Cevap

The 22-year-old graduate student matches with Schizophreniform disorder; the 47-year-old accountant matches with Delusional disorder; the 28-year-old woman matches with Schizoaffective disorder; and the 19-year-old freshman matches with Brief psychotic disorder.
Each presentation strictly corresponds to DSM-5 timeline and criteria for psychotic disorders: <1 month is brief psychotic disorder, 1-6 months is schizophreniform disorder, >1 month of isolated delusions is delusional disorder, and psychosis independent of mood episodes characterizes schizoaffective disorder.

Adım Adım Çözüm

1
Analyze the duration and symptom profile for the first presentation.
Symptoms match schizophrenia but have only lasted 3 months.
Duration between 1 and 6 months distinguishes schizophreniform disorder from schizophrenia (which requires >6 months).
2
Evaluate the second presentation focusing on functioning and symptom scope.
Isolated delusion for >1 month with preserved functioning.
These are the core criteria for delusional disorder.
3
Assess the third presentation for the relationship between psychosis and mood.
Psychosis occurs both with and without a mood episode (at least 2 weeks of psychosis without mood symptoms).
This temporal relationship is necessary to diagnose schizoaffective disorder.
4
Examine the fourth presentation's onset and duration.
Acute onset following a stressor, resolving within 18 days.
Psychotic symptoms lasting less than 1 month followed by full recovery characterize brief psychotic disorder.
