Cevap

The correct matches are based on symptom duration and the relationship between mood and psychotic symptoms: Brief psychotic disorder (<1 month), Schizophreniform disorder (1-6 months), Schizoaffective disorder (psychosis independent of mood episodes), and Delusional disorder (isolated delusions).
Each psychiatric diagnosis is defined by specific temporal and symptomatic criteria as established in the DSM-5. Brief psychotic disorder is characterized by symptoms lasting less than 1 month with full recovery. Schizophreniform disorder requires symptoms lasting between 1 and 6 months. Schizoaffective disorder requires a major mood episode concurrent with active-phase psychotic symptoms, plus a distinct period of at least 2 weeks of delusions or hallucinations without prominent mood symptoms. Delusional disorder involves at least 1 month of delusions without meeting criteria for schizophrenia, and functioning is not markedly impaired.

Adım Adım Çözüm

1
Evaluate the duration of psychotic symptoms for each patient.
The patients have symptoms lasting 2 weeks, 4 months, 2 years, and 1 year, respectively.
Duration is the primary diagnostic differentiator for brief psychotic disorder (<1 month), schizophreniform disorder (1-6 months), and schizophrenia (>6 months).
2
Assess the temporal relationship between mood symptoms and psychosis.
The patient with a 2-year history of hallucinations maintains these symptoms even when not depressed.
Psychosis occurring for >2 weeks without concurrent mood symptoms rules out a major mood disorder with psychotic features, confirming schizoaffective disorder.
3
Determine the breadth of symptoms and level of functional impairment.
The 45-year-old woman has an isolated false belief without negative symptoms or global dysfunction.
Isolated delusions without other psychotic features or marked functional decline are the hallmark of delusional disorder.
