Clinical Information
  • A disorder characterized by the presence of two or more identities with distinct patterns of perception and personality which recurrently take control of the person's behavior; this is accompanied by a retrospective gap in memory of important personal information that far exceeds ordinary forgetfulness. The changes in identity are not due to substance use or to a general medical condition.
  • A dissociative disorder in which the individual adopts two or more distinct personalities. Each personality is a fully integrated and complex unit with memories, behavior patterns and social friendships. Transition from one personality to another is sudden.
