Abstract

The dissociative disorders, as listed in the current (4th) edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR; American Psychiatric Association, 2000), include a number of different syndromes, all of which entail an alteration in consciousness affecting memory and identity. Patients with dissociative amnesia (formerly known as psychogenic or functional amnesia) cannot remember certain past experiences (episodic memory), while those with dissociative fugue (formerly known as psychogenic fugue) also lose their personal identities (semantic memory). Patients with dissociative identity disorder (DID; formerly known as multiple personality disorder, or MPD) alternate between two or more separate identities (selves, or “alter egos”), each with its associated fund of autobiographical memory—and an interpersonality amnesia separating at least one alter ego from the others.
