A 28-year-old female patient complains of experiencing difficulty sleeping for the past six months. She frequently stays awake at night due to worrying about work and family-related stressors. These episodes of anxiety are often accompanied by chest tightness and palpitations. Despite trying mindfulness, sleep hygiene, and reducing caffeine intake, she has not experienced significant improvement and is now considering medication. What would be the most suitable medication to prescribe?
Your Answer: Diazepam
Correct Answer: Sertraline
Explanation:Sertraline is the recommended first-line medication for generalised anxiety disorder (GAD). This is because the patient has already tried non-pharmacological measures with little benefit. Diazepam, a benzodiazepine, is not recommended due to the risk of tolerance and addiction. Duloxetine, a serotonin-norepinephrine reuptake inhibitor (SNRI), is not first-line but may be considered if the patient does not respond to sertraline. Mirtazapine, a noradrenergic and specific serotonergic antidepressant (NaSSA), is not generally recommended for GAD.
Anxiety is a common disorder that can manifest in various ways. According to NICE, the primary feature is excessive worry about multiple events associated with heightened tension. It is crucial to consider potential physical causes when diagnosing anxiety disorders, such as hyperthyroidism, cardiac disease, and medication-induced anxiety. Medications that may trigger anxiety include salbutamol, theophylline, corticosteroids, antidepressants, and caffeine.
NICE recommends a step-wise approach for managing generalised anxiety disorder (GAD). This includes education about GAD and active monitoring, low-intensity psychological interventions, high-intensity psychological interventions or drug treatment, and highly specialist input. Sertraline is the first-line SSRI for drug treatment, and if it is ineffective, an alternative SSRI or a serotonin-noradrenaline reuptake inhibitor (SNRI) such as duloxetine or venlafaxine may be offered. If the patient cannot tolerate SSRIs or SNRIs, pregabalin may be considered. For patients under 30 years old, NICE recommends warning them of the increased risk of suicidal thinking and self-harm and weekly follow-up for the first month.
The management of panic disorder also follows a stepwise approach, including recognition and diagnosis, treatment in primary care, review and consideration of alternative treatments, review and referral to specialist mental health services, and care in specialist mental health services. NICE recommends either cognitive behavioural therapy or drug treatment in primary care. SSRIs are the first-line drug treatment, and if contraindicated or no response after 12 weeks, imipramine or clomipramine should be offered.

A 63-year-old man presents to his general practitioner with stiffness in his muscles, difficulty initiating movements such as getting up from a chair, slow movements and hand shaking, which started 5 weeks ago. He has a medical history of schizophrenia and has had good compliance with his medication for the past 3 months. He is taking haloperidol. On examination, his temperature is 37.5 °C, blood pressure 120/81 mmHg and pulse 98 bpm. On examination, there is decreased facial expression, pill-rolling tremor, cogwheel rigidity and festinating gait.
Which of the following terms describes the symptoms of this patient?Your Answer: Akathisia
Correct Answer: Bradykinesia
Explanation:Common Neurological Side Effects of Medications
Medications can sometimes cause neurological side effects that mimic symptoms of neurological disorders. One such side effect is called pseudo-parkinsonism, which is characterized by bradykinesia or slowness in movements. This can be caused by typical and atypical antipsychotic medication, anti-emetics like metoclopramide, and some calcium channel blockers like cinnarizine.
Another side effect is acute dystonia, which is the sudden and sustained contraction of muscles in any part of the body, usually following the administration of a neuroleptic agent. Akathisia is another symptom associated with antipsychotic use, which is characterized by restlessness and the inability to remain motionless.
Tardive dyskinesia is a neurological side effect that is characterized by involuntary muscle movements, usually affecting the tongue, lips, trunk, and extremities. This is seen in patients who are on long-term anti-dopaminergic medication such as antipsychotic medication (both typical and atypical), some antidepressants, metoclopramide, prochlorperazine, carbamazepine, phenytoin, and others.
Finally, neuroleptic malignant syndrome is a life-threatening condition associated with the use of antipsychotic medication. It is characterized by hyperthermia, muscle rigidity, changes in level of consciousness, and autonomic instability. Management is supportive, and symptoms generally resolve within 1-2 weeks.

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

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

A 68-year-old woman visits her GP and complains of constant worrying, difficulty sleeping, and lack of focus on activities she used to enjoy. She is prescribed a new medication and referred for CBT. After a month, she returns to her GP feeling weak, lethargic, and experiencing muscle cramps. Her blood tests reveal the following results:
Sodium: 126 mmol/l (normal range: 135-145 mmol/l)
Potassium: 3.7 mmol/l (normal range: 3.5-5.0 mmol/l)
Creatinine: 95 µmol/l (normal range: 68-98 µmol/l)
Calcium: 2.40 mmol/l (normal range: 2.05-2.60 mmol/l)
Phosphate: 1.41 mmol/l (normal range: 0.8-1.50 mmol/l)
Which medication is most likely responsible for her symptoms?Your Answer: Sertraline
Explanation:Common Anxiety Medications and their Side Effects
Anxiety disorders are commonly treated with medication, and there are several options available. The first-line pharmacological treatment for anxiety is selective serotonin reuptake inhibitors (SSRIs) such as sertraline, paroxetine, or escitalopram. Alternatively, serotonin and norepinephrine reuptake inhibitors (SNRIs) like venlafaxine or duloxetine may be used. However, it is important to note that SSRIs can cause hyponatraemia, particularly in the elderly.
Diazepam is another medication used to treat anxiety, but it is not known to cause hyponatraemia. Its main side-effects are drowsiness and decreased concentration.
Pregabalin may be used if SSRIs or SNRIs are contraindicated or cannot be tolerated. It is not known to cause hyponatraemia.
Propranolol is a medication commonly used to treat high blood pressure, but it can also be used to treat anxiety. Its main side-effects are dizziness, fatigue, cold peripheries, insomnia, and nightmares. However, hyponatraemia is not a known side-effect of propranolol.
Finally, zopiclone may be prescribed for insomnia, but it is usually a short-term prescription and not given for more than four weeks due to the risk of withdrawal symptoms and tolerance. It is not known to cause hyponatraemia.
In summary, while there are several medications available to treat anxiety, it is important to be aware of their potential side-effects and to discuss any concerns with a healthcare provider.

Question 6
Correct

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

A 47-year-old woman presents complaining of ‘flashbacks’. Seven months earlier, she had been standing at a bus stop when a car swerved off the road into the queue, killing instantly a child standing near to her. Every day she experiences intrusive images of the child’s face as it saw the car mount the curb. She has not been able to go to that part of town since the day and she has avoided taking the bus anywhere. She feels she is always on edge and jumps at the slightest noise around the house. She thinks things are getting worse, rather than better, and asks you whether there are any psychological treatments that might help her.
Which one of the following approaches is indicated?Your Answer: Trauma-focused cognitive behavioural therapy (CBT)
Explanation:Treatment Options for Post-Traumatic Stress Disorder: Focus on Trauma-Focused CBT
Post-traumatic stress disorder (PTSD) is a delayed and/or prolonged response to a traumatic event that can cause distress in almost anyone. Symptoms include intrusive flashbacks, avoidance of trauma-related triggers, emotional numbness, and hypervigilance. Trauma-focused cognitive behavioural therapy (CBT) is the recommended first-line treatment for PTSD, according to the National Institute for Health and Care Excellence (NICE) in the United Kingdom. Other therapies, such as psychodynamic therapy, supportive therapy, and hypnotherapy, may be helpful but are not first-line approaches. Watchful waiting is only appropriate for mild symptoms present for less than a month. It is important to seek help for PTSD, and trauma-focused CBT is a proven effective treatment option.

A 32-year-old man comes to you seeking help as he feels like he is not himself lately. He has been struggling since his divorce 8 months ago. For the past 5 weeks, he has been experiencing low moods for most of the day, particularly in the mornings when he wakes up early. He has lost interest in his usual hobbies, including going to the gym. He has not been to any of his regular workout classes. He has had thoughts of taking a bottle of pills to end it all, but he knows he won't do it because he has a supportive family. He has no significant medical or psychiatric history.
Which of the following treatments would be the most appropriate?Your Answer: Fluoxetine
Explanation:Treatment Options for Depression: Choosing the Right Antidepressant
Depression is a serious mental health condition that requires a comprehensive treatment plan. Antidepressants are often prescribed as part of this plan, along with high-intensity psychological interventions like cognitive behavioural therapy (CBT). However, not all antidepressants are created equal. Here are some of the most commonly used antidepressants and their indications:
Fluoxetine: This selective serotonin reuptake inhibitor (SSRI) is the most suitable first-line treatment for depression due to its efficacy, patient acceptability, and lower toxicity in overdose.
Imipramine: This tricyclic antidepressant is not usually used as a first-line treatment for depression but has a role in nocturnal enuresis.
Lithium: While lithium has antidepressant properties, it is not a first-line treatment for unipolar depression due to its side-effects and the need for blood monitoring. It is commonly used in the treatment of bipolar affective disorder.
Electroconvulsive therapy (ECT): ECT is reserved for more severe depression where there is an immediate risk to life or where other treatments have been ineffective.
Phenelzine: This monoamine oxidase inhibitor (MAOI) is not commonly used as a first-line treatment for depression but is helpful in treatment-resistant depression.
It’s important to work closely with a healthcare professional to determine the best treatment plan for your individual needs. Antidepressants may take several weeks to take effect, and patients should be aware of potential side-effects and the importance of adhering to their medication regimen.

Sophie, a 22-year-old student, presents to her GP with a history of low mood lasting several months. She is struggling with her university studies due to poor concentration and constant fatigue. Despite waking up early every morning, she finds it difficult to fall back asleep. Sophie no longer enjoys spending time with her loved ones and feels hopeless about her future. She has sought medical attention as her symptoms are significantly impacting her academic performance.
Sophie denies having any suicidal thoughts, and there is no evidence of psychotic features during the examination. She is in good health and denies any alcohol or drug use. Sophie is eager to begin treatment for her symptoms. What would be the most appropriate course of action?Your Answer: A trial of fluoxetine
Explanation:Lucy is exhibiting symptoms typical of moderate/severe depression, including low mood, fatigue, anhedonia, difficulty concentrating, poor sleep, and feelings of hopelessness. According to NICE guidelines, the recommended first-line treatment for this level of depression is a combination of antidepressants and high-intensity psychological therapy, such as cognitive behavioural therapy or interpersonal therapy. As such, starting fluoxetine (an SSRI) would be the most appropriate course of action. Tricyclic antidepressants like amitriptyline are not recommended due to their potential side effects and overdose risk. Low-intensity psychological interventions like individual guided self-help are also not suitable for moderate/severe depression. While Lucy is not currently a risk to herself or others and is willing to try treatment in the community, urgent mental health review is not necessary. Given the severity of her symptoms and her desire for active treatment, watchful waiting is not recommended.
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 50-year-old woman presents with complaints of lower back pain, constipation, headaches, low mood, and difficulty concentrating. Which medication is most likely responsible for her symptoms?
Your Answer: Imipramine
Correct Answer: Lithium
Explanation:Hypercalcaemia, which is indicated by the presented signs and symptoms, can be a result of long-term use of lithium. The mnemonic ‘stones, bones, abdominal moans, and psychic groans’ can be used to identify the symptoms. The development of hyperparathyroidism and subsequent hypercalcaemia is believed to be caused by lithium’s effect on calcium homeostasis, leading to parathyroid hyperplasia. To diagnose this condition, a U&Es and PTH test can be conducted. Unlike lithium, other psychotropic medications are not associated with the development of hyperparathyroidism and hypercalcaemia.
Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.
Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

A mother brings her 10-year-old daughter who was recently diagnosed with attention-deficit/hyperactivity disorder (ADHD).
She is visiting the clinic as she is still having difficulty managing her daughter's disruptive and challenging behavior, despite receiving group-based support and environmental modifications.
What is the primary treatment option for managing ADHD?Your Answer: Methylphenidate
Explanation:Management of ADHD: First-Line Treatment and Other Options
Attention-deficit/hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects young people. While group-based support and environmental modifications can be helpful, medication and therapy are often necessary for ongoing, persistent impairment. Here are some options for managing ADHD:
First-Line Treatment: Methylphenidate
Methylphenidate is a central nervous system stimulant that is considered first-line treatment for young people with ADHD who still have significant symptoms despite other interventions. However, it is not approved for use in children under six years and requires monitoring of height, weight, heart rate, blood pressure, and ECG.Therapy: Cognitive Behavioural Therapy (CBT)
CBT can be helpful for patients who have already tried medication but continue to have significant symptoms. It can cover topics such as social skills, active listening, self-control, and expression of feelings.Alternative Medication: Dexamphetamine
Dexamphetamine is an option for patients who cannot tolerate or do not respond to methylphenidate. However, it is not first-line treatment.Not Recommended: Diazepam and Melatonin
Diazepam is not recommended for sedation in patients with ADHD. Melatonin can be used for regulating sleep in patients with learning difficulties, but it is not routinely used for ADHD management.In summary, ADHD management requires a tailored approach that may involve medication, therapy, or both. Methylphenidate is the first-line treatment, but other options are available for patients who do not respond or cannot tolerate it.

A 28-year-old new mum is seen by the midwife three days post-giving birth. She is tearful, has lost her appetite and worries she is a bad mother. Her midwife reassures her that this is most likely postpartum blues or ‘baby blues’.
What is the incidence of this condition in new mothers?Your Answer: 10-15%
Correct Answer: 50-75%
Explanation:Understanding Postpartum Mood Disorders: From Baby Blues to Postpartum Psychosis
Postpartum mood disorders are common among new mothers, but they can range from mild and transient to severe and potentially life-threatening. The most common form of postpartum mood disorder is postpartum blues, which affects an estimated 50-75% of mothers in the days following childbirth. Symptoms include crying, fatigue, anxiety, irritability, and labile mood, and typically last from hours to a few days. Postpartum blues is thought to be caused by hormonal changes in the body after labor and can be managed with supportive, non-pharmacological measures.
Postpartum depression is a more serious condition that can occur up to a year after birth and affects 10-15% of pregnancies. It is similar to major depression and requires screening by midwives and at the 6-week postnatal check. The Edinburgh Postnatal Depression Scale (EPDS) is a screening questionnaire used to identify women with postnatal depression, and it is important to follow up with mothers who may be depressed on a regular basis.
Postpartum psychosis is a rare but very serious mental health condition that usually develops in the days or weeks following childbirth and affects 0.1-0.5% of mothers. Symptoms may include mania, severe depression, hallucinations, abnormal behavior, and delusions. It is a medical emergency and typically requires inpatient psychiatric treatment.
Understanding the different types of postpartum mood disorders and their symptoms is crucial for healthcare providers to provide appropriate support and treatment for new mothers.

A 36-year-old man with a known history of severe depression has been in hospital for the past year. He was diagnosed with depression at the age of 23 and has been on antidepressants since. He has had multiple self-harm and suicide attempts in the past. For the past year, he has been receiving treatment in hospital and has been making some progress with regard to his mental health. He is not happy to be in hospital, but the doctors thought that it was in his best interests to keep him in hospital for treatment. He has been under a Section which allowed him to be kept in hospital for six months. At the end of the first six months, the doctors applied for a second time for him to be kept for another six months, as they feel he is not yet fit for discharge.
For how long can the relevant Section be renewed for this patient for the third time?Your Answer:
Correct Answer: One year
Explanation:Understanding the Time Limits of Mental Health Detention in the UK
In the UK, mental health detention is governed by specific time limits depending on the type of detention and the purpose of the detention. Here are some of the key time limits to be aware of:
– Section 2: This is the Section used for assessment, and a patient can be kept in hospital for a maximum of 28 days under this Section. It cannot be extended.
– Section 3: This is the Section used for treatment, and a patient can be detained for up to six months initially. The Section can be renewed for another six months, and then for one year at a time. Treatment without consent can be given for the first three months, and then only with the approval of an ‘approved second-opinion doctor’ for the next three months.
– Two years: While a patient can be kept in hospital for up to two years for treatment, Section 3 cannot be renewed for two years at a time. The patient can also be discharged earlier if the doctor thinks the patient is well enough.
– Six months: This is the time for which an initial Section 3 can be applied for and the time for which it can be renewed for a second time. For a third time and onwards, Section 3 can be renewed for one year each time, but the patient can be discharged earlier if doctors think it is not necessary for the patient to be under Section anymore.Understanding these time limits is important for both patients and healthcare professionals involved in mental health detention in the UK.

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

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

A 33-year-old woman who has never given birth before comes for her first prenatal visit at 29 weeks gestation. She is currently taking fluoxetine and lactulose and is concerned about the potential risks to her baby. What is a possible danger of using fluoxetine during the third trimester of pregnancy?
Your Answer:
Correct Answer: Persistent pulmonary hypertension
Explanation:When considering the use of SSRIs during pregnancy, it is important to assess the potential benefits and risks. While using SSRIs during the first trimester may slightly increase the risk of congenital heart defects, using them during the third trimester can lead to persistent pulmonary hypertension of the newborn. Additionally, paroxetine has a higher risk of congenital malformations, especially during the first trimester.
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.

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

A 42-year-old accountant comes to see you for a follow-up review 2 weeks after presenting with symptoms suggesting low mood. He had felt ‘down’ for several weeks, no longer enjoyed work or seeing friends and was sleeping more than usual. Despite this, he had a normal appetite, a strong sense of self-worth, denied any thoughts of self-harm or suicide and came across as reasonably active and lively. He says that he feels very anxious on Sunday evenings before going to work on a Monday and is getting increasingly ‘short and snappy’ with his colleagues. However, he says that work is otherwise going well and he is managing to get through the day. He does not feel any better at today’s consultation and is requesting advice about treatment options. He says he is ‘not a tablet person’.
What should you advise?Your Answer:
Correct Answer: A trial of computer-based cognitive behavioural therapy (CBT) or peer support
Explanation:For a patient with mild depression symptoms, the recommended first-line treatment is low-intensity psychosocial interventions such as computer-based CBT, group-based CBT, or peer support groups performing physical activity programs. If the patient prefers non-pharmacological treatment, antidepressants should not be used as first-line. Benzodiazepines should be avoided due to their addictive potential and side-effect profile. In the presence of both depression and anxiety, depression should be treated first according to NICE guidelines.

What is a positron emission tomography (PET) scan most likely to show?Your Answer:
Correct Answer: Hypoactivity of the prefrontal lobes, enlarged cerebral ventricles
Explanation:Brain Function and Psychiatric Disorders: PET Scan Findings
Major psychiatric syndromes, such as schizophrenia, mania, and depression, involve alterations in sensory processing, volitional behavior, environmental adaptation, and regulation of strong emotions. PET scans have shown that hypoactivity of the prefrontal lobes and enlarged cerebral ventricles are most likely to be associated with schizophrenia. On the other hand, hyperactivity of the prefrontal lobes is linked to obsessive-compulsive disorder (OCD). The prefrontal cortex plays a crucial role in planning, temporal sequencing, abstract thought, problem-solving, motility, attention, and the modulation of emotion. Lesions of these pathways impair pursuit of goal-oriented activity. PET scans have also revealed decreased metabolic activity in the temporal lobes in some patients with schizophrenia. However, increased occipital lobe activity is not likely to be seen on PET scans. Additionally, symmetrical enlargement of cerebral ventricles is a well-validated finding in patients suffering from schizophrenia.

Barbara, a 75-year-old recently widowed woman, visits your medical practice with her son, who is concerned about his mother's memory. Over the past few months, she has been forgetting appointments and conversations that they had just a few days ago, requiring frequent reminders to recall recent events. When you speak with Barbara, she mentions that she has lost her appetite and is waking up earlier than usual. She denies experiencing any hallucinations or issues with movement.
After administering a mini mental state exam, Barbara scores 23, and you observe that she is having difficulty focusing on your questions, often responding with I don't know.
What is the most probable diagnosis?Your Answer:
Correct Answer: Depression
Explanation:Depression and Alzheimer’s can have similar presentations in elderly patients, so it’s important to consider depression as a possible cause. Depression is a common issue among the elderly, and it can cause concentration problems that may be mistaken for memory loss.
There are several key symptoms that suggest depression, including loss of appetite, early morning wakening, poor concentration, and recent loss of a spouse. When conducting a mini mental state examination, patients with depression may respond with I don’t know, while those with Alzheimer’s may try to answer but give incorrect responses.
MMSE scores can help determine the severity of cognitive impairment, with scores of 24-30 indicating no impairment, 18-23 indicating mild impairment, and 0-17 indicating severe impairment.
Differentiating between Depression and Dementia
Depression and dementia are two conditions that can have similar symptoms, making it difficult to distinguish between the two. However, there are certain factors that can suggest a diagnosis of depression over dementia.
One of the key factors is the duration and onset of symptoms. Depression often has a short history and a rapid onset, whereas dementia tends to develop slowly over time. Additionally, biological symptoms such as weight loss and sleep disturbance are more commonly associated with depression than dementia.
Patients with depression may also express concern about their memory, but they are often reluctant to take tests and may be disappointed with the results. In contrast, patients with dementia may not be aware of their memory loss or may not express concern about it.
The mini-mental test score can also be variable in patients with depression, whereas in dementia, there is typically a global memory loss, particularly in recent memory.
In summary, while depression and dementia can have overlapping symptoms, careful consideration of the duration and onset of symptoms, biological symptoms, patient concerns, and cognitive testing can help differentiate between the two conditions.
