Dissociative identity disorder (DID), previously known as multiple personality disorder, is a complex psychological condition characterized by the presence of two or more distinct identities or personality states within an individual. These identities can have their own unique behaviors, memories, and perceptions, and may take control of the individual's behavior at different times. The condition typically arises as a result of severe trauma in childhood.
