Amnesia in Various Other Victim Populations


Amnesia in Various Other Victim Populations
In every study that actually looked at amnesia, it was found. There was not a single study that actually asked about amnesia that did not find some segment of the trauma population who experienced it. Many articles on PTSD were concerned with broadly categorized symptoms such as intrusion and avoidance. Few studies actually asked about amnesia in large sample studies until recently. Reports of amnesia were generally (but not always) given as case studies. 

MALE RAPE VICTIM

MS ESTONIA FERRY ACCIDENT (1994)

 Eriksson, N-G, Lundin, T. (1996). Early traumatic stress reactions among Swedish survivors of the MS Estonia disaster. British Journal of Psychiatry, 169, (6), 713-716.

42 survivors. 43% had emotional numbing; 55% had reduction in awareness; 67% had derealization; 33% had depersonalization; and 29% had dissociative amnesia. All dissociative symptoms were predictive of posttraumatic reactions. This study substantiates the importance of assessing dissociative symptoms during a life threatening event as a possible predictor for later posttraumatic reactions and possible PTSD.

Kinzie (1986). (children in Cambodian concentration camps). Journal of the American Academy of Child Psychiatry, 25, 370-376.

Children have "poor recall or difficulty in recalling". 58% "avoided" memories of Cambodia. The authors, who do not discuss memory, note that massive avoidance and denial were very helpful in helping the children cope and the major factor in helping the children avoid severe PTSD was family.

 

CAMBODIAN AND OTHER SOUTHEAST ASIA REFUGEES

Carlson, E. (Nov, 1991). Trauma experiences, posttraumatic stress, dissociation and depression in Cambodian refugees. American Journal of Psychiatry, 148 (11), 1548-1551.
            50 female and 24 male refugees randomly selected from 500 throughout the US. Although only 1 in 50 had received professional mental health intervention, 86% met DSM-III-R criteria for PTSD.. Mean DES score was 37.1 (Range, 9.3-88.6, SD, 16.1). Only two in the sample had a DES in the normal range. The mean of 37.1 was exceeded in PTSD samples of veterans in only 1 (Branscomb, 1991) out of 5 such studies. "There was a high rate of dissociative symptoms in this group, but such symptoms are seldom noted or studied in trauma victims." The distribution of this sample of above average DES scores "supports the view that dissociation is a universal response to traumatic experiences."

Includes citation of a report of 20 cases by Charles Fisher in The Psychoanalytic Quarterly, 14, 4437-4468. "The war neuroses of WW II provide ample evidence that repression does indeed occur, and that the recovery of these traumatic memories and their related effects led to remission of symptoms."
