Dissociative Disorder Not Otherwise Specified is a category for dissociation that matches the DSM-IV criteria for a dissociative disorder, but does not fit the criteria for any of the specifically identified subtypes, which include depersonalization disorder, dissociative amnesia, dissociative fugue, and dissociative identity disorder.
Disorders that are under this category include Ganser's syndrome, some variants of multiple personality disorder, and trance states.[1]
