Amnesia refers to the inability to recall important personal information that is so extensive that it is not due to ordinary forgetfulness. Most of the amnesias typical of dissociative disorders are not of the classic fugue variety, where people travel long distances, and suddenly become alert, disoriented as to where they are and how they got there.

Dissociative effects include distorted perceptions of sight and sound as well as feelings of detachment or separation from the environment and self.

The next stage in the recovery from head injury is called POST-TRAUMATIC AMNESIA. Coming out of coma is not just waking up as people often imagine. Rather, it is most often a gradual process of regaining contact with the world. One of the most striking things about recovery of conscioiusness is that it take so long to begin to restore memory. The kind of memory that is most often affected is the ability to continuously remember the events of the day.

Some studies indicate that diagnosable dissociation occurs in approximately two to three percent of the general population. Other studies have estimated a prevalence rate of 10% for all dissociative disorders in the general population (e.g., Loewenstein, 1994). Dissociation may exist in either acute or chronic forms. Immediately following severe trauma, the incidence of dissociative phenomena is remarkably high.

Research tends to show that dissociation stems from a combination of environmental and biological factors. The likelihood that a tendency to dissociate is inherited genetically is estimated to be zero (Simeon et al., 2001). Most commonly, repetitive childhood physical and/or sexual abuse and other forms of trauma are associated with the development of dissociative disorders (e.g., Putnam, 1985).

There are four main categories of dissociative disorders as defined in the standard catalogue of psychological diagnoses used by mental health professionals in North America, the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR).

For moments, yes. Long term? Rarely. The idea of causing people to forget something is, broadly speaking, something that has no therapeutic value.

DID is a defense mechanism used solely for survival. It is created by highly creative and intelligent children in order to protect themselves from severe repeated trauma, usually sexual abuse by a loved one, that usually begins before the age of 5. Only young children have the ability to create alter personalities. These children dissociate themselves from their current situation (the abuse) and "go inside themselves." Here they create other children to take the abuse for them.
