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.
DID is associated with long-term exposure to trauma, often chronic traumatic experiences during early childhood. It is often misunderstood and portrayed incorrectly in popular media.
