1Which of the following clinical features is classified as a Schneiderian first-rank symptom of schizophrenia?
A.Visual hallucinations of unformed shadowy figures
B.Audible thoughts (Gedankenlautwerden)
C.Persecutory delusions regarding workplace colleagues
D.Affective blunting and avolition
Explanation: Audible thoughts (Gedankenlautwerden or thought echo), along with thought insertion, thought withdrawal, thought broadcasting, third-person auditory hallucinations, and somatic passivity, are classic Schneiderian first-rank symptoms. Although not pathognomonic according to modern diagnostic criteria, they carry historical and diagnostic significance in identifying psychotic phenomenology. Unformed visual hallucinations, non-passivity persecutory delusions, and negative symptoms are not first-rank symptoms.
2A 23-year-old man is brought in by his family. Over the past 4 months he has withdrawn from friends and stopped attending university, and for the last 5 weeks he has heard voices commenting on his actions and has shown disorganized speech. There is no mood episode, substance use or medical cause. What is the most appropriate DSM-5-TR diagnosis at this point?
A.Brief psychotic disorder
B.Schizophreniform disorder
C.Schizophrenia, first episode
D.Schizoaffective disorder
Explanation: DSM-5-TR schizophrenia requires at least 6 months of continuous signs of disturbance, including at least 1 month of active-phase symptoms. Schizophreniform disorder has the same symptom criteria but a total duration (prodromal, active and residual phases) of at least 1 month and less than 6 months; while the patient is still ill it is labeled 'provisional'. This patient's illness has lasted 4 months, with 5 weeks of active symptoms, so schizophreniform disorder is the correct current diagnosis. Brief psychotic disorder lasts at least 1 day but less than 1 month, with full return to baseline.
3A 28-year-old man with treatment-resistant schizophrenia is being evaluated for initiation of clozapine. What baseline absolute neutrophil count (ANC) is required before commencing clozapine therapy?
A.At least 1,500/mm³ (or at least 1,000/mm³ for benign ethnic neutropenia)
B.At least 2,500/mm³ regardless of ethnicity
C.At least 1,000/mm³ for all general populations
D.At least 3,500/mm³ with a total white blood cell count above 6,000/mm³
Explanation: Standard international clozapine monitoring guidelines require an absolute neutrophil count (ANC) of at least 1,500/mm³ in the general population prior to initiating clozapine. In individuals with confirmed benign ethnic neutropenia (BEN), a lower baseline ANC threshold of at least 1,000/mm³ is acceptable. Routine monitoring involves weekly blood counts for the first 18 weeks, followed by biweekly and then monthly testing to detect agranulocytosis.
4A 22-year-old man with a first episode of psychosis develops sudden, sustained upward deviation of the eyes and involuntary torticollis 24 hours after receiving intramuscular haloperidol. What is the most appropriate acute treatment?
A.Intramuscular flumazenil
B.Oral propranolol 20 mg
C.Intravenous dantrolene
D.IM benztropine
Explanation: The clinical presentation is an acute dystonic reaction (oculogyric crisis and spasmodic torticollis), which typically occurs within 24 to 72 hours of starting potent D2 receptor antagonist antipsychotics like haloperidol. The rapid and definitive treatment is administration of an anticholinergic agent, such as benztropine or procyclidine (or diphenhydramine) intramuscularly or intravenously. Symptoms usually resolve within 15 to 30 minutes following administration.
5What is the primary neurobiological mechanism thought to underlie the pathophysiology of tardive dyskinesia following prolonged exposure to first-generation antipsychotics?
A.Degeneration of cortical cholinergic interneurons
B.Striatal D2 receptor supersensitivity and upregulation
C.Serotonergic hyperstimulation in the raphe nuclei
D.Loss of GABAergic transmission in the locus coeruleus
Explanation: Tardive dyskinesia is primarily attributed to chronic blockade of dopamine D2 receptors in the nigrostriatal pathway, leading to compensatory D2 receptor supersensitivity and post-synaptic receptor upregulation. When this receptor upregulation persists, spontaneous involuntary choreoathetoid movements occur, especially involving the perioral and lingual muscles. Modern pharmacotherapy utilizes vesicular monoamine transporter 2 (VMAT2) inhibitors (e.g., valbenazine, deutetrabenazine) to reduce presynaptic dopamine release.
6A 26-year-old woman taking risperidone for schizophrenia develops galactorrhea, amenorrhea, and reduced bone mineral density. Antagonism of dopamine D2 receptors in which cerebral pathway is responsible for these endocrine effects?
A.Mesolimbic pathway
B.Mesocortical pathway
C.Tuberoinfundibular pathway
D.Nigrostriatal pathway
Explanation: Dopamine acts as the major prolactin-inhibiting factor (PIF) in the tuberoinfundibular pathway, which connects the arcuate nucleus of the hypothalamus to the anterior pituitary gland. Blockade of D2 receptors in this pathway by antipsychotics (especially risperidone, paliperidone, and typical neuroleptics) removes the tonic inhibitory control on lactotroph cells, resulting in hyperprolactinemia, galactorrhea, amenorrhea, and sexual dysfunction.
7A 41-year-old woman with schizophrenia remains floridly psychotic despite adherence-confirmed trials (with therapeutic plasma levels) of aripiprazole 30 mg/day for 8 weeks and then paliperidone palmitate long-acting injection for 4 months. Her absolute neutrophil count is 2,100/mm³. Which treatment has the strongest evidence for her condition?
A.Clozapine, with absolute neutrophil count monitoring
B.Switch to a third non-clozapine antipsychotic such as haloperidol
C.Combine two non-clozapine antipsychotics at full dose
D.Electroconvulsive therapy as monotherapy
Explanation: Treatment-resistant schizophrenia is defined (TRRIP consensus) as persistent symptoms despite at least two adequate trials of different antipsychotics, each at a therapeutic dose for at least 6 weeks with confirmed adherence. Clozapine is the only antipsychotic with proven superior efficacy in this group, so it is the recommended next step (NICE, APA 2020), with baseline and regular neutrophil monitoring. Her ANC of 2,100/mm³ is above the 1,500/mm³ starting threshold.
8A 31-year-old woman experiences severe depressive episodes alongside auditory hallucinations. Which criterion is essential to establish a diagnosis of schizoaffective disorder rather than major depressive disorder with psychotic features?
A.Psychotic symptoms that only occur during the peaks of severe depressive mood episodes
B.Rapid resolution of all psychotic symptoms upon commencement of antidepressant monotherapy
C.Continuous depressive mood symptoms that persist for at least 2 consecutive years
D.Delusions or hallucinations persisting for at least 2 weeks in the absence of a major mood episode
Explanation: To fulfill DSM-5 criteria for schizoaffective disorder, there must be a lifetime period of delusions or hallucinations lasting at least 2 weeks in the absence of a major mood episode (depressive or manic). If psychotic symptoms occur exclusively during mood episodes, the correct diagnosis is major depressive disorder (or bipolar disorder) with psychotic features. Additionally, mood symptoms must be present for the majority of the total active and residual duration of the illness.
9A 40-year-old man with schizophrenia and pre-existing type 2 diabetes mellitus requires antipsychotic therapy. Which of the following second-generation antipsychotics has the lowest propensity for causing weight gain and metabolic dysregulation?
A.Olanzapine
B.Aripiprazole
C.Clozapine
D.Quetiapine
Explanation: Aripiprazole (along with ziprasidone and lurasidone) is recognized as having a low risk of metabolic syndrome, weight gain, and dyslipidemia due to its partial agonism at dopamine D2 and 5-HT1A receptors and weak affinity for histamine H1 and 5-HT2C receptors. In contrast, clozapine and olanzapine carry the highest risk of severe metabolic side effects, followed by quetiapine, making aripiprazole a far safer choice in diabetic patients.
10A 45-year-old accountant firmly believes that a famous television presenter has fallen deeply in love with him and is sending covert romantic messages through television broadcasts. He has no other psychiatric symptoms, performs well at work, and maintains his finances. What is the most likely diagnosis?
A.Schizophrenia, paranoid subtype
B.Histrionic personality disorder
C.Delusional disorder, erotomanic type
D.Bipolar I disorder with manic psychosis
Explanation: Delusional disorder is characterized by the presence of one or more non-bizarre or bizarre delusions lasting for at least 1 month in the absence of marked functional impairment, prominent hallucinations, or other psychotic symptoms of schizophrenia. The erotomanic subtype specifically involves the unshakeable conviction that another person, usually of higher social or celebrity status, is romantically in love with the patient. Cognitive and occupational functioning outside the direct sphere of the delusion are typically preserved.
