What best describes Brief Psychotic Disorder?

Brief Psychotic Disorder is characterized by a sudden onset of at least one psychotic symptom, which can include delusions, hallucinations, and disorganized speech or behavior. To qualify for this diagnosis, the duration of these symptoms must last for more than one day but less than one month, after which there is a full return to premorbid functioning. The emphasis on the sudden onset is crucial to distinguishing this disorder from other psychotic disorders that have a longer duration or underlying chronic conditions.

The symptoms must be severe enough to cause significant distress or impairment in social, occupational, or other important areas of functioning. This distinguishes Brief Psychotic Disorder from other disorders with longer-lasting symptoms, which would not meet the criteria for this specific diagnosis. In contrast, the other options do not accurately reflect the definition or diagnostic criteria for Brief Psychotic Disorder, as they either describe symptoms of longer duration or encompass different psychiatric conditions entirely.
