Other and unspecified dissociative disorders
Other specified dissociative disorder (OSDD) and Unspecified dissociative disorder are two diagnostic categories for dissociative disorders (DDs) defined in the fifth edition (DSM-5) of the Diagnostic and Statistical Manual of Mental Disorders for individuals experiencing pathological dissociation that does not meet the full criteria for any specific dissociative disorder, such as dissociative identity disorder or depersonalization-derealization disorder.[1] These two categories replaced the earlier Dissociative Disorder Not Otherwise Specified (DDNOS) used in the DSM-IV and DSM-IV-TR.
OSDD is used when the clinician can identify the reason why the presentation doesn’t fit a specific diagnosis, such as mixed dissociative symptoms or identity disturbance following coercive persuasion. A diagnosis of unspecified dissociative disorder is given when this reason is not specified.[1]
Like other dissociative disorders, these conditions are often trauma-related[2] and may co-occur with other mental health diagnoses.[3][4] Dissociative conditions appear to respond well to psychotherapy. There are currently no drugs available that treat dissociative symptoms directly.[5][6]
