Posttraumatic stress disorder (PTSD) is a significant personal and societal burden. The
purpose of this study is to examine genetic, epigenetic, behavioral, and brain activity
changes related to PTSD dysfunction and recovery before and after treatment with Cognitive
Processing Therapy.

Using functional magnetic resonance imaging approaches, the present research aims to examine
the relationship between traumatic experience and the neural mechanisms of various PTSD
symptoms, and determine how this relationship changes during PTSD extinction. Also, this
proposal aims to better understand how the genetic/epigenetic profile of several genes
predicts, and perhaps changes, in response to recovery from PTSD along with its neural
correlates. This understanding will help identify individuals who will respond most optimally
to a specific empirically based PTSD treatment, Cognitive Processing Therapy, while further
connecting genetic biomarkers of risk with neural intermediate phenotypes underlying PTSD
symptomatology.This study is observational as the investigator does not assign specific
interventions to the participants of the study.
