Multiple Personality Disorder

What Is It?

Multiple personality disorder (MPD) is a psychiatric disorder characterized by having at least one "alter" personality that controls behavior. The "alters" are said to occur spontaneously and involuntarily, and function more or less independently of each other. The unity of consciousness, by which we identify our selves, is said to be absent in MPD. Another symptom of MPD is significant amnesia which can't be explained by ordinary forgetfulness

The defenders of the MPD/DID standard model of genesis, diagnosis and treatment argue that the disease is underdiagnosed because its complexity makes it very difficult to identify. Dr. Philip M. Coons, who is in the Department of Psychiatry at the Indiana University School of Medicine, claims that "there is a professional reluctance to diagnose multiple personality disorder." He thinks this "stems from a number of factors including the generally subtle presentation of the symptoms, the fearful reluctance of the patient to divulge important clinical information, professional ignorance concerning dissociative disorders, and the reluctance of the clinician to believe that incest actually occurs and is not the product of fantasy." Dr. Coons also claims that demonic possession was "a forerunner of multiple personality."
