| Abstract: | Electroencephalogram (EEG) changes in response to trauma and non-traumarelated odors were examined in five Vietnam veterans with a DSM-III-R diagnosis of Post-traumatic Stress Disorder (PTSD) and in five Vietnam veterans with adjustment-related problems (non-PTSD). Period analysis of the EEG indicated that the odors differentially affected the PTSD group's theta and alpha activity compared to the non-PTSD group. The greatest EEG and self-report odor and PTSD effects were found in response to a trauma odor which simulated burning flesh. These findings have important implications in the detection of veterans who attempt to feign deliberately the psychophysiological response pattern associated with PTSD. |
