradual onset rather than an acute one.
Schizophrenia is a mental disorder that can have varying prognoses depending on certain factors. Some indicators associated with a poor prognosis include a strong family history of the disorder, a gradual onset of symptoms, a low IQ, a prodromal phase of social withdrawal, and a lack of an obvious precipitant. These factors can contribute to a more severe and chronic course of the illness, making it more difficult to manage and treat. It is important for individuals with schizophrenia and their loved ones to be aware of these indicators and seek appropriate treatment and support.

A patient with a history of depression at the age of 50 presents for review. What indicates an elevated risk of suicide?
Your Answer: History of arm cutting
Explanation:Arm cutting may be seen as attention-seeking or a way to release pain, but studies indicate that it increases the risk of suicide for those with a history of deliberate self harm. Employment is a protective factor.
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 87-year-old woman presents with disorientation and restlessness. She has a history of hypertension, atrial fibrillation, polymyalgia rheumatica, osteoarthritis and a hiatus hernia. Her current medications include bisoprolol, digoxin, amlodipine, omeprazole, prednisolone and as required paracetamol. She lives independently and is usually mentally alert. She has been increasingly unwell for the past week, complaining of increased pain in her shoulders, so her GP has increased the dose of prednisolone from 5mg to 30mg daily and added codeine 30mg four times a day. Physical examination and blood tests are unremarkable.
Which of the following is the most likely diagnosis?
Select the SINGLE most likely diagnosis from the list below. Select ONE option only.Your Answer: Chest infection
Correct Answer: Polypharmacy
Explanation:Understanding the Possible Causes of Delirium in the Elderly: A Case Study
This patient is most likely experiencing delirium, which is a common condition among the elderly. One of the leading causes of delirium in this population is polypharmacy, which refers to taking multiple medications. In this case, the patient’s unremarkable physical examination and blood tests suggest that polypharmacy is the most likely explanation for her symptoms. Steroids and opioids, which she recently started taking, are known to cause delirium, especially in older adults. Patients with dementia or mild cognitive impairment are particularly vulnerable to the effects of polypharmacy.
Accidental poisoning is also a possibility, but the patient’s usual independence and mental alertness make this less likely. Additionally, her symptoms have been present for a week, which suggests a longer process than accidental poisoning. A chest infection could also cause delirium, but the patient’s examination and blood tests do not support this diagnosis.
Alcohol withdrawal is another potential cause of disorientation and restlessness, but there is no indication in the patient’s history that she is misusing alcohol. Finally, Alzheimer’s disease is unlikely given the short duration of the patient’s symptoms and her usual mental alertness. Overall, polypharmacy is the most probable cause of this patient’s delirium.

As a side-effect, which antidepressants cause the cheese effect (a hypertensive reaction)?
Your Answer: Monoamine oxidase inhibitors (MAOIs)
Explanation:Differential Diagnosis: Jaundice and Abdominal Symptoms
Gilbert Syndrome:
Gilbert syndrome is an inherited condition that can manifest as jaundice on clinical examination. Patients may also experience non-specific symptoms such as abdominal cramps, fatigue, and malaise. Fasting, febrile illness, alcohol, or exercise can exacerbate jaundice in patients with Gilbert syndrome. Diagnosis is based on a thorough history and physical examination, as well as blood tests that show unconjugated hyperbilirubinaemia.Haemolytic Anaemia:
Haemolysis is the premature destruction of erythrocytes, which can lead to anaemia if bone marrow activity cannot compensate for erythrocyte loss. Mild haemolysis can be asymptomatic, while severe haemolysis can cause life-threatening symptoms such as angina and cardiopulmonary decompensation. Changes in lactate dehydrogenase and serum haptoglobin levels are the most sensitive general tests for haemolytic anaemia.Hepatitis A:
Hepatitis A is a viral infection that results almost exclusively from ingestion, typically through faecal-oral transmission. Symptoms include fatigue, anorexia, nausea, and vomiting. LFT abnormalities are common, and diagnosis is based on serologic testing for immunoglobulin M (IgM) antibody to HAV.Hepatitis B:
Hepatitis B is a viral infection that is transmitted haematogenously and sexually. Symptoms include fatigue, anorexia, nausea, and vomiting. LFT abnormalities are common, and diagnosis is based on serologic testing for hepatitis B surface antigen (HBsAg).Cholecystitis:
Cholecystitis is inflammation of the gall bladder that occurs most commonly because of an obstruction of the cystic duct by gallstones arising from the gall bladder. Symptoms include upper abdominal pain, nausea, vomiting, and fever. Signs of peritoneal irritation may also be present.Conclusion:
In summary, the differential diagnosis of jaundice and abdominal symptoms includes Gilbert syndrome, haemolytic anaemia, hepatitis A, hepatitis B, and cholecystitis. Diagnosis is based on a thorough history and physical examination, as well as blood tests and serologic testing as appropriate. Treatment -

Question 9
Correct

A 70-year-old man visits his doctor for a check-up 3 weeks after commencing mirtazapine (15 mg once daily) for depression. He mentions that his mood, appetite and sleep are starting to improve. Nevertheless, he is struggling with heightened daytime drowsiness since initiating the mirtazapine and finds it challenging. He does not report any other adverse effects.
What alteration to his medication would be the most suitable?Your Answer: Increase the dose of mirtazapine
Explanation:The best course of action to reduce sedation in a patient taking mirtazapine at a low dose (e.g. 15mg) is to increase the dose (e.g. to 45mg). Adding an SSRI or advising the patient to take mirtazapine on alternate days would not be ideal options. Halving the dose of mirtazapine may even worsen daytime somnolence. Stopping mirtazapine and switching to another medication is not recommended if the patient has responded well to mirtazapine.
Mirtazapine: An Effective Antidepressant with Fewer Side Effects
Mirtazapine is an antidepressant medication that functions by blocking alpha2-adrenergic receptors, which leads to an increase in the release of neurotransmitters. Compared to other antidepressants, mirtazapine has fewer side effects and interactions, making it a suitable option for older individuals who may be more susceptible to adverse effects or are taking other medications.
Mirtazapine has two side effects that can be beneficial for older individuals who are experiencing insomnia and poor appetite. These side effects include sedation and an increased appetite. As a result, mirtazapine is typically taken in the evening to help with sleep and to stimulate appetite.
Overall, mirtazapine is an effective antidepressant that is well-tolerated by many individuals. Its unique side effects make it a valuable option for older individuals who may have difficulty sleeping or eating.

A 40-year-old inpatient experienced an episode of acute psychosis. He was given a medication on the ward and later developed severe torticollis.
What is the most probable drug that was administered to the patient?Your Answer: Haloperidol
Explanation:Common Psychiatric Medications and Their Side-Effects
Haloperidol: A typical antipsychotic drug that can cause extrapyramidal side-effects (EPSEs), including acute dystonic reactions. Treatment is with anticholinergic drugs or benzodiazepines.
Clozapine: An atypical antipsychotic mainly used in treatment-resistant schizophrenia. Common side-effects include sedation, constipation, hypersalivation, weight gain, and metabolic syndrome. Rare but important side-effects include agranulocytosis, arrhythmias, and myocarditis. EPSEs are possible but rare.
Diazepam: A benzodiazepine used in anxiety, insomnia, seizures, and muscle spasms. Side-effects include sedation, muscle weakness, drowsiness, and confusion. EPSEs are not a recognised side-effect and may improve with the use of benzodiazepines.
Lithium: A mood stabiliser used in the treatment of mania, depression, and bipolar disorder. Side-effects include gastrointestinal disturbances, tremor, polydipsia, polyuria, and electrolyte disturbances. Lithium-induced hypothyroidism is common. EPSEs are not a side-effect of lithium.
Olanzapine: An atypical antipsychotic used in the treatment of schizophrenia and acute mania. Common side-effects include sedation, weight gain, and metabolic symptoms. EPSEs can occur but are not a typical side-effect of olanzapine.

A 50-year-old man with schizophrenia who is on chlorpromazine experiences an oculogyric crisis. Which side effect of antipsychotic medication does this exemplify?
Your Answer: Acute dystonia
Explanation:Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics.

A 50-year-old woman is prescribed mirtazapine 15mg ON for the treatment of moderate depression, based on her previous positive response to this medication. She has no significant medical history. However, after 4 weeks of taking mirtazapine, she reports experiencing sedation as a side effect and has not achieved the desired therapeutic response. What is the best course of action to manage this situation?
Your Answer: Increase the dose of mirtazapine to 30mg ON
Explanation:Mirtazapine is more likely to cause sedation at lower doses (e.g. 15mg) than at higher doses (e.g. 45mg).
The appropriate course of action is to increase the mirtazapine dose to 30mg at night. If there has been no improvement in symptoms after four weeks, it is reasonable to increase the dose to the usual minimum effective dose. It is important to note that sedation typically decreases with higher doses of mirtazapine due to increased noradrenergic activity.
If the patient does not respond to or cannot tolerate an increase in mirtazapine, switching to an alternative medication such as fluoxetine or venlafaxine may be considered. However, it is advisable to try the usual minimum effective dose of mirtazapine before deciding to switch medications.
Amitriptyline and other TCAs are no longer commonly used in the treatment of depression due to the risk of overdose.
In cases of severe depression, depression that does not respond to primary care management, or suspected bipolar disorder, it is recommended to seek a secondary care opinion.

For what has the National Institute for Health and Care Excellence (NICE) recommended the use of varenicline?
Your Answer: Smoking cessation (cigarettes)
Explanation:The Use of Varenicline in Smoking Cessation and Other Substance Withdrawals
Varenicline, marketed as Champix®, is a medication used in combination with motivational support to aid smoking cessation. The National Institute for Health and Care Excellence (NICE) recommends offering varenicline or nicotine replacement therapy (NRT) to all smokers, along with advice and encouragement to quit. The choice of therapy depends on factors such as the smoker’s compliance, availability of counseling and support, previous experience with cessation aids, contraindications, and personal preference. However, varenicline use has been associated with changes in behavior and thinking, anxiety, psychosis, mood swings, depression, and suicidal ideation, so monitoring is advised.
While varenicline is not currently indicated for cannabis cessation, some studies suggest that it may reduce the enjoyment reported from using cannabis, which could lead to further investigation in this area. However, varenicline has no role in the treatment of alcohol withdrawal, and the FDA has warned that people taking varenicline should reduce their alcohol intake due to the potential for unusual behavior, including aggression. The use of varenicline for opioid withdrawal in patients with chronic pain is also under investigation but is not currently recommended. Finally, varenicline is not indicated for cocaine cessation.

A 50-year-old man who is on antipsychotic medication for schizophrenia complains of extreme restlessness. Which side-effect of the medication could be causing this?
Your Answer: Akathisia
Explanation:Severe restlessness may be caused by antipsychotics, known as akathisia.
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.

A 42-year-old man presents for follow-up. He was prescribed paroxetine for depression six months ago, but stopped taking it five days ago due to perceived lack of efficacy. He has a history of asthma but no other significant medical history. Over the past two days, he has been experiencing heightened anxiety, sweating, headaches, and a sensation of needles in his head. During the appointment, he is restless and pacing. What is the most likely cause of his symptoms?
Your Answer: Selective serotonin reuptake inhibitor`discontinuation syndrome
Explanation:Compared to other selective serotonin reuptake inhibitors, paroxetine has a greater likelihood of causing discontinuation symptoms.
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 25-year-old male presents to the Emergency Department with severe abdominal pain. He appears to be in distress, shivering and writhing on the trolley. Despite previous investigations for abdominal pain, no cause has been found. The patient insists that he will harm himself unless he is given morphine for the pain. Which of the following best describes this behavior?
Your Answer: Malingering
Explanation:Fabricating or inflating symptoms for financial benefit is known as malingering, such as an individual who feigns whiplash following a car accident in order to receive an insurance payout.
This can be challenging as the individual may be experiencing withdrawal symptoms from opioid abuse. Nevertheless, among the given choices, the most suitable term to describe the situation is malingering since the individual is intentionally reporting symptoms to obtain morphine.
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 man of 45 years presents following the death of his wife.
Which one of the following is going to heighten your suspicion of an abnormal grief reaction?
Your Answer: Delayed or absent grief
Explanation:Understanding Abnormal and Normal Grief Reactions
Grief is a highly individualized experience that can be influenced by personal, social, and cultural factors. There are three recognized types of abnormal grief reactions: delayed, inhibited, and prolonged. Delayed grief is characterized by a delay of more than two weeks before grieving begins, or sometimes not occurring at all until triggered by another subsequent bereavement. Inhibited grief occurs when the bereaved person appears minimally affected by the death, and prolonged grief lasts significantly longer than average.
On the other hand, normal grief reactions are characterized by features such as sadness, weeping, poor sleep, reduced appetite, motor restlessness, searching for the deceased, poor concentration and memory, low mood (but not frank depression), and the impression of seeing or hearing the deceased. Poor memory, brief episodes of seeing the dead person, poor concentration, and searching for the deceased are all common manifestations of a normal grief reaction.
It is important to note that there is a great degree of flexibility when assessing whether a grief reaction is normal or abnormal, as it is a highly personal experience. Understanding the different types of grief reactions can help individuals and their loved ones navigate the grieving process and seek appropriate support.

A 57-year-old woman and her husband arrive at the hospital with concerns about her increasing forgetfulness. The husband reports that she has lost her keys multiple times and struggles to remember her daily activities. The patient herself is worried about developing dementia, especially since her grandmother had it. She has diabetes, hypertension, and agitated depression, and has been taking medication for a recent urinary tract infection. Which of the listed medications is the most likely cause of her memory problems?
Medication list:
- Metformin/Glicizide for diabetes
- Lorazepam for sleep and anxiety
- Citalopram for depression
- Nitrofurantoin for urinary tract infectionYour Answer: Lorazepam
Explanation:Lorazepam is a benzodiazepine drug that can cause anterograde amnesia as a side effect, resulting in significant impairment of memory recall and the formation of new memories. Additionally, it is utilized in anesthesia.
Benzodiazepines are drugs that enhance the effect of the neurotransmitter GABA, which inhibits brain activity. They are used for various purposes, including sedation, anxiety relief, muscle relaxation, and seizure prevention. However, patients can develop a tolerance and dependence on these drugs, so they should only be prescribed for a short period of time. When withdrawing from benzodiazepines, it is important to do so gradually to avoid withdrawal symptoms, which can include insomnia, anxiety, and seizures. Barbiturates are another type of drug that affect GABA, but they work differently than benzodiazepines by increasing the duration of chloride channel opening.

Despite intensive investigations, no cause for his symptoms has been identified.
Which of the following is the most likely diagnosis?
Your Answer: Somatisation disorder
Explanation:Understanding Somatoform Disorders: Exploring Possible Diagnoses for a Patient with Medically Unexplained Symptoms
This patient presents with medically unexplained symptoms (MUS), which are collectively known as somatoform disorders. The chronicity and large number of diverse symptoms in this case suggest somatisation disorder, a condition that affects 5-10% of repeat attenders in specialist clinics. Somatisation disorder is more common in women than in men and tends to start in early adulthood. Treatment involves psychological interventions (e.g. CBT) and/or antidepressant medication, but patients are frequently reluctant to engage in these.
Other possible diagnoses for MUS include conversion disorder, hypochondriasis, and undifferentiated somatoform disorder. Conversion disorder presents with neurological symptoms, usually some type of loss of function, while hypochondriasis is associated with a persistent preoccupation to have one or more serious and progressive physical illnesses. In hypochondriasis, the patient puts emphasis on the presence of one (or more) determinate illness and on having it diagnosed. In somatisation disorder, such as in this vignette, the emphasis is on the symptoms (for which the patients seeks a medical explanation), rather than on a specific diagnosis. Undifferentiated somatoform disorder is used when the MUS are multiple and persistent, but the diagnostic criteria for somatisation disorder cannot be fulfilled.
Depression is an important co-morbidity in patients with somatoform disorders, but in this vignette, the combination of physical symptoms and the extensive and complex history of contact with primary and secondary services makes somatisation disorder the most likely diagnosis. It is particularly important to use a patient-centred, empathic interview style with patients with somatoform disorders to ensure they receive the appropriate care and support.

Question 20
Incorrect

Sarah is a 25-year-old woman with schizophrenia who has had multiple admissions under the Mental Health Act (1983).
Her consultant has utilized a Section of the Mental Health Act that permits Sarah to be brought back to the hospital for treatment if certain conditions are not met, such as if she declines to take her depot antipsychotic.
What is the name of this Section?Your Answer:
Correct Answer: Section 17a (Community Treatment Order)
Explanation:Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.
Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.
Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.
Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.
Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.
Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.
Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

Question 21
Incorrect

A 67-year-old male with a history of ischaemic heart disease is experiencing depression after a recent heart attack. Which antidepressant would be the most suitable to initiate?
Your Answer:
Correct Answer: Sertraline
Explanation: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 22
Incorrect
-
A 30-year-old man visits his doctor for a follow-up on his depression. He was given fluoxetine 4 months ago for a case of moderate depression. He reports that his mood has been great lately, that he no longer feels despair about the future, and that he has resumed his hobbies of playing basketball and writing.
The patient indicates that he would like to discontinue taking fluoxetine since he believes his depression has been resolved.
What advice should be given?Your Answer:
Correct Answer: Continue fluoxetine for at least 6 months
Explanation:To decrease the risk of relapse, it is recommended to continue antidepressant treatment for at least 6 months after remission of symptoms. Therefore, the correct response is to continue fluoxetine for at least 6 months at the same dose. It should be noted that in elderly patients, treatment should be continued for 12 months, and in those with a history of recurrent depression, treatment should be continued for 2 years. Stopping fluoxetine or tapering the dose over 2 weeks is not appropriate, as treatment should be continued for at least 6 months before considering stopping or tapering. When fluoxetine is stopped, it is recommended to taper the dose over 6-12 weeks to minimize the risk of withdrawal symptoms.
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.

A 17-year-old girl is brought to your clinic by her parents due to concerns about her weight loss (her BMI is now 18.5 kg/m2, down from 21 kg/m2 one year ago). You are familiar with the patient and have ruled out any physical causes for her weight loss. When you inquire about purging behaviors, such as self-induced vomiting, she appears hesitant to answer, but you notice that her tooth enamel is eroded. She expresses feeling extremely overweight and has been experiencing low mood for several months, finding little pleasure in anything except for when she indulges in too much chocolate and bread. However, afterwards, she feels even more disgusted with herself.
What is the most appropriate diagnosis for her condition?Your Answer:
Correct Answer: Bulimia nervosa
Explanation:Understanding Eating Disorders: Bulimia Nervosa
Bulimia nervosa is an eating disorder that is characterized by binge eating followed by purging behaviors such as vomiting, laxative abuse, excessive exercise, and drug use. Individuals with bulimia often experience feelings of loss of control and intense guilt during binge episodes. Pitting of tooth enamel caused by stomach acid is a common sign of regular vomiting. Unlike anorexia nervosa, bulimia is not usually associated with severe weight loss. The condition is ten times more common in women. It is important to recognize the symptoms of bulimia and seek professional help for proper diagnosis and treatment.

Question 24

A 24-year-old female presents to the emergency department with a complaint of left leg weakness that started 2 hours ago. She reports no weakness in her face or upper limbs, and her speech is normal. She has no medical history and takes no regular medications.
Upon examination, the emergency physician suspects a non-organic cause. The patient is placed in a supine position and asked to raise her right leg against resistance while keeping it straight. The physician places his hand under the left heel and feels pressure under his hand.
What is the name of this clinical sign or test?Your Answer:
Correct Answer: Hoover's sign
Explanation:Hoover’s sign is a useful clinical tool that can quickly differentiate between organic and non-organic leg paresis. In cases of non-organic paresis, pressure is felt under the affected leg when the unaffected leg is lifted against pressure. This is due to involuntary contralateral hip extension.
Based on this scenario, the likely diagnosis is a conversion disorder, which is characterized by the loss of motor function in the leg without any organic cause. The positive result of Hoover’s sign supports this diagnosis.
Babinski’s sign is a reflex that involves dorsiflexion of the big toe upon plantar stimulation. It is indicative of an upper motor neuron lesion of the corticospinal tract.
BrudziĹ„ski’s sign is a reflex that involves the flexion of the hips with forced flexion of the neck. It is typically associated with meningitis but can also be present in patients with subarachnoid hemorrhage and encephalitis.
The glabellar tap sign, also known as Myerson’s sign, involves tapping the area above the nose and between the eyebrows (glabella) repeatedly. Healthy patients usually blink in response to the first 2-3 taps, but if a patient is unable to resist blinking beyond this, it can be indicative of early Parkinson’s disease.
The straight leg raise test, also known as Lasègue’s sign, involves raising the straight leg to reproduce radiating leg pain. A positive result indicates a likely lumbar disc herniation.
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 has had > 15 very short relationships in the past year, all of which he thought were the love of his life. He is prone to impulsive behaviour such as excessive spending and binge drinking, and he has experimented with drugs. He also engages in self-harm.
Which of the following personality disorders most accurately describes him?Your Answer:
Correct Answer: Borderline personality disorder
Explanation:Understanding Personality Disorders: Clusters and Traits
Personality disorders can be categorized into three main clusters based on their characteristics. Cluster A includes odd or eccentric personalities such as schizoid and paranoid personality disorder. Schizoid individuals tend to be emotionally detached and struggle with forming close relationships, while paranoid individuals are suspicious and distrustful of others.
Cluster B includes dramatic, erratic, or emotional personalities such as borderline and histrionic personality disorder. Borderline individuals often have intense and unstable relationships, exhibit impulsive behavior, and may have a history of self-harm or suicide attempts. Histrionic individuals are attention-seeking, manipulative, and tend to be overly dramatic.
Cluster C includes anxious personalities such as obsessive-compulsive personality disorder. These individuals tend to be perfectionists, controlling, and overly cautious.
Understanding the different clusters and traits associated with personality disorders can help individuals recognize and seek appropriate treatment for themselves or loved ones.

As a junior doctor in psychiatry, you are evaluating a young man in the Emergency Department who was brought in by the police for carrying a knife. Your conversation with him goes as follows:
Doctor: I see that the police have brought you in from the town centre today. Can you tell me why, as a young man, you felt the need to carry a knife?Your Answer:
Correct Answer: Tangentiality
Explanation:Tangentiality is when someone goes off on a tangent and does not return to the original topic. It is a type of formal thought disorder that is often seen in people with schizophrenia. The person may provide excessive and unnecessary details that are somewhat relevant to the question but never answer the central point. Circumstantiality is similar, but the person ultimately provides an answer. Clang associations involve using words that sound similar but have no logical connection, while perseveration is when someone continues to respond to a previous question even after a new one has been asked.
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 50-year-old man who is being treated for schizophrenia with chlorpromazine experiences involuntary puckering of the lips. Which side effect of antipsychotic medication does this exemplify?
Your Answer:
Correct Answer: Tardive dyskinesia
Explanation:Tardive dyskinesia can be caused by antipsychotics.
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.

In an elderly patient, which of the following is the single most likely statement indicating an increased risk of suicide?
Your Answer:
Correct Answer: A direct statement of intent to attempt suicide
Explanation:Understanding Suicide Risk Factors
Suicide is a complex issue with various risk factors that can contribute to its occurrence. One of the most obvious warning signs is a direct statement of intent to attempt suicide. It is important to take these statements seriously and seek help immediately.
Physical illness, especially if it is prolonged and associated with pain and/or a poor prognosis, is also a well-recognized risk factor for suicide. Additionally, caring for a dying friend or relative can increase the risk, albeit to a lesser extent.
Unemployment is another risk factor, as it can lead to feelings of hopelessness and financial strain. Living alone, particularly after a bereavement, can also indicate a higher risk, especially if the person was dependent on the deceased.
While paranoid delusions can occur in depressive illness, they do not have any special significance in assessing suicide risk. However, approximately one in twenty people with schizophrenia attempt suicide, with a higher risk at the onset of the illness and if there is associated depressive illness.
It is important to understand these risk factors and seek help if you or someone you know is struggling with suicidal thoughts. Remember, there is always hope and help available.

A 35-year-old man presents with symptoms of depression, difficulty sleeping, and a strong desire for sugary foods during the winter months. He reports that his symptoms are more severe in the winter than in the summer. He has no history of other mental health issues or physical problems. What is the most probable diagnosis?
Your Answer:
Correct Answer: Seasonal affective disorder (SAD)
Explanation:Differentiating Seasonal Affective Disorder from Other Depressive Disorders
Seasonal affective disorder (SAD) is a type of depression that occurs in a regular temporal pattern, typically beginning in autumn or winter and ending in spring or summer. Unlike classic major depression, SAD is characterized by symptoms of hyperphagia, hypersomnia, and weight gain. The cause of SAD is believed to be a malfunction of the light-sensitive hormone melatonin during winter. Treatment involves phototherapy, which exposes individuals to bright light for several hours a day.
Reactive depression, on the other hand, is a subtype of major depression that occurs as a result of an external event, such as a relationship breakdown or bereavement. There is no indication of a stressful life event in the presented vignette.
Bipolar affective disorder is characterized by distinct episodes of depression and mania, which is not evident in the vignette. Dysthymia is a persistent depression of mood that does not fully meet the criteria for a diagnosis of major depression and does not have a definite seasonal variation like SAD.
Finally, double depression occurs when one or more episodes of major depression occur on a background of dysthymia. It is important to differentiate SAD from other depressive disorders to provide appropriate treatment and management.

At school, she has frequently been involved in physical altercations with her peers and was recently reprimanded for damaging school property.
What is the most probable diagnosis?Your Answer:
Correct Answer: Conduct disorder
Explanation:Understanding Conduct Disorder and Differential Diagnoses
Conduct disorder is a psychiatric condition characterized by persistent and severe antisocial behaviors that violate social norms and the rights of others. These behaviors may include excessive fighting, cruelty to people or animals, destruction of property, persistent disobedience, and repeated lying. However, conduct disorder can be easily confused with other psychiatric conditions that present with similar symptoms. Here are some differential diagnoses to consider:
Depression: While depressive disorders can present with oppositional symptoms, they are usually accompanied by disturbances to appetite, sleep, and anhedonia, which are not seen in conduct disorder. However, depression can coexist with conduct disorder.
Adjustment reaction: Conduct disturbance can also be a reaction to an external stressor, such as divorce, bereavement, abuse, or trauma. However, these symptoms usually occur within three months of the stressor and can last up to six months. If there is no mention of an external stressor, conduct disorder is more likely.
Attention-deficit hyperactivity disorder (ADHD): Children with ADHD exhibit symptoms of inattention associated with hyperactivity and impulsiveness, which can affect social and academic functioning. However, unlike conduct disorder, these behaviors do not usually violate societal norms or the rights of others. ADHD can also coexist with conduct disorder.
Autism spectrum disorder: Children with autism spectrum disorder may present with emotional lability, aggressive outbursts, and destructive behavior, usually in response to an unexpected change in routine or sensory overload. However, there are typical features of autism, such as sensory hypersensitivity, that are not mentioned in conduct disorder. Autism can also coexist with conduct disorder.
In conclusion, conduct disorder is a serious psychiatric condition that requires early identification and intervention. However, it is important to consider other differential diagnoses to ensure accurate diagnosis and appropriate treatment.

Sarah is a 44-year-old who undergoes regular blood tests as part of her health check-up. Her blood test results are as follows:
Na+ 125 mmol/l
K+ 4.3 mmol/l
Urea 5.3 mmol/l
Creatinine 60 µmol/l
She is currently taking sertraline, carbimazole, amlodipine, metformin, and aspirin. Which medication is most likely responsible for her hyponatremia?Your Answer:
Correct Answer: Sertraline
Explanation:Hyponatraemia is a known side effect of SSRIs, with sertraline being the specific medication associated with this condition. Other drugs that can cause low sodium levels include chlorpropramide, carbamazepine, tricyclic antidepressants, lithium, MDMA/ecstasy, tramadol, haloperidol, vincristine, desmopressin, and fluphenazine.
Understanding the Side-Effects and Interactions of SSRIs
SSRIs, or selective serotonin reuptake inhibitors, are commonly prescribed antidepressants that can have various side-effects and interactions with other medications. The most common side-effect of SSRIs is gastrointestinal symptoms, and patients taking these medications are at an increased risk of gastrointestinal bleeding. To mitigate this risk, a proton pump inhibitor should be prescribed if the patient is also taking a NSAID. Hyponatraemia, or low sodium levels, can also occur with SSRIs, and patients should be vigilant for increased anxiety and agitation after starting treatment.
Fluoxetine and paroxetine have a higher propensity for drug interactions, and citalopram has been associated with dose-dependent QT interval prolongation. The Medicines and Healthcare products Regulatory Agency (MHRA) has advised that 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 has been reduced for certain patient populations.
SSRIs can also interact with other medications, such as NSAIDs, warfarin/heparin, aspirin, and triptans. It is important to review patients after starting antidepressant therapy and to gradually reduce the dose when stopping treatment to avoid discontinuation symptoms. These symptoms can include mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.
In summary, understanding the potential side-effects and interactions of SSRIs is crucial for safe and effective treatment of depression and other mental health conditions. Patients should be closely monitored and counseled on the risks and benefits of these medications.

A 65-year-old woman comes to you with complaints of feeling low and having trouble sleeping. Upon further discussion and administering a validated symptom measure, you diagnose her with moderate depression. She has a medical history of ischemic heart disease and is currently on aspirin, ramipril, and simvastatin. What would be the best course of action in this situation?
Your Answer:
Correct Answer: Start sertraline + lansoprazole
Explanation: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.

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.

A 25-year-old man visits his general practice surgery, explaining that his depression has been cured after four months taking sertraline. He says he is ready to stop taking the medication immediately and is looking forward to being 'normal again'.
What is the most appropriate management advice you can give this patient?Your Answer:
Correct Answer: He should be treated for at least six months
Explanation:Duration of Antidepressant Treatment for Depression
It is recommended that a single episode of depression should be treated for at least six months after recovery to prevent relapse. Recurrent episodes warrant at least 12 months of treatment after recovery. Stopping antidepressant treatment immediately on recovery puts patients at a high risk of relapse, with 50% of patients experiencing a relapse of their depressive symptoms. During the recovery phase, adults should receive the same dose used for the treatment of the acute phase. The medication should then be tapered off over a few weeks, according to the type of antidepressant used.
Stopping medication prematurely, such as after one month or six weeks, would put the patient at a high risk of relapse. If the patient has been using antidepressants over a very short term and has found it maximally effective, they may be able to come off medication sooner than six months. However, this should be managed with caution and only recommended if there are other extenuating factors which would cause them to want to stop, such as side-effects or poor compliance. In this case, the patient has been using sertraline for four months already, has not indicated poor compliance, and there is no indication of issues with side-effects.

A teenage boy presents with bizarre delusions, a blunted affect and tangential thought processes.
Which one of the following characteristics would indicate an unfavourable prognosis?
Your Answer:
Correct Answer: A prolonged premorbid history of social withdrawal
Explanation:Understanding Prognostic Factors in Schizophrenia
Schizophrenia is a complex mental illness that can have a significant impact on a person’s life. While there is no cure for schizophrenia, early diagnosis and treatment can help manage symptoms and improve outcomes. Understanding prognostic factors can also be helpful in predicting the course of the illness and developing appropriate treatment plans.
One important factor to consider is the premorbid history of the patient. A prolonged history of social withdrawal is predictive of more severe and long-lasting psychopathology. Additionally, a family history of schizophrenia in first-degree relatives can have a negative impact on prognosis, while a history in second-degree relatives has little significance.
The onset of illness is also an important factor to consider. In schizophrenia, a sudden onset of illness has a more favourable prognosis than an insidious one. However, if the patient presents with catatonic symptoms, this is actually an indicator of a relatively good prognosis.
Finally, MRI changes are associated with more severe symptoms and clinical course in people with schizophrenia. While it is not fully clear whether these changes are fixed or progress over time, they can be an important factor to consider in developing a treatment plan.
Overall, understanding these prognostic factors can help clinicians develop appropriate treatment plans and provide better support for patients with schizophrenia.

A 25-year-old man presents to the clinic with persistent beliefs that his coworkers are plotting against him and trying to sabotage his work, despite reassurance and evidence to the contrary. He has had multiple heated arguments with his colleagues and after each one, he becomes aggressive and blames them for his outbursts. He sometimes feels like he cannot function without them, but also sometimes feels that they are out to get him. He has a history of a recent suicide attempt and has difficulties trusting his family as he feels they are part of the conspiracy. What is the most likely diagnosis?
Your Answer:
Correct Answer: Borderline personality disorder
Explanation:The young man in question is likely suffering from borderline personality disorder (BPD), also known as emotionally unstable personality disorder (EUPD). This condition is characterized by unstable relationships, alternating between idealization and devaluation of others, recurrent self-harm, unstable self-image and self-esteem, suicidal behavior, difficulty controlling anger, and efforts to avoid abandonment. All of these traits are present in this patient, making BPD the most likely diagnosis.
Narcissistic personality disorder is not a likely diagnosis for this patient, as it is characterized by a grandiose sense of self-importance, lack of empathy, and a sense of entitlement. These traits are not present in this patient, and his periods of devaluing her partner are temporary and not pervasive.
Dependent personality disorder is also an unlikely diagnosis, as this condition is characterized by a pervasive need for others to make decisions for the patient and constant reassurance. While the patient has felt that he cannot live without his partner in the past, his labile mood and alternating view of his partner make this diagnosis less likely.
Paranoid personality disorder is also an unlikely diagnosis, as patients with this condition tend to be reluctant to confide in others and have an unforgiving attitude when insulted or questioned. The patient in question does not exhibit these traits, and his difficulty with trusting friends is likely due to his belief that he is undeserving of them.
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 conspirational 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 19-year-old long-distance runner who is currently preparing for a regional marathon seeks an appointment with the team doctor due to an unusual sensation in her legs. She reports feeling numbness below her knee. During the examination, the doctor observes sensory loss below the left knee in a non-dermatomal distribution. The team doctor suspects a non-organic cause of her symptoms. What type of disorder is this an example of?
Your Answer:
Correct Answer: Conversion disorder
Explanation:Conversion disorder is a condition that often results in the loss of motor or sensory function and is believed to be triggered by stress.
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 25-year-old man has a known psychiatric disorder. His condition causes him to have persecutory delusions and poor organisation of thoughts. He is easily distracted and struggles to maintain good eye contact during conversations. What is a factor that is linked to a negative prognosis in this disorder?
Your Answer:
Correct Answer: Low IQ
Explanation:Schizophrenia is a mental disorder that can have varying prognoses depending on certain factors. Some indicators associated with a poor prognosis include a strong family history of the disorder, a gradual onset of symptoms, a low IQ, a prodromal phase of social withdrawal, and a lack of an obvious precipitant. These factors can contribute to a more severe and chronic course of the illness, making it more difficult to manage and treat. It is important for individuals with schizophrenia and their loved ones to be aware of these indicators and seek appropriate treatment and support.

Liam is a 30-year-old software engineer who has been admitted to the hospital due to a relapse of his schizophrenia. He has been detained under section 3 of the Mental Health Act for 2 weeks after refusing to take his medication.
The consultant psychiatrist suggests starting Liam on risperidone, but during the team meeting, Liam was informed of the potential risks and benefits of the medication and decided he does not want to take it. The team believes that Liam has the capacity to make this decision, but they also feel that he needs treatment with an antipsychotic to reduce the risk to himself and others.
What is the most appropriate course of action in this situation?Your Answer:
Correct Answer: Rosie can be treated against her will under section 3, even if she has capacity
Explanation:If a patient is under section 2 or 3, treatment can be administered even if they refuse it. Patients who are detained under section 3 can be treated against their will, regardless of their capacity. However, after three months, if the patient still refuses treatment, an impartial psychiatrist must review the proposed medication and agree with the treating team’s plan. The Mental Health Act takes precedence over the Mental Capacity Act, so a best interests meeting is not necessary. The treating team must consider the patient’s best interests, and in this case, they believe that medication is necessary for Rosie’s mental health. While benzodiazepines can alleviate agitation and distress, they are unlikely to improve her psychotic symptoms, so they are not a suitable option. If Rosie continues to refuse treatment after three months under section 3, a second opinion will be required.
Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.
Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.
Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.
Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.
Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.
Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.
Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

As a junior doctor in the Emergency Department, you encounter a 40-year-old woman who has been brought in by the police under a section 135. The police had to obtain a warrant as part of the process. The patient is currently agitated and speaking incoherently about religious phrases. She has a documented history of severe depression.
What powers does section 135 grant to the police in this situation?Your Answer:
Correct Answer: To bring a person with suspected mental health issues in from their property
Explanation:If the police believe that someone requires a mental health assessment or treatment, they can request a section 135 to remove the individual from their property. The procedure involves an Approved Mental Health Practitioner (AMHP) presenting evidence at a Magistrate’s Court to obtain a warrant. This warrant permits the Police, an AMHP, and a registered medical practitioner to enter the premises and conduct an assessment or take the person to a safe location for evaluation.

You are assessing a 55-year-old man who has been admitted with pneumonia. His medical history indicates that he consumes approximately 70-80 units of alcohol per week. Which medication would be the most suitable to administer to prevent the onset of alcohol withdrawal symptoms?
Your Answer:
Correct Answer: Chlordiazepoxide
Explanation: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.

A 30-year-old woman who delivered a baby 3 days ago comes for evaluation due to her mood concerns. She is experiencing trouble sleeping and feels generally anxious and weepy. Additionally, she has noticed that she is becoming irritable with her spouse. This is her initial pregnancy, she is not nursing, and there is no previous history of mental health disorders. What is the best course of action for her management?
Your Answer:
Correct Answer: Explanation and reassurance
Explanation:This woman is experiencing the common postpartum mood disorder known as baby-blues, which affects approximately two-thirds of women. Although lack of sleep can be a symptom of depression, it is a normal occurrence for new mothers.
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.

A young librarian seeks therapy as he is lonely and unhappy. He describes a solitary life cataloguing books all day and then remaining alone all night and on weekends. He declines invitations for dinners, as he feels anxious when other people are around.
Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Social phobia
Explanation:Differentiating Anxiety Disorders: A Vignette Analysis
The following vignette describes a patient with symptoms of anxiety in a social situation. To properly diagnose the patient, it is important to differentiate between various anxiety disorders.
Social Phobia: This disorder is characterized by anxiety in public, particularly when feeling scrutinized. It typically starts in adolescence and is equally prevalent in men and women. Some patients have a specific social phobia, while others have a more diffuse type. Treatment is mainly with psychological interventions.
Generalized Anxiety Disorder (GAD): GAD is characterized by non-specific and persistent anxiety. Patients feel anxious most days for periods of at least several weeks, and may experience a variety of worries that are not objectively warranted by their circumstances. Autonomic and motor overactivity are also common.
Panic Disorder: Panic attacks are recurrent episodes of severe anxiety that occur unpredictably and under unrestricted circumstances. A diagnosis of panic disorder can be given only if several panic attacks have occurred in about 1 month in situations that do not pose an objective danger, in unrestricted circumstances and with relative freedom from symptoms of anxiety between attacks.
Separation Anxiety Disorder: This disorder is mainly diagnosed in children, although an adult form has been increasingly recognized. Symptoms include anxiety and fear when separated from emotionally attached individuals, and avoidance of being alone.
Conduct Disorder: This disorder is a precursor to dissocial personality disorder and presents as a persistent and repetitive pattern of dissocial behavior beyond the expected mischief and rebelliousness of childhood and adolescence.
In the vignette, the patient’s anxiety is specific to certain situations and therefore predictable, which excludes the diagnosis of panic disorder. The patient’s symptoms do not fit the criteria for GAD or separation anxiety disorder. The most likely diagnosis is social phobia, which is characterized by anxiety in public situations.

A 70-year-old retired teacher comes to the clinic with a persistent conviction that his daughter has been replaced by a stranger for the past 8 months. The patient has a history of dementia due to Alzheimer's disease.
What is the probable diagnosis?Your Answer:
Correct Answer: Capgras syndrome
Explanation:Capgras syndrome is a condition where an individual has a false belief that their friend or partner has been replaced by an imposter who looks identical to them. Othello syndrome is characterized by an unfounded suspicion that one’s partner is cheating on them. De Clerambault syndrome is a delusional belief that someone of higher social or professional status is in love with the individual. Cotard syndrome is a condition where an individual has a delusional belief that they are dead.
Understanding Capgras Syndrome
Capgras syndrome is a condition characterized by a false belief that a loved one has been replaced by an imposter who looks identical to them. This delusion can be distressing for both the person experiencing it and their loved ones. The syndrome is often associated with neurological or psychiatric disorders, such as schizophrenia, dementia, or traumatic brain injury.
Individuals with Capgras syndrome may recognize the physical features of their loved ones but believe that they are not the same person they once knew. They may also feel that the imposter is trying to harm them or their loved one. This can lead to feelings of paranoia and fear.
Treatment for Capgras syndrome typically involves a combination of medication and therapy. Antipsychotic medication may be prescribed to alleviate symptoms of psychosis, while cognitive-behavioral therapy can help individuals challenge their delusions and develop coping strategies.

A 75-year-old man with a long-standing history of schizophrenia is being seen by his psychiatrist. He was admitted to the psychiatry unit six months ago due to delusions that he was being tracked by spies. At the time of admission, he was taking quetiapine, but it was changed to aripiprazole 400 mg monthly depot. Recently, he has been expressing to his wife that he believes his food is poisoned. His wife thinks that his new medication is not effective. What is the most suitable course of action for managing this patient?
Your Answer:
Correct Answer: Clozapine
Explanation:Clozapine is the appropriate choice for patients with schizophrenia who have not responded adequately to at least two antipsychotics. In this case, the patient has already tried quetiapine and aripiprazole without success, making clozapine a suitable option. However, it requires careful monitoring and titration. Continuing aripiprazole is not recommended as the patient has been on the highest dose for six months and is still experiencing delusional ideas. Haloperidol is a typical antipsychotic that can be used for schizophrenia, but atypical antipsychotics are preferred due to fewer side effects. Lorazepam is not a long-term antipsychotic and is only useful for managing severe agitation in patients with 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.

You are on GP rotation and you assess a 22-year-old student who reports feeling consistently low for the past 6 months. You administer a PHQ-9 questionnaire which indicates persistent mild depression. What is the first line treatment for this patient?
Your Answer:
Correct Answer: Psychological intervention
Explanation:The primary treatment for mild depression is psychological intervention, typically obtained through an IAPT referral. Although a patient may also be prescribed a Serotonin Specific Reuptake Inhibitor (SSRI) while waiting for their referral, it is important to note that the NICE guidelines prioritize the consideration of an IAPT referral as the first line of treatment. Therefore, an IAPT referral is the most appropriate answer in this scenario.
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.

A 19-year-old man with a history of anxiety and depression is being managed by the Child and Adolescent Mental Health Service. They have suggested prescribing an SSRI. What is the most suitable medication to prescribe?
Your Answer:
Correct Answer: Fluoxetine
Explanation:Fluoxetine is the preferred SSRI for children and adolescents.
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.

As a junior doctor in a community mental health team, you are attending to a 35-year-old woman who is suffering from moderate-severe depression. She often voices out intense suicidal ideations and has a history of intentional overdose. Which category of antidepressants is currently less utilized due to their high toxicity in overdose?
Your Answer:
Correct Answer: Tricyclic antidepressants
Explanation:Tricyclic antidepressants are not commonly used for depression anymore due to their high risk of causing dangerous overdose. Therefore, when selecting an antidepressant for a patient who is at high risk of overdose, it is important to choose a class of antidepressants that are less toxic if taken in excess. TCAs have a narrow therapeutic index, which means that even moderate doses can lead to severe cardiovascular and CNS toxicity. Complications of TCA overdose include prolonged hypotension, cardiac arrhythmias, and seizures, which can ultimately result in death due to cardiovascular collapse.
Diagnosis of TCA overdose is typically made based on clinical presentation, and classic ECG changes may be observed, such as sinus tachycardia progressing to wide complex tachycardia and ventricular arrhythmias as the severity of intoxication increases. Treatment involves correcting acidosis, hypoxia, and electrolyte imbalances, as well as administering hypertonic sodium bicarbonate to improve conduction abnormalities and hypotension. Anti-arrhythmic drugs should generally be avoided, and benzodiazepines are the preferred treatment for seizures.
Tricyclic Antidepressants for Neuropathic Pain
Tricyclic antidepressants (TCAs) were once commonly used for depression, but their side-effects and toxicity in overdose have led to a decrease in their use. However, they are still widely used in the treatment of neuropathic pain, where smaller doses are typically required. TCAs such as low-dose amitriptyline are commonly used for the management of neuropathic pain and the prophylaxis of headache, while lofepramine has a lower incidence of toxicity in overdose. It is important to note that some TCAs, such as amitriptyline and dosulepin, are considered more dangerous in overdose than others.
Common side-effects of TCAs include drowsiness, dry mouth, blurred vision, constipation, urinary retention, and lengthening of the QT interval. When choosing a TCA for neuropathic pain, the level of sedation may also be a consideration. Amitriptyline, clomipramine, dosulepin, and trazodone are more sedative, while imipramine, lofepramine, and nortriptyline are less sedative. It is important to work with a healthcare provider to determine the appropriate TCA and dosage for the individual’s specific needs.

A 14-year-old boy comes to the clinic with complaints of sudden jerking movements of his neck, causing his head to move involuntarily from left to right. He has been experiencing these symptoms for a few years, but lately, he has been feeling embarrassed as he involuntarily utters swear words in social situations. These symptoms worsen when he is under stress. What is the most probable diagnosis for this patient?
Your Answer:
Correct Answer: Tourette’s syndrome
Explanation:Differentiating between Mental Disorders: Tourette’s Syndrome, Malingering, Conduct Disorder, Dissocial Personality Disorder, and Schizophrenia
Tourette’s Syndrome is a tic disorder that usually develops in childhood or adolescence, characterized by multiple motor tics and one or more vocal tics. The vocal tics need not be complete words or phrases and are often throat-clearing and grunting. Anti-psychotics such as pimozide, risperidone, and sulpiride have been shown to be of benefit.
Malingering is the act of fabricating symptoms for some sort of secondary gain, such as financial, manipulative, avoidance of school, obtaining drugs, or gaining sympathy or attention.
Conduct Disorder is a mental disorder diagnosed before or after the age of 10, characterized by a persistent and repetitive pattern of behavior that violates either the basic rights of others or goes against age-developmental norms. Childhood onset disorder can be linked to attention deficit/hyperactivity disorder (ADHD) type symptoms.
Dissocial Personality Disorder is characterized by a long-term disregard for others or the violation of others. Its precursor is conduct disorder. Antisocial personality disorder can be diagnosed when the patient reaches the age of 18 and has a history of conduct disorder in childhood or adolescence.
Schizophrenia does not typically present with involuntary movements. There is also no history of hallucinations, auditory or visual, or confused thinking.

A 25-year-old man has recurrent, persistent, intrusive, distressing thoughts and images of his friends getting hurt. He reports that these thoughts seem to originate from his own mind, but he considers them to be irrational.
Which symptom is he reporting?Your Answer:
Correct Answer: Obsessions
Explanation:Understanding Psychiatric Symptoms: Obsessions, Compulsions, Delusions, Hallucinations, and Thought Interference
Psychiatric symptoms can be complex and difficult to understand. Here are some explanations of common symptoms:
Obsessions are intrusive thoughts, images, or impulses that repetitively and stereotypically enter a person’s mind. They are often distressing and patients try unsuccessfully to resist them. Common themes include aggression, dirt and contamination, fear of causing harm, religion, and sex.
Compulsions are repetitive and stereotyped acts or rituals that are often carried out as an attempt to neutralize distressing obsessional thoughts. Patients typically recognize these behaviors as pointless and ineffective, and try to resist them, often unsuccessfully.
Delusions are false, fixed, and firmly held beliefs that are not in keeping with a person’s social, cultural, and religious background. Patients typically do not recognize them as false or irrational and do not try to resist them, even if they find them distressing.
Hallucinations are sensory experiences that occur without an external stimulus that could produce such perception. They can be perceptions in any sensory modality, such as hearing a voice in the absence of anyone actually talking.
Thought interference consists of a patient’s firm belief that an external entity is interfering with their thoughts, usually by introducing thoughts in their mind, stealing thoughts from them, or being able to access their thoughts. Patients usually lack insight into these pathological experiences.
Understanding these symptoms can help individuals and their loved ones seek appropriate treatment and support.
