Psychotic Disorder NOS
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 that do not meet the criteria for any specific psychotic disorder.
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.
