Which statement is incorrect about the evidence supporting the management of schizophrenia?
Your Answer: Transcranial magnetic stimulation (TMS) has been shown be effective
Correct Answer: Evidence supports better outcomes with high-dose antipsychotic therapy
Explanation:The available evidence regarding high-dose antipsychotic therapy is mixed and generally unfavorable.
Schizophrenia Treatment
When it comes to treating schizophrenia, there are several consistent findings that have been discovered. One of these is that clozapine is more effective than other antipsychotics for neuroleptic-refractory positive symptoms. Additionally, transcranial magnetic stimulation (TMS) has been found to be effective, while cognitive behavioural therapy can reduce psychotic symptoms. Family and patient psychoeducation can also reduce relapses, and social skills training has been shown to improve outcomes. Finally, early intervention during the first episode of psychosis has been found to improve outcomes as well.

Which of the following is not considered a risk factor for recurrence in unipolar depression?
Your Answer: Male gender
Explanation:Factors that Increase the Risk of Recurrent Depression
Depression is a disorder that often recurs. Research shows that 50-85% of individuals who experience a single episode of depression will have a second episode, and of those, 80-90% will have a third episode (Forshall, 1999). Due to the high likelihood of recurrence, NICE recommends that individuals who have had two of more episodes of depression in the recent past should continue taking antidepressants for at least two years.
Several factors increase the risk of recurrent depression, including a family history of depression, recurrent dysthymia, concurrent non-affective psychiatric illness, female gender, long episode duration, chronic medical illness, and lack of a confiding relationship. It is important for individuals with a history of depression to be aware of these risk factors and to work with their healthcare provider to develop a plan for preventing future episodes.

What is the risk factor that the selection drift hypothesis aims to explain in relation to schizophrenia?
Your Answer: Social class
Explanation:Schizophrenia: Understanding the Risk Factors
Social class is a significant risk factor for schizophrenia, with people of lower socioeconomic status being more likely to develop the condition. Two hypotheses attempt to explain this relationship, one suggesting that environmental exposures common in lower social class conditions are responsible, while the other suggests that people with schizophrenia tend to drift towards the lower class due to their inability to compete for good jobs.
While early studies suggested that schizophrenia was more common in black populations than in white, the current consensus is that there are no differences in rates of schizophrenia by race. However, there is evidence that rates are higher in migrant populations and ethnic minorities.
Gender and age do not appear to be consistent risk factors for schizophrenia, with conflicting evidence on whether males of females are more likely to develop the condition. Marital status may also play a role, with females with schizophrenia being more likely to marry than males.
Family history is a strong risk factor for schizophrenia, with the risk increasing significantly for close relatives of people with the condition. Season of birth and urban versus rural place of birth have also been shown to impact the risk of developing schizophrenia.
Obstetric complications, particularly prenatal nutritional deprivation, brain injury, and influenza, have been identified as significant risk factors for schizophrenia. Understanding these risk factors can help identify individuals who may be at higher risk for developing the condition and inform preventative measures.

In the management of acute mania in adult patients, NICE recommends which of the following?
Your Answer: Risperidone
Explanation:Bipolar Disorder: Diagnosis and Management
Bipolar disorder is a lifelong condition characterized by episodes of mania or hypomania and episodes of depressed mood. The peak age of onset is 15-19 years, and the lifetime prevalence of bipolar I disorders is estimated to be around 2.1%. The diagnosis of bipolar disorder is based on the presence of manic or hypomanic episodes, which are characterized by elevated of expansive mood, rapid speech, and increased activity of energy. Psychotic symptoms, such as delusions and hallucinations, may also be present.
Bipolar depression differs from unipolar depression in several ways, including more rapid onset, more frequent episodes, and shorter duration. Rapid cycling is a qualifier that can be applied to bipolar I of bipolar II disorder and is defined as the presence of at least four mood episodes in the previous 12 months that meet the criteria for a manic, hypomanic, of major depressive episode.
The management of bipolar disorder involves acute and long-term interventions. Acute management of mania or hypomania may involve stopping antidepressants and offering antipsychotics of mood stabilizers. Long-term management may involve psychological interventions and pharmacological treatments such as lithium, valproate, of olanzapine.
It is important to note that valproate should not be offered to women of girls of childbearing potential for long-term bipolar disorder unless other options are ineffective of not tolerated and a pregnancy prevention program is in place. Aripiprazole is recommended as an option for treating moderate to severe manic episodes in adolescents with bipolar I disorder.
Overall, the diagnosis and management of bipolar disorder require a comprehensive approach that takes into account the individual’s symptoms, history, and preferences.

What is a known cause of Stevens-Johnson Syndrome?
Your Answer: Carbamazepine
Explanation:Stevens-Johnson syndrome is a rare but serious condition that affects the skin and mucous membranes. It is often caused by a reaction to medication of infection and can start with flu-like symptoms. The condition is characterized by a painful rash that spreads and blisters, leading to the shedding of the top layer of affected skin. Hospitalization is usually required as it is a medical emergency. Medications that have been known to cause Stevens-Johnson syndrome include lamotrigine, phenobarbital, sertraline, and certain types of NSAIDs such as meloxicam, piroxicam, and tenoxicam.
Antiepileptic drugs (AEDs) are commonly used for the treatment of epilepsy, but many of them also have mood stabilizing properties and are used for the prophylaxis and treatment of bipolar disorder. However, some AEDs carry product warnings for serious side effects such as hepatic failure, pancreatitis, thrombocytopenia, and skin reactions. Additionally, some AEDs have been associated with an increased risk of suicidal behavior and ideation.
Behavioral side-effects associated with AEDs include depression, aberrant behaviors, and the development of worsening of irritability, impulsivity, anger, hostility, and aggression. Aggression can occur before, after, of in between seizures. Some AEDs are considered to carry a higher risk of aggression, including levetiracetam, perampanel, and topiramate. However, data on the specific risk of aggression for other AEDs is lacking of mixed. It is important for healthcare providers to carefully consider the potential risks and benefits of AEDs when prescribing them for patients with epilepsy of bipolar disorder.

A patient with chronic depression presents with unusual somatic symptoms after trying a medication called hypericum perforatum that she purchased in Germany. Which of the following symptoms could be attributed to the new medication?
Your Answer: Hiccups
Correct Answer: Headache
Explanation:St John’s Wort may cause several side effects, including dry mouth, nausea, rash, diarrhea, fatigue, dizziness, headache, and restlessness.
Herbal Remedies for Depression and Anxiety
Depression can be treated with Hypericum perforatum (St John’s Wort), which has been found to be more effective than placebo and as effective as standard antidepressants. However, its use is not advised due to uncertainty about appropriate doses, variation in preparations, and potential interactions with other drugs. St John’s Wort can cause serotonin syndrome and decrease levels of drugs such as warfarin and ciclosporin. The effectiveness of the combined oral contraceptive pill may also be reduced.
Anxiety can be reduced with Piper methysticum (kava), but it cannot be recommended for clinical use due to its association with hepatotoxicity.

What is the combination of antidepressants that should not be used together?
Your Answer: Paroxetine and Moclobemide
Correct Answer: Phenelzine and sertraline
Explanation:The Dangers of Combining Antidepressants: A Review of the Evidence
Antidepressants are commonly prescribed to treat depression and other mental health conditions. However, the combination of certain antidepressants can be dangerous and even fatal. In particular, the combination of irreversible MAOIs such as phenelzine and tranylcypromine with SSRIs can lead to a high risk of serotonin syndrome.
Serotonin syndrome is a potentially life-threatening condition that occurs when there is an excess of serotonin in the body. Symptoms can include agitation, confusion, rapid heart rate, high blood pressure, muscle rigidity, and seizures. Fatalities have been reported in cases where patients have combined these two types of antidepressants.
It is important for healthcare providers to be aware of the risks associated with combining antidepressants and to carefully monitor patients who are taking multiple medications. Patients should also be informed of the potential dangers and advised to seek medical attention immediately if they experience any symptoms of serotonin syndrome. By taking these precautions, we can help ensure the safe and effective use of antidepressants in the treatment of mental health conditions.

What factor increases the likelihood of non-fatal repetition of self-harm?
Your Answer: Alcohol dependency
Explanation:Self-Harm and its Management
Self-harm refers to intentional acts of self-poisoning of self-injury. It is prevalent among younger people, with an estimated 10% of girls and 3% of boys aged 15-16 years having self-harmed in the previous year. Risk factors for non-fatal repetition of self-harm include previous self-harm, personality disorder, hopelessness, history of psychiatric treatment, schizophrenia, alcohol abuse/dependence, and drug abuse/dependence. Suicide following an act of self-harm is more likely in those with previous episodes of self-harm, suicidal intent, poor physical health, and male gender.
Risk assessment tools are not recommended for predicting future suicide of repetition of self-harm. The recommended interventions for self-harm include 4-10 sessions of CBT specifically structured for people who self-harm and considering DBT for adolescents with significant emotional dysregulation. Drug treatment as a specific intervention to reduce self-harm should not be offered.
In the management of ingestion, activated charcoal can help if used early, while emetics and cathartics should not be used. Gastric lavage should generally not be used unless recommended by TOXBASE. Paracetamol is involved in 30-40% of acute presentations with poisoning. Intravenous acetylcysteine is the treatment of choice, and pseudo-allergic reactions are relatively common. Naloxone is used as an antidote for opioid overdose, while flumazenil can help reduce the need for admission to intensive care in benzodiazepine overdose.
For superficial uncomplicated skin lacerations of 5 cm of less in length, tissue adhesive of skin closure strips could be used as a first-line treatment option. All children who self-harm should be admitted for an overnight stay at a pediatric ward.

What is another name for asthenic personality disorder?
Your Answer: Histrionic personality disorder
Correct Answer: Dependent personality disorder
Explanation:Asthenic personality disorder, which used to be a common term, is now referred to as dependent personality disorder. It is important to be aware of this older term as it may still appear in older records.
Dependent Personality Disorder is a type of personality disorder where individuals excessively rely on others for support and fear abandonment. This disorder falls under Cluster C personality disorders. The DSM-5 criteria for this disorder includes exhibiting five of more of the following behaviors: difficulty making decisions without input from others, requiring others to take on responsibilities, fear of disagreement, difficulty starting projects without support, excessive need for nurturance and support, feeling vulnerable and helpless when alone, seeking new relationships when one ends, and having an unrealistic fear of being left alone and unable to care for oneself. The ICD-11 removed the specific diagnosis of Dependent Personality Disorder, but individuals can still be diagnosed with a general personality disorder if they exhibit dependent features.

Which statement about multiple sclerosis is incorrect?
Your Answer: It often presents with diverse clinical signs
Correct Answer: It is more common in males
Explanation:Psychiatric Consequences of Multiple Sclerosis
Multiple sclerosis (MS) is a neurological disorder that affects individuals between the ages of 20 and 40. It is characterized by multiple demyelinating lesions in the optic nerves, cerebellum, brainstem, and spinal cord. MS presents with diverse neurological signs, including optic neuritis, internuclear ophthalmoplegia, and ocular motor cranial neuropathy.
Depression is the most common psychiatric condition seen in MS, with a lifetime prevalence of 25-50%. The symptoms of depression in people with MS tend to be different from those without MS. The preferred diagnostic indicators for depression in MS include pervasive mood change, diurnal mood variation, suicidal ideation, functional change not related to physical disability, and pessimistic of negative patterns of thinking. Selective serotonin reuptake inhibitors (SSRIs) are considered first-line treatment for depression in patients with MS.
Suicide is common in MS, with recognized risk factors including male gender, young age at onset of illness, current of previous history of depression, social isolation, and substance misuse. Mania is more common in people with MS, and mood stabilizers are recommended for treatment. Pathological laughing and crying, defined as uncontrollable laughing and/of crying without the associated affect, occurs in approximately 10% of cases of MS. Emotional lability, defined as an excessive emotional response to a minor stimulus, is also common in MS and can be treated with amitriptyline and SSRIs.
The majority of cases of neuropsychiatric side effects from corticosteroids fit an affective profile of mania and/of depression. Psychotic symptoms, particularly hallucinations, are present in up to half of these cases. Glatiramer acetate has not been associated with neuropsychiatric side-effects. The data regarding the risk of mood symptoms related to interferon use is conflicting.
In conclusion, MS has significant psychiatric consequences, including depression, suicide, mania, pathological laughing and crying, emotional lability, and neuropsychiatric side effects from treatment. Early recognition and treatment of these psychiatric symptoms are essential for improving the quality of life of individuals with MS.

A child presents with paracetamol poisoning after accidentally ingesting a large amount. Blood tests show the need for treatment with N-acetylcysteine. IV N-acetylcysteine treatment is started, but the child experiences an anaphylactoid reaction characterized by a skin rash, itching, nausea, mild hypotension, and flushing.
What would be the most suitable course of action in this scenario?Your Answer: Continue the IV acetylcysteine at the same rate whilst also administering an antihistamine
Correct Answer: Suspend the IV acetylcysteine, apply supportive treatment and restart at a lower dose
Explanation:Paracetamol overdose can cause liver damage due to the production of a reactive metabolite called N-acetyl-p-benzoquinoneimine (NAPQI) by cytochrome P450 enzymes. Glutathione detoxifies NAPQI at therapeutic doses, but overdose depletes glutathione. Antidotes such as acetylcysteine and methionine provide a substrate for glutathione synthesis, reducing hepatotoxicity. IV acetylcysteine is the preferred option and more effective than oral acetylcysteine and methionine. Adverse reactions to IV acetylcysteine are rare but can include urticaria, pruritus, facial flushing, wheezing, dyspnoea, and hypotension. These reactions are not true anaphylaxis and do not require prior exposure to N-acetylcysteine. Patients should be observed for signs of anaphylactoid reactions, and management is supportive with temporary halting of slowing of the infusion and administration of antihistamines. Patients with a history of atopy and asthma may be at increased risk of developing an anaphylactoid reaction. (Benlamkadem, 2018).
Self-Harm and its Management
Self-harm refers to intentional acts of self-poisoning of self-injury. It is prevalent among younger people, with an estimated 10% of girls and 3% of boys aged 15-16 years having self-harmed in the previous year.

How is a brief episode of psychotic symptoms lasting less than three months referred to in the ICD-11?
Your Answer: Acute and transient psychotic disorder
Explanation:The ICD-11 categorizes brief psychotic episodes that occur suddenly without warning as acute and transient psychotic disorder, lasting for less than three months but typically less than one month. Meanwhile, the DSM-5 distinguishes between two similar conditions: brief psychotic disorder, which resolves within a month, and schizophreniform disorder, which persists for more than one month but less than six months.
– Schizophrenia and other primary psychotic disorders are characterized by impairments in reality testing and alterations in behavior.
– Schizophrenia is a chronic mental health disorder with symptoms including delusions, hallucinations, disorganized speech of behavior, and impaired cognitive ability.
– The essential features of schizophrenia include persistent delusions, persistent hallucinations, disorganized thinking, experiences of influence, passivity of control, negative symptoms, grossly disorganized behavior, and psychomotor disturbances.
– Schizoaffective disorder is diagnosed when all diagnostic requirements for schizophrenia are met concurrently with mood symptoms that meet the diagnostic requirements of a moderate or severe depressive episode, a manic episode, of a mixed episode.
– Schizotypal disorder is an enduring pattern of unusual speech, perceptions, beliefs, and behaviors that are not of sufficient intensity of duration to meet the diagnostic requirements of schizophrenia, schizoaffective disorder, of delusional disorder.
– Acute and transient psychotic disorder is characterized by an acute onset of psychotic symptoms, which can include delusions, hallucinations, disorganized thinking, of experiences of influence, passivity of control, that emerge without a prodrome, progressing from a non-psychotic state to a clearly psychotic state within 2 weeks.
– Delusional disorder is diagnosed when there is a presence of a delusion of set of related delusions, typically persisting for at least 3 months and often much longer, in the absence of a depressive, manic, of mixed episode. -

A woman with bipolar disorder presents as manic. She is taking lithium and you request levels which come back as 1.1 mmol/L. Which of the following should you do?:
Your Answer: Stop lithium and start quetiapine
Correct Answer: Add in olanzapine
Explanation:Achieving a level of 1.1 mmol/L indicates that the appropriate therapeutic level of lithium has been reached, and any further increase in dosage would be unsafe (as per the Maudsley 14th guidelines, which recommend a level between 1.0-1.2). To address this, the guidelines suggest adding an antipsychotic medication, preferably one that is licensed for bipolar disorder, such as olanzapine, risperidone, quetiapine, of aripiprazole.

At the beginning of the CATIE study, what was the proportion of patients diagnosed with metabolic syndrome?
Your Answer: 20%
Correct Answer: 40%
Explanation:The information provided is valuable because the CATIE study was conducted in a real-world setting, making the estimate potentially applicable to the UK.
CATIE Study: Comparing Antipsychotic Medications for Schizophrenia Treatment
The Clinical Antipsychotic Trials of Intervention Effectiveness (CATIE) Study, funded by the National Institute of Mental Health (NIMH), was a nationwide clinical trial that aimed to compare the effectiveness of older and newer antipsychotic medications used to treat schizophrenia. It is the largest, longest, and most comprehensive independent trial ever conducted to examine existing therapies for schizophrenia. The study consisted of two phases.
Phase I of CATIE compared four newer antipsychotic medications to one another and an older medication. Participants were followed for 18 months to evaluate longer-term patient outcomes. The study involved over 1400 participants and was conducted at various treatment sites, representative of real-life settings where patients receive care. The results from CATIE are applicable to a wide range of people with schizophrenia in the United States.
The medications were comparably effective, but high rates of discontinuation were observed due to intolerable side-effects of failure to adequately control symptoms. Olanzapine was slightly better than the other drugs but was associated with significant weight gain as a side-effect. Surprisingly, the older, less expensive medication (perphenazine) used in the study generally performed as well as the four newer medications. Movement side effects primarily associated with the older medications were not seen more frequently with perphenazine than with the newer drugs.
Phase II of CATIE sought to provide guidance on which antipsychotic to try next if the first failed due to ineffectiveness of intolerability. Participants who discontinued their first antipsychotic medication because of inadequate management of symptoms were encouraged to enter the efficacy (clozapine) pathway, while those who discontinued their first treatment because of intolerable side effects were encouraged to enter the tolerability (ziprasidone) pathway. Clozapine was remarkably effective and was substantially better than all the other atypical medications.
The CATIE study also looked at the risk of metabolic syndrome (MS) using the US National Cholesterol Education Program Adult Treatment Panel criteria. The prevalence of MS at baseline in the CATIE group was 40.9%, with female patients being three times as likely to have MS compared to matched controls and male patients being twice as likely.

A woman in her 50s who has a lengthy history of schizophrenia has experimented with various antipsychotics before and is now interested in trying a new one. She cannot remember the names of the ones she has taken in the past but remembers being informed that she experienced anticholinergic side-effects and wants to avoid them at all costs. Which of the following choices is most probable to lead to anticholinergic side-effects?
Your Answer: Olanzapine
Correct Answer: Clozapine
Explanation:Clozapine exhibits significant anticholinergic effects, resulting in both xerostomia and excessive salivation.
Antipsychotics: Common Side Effects and Relative Adverse Effects
Antipsychotics are medications used to treat various mental health conditions, including schizophrenia and bipolar disorder. However, they can also cause side effects that can be bothersome of even serious. The most common side effects of antipsychotics are listed in the table below, which includes the adverse effects associated with their receptor activity.
Antidopaminergic effects: These effects are related to the medication’s ability to block dopamine receptors in the brain. They can cause galactorrhoea, gynecomastia, menstrual disturbance, lowered sperm count, reduced libido, Parkinsonism, dystonia, akathisia, and tardive dyskinesia.
Anticholinergic effects: These effects are related to the medication’s ability to block acetylcholine receptors in the brain. They can cause dry mouth, blurred vision, urinary retention, and constipation.
Antiadrenergic effects: These effects are related to the medication’s ability to block adrenaline receptors in the body. They can cause postural hypotension and ejaculatory failure.
Histaminergic effects: These effects are related to the medication’s ability to block histamine receptors in the brain. They can cause drowsiness.
The Maudsley Guidelines provide a rough guide to the relative adverse effects of different antipsychotics. The table below summarizes their findings, with +++ indicating a high incidence of adverse effects, ++ indicating a moderate incidence, + indicating a low incidence, and – indicating a very low incidence.

You are asked to evaluate a 35 year-old man on the medical ward with HIV. He has just recuperated from an episode of mania and has a history of bipolar disorder. You observe that he recently visited the HIV specialist in clinic and had an eGFR of 45. What would be the most suitable medication for the extended management of this man's bipolar disorder?
Your Answer: Lamotrigine
Correct Answer: Valproate
Explanation:The individual has bipolar disorder and needs ongoing treatment. The recommended initial medications are Lithium and Valproate. However, due to the person’s eGFR of 45, which indicates stage 3a CKD, Lithium is not a viable option. It is important to note that an eGFR < 90 in a working age adult is a strong indication of renal impairment, although a detailed understanding of CKD is not necessary for the MRCPsych exams. Therefore, Valproate is the preferred treatment in this case. HIV and Mental Health: Understanding the Relationship and Treatment Options Human immunodeficiency virus (HIV) is a blood-borne virus that causes cellular immune deficiency, resulting in a decrease in the number of CD4+ T-cells. People with severe mental illness are at increased risk of contracting and transmitting HIV, and the prevalence of HIV infection among them is higher than in the general population. Antiretroviral drugs are used to manage HIV, but they are not curative. Depression is the most common mental disorder in the HIV population, and it can result from HIV of the psycho-social consequences of having the condition. HIV-associated neurocognitive disorder (HAND) is the umbrella term for the spectrum of neurocognitive impairment induced by HIV, ranging from mild impairment through to dementia. Poor episodic memory is the most frequently reported cognitive difficulty in HIV-positive individuals. Treatment options for mental health issues in people with HIV include atypical antipsychotics for psychosis, SSRIs for depression and anxiety, valproate for bipolar disorder, and antiretroviral therapy for HAND. It is important to avoid benzodiazepines for delirium and MAOIs for depression. Understanding the relationship between HIV and mental health and providing appropriate treatment options can improve the quality of life for people living with HIV.

Which symptom is not commonly linked to PTSD?
Your Answer: Hallucinations
Explanation:Common signs of PTSD may include:
Stress disorders, such as Post Traumatic Stress Disorder (PTSD), are emotional reactions to traumatic events. The diagnosis of PTSD requires exposure to an extremely threatening of horrific event, followed by the development of a characteristic syndrome lasting for at least several weeks, consisting of re-experiencing the traumatic event, deliberate avoidance of reminders likely to produce re-experiencing, and persistent perceptions of heightened current threat. Additional clinical features may include general dysphoria, dissociative symptoms, somatic complaints, suicidal ideation and behaviour, social withdrawal, excessive alcohol of drug use, anxiety symptoms, and obsessions of compulsions. The emotional experience of individuals with PTSD commonly includes anger, shame, sadness, humiliation, of guilt. The onset of PTSD symptoms can occur at any time during the lifespan following exposure to a traumatic event, and the symptoms and course of PTSD can vary significantly over time and individuals. Key differentials include acute stress reaction, adjustment disorder, and complex PTSD. Management of PTSD includes trauma-focused cognitive behavioral therapy (CBT), eye movement desensitization and reprocessing (EMDR), and supported trauma-focused computerized CBT interventions. Drug treatments, including benzodiazepines, are not recommended for the prevention of treatment of PTSD in adults, but venlafaxine of a selective serotonin reuptake inhibitor (SSRI) may be considered for adults with a diagnosis of PTSD if the person has a preference for drug treatment. Antipsychotics such as risperidone may be considered in addition if disabling symptoms and behaviors are present and have not responded to other treatments. Psychological debriefing is not recommended for the prevention of treatment of PTSD. For children and young people, individual trauma-focused CBT interventions of EMDR may be considered, but drug treatments are not recommended.

Explanation:Psychomotor activation, also known as psychomotor agitation, is characterized by increased speed of thinking, difficulty focusing, excessive energy, and a sense of restlessness. These terms can be used interchangeably.
Bipolar Disorder Versus BPD
Bipolar disorder and borderline personality disorder (BPD) can be distinguished from each other based on several factors. Bipolar disorder is characterized by psychomotor activation, which is not typically seen in BPD. Additionally, self-destructive cutting behavior is rare in bipolar disorder but common in BPD. BPD is often associated with sexual trauma, while bipolar disorder has a lower prevalence of sexual trauma. Other BPD features such as identity disturbance and dissociative symptoms are not typically seen in bipolar disorder. Finally, bipolar disorder is highly heritable, while BPD has a lower genetic loading. Understanding these differences is important for accurate diagnosis and treatment.

Which drug interacts with a G-coupled receptor to exert its effects?
Your Answer: Cannabis
Explanation:Mechanisms of action for illicit drugs can be classified based on their effects on ionotropic receptors of ion channels, G coupled receptors, of monoamine transporters. Cocaine and amphetamine both increase dopamine levels in the synaptic cleft, but through different mechanisms. Cocaine directly blocks the dopamine transporter, while amphetamine binds to the transporter and increases dopamine efflux through various mechanisms, including inhibition of vesicular monoamine transporter 2 and monoamine oxidase, and stimulation of the intracellular receptor TAAR1. These mechanisms result in increased dopamine levels in the synaptic cleft and reuptake inhibition.

What is the most probable diagnosis for a mother who experiences feelings of sadness and tearfulness two days after giving birth to her second child, despite having no prior history of mental health issues?
Your Answer: Baby blues
Explanation:Psychiatric Issues in the Postpartum Period
The period following childbirth, known as the postpartum period, can be a time of significant psychiatric challenges for women. Many women experience a temporary mood disturbance called baby blues, which is characterized by emotional instability, sadness, and tearfulness. This condition typically resolves within two weeks.
However, a minority of women (10-15%) experience postpartum depression, which is similar to major depression in its clinical presentation. In contrast, a very small number of women (1-2 per 1000) experience postpartum psychosis, also known as puerperal psychosis. This is a severe form of psychosis that occurs in the weeks following childbirth.
Research suggests that there may be a link between puerperal psychosis and mood disorders, as approximately 50% of women who develop the condition have a family history of mood disorder. Puerperal psychosis typically begins within the first two weeks following delivery. It is important for healthcare providers to be aware of these potential psychiatric issues and to provide appropriate support and treatment to women during the postpartum period.

A stable postpartum patient, with a history of depression, has just given birth. She asks for your advice about breastfeeding. She has been stable on her current antidepressant medication for several years, although had multiple episodes of depression in the past.
Which of the following prescribed medications would lead you to advise against breastfeeding?Your Answer: Aripiprazole
Correct Answer: Clozapine
Explanation:In the scenario described, the patient has treatment-resistant schizophrenia and is currently stable. Therefore, it may not be necessary to change their antipsychotic medication, as the benefits of continuing their current medication may outweigh the potential risks to the baby if they choose to breastfeed. However, it is important to consider the specific medication being taken and consult with a healthcare professional to determine the best course of action.

Which of the following is not a common cardiac finding in a patient with anorexia nervosa?
Your Answer: Shortened QT interval
Explanation:Anorexia is a serious mental health condition that can have severe physical complications. These complications can affect various systems in the body, including the cardiac, skeletal, hematologic, reproductive, metabolic, gastrointestinal, CNS, and dermatological systems. Some of the recognized physical complications of anorexia nervosa include bradycardia, hypotension, osteoporosis, anemia, amenorrhea, hypothyroidism, delayed gastric emptying, cerebral atrophy, and lanugo.
The Royal College of Psychiatrists has issued advice on managing sick patients with anorexia nervosa, recommending hospital admission for those with high-risk items. These items include a BMI of less than 13, a pulse rate of less than 40 bpm, a SUSS test score of less than 2, a sodium level of less than 130 mmol/L, a potassium level of less than 3 mmol/L, a serum glucose level of less than 3 mmol/L, and a QTc interval of more than 450 ms. The SUSS test involves assessing the patient’s ability to sit up and squat without using their hands. A rating of 0 indicates complete inability to rise, while a rating of 3 indicates the ability to rise without difficulty. Proper management and treatment of anorexia nervosa are crucial to prevent of manage these physical complications.

What is the relationship between suicide and deliberate self-harm (DSH)?
Your Answer: High suicide intent is not associated with greater risk of suicide, in the first year following DSH
Correct Answer: DSH is the strongest risk factor for suicide
Explanation:Patients who have a history of repeated DSH are at a significantly higher risk for suicide. While high suicidal intent is associated with greater risk of suicide, it is not a reliable predictor for individual patients, particularly in the first year following DSH. DSH remains the strongest risk factor for suicide.
Suicide Rates Following Self-Harm
Most individuals who engage in self-harm do not go on to commit suicide, which makes risk assessment challenging. A study conducted in the UK in 2015 by Hawton found that 0.5% of individuals died by suicide in the first year following self-harm, with a higher rate among males (0.82%) than females (0.27%). Over the two-year period following self-harm, 1.6% died by suicide, with more occurrences in the second year. Interestingly, a study by Murphy in 2012 found that the rate of suicide following self-harm was higher in the elderly (those over 60), with a rate of 1.5 suicides in the first 12 months. The only significant risk factor for suicide following self-harm in this study was the use of a violent method in the initial episode.

What characteristic is commonly observed in individuals with paranoid personality disorder?
Your Answer:
Correct Answer: Increased sensitivity to criticism and setbacks
Explanation:Paranoid Personality Disorder is a type of personality disorder where individuals have a deep-seated distrust and suspicion of others, often interpreting their actions as malevolent. This disorder is characterized by a pattern of negative interpretations of others’ words, actions, and intentions, leading to a reluctance to confide in others and holding grudges for long periods of time. The DSM-5 criteria for this disorder include at least four of the following symptoms: unfounded suspicions of exploitation, harm, of deception by others, preoccupation with doubts about the loyalty of trustworthiness of friends of associates, reluctance to confide in others due to fear of malicious use of information, reading negative meanings into benign remarks of events, persistent grudges, perceiving attacks on one’s character of reputation that are not apparent to others and reacting angrily of counterattacking, and recurrent suspicions of infidelity in a partner without justification. The ICD-11 does not have a specific category for paranoid personality disorder but covers many of its features under the negative affectivity qualifier under the element of mistrustfulness.
