Effect of the Gulf War on reactivation of adverse combat-related memories in Vietnam veterans.

Symptoms of combat related posttraumatic stress disorder (PTSD) have been reported extensively in Vietnam veterans. A few of these studies have reported situations in which PTSD has been reactivated in veterans with a history of PTSD. The present study reports the effects of media coverage of the Gulf War on a community sample of New Zealand Vietnam veterans. Levels of PTSD, distress, and well-being were assessed before and after the outbreak of hostilities. Most veterans closely followed the media presentation of the war and reported revived memories of Vietnam. Increased memories of Vietnam were associated with higher levels of PTSD and distress. It is suggested that veterans have heightened susceptibility to combat related stimuli because of their previous combat experience and that these stimuli can reactivate PTSD symptoms and distress. Implications of this finding for other groups in the community who harbour residual PTSD effects are discussed.
