What is DID?
- Dissociative identity disorder. This condition, formerly known as multiple personality disorder, is characterized by "switching" to alternate identities when you're under stress. In dissociative identity disorder, you may feel the presence of one or more other people talking or living inside your head. Each of these identities may have their own name, personal history and characteristics, including marked differences in manner, voice, gender and even such physical qualities as the need for corrective eyewear. There often is considerable variation in each alternate personality's familiarity with the others. People with dissociative identity disorder typically also have dissociative amnesia.
- The altered personalities are often referred to as either being awake or asleep when one alter is describing another.
- Dissociative amnesia. Memory loss that's more extensive than normal forgetfulness and can't be explained by a physical or neurological condition is the hallmark of this condition. Sudden-onset amnesia following a traumatic event, such as a car accident, happens infrequently. More commonly, conscious recall of traumatic periods, events or people in your life — especially from childhood — is simply absent from your memory.
