Different Regional Gray Matter Loss in Recent Onset PTSD and Non PTSD after a Single Prolonged Trauma Exposure

This study had quite a bit to offer when it came to understanding the implantation that PTSD has on the brain. It seem that the in people that had survived a trauma the volume of gray matter in the brain correlates negatively with the CAPS, or  Clinician-Administered PTSD Scale.

This article provides insight into which parts of the brain are associated with PTSD  and how MRI can serve to aid in study and diagnosis.
