Background Information

Demon possession has been around since BCE and has since been renamed Multiple Personality Disorder, or Dissociative Identity Disorder. Studies show that multiple personality behaviors have been around and recorded for over 100 years, but were not medically diagnosed until about 35 years ago. It is common for people with Dissociative Identity Disorder to not remember anything they did when in an alter personality. This, called one-way amnesia, occurs when the present personality is amnesic for periods when alter personalities are in control of the body. In most cases, alter personalities are fully aware of present personalities.

Treatments and Medication

There is no medication proven to help Dissociative Identity Disorder, but many patients take benzodiazepine (helps calm anxiety), antidepressants, antipsycotics, lithium (used for bipolar disorder), and/ or electroconvulsive therapy. Some patients may take only one of these medications while others may take all and more because many people with Dissociative Identity Disorder are not diagnosed or have been diagnosed for another illness.
