Multiple Personality Disorder

Beyond having different personality states, symptoms of Dissociative Identity Disorder include nightmares, flashbacks, hearing voices, and experiencing memory gaps. The frequency of Dissociative Identity Disorder is about 1 to 3 percent of the general population, similar to the number of people with schizophrenia or bipolar disorder. Women are more likely than men to be diagnosed with Dissociative Identity Disorder.

Treatment for Dissociative Identity Disorder focuses on reuniting the fragmented personalities within the psyche through long-term psychotherapy. Cognitive Behavioral Therapy, Dialectical Behavioral Therapy, and creative therapy modalities have been found to be useful for those with DID. Research shows that treatment can help people with DID live functional and fulfilling lives.
