What is the minimum duration of continuous disturbance required for a schizophrenia diagnosis?

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

Answer: (C)

Schizophrenia requires a sustained disturbance in thinking, perception, and behavior for at least six months, with at least one month of active-phase symptoms (such as delusions, hallucinations, or disorganized speech) during that period. The remaining months can include prodromal or residual symptoms that are milder. If the disturbance lasts less than six months, the diagnosis would be a different schizophrenia-spectrum condition (for example, schizophreniform disorder when it’s between one and six months, or a brief psychotic disorder when it’s less than one month). This six-month duration helps distinguish more persistent schizophrenia from shorter-lived psychotic conditions.
