Combat-related flashbacks in posttraumatic stress disorder: phenomenology and similarity to panic attacks.

Combat veterans (N = 25) with posttraumatic stress disorder had flashbacks related to their combat stressors, which included major losses and exposure to danger. Certain affects, loud noises, fatigue, and personal stress tended to precipitate flashback episodes. Flashbacks began a year or more after exposure to combat in 50% of patients; 56% of patients experienced daily flashbacks. Flashback phenomenology met DSM-III criteria for panic attacks. The similarity of flashbacks to panic attacks suggests treatment trials with monoamine oxidase inhibitors or imipramine for these selected symptoms.
