Brief Psychotic Disorder
Presence of one (or more) of the following symptoms:
- disorganized speech (e.g., frequent derailment or incoherence)
- grossly disorganized or catatonic behavior
Note: Do not include a symptom if it is a culturally sanctioned response pattern.
Duration of an episode of the disturbance is at least 1 day but less than 1 month, with eventual full return to premorbid level of functioning.
The disturbance is not better accounted for by a Mood Disorder With Psychotic Features, Schizoaffective Disorder, or Schizophrenia and is not due to the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a general medical condition.
