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 a treatable disorder once it is properly diagnosed. Clinicians who understand DID symptoms can diagnose DID in the clinical interview. There are also paper and pencil tests that can help clinicians diagnose DID and other dissociative disorders. Studies show that DID symptoms improve over time when treated using Phasic Trauma Treatment.
