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

Question 2
Correct

As a junior doctor in General Practice, you come across a 27-year-old woman who is worried about her declining work performance. Her boss has labeled her as 'neurotic' due to her frequent missing of deadlines. She identifies herself as a 'perfectionist' and is unable to comprehend why this is happening. She has always found solace in keeping her workspace clean and organized and struggles to handle situations where she is not in control, especially at work. She recalls being an anxious child but has never sought help from a psychiatrist. What is the most probable cause of her difficulties?
Your Answer: Obsessive compulsive personality disorder
Explanation:The individual in question is exhibiting symptoms of anankastic personality disorder, also known as obsessive-compulsive personality disorder (OCPD). This disorder is characterized by a preoccupation with orderliness, perfectionism, and an excessive focus on details, as well as a need for control over one’s environment and interpersonal relationships. However, this often comes at the expense of flexibility, openness to new experiences, and efficiency. Unlike obsessive-compulsive disorder (OCD), where thoughts and behaviors are seen as unwanted and unhealthy, those with OCPD view their behaviors as rational and desirable. This can lead to difficulty completing tasks, as the individual becomes overly focused on perfectionism and attention to detail. Generalized anxiety disorder is less likely to be the diagnosis in this case, as the individual’s worries are specific to work-related issues. Schizoid personality disorder, on the other hand, is characterized by a lack of interest in forming close relationships with others and a preference for solitude. These individuals may appear cold and uninterested in intimacy or pleasure from life.
Personality disorders are a set of personality traits that are maladaptive and interfere with normal functioning in life. It is estimated that around 1 in 20 people have a personality disorder, which are typically categorized into three clusters: Cluster A, which includes Odd or Eccentric disorders such as Paranoid, Schizoid, and Schizotypal; Cluster B, which includes Dramatic, Emotional, or Erratic disorders such as Antisocial, Borderline (Emotionally Unstable), Histrionic, and Narcissistic; and Cluster C, which includes Anxious and Fearful disorders such as Obsessive-Compulsive, Avoidant, and Dependent.
Paranoid individuals exhibit hypersensitivity and an unforgiving attitude when insulted, a reluctance to confide in others, and a preoccupation with conspirational beliefs and hidden meanings. Schizoid individuals show indifference to praise and criticism, a preference for solitary activities, and emotional coldness. Schizotypal individuals exhibit odd beliefs and magical thinking, unusual perceptual disturbances, and inappropriate affect. Antisocial individuals fail to conform to social norms, deceive others, and exhibit impulsiveness, irritability, and aggressiveness. Borderline individuals exhibit unstable interpersonal relationships, impulsivity, and affective instability. Histrionic individuals exhibit inappropriate sexual seductiveness, a need to be the center of attention, and self-dramatization. Narcissistic individuals exhibit a grandiose sense of self-importance, lack of empathy, and excessive need for admiration. Obsessive-compulsive individuals are occupied with details, rules, and organization to the point of hampering completion of tasks. Avoidant individuals avoid interpersonal contact due to fears of criticism or rejection, while dependent individuals have difficulty making decisions without excessive reassurance from others.
Personality disorders are difficult to treat, but a number of approaches have been shown to help patients, including psychological therapies such as dialectical behavior therapy and treatment of any coexisting psychiatric conditions.

Question 3
Correct

Which one of the following is not an example of an atypical antipsychotic medication?
Your Answer: Flupentixol
Explanation:Atypical antipsychotics are now recommended as the first-line treatment for patients with schizophrenia, as per the 2005 NICE guidelines. These medications have the advantage of significantly reducing extrapyramidal side-effects. However, they can also cause adverse effects such as weight gain, hyperprolactinaemia, and in the case of clozapine, agranulocytosis. The Medicines and Healthcare products Regulatory Agency has issued warnings about the increased risk of stroke and venous thromboembolism when antipsychotics are used in elderly patients. Examples of atypical antipsychotics include clozapine, olanzapine, risperidone, quetiapine, amisulpride, and aripiprazole.
Clozapine, one of the first atypical antipsychotics, carries a significant risk of agranulocytosis and requires full blood count monitoring during treatment. Therefore, it should only be used in patients who are resistant to other antipsychotic medication. The BNF recommends introducing clozapine if schizophrenia is not controlled despite the sequential use of two or more antipsychotic drugs, one of which should be a second-generation antipsychotic drug, each for at least 6-8 weeks. Adverse effects of clozapine include agranulocytosis, neutropaenia, reduced seizure threshold, constipation, myocarditis, and hypersalivation. Dose adjustment of clozapine may be necessary if smoking is started or stopped during treatment.

You are a foundation year two doctor on a placement in older adult mental health. You have been caring for an 81-year-old gentleman with bipolar disorder who is being held under the mental health act. He develops fever, cough productive of green sputum and tachycardia and is admitted to the local hospital where he dies of pneumonia. Your consultant, trained in psychiatry with no recent experience in general medicine, asks what the next step will be with regards to the death certificate. What is the appropriate next step for completing the death certificate - who would complete it and what would be the cause of death?
Your Answer: You will complete it putting pneumonia in part 1a
Correct Answer: The case will be referred to the coroner
Explanation:If a person passes away while under the mental health act, it is mandatory to report their death to the coroner, regardless of the cause. Therefore, neither the individual nor the acute hospital doctors who complete the certificate should be the first to report the case. Although reporting to the coroner is necessary, a post mortem examination is unlikely to take place. It is not permissible to list old age as the cause of death on the certificate if the patient is under the age of 80.
Sectioning under the Mental Health Act is a legal process used for individuals who refuse voluntary admission. This process excludes patients who are under the influence of drugs or alcohol. There are several sections under the Mental Health Act that allow for different types of admission and treatment.
Section 2 allows for admission for assessment for up to 28 days, which is not renewable. An Approved Mental Health Professional (AMHP) or the nearest relative (NR) can make the application on the recommendation of two doctors, one of whom should be an approved consultant psychiatrist. Treatment can be given against the patient’s wishes.
Section 3 allows for admission for treatment for up to 6 months, which can be renewed. An AMHP and two doctors, both of whom must have seen the patient within the past 24 hours, can make the application. Treatment can also be given against the patient’s wishes.
Section 4 is used as an emergency 72-hour assessment order when a section 2 would involve an unacceptable delay. A GP and an AMHP or NR can make the application, which is often changed to a section 2 upon arrival at the hospital.
Section 5(2) allows a doctor to legally detain a voluntary patient in hospital for 72 hours, while section 5(4) allows a nurse to detain a voluntary patient for 6 hours.
Section 17a allows for Supervised Community Treatment (Community Treatment Order) and can be used to recall a patient to the hospital for treatment if they do not comply with the conditions of the order in the community, such as taking medication.
Section 135 allows for a court order to be obtained to allow the police to break into a property to remove a person to a Place of Safety. Section 136 allows for someone found in a public place who appears to have a mental disorder to be taken by the police to a Place of Safety. This section can only be used for up to 24 hours while a Mental Health Act assessment is arranged.

A patient with a history of depression at the age of 50 presents for review. What indicates an elevated risk of suicide?
Your Answer: History of arm cutting
Explanation:Arm cutting may be seen as attention-seeking or a way to release pain, but studies indicate that it increases the risk of suicide for those with a history of deliberate self harm. Employment is a protective factor.
Suicide Risk Factors and Protective Factors
Suicide risk assessment is a common practice in psychiatric care, with patients being stratified into high, medium, or low risk categories. However, there is a lack of evidence on the positive predictive value of individual risk factors. A review in the BMJ concluded that such assessments may not be useful in guiding decision-making, as 50% of suicides occur in patients deemed low risk. Nevertheless, certain factors have been associated with an increased risk of suicide, including male sex, history of deliberate self-harm, alcohol or drug misuse, mental illness, depression, schizophrenia, chronic disease, advancing age, unemployment or social isolation, and being unmarried, divorced, or widowed.
If a patient has attempted suicide, there are additional risk factors to consider, such as efforts to avoid discovery, planning, leaving a written note, final acts such as sorting out finances, and using a violent method. On the other hand, there are protective factors that can reduce the risk of suicide, such as family support, having children at home, and religious belief. It is important to consider both risk and protective factors when assessing suicide risk and developing a treatment plan.

You assess a 50-year-old woman who has developed a dependence on temazepam, which was initially prescribed as a sleep aid. She expresses a desire to overcome her addiction to temazepam and seeks assistance. Her current dosage is 20 mg per day. What would be the most suitable approach?
Your Answer: Switch to the equivalent diazepam dose then slowly withdraw over the next 2 weeks
Correct Answer: Switch to the equivalent diazepam dose then slowly withdraw over the next 2 months
Explanation:Benzodiazepines are drugs that enhance the effect of the neurotransmitter GABA, which inhibits brain activity. They are used for various purposes, including sedation, anxiety relief, muscle relaxation, and seizure prevention. However, patients can develop a tolerance and dependence on these drugs, so they should only be prescribed for a short period of time. When withdrawing from benzodiazepines, it is important to do so gradually to avoid withdrawal symptoms, which can include insomnia, anxiety, and seizures. Barbiturates are another type of drug that affect GABA, but they work differently than benzodiazepines by increasing the duration of chloride channel opening.

Question 7

A 25-year-old football player comes to the GP clinic complaining of a loss of motor function in his left leg. He denies any specific injuries and has an important game next week that he's been anxious about. He enters the room using crutches. During the examination, it is found that he has 0/5 power in his left knee, ankle, and toes. The rest of the neurological and musculoskeletal examination is unremarkable. Blood tests and a lumbar MRI come back normal, making an organic cause for his symptoms unlikely. He is eager to know the reason behind his condition so that he can resume his training.
What is the most probable cause of his symptoms?Your Answer: Factitious disorder
Correct Answer: Conversion disorder
Explanation:It is probable that the patient is experiencing conversion disorder, which is often triggered by stress and involves the loss of motor or sensory function. The potential grand final rugby game may have been the stressor in this case.
Somatisation disorder is unlikely as it requires the presence of multiple physical symptoms for at least two years, whereas this patient has only one acute onset symptom. Dissociative disorder is also improbable as there are no evident psychiatric symptoms such as amnesia, stupor, or fugue. The patient remembers clearly that he has a football game and has not sustained any recent injuries.
However, factitious disorder cannot be ruled out entirely. It is possible that the patient is feigning the symptom to avoid playing the game, but further investigation is necessary. The patient claims to be eager to return to playing, which does not support the notion of factitious disorder.
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 30-year-old female arrives at the Emergency Department complaining of eye pain and an unusual posture. During the examination, it is observed that her neck is fixed in a backward and lateral position, and her eyes are deviated upwards. She is unable to control her gaze. The patient has a history of paranoid schizophrenia and is currently taking olanzapine. What is the probable reason for her symptoms?
Your Answer: Acute dystonic reaction
Explanation:Antipsychotics have the potential to cause acute dystonic reactions, including oculogyric crises. Symptoms may also include jaw spasms and tongue protrusion. Treatment typically involves administering IV procyclidine and discontinuing the medication responsible for the reaction. Akathisia is another potential side effect, characterized by restlessness and an inability to sit still. Tardive dyskinesia is a long-term side effect that can develop after years of antipsychotic use, resulting in involuntary facial movements such as grimacing, tongue protrusion, and lip smacking. Parkinsonism is a term used to describe antipsychotic side effects that mimic Parkinson’s disease, such as bradykinesia, cogwheel rigidity, and a shuffling gait.
Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics. The latter were developed to address the extrapyramidal side-effects associated with the first generation of typical antipsychotics. Typical antipsychotics work by blocking dopaminergic transmission in the mesolimbic pathways through dopamine D2 receptor antagonism. They are associated with extrapyramidal side-effects and hyperprolactinaemia, which are less common with atypical antipsychotics.
Extrapyramidal side-effects (EPSEs) are common with typical antipsychotics and include Parkinsonism, acute dystonia, sustained muscle contraction, akathisia, and tardive dyskinesia. The latter is a late onset of choreoathetoid movements that may be irreversible and occur in 40% of patients. The Medicines and Healthcare products Regulatory Agency has issued specific warnings when antipsychotics are used in elderly patients, including an increased risk of stroke and venous thromboembolism. Other side-effects include antimuscarinic effects, sedation, weight gain, raised prolactin, impaired glucose tolerance, neuroleptic malignant syndrome, reduced seizure threshold, and prolonged QT interval.

Question 9

A 45-year-old man arrives at the hospital accompanied by his spouse. He appears restless, agitated, sweaty, and tremulous. According to his wife, the patient has been consuming at least half a bottle of vodka daily for several months. However, he has significantly reduced his alcohol intake in the past few days due to a lack of funds. His last drink was approximately eight hours ago. What medication would be the best option for treating this man's symptoms?
Your Answer: Lorazepam
Correct Answer: Chlordiazepoxide
Explanation:In the management of alcohol withdrawal, decreasing doses of long-acting benzodiazepines are commonly used. This is because long-term alcohol use can cause an imbalance in the brain’s excitatory and inhibitory neurotransmitters, leading to symptoms of an overactive sympathetic nervous system when alcohol is suddenly stopped. These symptoms can include restlessness, sweating, tremors, and agitation, and can even progress to seizures and delirium tremens. Long-acting benzodiazepines, such as chlordiazepoxide or diazepam, potentiate the action of the inhibitory neurotransmitter GABA and can help mitigate the risk of seizures and other withdrawal symptoms. Carbamazepine, an anticonvulsant, may also be used as a second-line medication if benzodiazepines are not appropriate. Haloperidol, a typical antipsychotic, is not typically used in alcohol withdrawal as it does not reduce the risk of seizures. Lorazepam, a short-acting benzodiazepine, is also not typically used in this context as long-acting benzodiazepines are preferred for their longer half-life.
Alcohol withdrawal occurs when an individual who has been consuming alcohol chronically suddenly stops or reduces their intake. Chronic alcohol consumption enhances the inhibitory effects of GABA in the central nervous system, similar to benzodiazepines, and inhibits NMDA-type glutamate receptors. However, alcohol withdrawal leads to the opposite effect, resulting in decreased inhibitory GABA and increased NMDA glutamate transmission. Symptoms of alcohol withdrawal typically start at 6-12 hours and include tremors, sweating, tachycardia, and anxiety. Seizures are most likely to occur at 36 hours, while delirium tremens, which includes coarse tremors, confusion, delusions, auditory and visual hallucinations, fever, and tachycardia, peak at 48-72 hours.
Patients with a history of complex withdrawals from alcohol, such as delirium tremens, seizures, or blackouts, should be admitted to the hospital for monitoring until their withdrawals stabilize. The first-line treatment for alcohol withdrawal is long-acting benzodiazepines, such as chlordiazepoxide or diazepam, which are typically given as part of a reducing dose protocol. Lorazepam may be preferable in patients with hepatic failure. Carbamazepine is also effective in treating alcohol withdrawal, while phenytoin is said to be less effective in treating alcohol withdrawal seizures.

A 65-year-old man with chronic schizophrenia complains of nausea and vomiting. He is given metoclopramide to alleviate his symptoms. However, after twenty minutes, he becomes restless and experiences severe oculogyric crises and oromandibular dystonia. What medication should be prescribed in this situation?
Your Answer: Procyclidine
Explanation:Procyclidine is the usual treatment for acute dystonia caused by antipsychotics. This patient’s acute dystonic reaction can be reversed with procyclidine, which is an anticholinergic medication that blocks acetylcholine. This medication can alleviate muscle stiffness, sweating, and excessive saliva production, and can also improve walking ability in individuals with Parkinson’s disease. The patient most likely developed this reaction due to long-term use of antipsychotics and subsequent administration of metoclopramide. While midazolam and lorazepam can relieve anxiety, they are not effective in treating dystonia.
Antipsychotics are a group of drugs used to treat schizophrenia, psychosis, mania, and agitation. They are divided into two categories: typical and atypical antipsychotics.
