Dissociative identity disorder (DID) is the disorder that was previously recognized as multiple personality disorder. It’s characterized by the presence of two or more dissociated self states, known as alters, that have the ability to take executive control and are associated with some degree of inter-identity amnesia. DID is caused by chronic childhood trauma and is highly associated with posttraumatic stress disorder.

“As an undergraduate student in psychology, I was taught that multiple personalities were a very rare and bizarre disorder. That is all that I was taught on ... It soon became apparent that what I had been taught was simply not true. Not only was I meeting people with multiplicity; these individuals entering my life were normal human beings with much to offer. They were simply people who had endured more than their share of pain in this life and were struggling to make sense of it.”
