Psychophysiology in PTSD

Post-traumatic stress disorder (PTSD) is a complex psychopathology and therefore current therapies are not effective for all people. Recent literature consistently finds that there are differences in physiological reactivity to cues among trauma survivors exhibiting PTSD. Studies have found that many individuals with PTSD have an elevated physiological response to trauma cues when compared to those individuals without PTSD. In contrast a sub group of trauma exposed individuals is characterised by an almost opposite psychophysiological response profile. This study is a critical review of the literature related to individual differences in physiological reactivity. Understanding of the individual differences in the physiological response may prove useful for determining treatment response and predictors of PTSD.
