Psychotic Disorder Not Otherwise Specified

This category includes psychotic symptomatology (i.e., delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior) about which there is inadequate information to make a specific diagnosis or about which there is contradictory information, or disorders with psychotic symptoms than do not meet the criteria for any specific Psychotic Disorder.

Examples include:

  1. Postpartum psychosis that does not meet criteria for Mood Disorder With Psychotic Features, Brief Psychotic Disorder, Psychotic Disorder Due to a General Medical Condition, or Substance-Induced Psychotic Disorder.
  2. Psychotic symptoms that have lasted for less than 1 month but that have not yet remitted, so that the criteria for Brief Psychotic Disorder are not met.
  3. Persistent auditory hallucinations in the absence of any other features
  4. Persistent nonbizarre delusions with periods of overlapping mood episodes that have been present for a substantial portion of the delusional disturbance
  5. Situations in which the clinician has concluded that a Psychotic Disorder is present, but is unable to determine whether it is primary, due to a general medical condition, or substance induced
