Brief Psychotic Disorder is characterized by the presense of one or more of the following symptoms:

• Delusions
  
• Hallucinations
  
• Disorganized speech (e.g., frequent derailment or incoherence)
  
• Grossly disorganized or catatonic behavior

Duration of an episode of brief psychosis is at least one day but less than one month, with eventual full return to previous 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.
