Review the following psychiatric clinical scenarios and correlate each presentation with the most accurate DSM-5 diagnostic classification.
- A 34-year-old woman experiences auditory hallucinations and persecutory delusions for 3 weeks following the sudden death of her spouse, after which she completely returns to her previous baseline.Brief psychotic disorder
- A 25-year-old man exhibits disorganized speech, flattened affect, and delusions of being continuously monitored by the government for the past 8 months, accompanied by a severe decline in occupational functioning.Schizophrenia
- A 41-year-old man functions well at his accounting job but has firmly believed for the past 6 months that his neighbor is secretly poisoning his water supply. He exhibits no hallucinations or disorganized behavior.Delusional disorder
- A 29-year-old woman presents with a 4-month history of prominent auditory hallucinations and severe social withdrawal, with no history of major depressive or manic episodes.Schizophreniform disorder
Cevap
The correct correlations rely heavily on the timeline of symptoms: <1 month is brief psychotic disorder, 1-6 months is schizophreniform disorder, >6 months is schizophrenia, and isolated delusions without other psychotic symptoms point to delusional disorder.
Each diagnosis is accurately determined by strictly adhering to the DSM-5 duration criteria and specific symptom profiles. Brief psychotic disorder requires symptoms lasting less than 1 month, schizophreniform disorder lasts 1 to 6 months, schizophrenia requires at least 6 months of symptoms, and delusional disorder is characterized by isolated delusions for >1 month without the global functional decline or other prominent psychotic symptoms seen in schizophrenia.
