Schizophrenia is diagnosed when prominent delusions or hallucinations are present along with other required symptoms.

• A. False
• B. Not necessarily
• C. True
• D. Only with catatonia

Answer: (C)

Schizophrenia is defined by a cluster of psychotic symptoms, not by a single feature. The diagnosis requires at least two of the core symptoms—delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, and negative symptoms—for a substantial period, with at least one of the first three symptoms (delusions, hallucinations, or disorganized speech) being present. These symptoms must persist for a significant time (typically at least 6 months, with active symptoms lasting at least 1 month) and cause clear functional impairment. Catatonia can occur but is not required for the diagnosis, and it does not mean schizophrenia is present only if catatonia is involved. Therefore, having prominent delusions or hallucinations along with other defined symptoms fits the diagnostic criteria, making the statement true.
