      vehicle accident.

AB  - This study examined whether patients with posttraumatic stress disorder (PTSD) 
      related to motor vehicle accidents (MVAs) would show an abnormal pattern of 
      electroencephalographic (EEG) alpha asymmetries, which has been proposed for 
      particular types of anxiety. Patients with PTSD (n = 22) or subsyndromal PTSD (n 
      = 21), traumatized controls without PTSD (non-PTSD with MVA; n = 21), and healthy 
      controls without MVA (n = 23) underwent measurement of EEG activity during 
      baseline and exposure to a neutral, a positive, a negative, and an 
      accident-related picture. Differences in brain asymmetry between groups were 
      observed only during exposure to trauma-related material. PTSD and subsyndromal 
      PTSD patients showed a pattern of enhanced right anterior and posterior 
      activation, whereas non-PTSD with MVA participants showed the opposite pattern. 
      Furthermore, posterior asymmetry in nontraumatized healthy controls varied with 
      gender, with female participants showing a pattern of higher right posterior 
      activation. The results support the hypothesis that symptomatic MVA survivors are 
      characterized by a pattern of right hemisphere activation that is associated with 
      anxious arousal and symptoms of PTSD during processing of trauma-specific 
      information.
