Dissociation

Dissociation is a term that is used both as a psychiatric 'symptom' and a 'diagnostic category' for a group of psychiatric disorders (illnesses).

As a SYMPTOM, dissociation includes the following:

  • A subjective sense of numbing, detachment or absence of normal emotional responsiveness.
  • a reduced sense of personal awareness of one's surroundings (i.e. being a daze).
  • Depersonalization feelings: Feeling that somehow one's body has changed or does not feel real or that it is not “attached”. Some may feel that they have briefly left their body (“out of body experience”) and may experience themselves as if looking at their body from a distance.
  • Derealization feelings: Feeling that some how the outside world has changed and seems unreal, foggy, two dimensional or dream-like in quality.
  • Amnesia: (a loss of memory for a discrete period of time, often caused by stress or psychological trauma (as opposed to a head injury or effects of alcohol or drugs).
  • Somatoform dissociation: is a term sometimes used by therapists and refers to bodily sensations that can be present (i.e. body memory pains, psychosomatic symptoms) or absent (i.e. loss or decreased body sensation). Such symptoms are based on psychological factors in the absence of physical causes.

As a DISORDER, dissociation has been divided into five diagnoses (DSM-IV, 1994):

1. Dissociative Amnesia

This disorder used to be called “psychogenic amnesia” and refers to experiences of 'blackouts' or 'time losses' which are more prominent than just everyday forgetting. Individuals with dissociative amnesia may “come to awareness” realizing that a lot of time has passed (i.e. minutes, hours, or rarely days) without having any memory of that lost period of time. Others may point these time losses out to the individual. These time gaps become distressing as the person becomes aware that have no memory of these periods. The time losses cannot be explained by substance use (i.e. excessive alcohol, medications) or a physical problem (i.e., a seizure disorder or head trauma). For this disorder, amnesia is the primary problem. If other dissociative experiences are also present, other dissociative disorders may need to be considered.

2. Dissociative Fugue

This disorder was previously referred to as “psychogenic fugue.” In this condition, amnesia is present, but in addition the person may travel extensive distances and end up in a different place, city or even a different country without any memory of how they got there. The amnesia for this travel period may be hours, days, or even months. If the person is seen during this period, they may have assumed a different identity, having forgotten their real identity and where they live. Sometimes this “fugue” (a word meaning rapid travel) may be triggered by a personal trauma. The fugue may end abruptly with the person suddenly finding themselves in a totally unknown place and not knowing how they got there nor how long they were there. Some may try to sort the puzzle out themselves and get back to their normal environment without telling others. Others may be so distressed they may seek help from the police or a medical institution. When seen by health care professionals, they usually cannot recall the events which occurred while they were in this fugue state.

3. Dissociative Identity Disorder (DID)

In the recent past, this disorder was referred to as multiple personality disorder (MPD). In addition to amnesia and fugue behavior, individuals with DID may experience (or be told) they have different personality states which take control of their behavior. The person may have no memory when this other “state” or “states” take control of their life (often only learning about this when later being told by other people). Sometimes the person may be aware when a personality state is its control, yet be helpless to stop it. In this case, one is aware (co-conscious) but essentially helpless to stop the action and words of this controlling state. For some, it may feel like they are “possessed” by another being. However it is important to emphasize that DID is not possession, nor are the personality states separate “people”. In reality, normal personality is a smooth coordination of various emotional and functioning styles of behavior. If the normal blending of personality styles is interfered with (usually as a result of repeated physical or psychological trauma in the early childhood developmental years) then normal diverse behavior patterns do not evolve into a unitary personality. The interference may lead to development progressing in a disjointed and disconnected manner and over the years and may lead to a sense of being “separate” from other parts of self. Each state (sometimes called “ego states” or “personality states”) may believe itself to be a separate “person” rather than the reality of being only one “part/aspect” of that “person”. (Normal personality is a blended group of personality “styles” or “states”). It is often initially difficult to help these ego states realize they are not separate people. They sometimes believe the therapist really wants to eliminate them - which is really neither possible nor sensible.

Dissociative Identity Disorder is a treatable condition though psychotherapy may take considerable time (i.e. weekly sessions for a year or more). In brief, the intent of therapy is to help correct this major misconception of separate existence and to help all of these states to blend (unite) into the full personality they were intended to be, each adding their own skills to this new combination of “ego states”.

In addition to dissociative symptoms, other psychiatric conditions (such as depression, panic attacks, substance abuse, eating disorders and posttraumatic stress disorder) frequently occur with DID. Although at present there does not seem to be any medications that directly target dissociation, the other psychiatric conditions may be treated with medications.

4. Depersonalization Disorder

This disorder is characterized by a persistent and recurrent feeling as if one’s body does not seem real or fully attached, to the extent that this interferes with functioning. It may include “out of body” experiences or feeling as if parts of the body are unattached, changed, or numb.. Depersonalization disorder can sometimes be associated with a feeling of derealization in which the outside world feels unreal, fog-like or two dimensional. Depersonalization experiences can occur in other dissociative disorders and in other medical conditions such as temporal lobe seizure. This diagnosis should not be made if it is part of such other conditions.

5. Dissociative Disorder Not Otherwise Specified (DDNOS)

This is a category for other conditions which do not fit into the above four dissociative disorders. For instance if there is derealization without depersonalization DDNOS would be the proper diagnosis. Cases that are like DID but do not show the exact characteristics would fit into this category as would conditions in which there appears to be some outside force controlling ones actions i.e. , a feeling of “possession”. These feelings of outside influences may have special cultural interpretations which are then called dissociative trance disorders.

Treatment of Dissociative Disorders

Dissociative disorders are treatable but may require special strategies including ego-state therapy, guided imagery and hypnosis, as well as medications when other conditions like depression and anxiety disorders exist. Not all therapists are familiar with these strategies and not all therapists agree that dissociative disorders exist (in spite of being official diagnoses with the American Psychiatric Association and the World Health Organization).
