Dissociative Identity Disorder, also known as multiple personality disorder, is a condition where a person's personality is separated into more than one personality states. This disease is rare, but it is usually found in victims of severe abuse. Some people with this disease describe it as an "experience of possession." Most people with DID have an inability to remember important personal information. There are also distinct memory variations, which change with the person's split personality. Each personality has their own identity. As each personality reveals itself and takes control, it is known as "switching." Switching can take anywhere from seconds to days. There is no cure for DID, but therapists help ease the switching and the symptoms of the disease. If you or a loved one is suffering from DID, seek help and support from the community.
