Trauma-induced weight loss and cognitive deficits among former prisoners of war.

Abstract

Former prisoners of war (POWs) from the Korean Conflict and WWII reporting confinement weight losses of greater than 35% (n = 60) and less than or equal to 35% (n = 113) and non-POW combat veterans (n = 50) were compared on WAIS-R and Wechsler Memory Scale (WMS) Logical Memory indices. High weight-loss POWs performed more poorly than combat veterans on Performance IQ, Arithmetic, Similarities, and Picture Completion subtests, Witkin-Goodenough Attention-Concentration Factor, and WMS Immediate and Delayed Recall and more poorly than low weight-loss POWs on Arithmetic, Attention-Concentration Factor, and the WMS immediate memory measure. Low weight-loss POWs and combat veterans differed only on WMS immediate memory. Findings support the Thygesen, Hermann, and Willanger (1970) hypothesis that severity of POW confinement stress reflected by trauma-induced weight loss is predictive of long-term compromise in cognitive performance.
