What is the typical duration of Brief Psychotic Disorder with full return to premorbid functioning?

• A. Lasts less than 1 day
• B. Lasts 1 day to 1 month with full return to premorbid level of function
• C. Lasts 1 month to 6 months
• D. Lasts more than 6 months

Answer: (B)

Brief Psychotic Disorder is defined by a sudden onset of psychotic symptoms that last for a brief period and then remit completely, returning the person to their prior level of functioning. The critical timeframe is at least one day but less than one month. If symptoms persist beyond one month, the diagnosis changes to a longer-lasting psychotic disorder (schizophreniform if 1–6 months, or schizophrenia if longer). That’s why the best choice describes a duration of 1 day to 1 month with full return to premorbid functioning.
