What is the minimum duration of continuous signs required for a schizophrenia diagnosis according to DSM-5?

• A. 1 month
• B. 3 months
• C. 6 months
• D. 12 months

Answer: (C)

In DSM-5, the duration of symptoms is what matters. Schizophrenia requires a continuous disturbance for at least six months, and within that period there must be at least one month of active-phase symptoms (such as delusions, hallucinations, or disorganized speech). The remaining time can include prodromal or residual symptoms. This six-month minimum helps distinguish schizophrenia from other psychotic disorders that have shorter durations, like brief psychotic disorder or schizophreniform disorder.
