Key diagnostic criteria

  • 1+ of: delusions, hallucinations, disorganized speech, grossly disorganized/catatonic behavior
  • Duration: 1 day to 1 month
  • Full return to premorbid functioning
  • Not better explained by MDD/bipolar with psychotic features, schizophrenia, or substance effects

Documentation essentials

Document onset, specific symptoms, duration, precipitating factors, and return to baseline.

Differential diagnosis

Distinguish from schizophrenia (duration), substance-induced psychosis, delusional disorder, and psychotic mood disorders.

Treatment planning

Short-term antipsychotic medication. Supportive therapy. Crisis management. Monitor for progression to other psychotic disorders.
