Psychotic Disorder: Not Otherwise Specified (NOS)
The category of psychotic disorder: not otherwise specified 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 that do not meet the criteria for any specific psychotic disorder.
- Postpartum psychosis
- 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
- Persistent auditory hallucinations in the absence of any other features
- Persistent nonbizarre delusions with periods of overlapping mood episodes that have been present for a substantial portion of the delusional disturbance
- Situations in which the clinician has concluded that some type of psychotic disorder may be present, but is unable to determine whether it is primary, due to a general medical condition, or substance induced
*Note: This disorder (DSM-IV) is listed here now for historical/informational purposes. It has been revised under the name “other specified schizophrenia spectrum and other psychotic disorder” in the updated 2013 DSM-5. See other specified schizophrenia spectrum and other psychotic disorder criteria.
