A 25-year-old woman returns to your clinic complaining of constant feelings of sadness, loss of appetite, insomnia, and a lack of enjoyment in anything. Despite making lifestyle changes and setting small goals, she still feels hopeless and requests medication. You decide to prescribe sertraline. What drug should be avoided in patients taking an SSRI?
Your Answer: Levothyroxine
Correct Answer: Sumatriptan
Explanation:Patients who are taking a SSRI should not use triptans.
Selective serotonin reuptake inhibitors (SSRIs) are commonly used as the first-line treatment for depression. Citalopram and fluoxetine are the preferred SSRIs, while sertraline is recommended for patients who have had a myocardial infarction. However, caution should be exercised when prescribing SSRIs to children and adolescents. Gastrointestinal symptoms are the most common side-effect, and patients taking SSRIs are at an increased risk of gastrointestinal bleeding. Patients should also be aware of the possibility of increased anxiety and agitation after starting a SSRI. Fluoxetine and paroxetine have a higher propensity for drug interactions.
The Medicines and Healthcare products Regulatory Agency (MHRA) has issued a warning regarding the use of citalopram due to its association with dose-dependent QT interval prolongation. As a result, citalopram and escitalopram should not be used in patients with congenital long QT syndrome, known pre-existing QT interval prolongation, or in combination with other medicines that prolong the QT interval. The maximum daily dose of citalopram is now 40 mg for adults, 20 mg for patients older than 65 years, and 20 mg for those with hepatic impairment.
When initiating antidepressant therapy, patients should be reviewed by a doctor after 2 weeks. Patients under the age of 25 years or at an increased risk of suicide should be reviewed after 1 week. If a patient responds well to antidepressant therapy, they should continue treatment for at least 6 months after remission to reduce the risk of relapse. When stopping a SSRI, the dose should be gradually reduced over a 4 week period, except for fluoxetine. Paroxetine has a higher incidence of discontinuation symptoms, including mood changes, restlessness, difficulty sleeping, unsteadiness, sweating, gastrointestinal symptoms, and paraesthesia.
When considering the use of SSRIs during pregnancy, the benefits and risks should be weighed. Use during the first trimester may increase the risk of congenital heart defects, while use during the third trimester can result in persistent pulmonary hypertension of the newborn. Paroxetine has an increased risk of congenital malformations, particularly in the first trimester.

Venlafaxine is an antidepressant that is commonly prescribed for the treatment of major depression, anxiety, and panic disorder. What is the most accurate description of the mechanism of action of this medication?
Your Answer: Serotonin and noradrenaline reuptake inhibitor
Explanation:The mechanism of action of venlafaxine involves inhibiting the reuptake of serotonin and noradrenaline, which leads to increased levels of these neurotransmitters in the synaptic space. This is why it is effective in treating depression, as it targets the alpha 2 receptors, noradrenaline, and serotonin.
Understanding Serotonin and Noradrenaline Reuptake Inhibitors
Serotonin and noradrenaline reuptake inhibitors (SNRIs) are a type of antidepressant medication that work by increasing the levels of serotonin and noradrenaline in the brain. These neurotransmitters are responsible for regulating mood, emotions, and anxiety levels. By inhibiting the reuptake of these chemicals, SNRIs help to maintain higher levels of serotonin and noradrenaline in the synaptic cleft, which can lead to improved mood and reduced anxiety.
Examples of SNRIs include venlafaxine and duloxetine, which are commonly used to treat major depressive disorders, generalised anxiety disorder, social anxiety disorder, panic disorder, and menopausal symptoms. These medications are relatively new and have been found to be effective in treating a range of mental health conditions. SNRIs are often preferred over other types of antidepressants because they have fewer side effects and are less likely to cause weight gain or sexual dysfunction.
Overall, SNRIs are an important class of medication that can help to improve the lives of people struggling with mental health conditions. By increasing the levels of serotonin and noradrenaline in the brain, these medications can help to regulate mood and reduce anxiety, leading to a better quality of life for those who take them.

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.

Question 4
Correct
-
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: 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.

You are a Foundation Year 2 doctor in Psychiatry. During the ward round, you are asked to perform a mental state examination of a patient who has been on the ward for a month.
In which part of the mental state examination would you report neologisms, pressure, or poverty?Your Answer: Speech
Explanation:Assessing Mental State: Key Components to Consider
When assessing a patient’s mental state, there are several key components to consider. These include speech rate, rhythm, and volume, as well as the presence of neologisms, which may indicate a thought disorder. Poverty of speech may suggest reduced speech content, often seen in depression, while pressure of speech may indicate an increased rate, often seen in mania.
Insight is another important factor to consider, as it reflects the patient’s understanding of their condition and their willingness to accept treatment. Under the heading of Appearance and behaviour, it is important to note the patient’s level of self-care, rapport, and any non-verbal cues. Abnormal movements and level of motor activity should also be observed.
Mood and affect are subjective and objective measures of the patient’s emotional state. Mood refers to the patient’s internal experience, while affect refers to the external manifestation of that emotion. Thought content should also be assessed, including any preoccupations, obsessions, overvalued ideas, ideas of reference, delusions, or suicidal thoughts. By considering these key components, clinicians can gain a comprehensive understanding of a patient’s mental state.

Question 6
Correct

A 35-year-old male comes to your clinic at the suggestion of his partner. He has been experiencing hyperarousal to loud noises and difficulty concentrating at work since his stay in the ICU 4 weeks ago. His partner believes he may have acute stress disorder, but you diagnose him with PTSD and discuss treatment options. He asks you to explain the difference between the two to his partner. You explain that while the presentation is similar, the main difference is temporal.
At what point after the event can you confirm a diagnosis of PTSD?Your Answer: 4 weeks
Explanation:Acute stress disorder is characterized by an acute stress reaction that occurs within four weeks of a traumatic event, while PTSD is diagnosed after four weeks have passed. Symptoms presented within two weeks would suggest acute stress disorder. Both acute stress disorder and PTSD share similar features, including re-experiencing, avoidance, hyperarousal, and emotional numbing. Re-experiencing symptoms may include flashbacks, nightmares, and repetitive and distressing intrusive images. Avoidance symptoms may involve avoiding people, situations, or circumstances associated with the traumatic event. Hyperarousal symptoms may include hypervigilance for threat, exaggerated startle response, sleep problems, irritability, and difficulty concentrating. Emotional numbing may result in a lack of ability to experience feelings and feeling detached.
Acute stress disorder is a condition that occurs within the first four weeks after a person has experienced a traumatic event, such as a life-threatening situation or sexual assault. It is characterized by symptoms such as intrusive thoughts, dissociation, negative mood, avoidance, and arousal. These symptoms can include flashbacks, nightmares, feeling disconnected from reality, and being hypervigilant.
To manage acute stress disorder, trauma-focused cognitive-behavioral therapy (CBT) is typically the first-line treatment. This type of therapy helps individuals process their traumatic experiences and develop coping strategies. In some cases, benzodiazepines may be used to alleviate acute symptoms such as agitation and sleep disturbance. However, caution must be taken when using these medications due to their addictive potential and potential negative impact on adaptation. Overall, early intervention and appropriate treatment can help individuals recover from acute stress disorder and prevent the development of more chronic conditions such as PTSD.

A 26-year-old man presents with complaints of hearing voices named ‘Tommy and Timmy’ who talk to him constantly. Initially, they would inquire about his activities, but lately, they have become derogatory, urging him to end his life and calling him worthless. Sometimes, they converse with each other about him, but he can still hear their unpleasant remarks. He seems frightened and bewildered. He is now convinced that Tommy and Timmy are the spirits of deceased children searching for another body to possess. The man's concerned sibling, who has accompanied him, reports that he has been experiencing these symptoms consistently for the past eight months. He is typically a reserved individual who never gets into trouble or uses drugs.
What is the most probable diagnosis for this man?Your Answer: Schizophrenia
Explanation:Understanding Schizophrenia: Differentiating it from Other Mental Health Disorders
Schizophrenia is a mental health disorder that can be diagnosed if certain criteria are met. These criteria include the presence of two or more symptoms such as delusions, hallucinations, disorganized speech, disorganized/catatonic behavior, or negative symptoms. At least one of the symptoms must be a positive symptom, and they must occur for a period of at least one month (less if treated) and be associated with a decline in functioning for at least six months. Additionally, symptoms cannot occur concurrently with substance use or a mood disorder episode.
In contrast to drug-induced psychosis, this man does not have a history of drug use. Mania, on the other hand, is a mood disorder characterized by predominantly positive feelings such as elation and euphoria. Schizoaffective disorder is diagnosed when there are both prominent psychotic and affective features, but this man does not have prominent affective symptoms. Delusional disorder, which is characterized by the development of a single or related delusions that are usually persistent and sometimes lifelong, does not include hallucinations.
In this case, the man is experiencing auditory hallucinations and delusions about the ghosts of dead children, which are typical symptoms of schizophrenia. Understanding the criteria for schizophrenia and differentiating it from other mental health disorders is crucial for accurate diagnosis and effective treatment.

A 39-year-old man, with a history of severe depression, is admitted unconscious to the hospital, following a suicide attempt where he stabbed himself with a knife, with significant intent of causing death. His past psychiatric history suggests that this is his fifth suicide attempt, with the four previous attempts involving taking an overdose of his antidepressants and paracetamol. During this admission, he needed surgery for bowel repair. He is now three days post-operation on the Surgical Ward and is having one-to-one nursing due to recurrent suicidal thoughts after his surgery. The consulting surgeon thinks he is not fit enough to be discharged, and a referral is made to liaison psychiatry. After assessing the patient, the psychiatrist reports that the patient’s current severe depression is affecting his capacity and that the patient’s mental health puts himself at risk of harm. The psychiatrist decides to detain him on the ward for at least three days. The patient insists on leaving and maintains that he has no interest to be alive.
Which is the most appropriate section for the doctor to use to keep this patient in hospital?Your Answer: Section 2
Correct Answer: Section 5(2)
Explanation:The Mental Health Act has several sections that allow doctors and mental health professionals to keep patients in hospital for assessment or treatment. Section 5(2) can be used by doctors to keep a patient in hospital for at least 72 hours if they have a history of severe depression, previous suicide attempts, or recurrent suicidal thoughts. Section 2 is used by approved mental health professionals for assessment and allows for a maximum stay of 28 days. Section 4 is used in emergencies and allows for a 72-hour stay. Section 5(4) can be used by mental health or learning disability nurses for a maximum of six hours. Section 3 can be used for treatment for up to six months, with the possibility of extensions and treatment against the patient’s will in the first three months.

A 25-year-old woman comes to her doctor's office seeking assistance for her anxiety. She feels overwhelmed by her job, particularly when it comes to communicating with coworkers and superiors, as she is afraid of being criticized. In her personal life, she frequently worries about how her friends perceive her and often avoids socializing with them as a result. She admits to having low self-esteem and a negative self-image. What is the most appropriate diagnosis for her?
Your Answer: Avoidant personality disorder
Explanation:Patients diagnosed with avoidant personality disorder exhibit a strong fear of criticism, rejection, ridicule, and being disliked. They tend to avoid social and occupational activities that involve significant interpersonal contact due to their fear of being criticized or rejected. These individuals have a negative self-image and are preoccupied with the idea that they are being criticized or rejected in social situations. Although they crave social contact, they tend to isolate themselves socially. This disorder is distinct from other personality disorders such as antisocial personality disorder, borderline personality disorder, and dependent personality disorder, which present with different symptoms and behaviors.
Personality disorders are a set of personality traits that are maladaptive and interfere with normal functioning in life. It is estimated that around 1 in 20 people have a personality disorder, which are typically categorized into three clusters: Cluster A, which includes Odd or Eccentric disorders such as Paranoid, Schizoid, and Schizotypal; Cluster B, which includes Dramatic, Emotional, or Erratic disorders such as Antisocial, Borderline (Emotionally Unstable), Histrionic, and Narcissistic; and Cluster C, which includes Anxious and Fearful disorders such as Obsessive-Compulsive, Avoidant, and Dependent.
Paranoid individuals exhibit hypersensitivity and an unforgiving attitude when insulted, a reluctance to confide in others, and a preoccupation with conspiratorial beliefs and hidden meanings. Schizoid individuals show indifference to praise and criticism, a preference for solitary activities, and emotional coldness. Schizotypal individuals exhibit odd beliefs and magical thinking, unusual perceptual disturbances, and inappropriate affect. Antisocial individuals fail to conform to social norms, deceive others, and exhibit impulsiveness, irritability, and aggressiveness. Borderline individuals exhibit unstable interpersonal relationships, impulsivity, and affective instability. Histrionic individuals exhibit inappropriate sexual seductiveness, a need to be the center of attention, and self-dramatization. Narcissistic individuals exhibit a grandiose sense of self-importance, lack of empathy, and excessive need for admiration. Obsessive-compulsive individuals are occupied with details, rules, and organization to the point of hampering completion of tasks. Avoidant individuals avoid interpersonal contact due to fears of criticism or rejection, while dependent individuals have difficulty making decisions without excessive reassurance from others.
Personality disorders are difficult to treat, but a number of approaches have been shown to help patients, including psychological therapies such as dialectical behavior therapy and treatment of any coexisting psychiatric conditions.

A 28-year-old woman presents to the emergency department with a decreased level of consciousness. Upon evaluation, her blood sugar is found to be 1.2 and is treated accordingly. The paramedics report finding her next to an insulin syringe, despite her not having diabetes. This is the third occurrence of such an event, and the patient denies any suicidal ideation. What is the diagnosis for this woman's condition?
Your Answer: Munchausen's syndrome
Explanation:Deliberately inducing symptoms, such as a diabetic intentionally overdosing on insulin to experience hypoglycemia, is an instance of Munchausen’s syndrome.
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 28-year-old patient presents to her doctor with symptoms of low mood and anhedonia. She has previously undergone cognitive behavioural therapy and art therapy, but with limited success. The doctor prescribes citalopram and refers her for additional talk therapy.
What medication should be avoided while taking citalopram?Your Answer: Rasagiline
Explanation:Combining SSRIs and MAOIs is not recommended due to the potential danger of developing serotonin syndrome.
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.

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: Tourette’s syndrome
Explanation:Understanding Tourette’s Syndrome: Symptoms and Treatment Options
Tourette’s syndrome is a neurological disorder that typically presents in childhood or adolescence. It is characterized by the presence of multiple motor tics and one or more vocal tics, which may not occur concurrently. The vocal tics can be throat-clearing, grunting, or other sounds that are not complete words or phrases. In some cases, there may also be associated gestural echopraxia, which can be of an obscene nature.
Schizophrenia, on the other hand, does not typically present with involuntary movements or tics. Conduct disorder is a mental disorder that is diagnosed before or after the age of 10 and is characterized by a persistent pattern of behavior that violates the basic rights of others or goes against age-developmental norms. Malingering is the fabrication of symptoms for some sort of secondary gain, while dissocial personality disorder is characterized by a long-term disregard for others or the violation of others.
Treatment options for Tourette’s syndrome include anti-psychotics such as pimozide, risperidone, and sulpiride, which have been shown to be effective. It is important to seek professional help if you or someone you know is experiencing symptoms of Tourette’s syndrome to receive an accurate diagnosis and appropriate treatment.

A 9-year-old patient is brought to the general practitioner by his parents because he has been disruptive at school. His teachers report that he does not pay attention in class, bullies other classmates and takes their food during lunchtime without their permission. One teacher also reported that the patient was seen hurting the class hamster.
What is the most probable diagnosis for this patient?Your Answer: Conduct disorder
Explanation:Differentiating between Conduct Disorder, Major Depression, Oppositional Defiant Disorder, Antisocial Disorder, and Manic Episode
Conduct Disorder, Major Depression, Oppositional Defiant Disorder, Antisocial Disorder, and Manic Episode are all mental health conditions that can present with similar symptoms. However, each disorder has its own unique characteristics that differentiate it from the others.
Conduct Disorder is a disorder that affects individuals under the age of 18 and is associated with disruptive, bullying behavior and often torture of animals. It is characterized by repetitive behavior that violates the rights of others.
Major Depression is associated with depressed mood, in addition to five of the following symptoms: sleep changes, loss of interest in previous hobbies or activities, guilt, decreased energy, difficulty concentrating, changes in appetite, sluggishness, and suicidal thoughts persisting for 2 weeks.
Oppositional Defiant Disorder is characterized by behavior in opposition to authority, but there is no violation of the rights of others or extreme behavior such as bullying or animal cruelty.
Antisocial Disorder is diagnosed in individuals who are 18 or older and exhibit signs of Conduct Disorder. It is characterized by a disregard for the rights of others and a lack of empathy.
Manic Episode is associated with elevated mood lasting for 7 days. These patients feel as though they have increased energy, do not need sleep, engage in risky sexual activity and sometimes illicit behavior, feel above the law or invincible, are easily distractible, have flight of fancy, are agitated, and have pressured speech.
It is important to differentiate between these disorders to ensure that individuals receive the appropriate treatment and support for their specific condition.

A 35-year-old male contacts his GP at 2PM to schedule his blood tests following a recent visit to his psychiatrist. The psychiatrist has raised his lithium dosage and requested that the GP arrange for lithium levels to be checked at the appropriate time after taking the medication. The patient took his first increased dose of lithium at 10AM (4 hours ago). In how many hours should the GP schedule the blood test to be taken?
Your Answer: 8 hours
Explanation: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.

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.

You are on a pediatric liaison rotation, and have been asked to talk to a 6-year-old patient with known ADHD. Upon trying to take a history from him, you struggle to follow his train of thought, as he keeps saying things like: 'I like pizza, it's so cheesy and easy -- my dog is brown, he likes to run around -- I have a blue pencil, it's my favorite utensil -'. You suspect that his thought process is characterized by rapid shifts from one idea to another without any apparent connection.
What is the medical term for this psychiatric symptom?Your Answer: Clang associations
Explanation:White kite, bright light, tight fight – these are examples of clang associations, where words are linked by their similar sounds or rhymes. It is a symptom often seen in individuals with schizophrenia or bipolar disorder. However, this patient is not currently displaying any signs of psychosis or mania. It is important to note that aphasic speech, where the patient loses the ability to form language, and echolalia, where they repeat words or phrases of others, are different from clang associations.
Thought disorders can manifest in various ways, including circumstantiality, tangentiality, neologisms, clang associations, word salad, Knight’s move thinking, flight of ideas, perseveration, and echolalia. Circumstantiality involves providing excessive and unnecessary detail when answering a question, but eventually returning to the original point. Tangentiality, on the other hand, refers to wandering from a topic without returning to it. Neologisms are newly formed words, often created by combining two existing words. Clang associations occur when ideas are related only by their similar sounds or rhymes. Word salad is a type of speech that is completely incoherent, with real words strung together into nonsensical sentences. Knight’s move thinking is a severe form of loosening of associations, characterized by unexpected and illogical leaps from one idea to another. Flight of ideas is a thought disorder that involves jumping from one topic to another, but with discernible links between them. Perseveration is the repetition of ideas or words despite attempts to change the topic. Finally, echolalia is the repetition of someone else’s speech, including the question that was asked.

You'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: Somatoform disorder
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.

Question 18
Correct

A 49-year-old man is brought to the emergency department after being found wandering the streets in an agitated state. His medical history includes hepatic steatosis, hypertension, and asthma, and he regularly takes amlodipine and Symbicort. He drinks up to 1 liter of vodka daily and has smoked for 30 years. He has not been seen by his family for 2-3 days before these events. His vital signs are heart rate 111 beats per minute, blood pressure 170/94 mmHg, respiratory rate 23 /min, oxygen saturations 97% on air, and temperature 37.2ºC. He is tremulous, diaphoretic, and agitated. Shortly after examination, he has a self-terminating seizure lasting 30 seconds. Blood tests and a CT head are performed, with the latter being reported as normal. What is the best medication choice to prevent further seizures?
Your Answer: Oral chlordiazepoxide
Explanation:Chlordiazepoxide is the preferred medication for treating delirium tremens and alcohol withdrawal, not diazepam. Symptoms of minor alcohol withdrawal, such as tremors, anxiety, and headaches, typically appear 6-12 hours after alcohol cessation and can progress to alcoholic hallucinosis, withdrawal seizures, and delirium tremens. Delirium tremens and alcohol withdrawal seizures are treated with chlordiazepoxide as the first-line medication. The Clinical Institute Withdrawal Assessment for Alcohol (CIWA) score is used to manage alcohol withdrawal in hospital, with benzodiazepines being administered based on the score. Intravenous glucose, intravenous hypertonic saline, and intravenous levetiracetam are not appropriate treatments for delirium tremens and alcohol withdrawal.
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.

Samantha, a 35-year-old woman, arrives at the emergency department complaining of severe, sharp pain on her left side that radiates to her lower abdomen and groin. The pain comes and goes in waves and has been ongoing for 10 hours. She also reports an increased frequency of urination and a burning sensation while urinating. A urine dip reveals haematuria but no signs of infection. You request the following blood tests:
Calcium 3.3 mmol/L (2.1-2.6)
Corrected Calcium 3.4 mmol/L (2.1-2.6)
Phosphate 0.6 mmol/L (0.8-1.4)
Magnesium 0.8 mmol/L (0.7-1.0)
Thyroid stimulating hormone (TSH) 4.9 mU/L (0.5-5.5)
Free thyroxine (T4) 9.5 pmol/L (9.0 - 18)
Parathyroid hormone 85 pg/mL (10-65 )
Which medication's long-term use is responsible for Samantha's condition?Your Answer: Clozapine
Correct Answer: Lithium
Explanation:Hyperparathyroidism and subsequent hypercalcaemia can occur with prolonged use of lithium. This can lead to the formation of kidney stones due to excessive calcium concentration. Amitriptyline, a sedative tricyclic antidepressant, is not likely to cause nephrolithiasis or explain the patient’s elevated calcium and parathyroid hormone levels. Similarly, clozapine, a second-generation antipsychotic, is not known to cause hypercalcaemia or hyperparathyroidism. Sertraline, a selective serotonin reuptake inhibitor, typically causes side effects during initiation or discontinuation, such as sexual dysfunction and gastrointestinal issues. Checking thyroid function tests may also be helpful as lithium use can lead to hypothyroidism.
Lithium is a medication used to stabilize mood in individuals with bipolar disorder and as an adjunct in treatment-resistant depression. It has a narrow therapeutic range of 0.4-1.0 mmol/L and is primarily excreted by the kidneys. The mechanism of action is not fully understood, but it is believed to interfere with inositol triphosphate and cAMP formation. Adverse effects may include nausea, vomiting, diarrhea, fine tremors, nephrotoxicity, thyroid enlargement, ECG changes, weight gain, idiopathic intracranial hypertension, leucocytosis, hyperparathyroidism, and hypercalcemia.
Monitoring of patients taking lithium is crucial to prevent adverse effects and ensure therapeutic levels. It is recommended to check lithium levels 12 hours after the last dose and weekly after starting or changing the dose until levels are stable. Once established, lithium levels should be checked every three months. Thyroid and renal function should be monitored every six months. Patients should be provided with an information booklet, alert card, and record book to ensure proper management of their medication. Inadequate monitoring of patients taking lithium is common, and guidelines have been issued to address this issue.

A 22-year old woman comes to see her GP, seeking medication for opioid withdrawal. She explains that she has been using heroin for the past six months since losing her job as a store manager. She informs the GP that she has decided to quit using heroin and has not taken any for the past three days. She reports experiencing severe withdrawal symptoms that have been affecting her daily life and asks if there is anything that can be prescribed to alleviate her symptoms.
What are the observable indications of opioid withdrawal?Your Answer: Dilated pupils, yawning, rhinorrhoea, epiphora
Explanation:Identifying Objective Signs of Opioid Withdrawal and Intoxication
It is crucial to recognize objective signs of opioid withdrawal and intoxication to prevent fatal outcomes. In psychiatric settings, individuals may falsely claim withdrawal to obtain opioid medications. Objective signs of withdrawal include epiphora, rhinorrhoea, agitation, perspiration, piloerection, tachycardia, vomiting, shivering, yawning, and dilated pupils. Pinpoint pupils, yawning, and galactorrhoea are indicative of opiate intoxication. Respiratory depression is a feature of opioid intoxication, along with pinpoint pupils and bradycardia. Opioid intoxication can also cause pulmonary oedema, stupor, pallor, severe respiratory depression, and nausea. By recognizing these objective signs, healthcare professionals can accurately diagnose and treat opioid withdrawal and intoxication.

You are evaluating a 22-year-old male with depression who has had limited success with various antidepressants and counseling. You opt to initiate a trial of mirtazapine. What side effect of this antidepressant can you advise him is a common feature?
Your Answer: Increase in appetite
Explanation:Mirtazapine is an effective antidepressant that works by blocking alpha-2 receptors, but it often causes unwanted side effects such as increased appetite and sedation, which can make it difficult for patients to tolerate. On the other hand, MAOI antidepressants like phenelzine can cause a dangerous reaction when consuming foods high in tyramine, such as cheese, leading to a hypertensive crisis. While tardive dyskinesia is typically associated with typical antipsychotics, it can rarely occur as a result of some antidepressants. It’s worth noting that headache is a common withdrawal symptom of mirtazapine, rather than a side effect during its use.
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 60-year-old patient with a history of bipolar disorder visits your GP clinic for routine blood tests. Despite feeling completely fine, he wants to check his health status. Upon clinical examination, there are no signs of splenomegaly or lymphadenopathy.
The following are the results:
- Hb 140 g/L Male: (135-180) Female: (115 - 160)
- Platelets 160 * 109/L (150 - 400)
- WBC 14 * 109/L (4.0 - 11.0)
- Na+ 144 mmol/L (135 - 145)
- K+ 4.7 mmol/L (3.5 - 5.0)
- Urea 5.4 mmol/L (2.0 - 7.0)
- Creatinine 114 µmol/L (55 - 120)
- Thyroid stimulating hormone (TSH) 5.2 mU/L (0.5-5.5)
- Free thyroxine (T4) 9.5 pmol/L (9.0 - 18)
- Lithium level 0.75 mmol/L (0.6 - 1.2)
What advice would you give to this patient?Your Answer: Safety net to return if symptoms develop, arrange repeat blood tests as per usual, under the normal monitoring schedule
Explanation:Lithium, a mood-stabilizing drug commonly used in bipolar disorder, can lead to various health complications such as thyroid, cardiac, renal, and neurological issues. One of the common side effects of lithium is benign leucocytosis, which is also associated with other drugs like corticosteroids and beta-blockers. In this case, it is appropriate to continue with the normal monitoring schedule and safety netting for any signs of infection or malignancy, as there are no indications of either. Antibiotics would not be necessary. Malignant leucocytosis is unlikely as there are no accompanying symptoms such as night sweats, weight loss, bleeding, lymphadenopathy, or bone pain. Withholding lithium would not be advisable as it is effectively managing the patient’s condition. The psychiatric team should be consulted before making any decisions regarding the medication.

Question 23
Correct

A 67-year-old male who has been on long term chlorpromazine presents with repetitive eye blinking. He is concerned about the cause of this symptom and reports being unable to control it. He has no visual disturbance and is otherwise in good health. Upon examination, he has a normal facial and ocular appearance except for excessive rapid blinking. What is the probable reason for his symptoms?
Your Answer: Tardive dyskinesia
Explanation:The correct term for the condition described in the stem is tardive dyskinesia. This is a late onset side effect of conventional antipsychotics, such as chlorpromazine, which causes abnormal involuntary movements. Patients may exhibit symptoms such as lip-smacking, jaw pouting, chewing, or repetitive blinking. Unfortunately, this condition is often difficult to treat, but replacing the antipsychotic or trying tetrabenazine may provide some relief.
Parkinsonism is another potential side effect of conventional antipsychotics, but it presents with symptoms similar to Parkinson’s disease, such as tremors, blank facies, bradykinesia, and muscle rigidity. Dry eyes or Sjogren’s syndrome may cause eye twitching, but they are unlikely to cause repetitive blinking. Blepharospasm is a condition characterized by involuntary twitching or contraction of the eyelid, which may be caused by stress or fatigue. However, given the patient’s use of chlorpromazine, tardive dyskinesia is the most likely diagnosis.
Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. They are associated with extrapyramidal side-effects and hyperprolactinaemia, which are less common with atypical antipsychotics.
Extrapyramidal side-effects (EPSEs) are common with typical antipsychotics and include Parkinsonism, acute dystonia, sustained muscle contraction, akathisia, and tardive dyskinesia. The latter is a late onset of choreoathetoid movements that may be irreversible and occur in 40% of patients. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients, including an increased risk of stroke and venous thromboembolism. Other side-effects include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval.

A 67-year-old man presents to the hospital in a confused state. He is unable to explain his condition but insists that he was admitted for 10 days last month despite records showing his last admission to be 7 months ago. He cannot recall which secondary school he attended and, after being on the ward for a week, he does not recognize his primary doctor's face. The patient has a medical history of hypertension, ischemic stroke, and alcoholic liver disease.
Upon examination, the patient has normal tone, upgoing plantar reflexes on the right, and a broad-based gait. There are bilateral cranial nerve 6 (CN 6) palsies associated with nystagmus.
What is the probable diagnosis for this patient?Your Answer: Vascular dementia
Correct Answer: Korsakoff's syndrome
Explanation:Korsakoff’s syndrome is a complication that can arise from Wernicke’s encephalopathy, and it is characterized by anterograde amnesia, retrograde amnesia, and confabulation. In this case, the patient displays confusion, ataxia, and ophthalmoplegia, as well as anterograde and retrograde amnesia with confabulation, which suggests that they have progressed to Korsakoff’s syndrome. Wernicke’s encephalopathy is caused by a deficiency in thiamine (vitamin B1), which is often due to chronic alcohol abuse or malnutrition. It presents with confusion, ataxia, and oculomotor dysfunction, which can lead to Korsakoff’s syndrome if left untreated. Brain tumors typically present with symptoms of increased intracranial pressure and focal neurological deficits, which are not present in this case. Lewy body dementia can be diagnosed if a patient with decreased cognition displays two or more of the following symptoms: parkinsonism, visual hallucinations, waxing-and-waning levels of consciousness, and rapid-eye-movement (REM) sleep behavior disorder. Transient global amnesia is a temporary condition that involves retrograde and anterograde amnesia following a stressful event, lasting between 2-8 hours but less than 24 hours. Based on the patient’s symptoms and history of alcohol abuse, Korsakoff’s syndrome is the most likely diagnosis.
Understanding Korsakoff’s Syndrome
Korsakoff’s syndrome is a memory disorder that is commonly observed in individuals who have a history of alcoholism. The condition is caused by a deficiency of thiamine, which leads to damage and bleeding in the mammillary bodies of the hypothalamus and the medial thalamus. Korsakoff’s syndrome often develops after untreated Wernicke’s encephalopathy.
The symptoms of Korsakoff’s syndrome include anterograde amnesia, which is the inability to form new memories, and retrograde amnesia. Individuals with this condition may also experience confabulation, which is the production of fabricated or distorted memories to fill gaps in their recollection.

A teenager has been referred because of bizarre behaviour at school. His teachers have reported that he alternates between very passive and very aggressive behaviours. At times, he cries and withdraws from sight when he thinks he is being slighted in some manner. At other times, he yells wildly and fights over the smallest of infractions. Upon further examination, you discover that the patient has been the victim of significant abuse at home.
Which one of the following defence mechanisms is he likely employing?Your Answer: Splitting
Correct Answer: Dissociation
Explanation:Understanding Ego Defense Mechanisms: Dissociation, Sublimation, Identification, Reaction Formation, and Splitting
Ego defense mechanisms are psychological strategies that individuals use to cope with stressful situations. These mechanisms can be either mature or immature, depending on their effectiveness and adaptability. Here are some examples of common ego defense mechanisms and how they manifest in individuals:
Dissociation: This is an immature defense mechanism where a person temporarily modifies their personal identity to avoid distress. For instance, a victim of abuse may develop multiple personalities to cope with the trauma.
Sublimation: This is a mature defense mechanism where a person takes an unacceptable personality trait and channels it into a respectable work that aligns with their values. For example, a person with aggressive tendencies may become a successful athlete.
Identification: This is when a person models the behavior of a more powerful figure. For instance, a victim of child abuse may become a child abuser in adulthood.
Reaction Formation: This is an immature defense mechanism where a person represses unacceptable emotions and replaces them with their exact opposite. For example, a man with homoerotic desires may champion anti-homosexual public policy.
Splitting: This is an immature defense mechanism where a person is unable to reconcile both good and bad traits in a given person and sees people as either all good or all bad.
Understanding these defense mechanisms can help individuals recognize and address maladaptive coping strategies and work towards healthier ways of dealing with stress.

A 20-year-old individual presents with obsessive thoughts about causing harm to others since moving away from home to attend college. They are particularly anxious about using the shared kitchen in their dormitory and tend to prepare and eat meals during the night to avoid contact with their roommates. After completing a Yale-Brown Obsessive Compulsive Scale (Y-BOCS), they are diagnosed with mild OCD. What treatment option would be most suitable for this individual?
Your Answer: Cognitive behavioural therapy
Explanation:For patients with mild symptoms of obsessive-compulsive disorder (OCD) and mild impairment, the recommended first-line treatment is cognitive behavioural therapy (CBT) with exposure and response prevention (ERP). While clomipramine, a tricyclic antidepressant, may be used in some cases, it is not typically the first choice. Dialectical behaviour therapy is not commonly used in the treatment of OCD, as CBT and ERP are more effective. Fluoxetine, an SSRI antidepressant, may also be used in the treatment of OCD, but is not typically the first-line treatment for mild cases.
Obsessive-compulsive disorder (OCD) is characterized by the presence of obsessions and/or compulsions that can cause significant functional impairment and distress. Risk factors include family history, age, pregnancy/postnatal period, and history of abuse, bullying, or neglect. Treatment options include low-intensity psychological treatments, SSRIs, and more intensive CBT (including ERP). Severe cases should be referred to the secondary care mental health team for assessment and may require combined treatment with an SSRI and CBT or clomipramine as an alternative. ERP involves exposing the patient to an anxiety-provoking situation and stopping them from engaging in their usual safety behavior. Treatment with SSRIs should continue for at least 12 months to prevent relapse and allow time for improvement.

A 40-year-old woman was admitted to the psychiatric ward with paranoid delusions, auditory hallucinations and violent behaviour. There was no past medical history. She was diagnosed with schizophrenia and given intramuscular haloperidol regularly. Four days later, she became febrile and confused. The haloperidol was stopped, but 2 days later, she developed marked rigidity, sweating and drowsiness. She had a variable blood pressure and pulse rate. Creatine phosphokinase was markedly raised.
What is the most likely diagnosis?Your Answer: Neuroleptic malignant syndrome
Explanation:Understanding Neuroleptic Malignant Syndrome: A Potentially Life-Threatening Reaction to Neuroleptic Medication
Neuroleptic malignant syndrome (NMS) is a rare but serious reaction to neuroleptic medication. It is characterized by hyperpyrexia (high fever), autonomic dysfunction, rigidity, altered consciousness, and elevated creatine phosphokinase levels. Treatment involves stopping the neuroleptic medication and cooling the patient. Medications such as bromocriptine, dantrolene, and benzodiazepines may also be used.
It is important to note that other conditions, such as cerebral abscess, meningitis, and phaeochromocytoma, do not typically present with the same symptoms as NMS. Serotonin syndrome, while similar, usually presents with different symptoms such as disseminated intravascular coagulation, renal failure, tachycardia, hypertension, and tachypnea.
If you or someone you know is taking neuroleptic medication and experiences symptoms of NMS, seek medical attention immediately. Early recognition and treatment can be life-saving.

Which statement about the causation and dynamics of schizophrenia is accurate?
Your Answer: Schizophrenia is commoner in individuals not in stable relationships
Explanation:Schizophrenia Risk Factors
Schizophrenia is a mental disorder that affects a person’s ability to think, feel, and behave clearly. The risk of developing schizophrenia is influenced by various factors, including heavy cannabis use, marital status, socioeconomic status, and genetics.
According to the Swedish conscript study, heavy cannabis users have a sevenfold increase in the risk of developing schizophrenia. However, it is unclear whether cannabis use directly causes schizophrenia or if there are other underlying factors at play.
Marital status also appears to be a factor in schizophrenia risk, with unmarried and divorced individuals being twice as likely to develop the disorder compared to married or widowed individuals. This may be due to the alienating effects of schizophrenia rather than any causal relationship with being single.
Additionally, people with schizophrenia are more likely to be in the lowest socioeconomic groups. While poverty may not directly cause schizophrenia, it may increase the risk of exposure to biological factors or social stressors that could trigger the illness in susceptible individuals.
Finally, genetics also play a significant role in schizophrenia risk, with monozygotic twins having a 50% concordance rate and 10% of offspring being affected. This suggests a strong inheritance component to the disorder.
Overall, while the exact causes of schizophrenia are not fully understood, it is clear that multiple factors contribute to its development.

A 37-year-old man presents with intrusive images of a violent altercation he witnessed a couple of months ago. He says he cannot concentrate because of it and has been avoiding going to the area where it happened. What should be your first line in management?
Your Answer: Trauma-focused cognitive behavioural therapy (CBT)
Explanation:Treatment Options for Post-Traumatic Stress Disorder (PTSD)
Post-traumatic stress disorder (PTSD) is characterized by repetitive, intrusive recollection or re-enactment of a traumatic event in memories, daytime imagery, or dreams. Other symptoms include emotional detachment, numbing of feeling, and avoidance of stimuli that might arouse recollection of the trauma. If symptoms are mild and occur within four weeks of the trauma, watchful waiting is appropriate. However, if symptoms are severe or persist beyond this time, psychological interventions should be considered as first-line treatments.
Trauma-focused cognitive behavioural therapy (CBT) is the recommended treatment for PTSD. Eye movement desensitisation and reprocessing (EMDR) is an alternative for those whose symptoms have persisted for three months beyond the trauma. Pharmacological interventions, such as paroxetine and mirtazapine, are considered second line but may be given first to those who express a preference.
Dynamic psychotherapy, which relies on the relationship between the patient and the psychotherapist, is not used as first-line treatment for PTSD but is considered the treatment of choice for adjustment disorder.

A 42-year-old woman visits her GP with her husband, reporting that she has been experiencing a racing heart for the past year. She also feels sweaty and sometimes has difficulty breathing. Despite seeing a cardiologist, no abnormalities were found in her heart. The patient admits to worrying about various things, which has affected her relationships with her loved ones. She also suffers from insomnia 3-4 nights a week. The patient has no significant medical history, but her cousin has a history of depression. On examination, the patient's heart rate is 89 bpm, and her palms are sweaty. Blood tests show no abnormalities, including normal thyroid function and calcium levels. Which neuroendocrine axis is involved in the patient's condition?
Your Answer: Hypothalamic–pituitary–adrenal (HPA)
Explanation:The Role of Hypothalamic-Pituitary Axes in Health and Disease
The hypothalamic-pituitary axes play a crucial role in maintaining homeostasis in the body. Among these axes, the hypothalamic-pituitary-adrenal (HPA) axis is particularly important in the pathophysiology of anxiety disorders. Overactivation of the HPA axis leads to the release of catecholamines, resulting in the fight or flight response. Environmental factors and genetics may contribute to the development of anxiety disorders, but the final common pathway is the dysregulation of the HPA axis.
The hypothalamic-pituitary-thyroid (HPT) axis is involved in thyroid disorders, such as hyperthyroidism and hypothyroidism. However, normal thyroid function rules out this axis as a cause of the patient’s symptoms.
The hypothalamic-pituitary-gonadal (HPG) axis is responsible for the release of sex hormones, such as oestrogen and testosterone. Disorders affecting the HPG axis can impact puberty and sexual development.
The hypothalamic-pituitary-prolactin (HPP) axis regulates the release of prolactin, which acts on the mammary glands. Medications can cause dysregulation of the HPP axis, resulting in hyperprolactinaemia or hypoprolactinaemia.
Finally, the hypothalamic-pituitary-somatotropic (HPS) axis is involved in the release of growth hormone and insulin-like growth factor 1. Dysregulation of the HPS axis can lead to growth hormone deficiency and Laron syndrome.
Understanding the role of these hypothalamic-pituitary axes is crucial in diagnosing and treating various health conditions.
