What is dissociative identity disorder (DID)?

Dissociative identity disorder (DID) is a mental health condition. People with DID have two or more separate identities. These personalities control their behavior at different times. Each identity has its own personal history, traits, likes and dislikes. DID can lead to gaps in memory and hallucinations (believing something is real when it isn’t).

Dissociative identity disorder used to be called multiple personality disorder or split personality disorder.

DID is one of several dissociative disorders. These disorders affect a person’s ability to connect with reality. Other dissociative disorders include:

  • Depersonalized or derealization disorder, which causes a feeling of detachment from your actions.
  • Dissociative amnesia, or problems remembering information about yourself.
