Answer 42

"Factors associated with poor prognosis - Strong family history - Gradual onset - Low IQ - Premorbid history of social withdrawal - Lack of obvious precipitant - Early intervention services - MDT - Health promotion - Increased compliance with medication Medical: usually risperidone or olanzapine 1. Agree choice of antipsychotic 2. Titrate as necessary to minimum effective dose 3. Assess over 6-8 weeks 4. If not suitable, change drug and repeat steps 1-3 5. If not suitable use clozapine"

Answer 43

First rank symptoms: - Lack of insight - Auditory hallucinations: thought echo, 3rd person commentary - Thought disorder (insertion, withdrawal, interruption, broadcasting) - Delusional perceptions (abnormal significance for normal event) - External control of emotions - Somatic passivity: thoughts, sensations and actions are under external control

Negative symptoms: - Underactivity - Low motivation - Social withdrawal - Emotional flattening - Self-neglect

Answer 45

Multifactorial: genetic, environmental and social - Greatest risk factor is FHx (40% in monozygotic twins) - NRG1 has some part - Dopamine in mesolimbic system plays a key role - Excessive dopamine adds salience to mundane and insignificant thoughts or perceptions - Amphetamine misuse increases synaptic dopamine and can cause delusions and hallucinations

Answer 70

Physical symptoms not explained by organic disease and there is positive evidence or assumption that the symptoms are linked to psychological factors - Not a diagnosis of exclusion - requires positive psychological factors - Most are transient and not deliberately produced

Answer 71

Wernicke-Korsakoff syndrome (WKS) is a type of brain disorder caused by a lack of vitamin B1 (thiamine). The syndrome is actually two separate conditions that can occur at the same time, Wernicke’s disease (WD) and Korsakoff syndrome. Usually, people get the symptoms of WD first.

Smoking cessation can cause a significant rise in clozapine levels, and so it should be discussed with a psychiatrist before stopping smoking. Starting smoking, or smoking more, can reduce clozapine levels. Stopping drinking can also reduce levels, as alcohol binges can increase the level. Omitting doses will cause a reduction in clozapine levels, and stress and weight gain won't have major effects on the level

Answer 248

Flashbacks are an immersive experience, so would not be an accurate description of this scenario. Perseveration is a sign which may be associated with Parkinson's Disease. It refers to a patient needlessly repeating a word or phrase which they had previously expressed. Anergia is not a speech abnormality. It describes a lack of energy- or increased fatigability with minimal exertion. This may be a symptom of unipolar depression. Flight of Ideas is a phenomenon which may be seen during a manic phase. It is a rapid shifting of ideas with only superficial associations between them, such that the speech is difficult to follow. Circumstantiality is the correct answer. This refers to overinclusive speech that is delayed in reaching its final goal. It can be a sign of anxiety or hypomania. It is still possible to follow the speech, and it does eventually reach its goal.

Answer 249

Having a personality disorder is a predisposing factor for brief psychotic disorder. It does often result in a return to baseline functioning.

Patients are not always aware of the change in their behaviour.

Answer 251

1. Mirtazapine is an antidepressant preferred in patients with anorexia nervosa as it also elevates the appetite and produces weight gain. 2. Fluoxetine is a selective serotonin reuptake inhibitor and it is not contraindicated in anorexia nervosa. It can produce gastrointestinal distress or sexual dysfunction as side-effects, and young patients can therefore not be compliant with the medication. 3. Amitriptyline is a tricyclic antidepressant and is used mostly for major depression. It has a worse side-effect profile than selective serotonin reuptake inhibitors. 4. Bupropion is an atypical antidepressant which is commonly used for smoking cessation. It is however contraindicated in anorexia nervosa or bulimia nervosa as it lowers the seizure threshold and predisposed these patients to seizures. 5. Milnacipran is a serotonin-norepinephrine reuptake inhibitor and it is not contraindicated in anorexia nervosa. It has stimulant properties and the most common side effect is an increase in blood pressure.
