Epigenetic differences may help to distinguish between PTSD cases and trauma-exposed controls. Here, we describe the results of the largest DNA methylation meta-analysis of PTSD to date. Ten cohorts, military and civilian, contribute blood-derived DNA methylation data from 1,896 PTSD cases and trauma-exposed controls. Four CpG sites within the arylhydrocarbon receptor repressor (AHRR) associate with PTSD after adjustment for multiple comparisons, with lower DNA methylation in PTSD cases relative to controls.

Posttraumatic stress disorder (PTSD) brings with it diagnostic symptoms that can be debilitating and persist for years. Left untreated, PTSD can have far‐reaching and damaging consequences for the individual, families, communities, and society at large. Although early detection and intervention are recognized as key to the effective treatment of PTSD, many individuals who suffer from PTSD do not seek essential health services. The aim of the present study was to identify the barriers and facilitators to help‐seeking for individuals with PTSD, based on existing literature.

This study focuses on forced migration and interstate violence during international crises, as a major security concern with salient implications for international relations stability.

Background: Veterans with posttraumatic stress disorder (PTSD) tend to benefit less from evidence-based treatments than other PTSD populations. A novel virtual reality and motion-assisted exposure therapy, called 3MDR, provides treatment in an immersive, personalized and activating context.
