Definition of Dissociation and Multiple Personality Disorders

Dissociation is a word that is used to describe the disconnection or lack of connection between things usually associated with each other. Dissociated experiences are not integrated into the usual sense of self, resulting in discontinuities in conscious awareness (Anderson & Alexander, 1996; Frey, 2001;

International Society for the Study of Dissociation, 2002; Maldonado, Butler, & Spiegel, 2002; Pascuzzi & Weber, 1997; Rauschenberger & Lynn, 1995; Simeon et al., 2001; Spiegel & Cardeña, 1991; Steinberg et al., 1990, 1993).

In severe forms of dissociation, disconnection occurs in the usually integrated functions of consciousness, memory, identity, or perception. For example, someone may think about an event that was tremendously upsetting yet have no feelings about it. Clinically, this is termed emotional numbing, one of the hallmarks of post-traumatic stress disorder. Dissociation is a psychological process commonly found in persons seeking mental health treatment (Maldonado et al., 2002).

Dissociation may affect a person subjectively in the form of “made” thoughts, feelings, and actions. These are thoughts or emotions seemingly coming out of nowhere, or finding oneself carrying out an action as if it were controlled by a force other than oneself (Dell, 2001).

Typically, a person feels “taken over” by an emotion that does not seem to makes sense at the time. Feeling suddenly, unbearably sad, without an apparent reason, and then having the sadness leave in much the same manner as it came, is an example. Or someone may find himself or herself doing something that they would not normally do but unable to stop themselves, almost as if they are being compelled to do it. This is sometimes described as the experience of being a “passenger” in one’s body, rather than the driver

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. Many labeled with mpd seek mental health treatment programs to help manage the disorder. Another symptom of MPD is significant amnesia which can't be explained by ordinary forgetfulness. In 1994, the American Psychiatric Association's DSM-IV replaced the designation of MPD with DID: dissociative identity disorder. The label may have changed, but the list of symptoms remained essentially the same.

Memory and other aspects of consciousness are said to be divided up among "alters" in the MPD. The number of "alters" identified by various therapists ranges from several to tens to hundreds. There are even some reports of several thousand identities dwelling in one person. There does not seem to be any consensus among therapists as to what an "alter" is. Yet, there is general agreement that the cause of MPD is repressed memories of childhood sexual abuse. The evidence for this claim has been challenged, however, and there are very few reported cases of MPD afflicting children
