Memory and learning performances in POW survivors with history of malnutrition and combat veteran controls.
Former prisoners of war (POWs) with histories of malnutrition and body wasting were compared on standardized measures of memory and learning with POW survivors who sustained less confinement body weight loss and combat veterans of similar ages and military assignments. Results showed that POWs who sustained the greatest degree of trauma-induced weight loss, or that exceeding 35% of their precaptivity body weights, performed significantly worse on four of the five Wechsler Memory Scale /3-Revised (WMS-R) indices, showed more rapid rates of forgetting on the Visual Reproduction test, and exhibited slower acquisition rates and less sophisticated mastery of the learning materials on a modified version of the Rey Auditory Verbal Learning Test (AVLT). Given their relatively intact performances on measures of general intelligence and attention-concentration, the POWs with a history of severe malnutrition appeared to evidence a pattern of cognitive limitations qualitatively similar to that associated with alcoholic Korsakoff's syndrome.
