Cognitive functioning and posttraumatic stress disorder
Abstract
OBJECTIVE: The authors examined the association of cognitive impairment with posttraumatic stress disorder (PTSD) and other psychiatric diagnoses known to affect cognitive functioning. METHOD: The results of standardized neuropsychological tests were compared in four groups of Vietnam veterans: veterans with both a lifetime history of PTSD and a current diagnosis of depression, anxiety, or substance abuse; veterans with only a PTSD diagnosis; veterans with only a current diagnosis of depression, anxiety, or substance abuse; and veterans with none of these diagnoses. RESULTS: Veterans with both PTSD and concurrent diagnoses. exhibited more impairment in cognitive functioning than did veterans without these diagnoses. CONCLUSIONS: Cognitive deficits seen among persons diagnosed with PTSD may be associated with their concomitant diagnoses.
