| Abstract | This study tested the hypothesis that combat veterans with posttraumatic stress disorder (PTSD) experience sympathetic nervous system activation in response to war-related laboratory stimuli. Circulating plasma catecholamines, vital signs, and affect ratings were measured in 10 Vietnam combat veterans with PTSD and 11 control subjects, during and after viewing combat and noncombat stress films. PTSD subjects responded more strongly than controls to the combat film, with greater increases in plasma epinephrine, pulse, blood pressure, and subjective distress. The increases in autonomic activity of PTSD subjects was more pronounced and long lasting in response to the combat film than to the noncombat film, but type of film had no systematic effect on control subjects' responses. These findings are consistent with biological models that posit sympathoadrenal activation in response to memory-evoking cues of traumatic events in PTSD. |
