Dissociative identity disorder (DID), previously known as multiple personality disorder(MPD), is a mental disorder characterized by the maintenance of at least two distinct and relatively enduring personality states. The disorder is accompanied by memory gaps beyond what would be explained by ordinary forgetfulness.
Mental health professionals recognise four main types of dissociative disorder, including:
- Dissociative amnesia.
- Dissociative fugue.
- Depersonalisation disorder.
- Dissociative identity disorder.
