Dissociative Disorders are disorders such as psychogenic fugue, multiple personality, and psychogenic amnesia in which a person’s conscious awareness becomes separated (dissociated) from previous memories, thoughts, and feelings. When this happens, the person is unable to recall certain events that happened in their lives. For example, you may have heard of people committing heinous crimes and them claiming to have no recollection whatsoever of the event. This would be a case of psychogenic amnesia.
