Anyone with an interest in psychology may find dissociative disorder to be fascinating. A person who suffers from dissociative disorder involves disruptions or breakdowns in the memory, awareness, identity or perception for the sufferer. Typically the person can function on a normal basis, until the dissociative disorder appears. Then the person is unable to function as they had before.

There are different types of dissociative disorder. Depersonalization disorder is where a person detaches from self or surroundings feeling that they are not a part of reality. Dissociative identity disorder is where a person may have one or more alternate personalities. Dissociative amnesia is a dissociative disorder where the person has an impairment recalling events from a trauma, most often emotional rather than being physically related.
