Neurophysiology Markers of PTSD's Presence, Severity and Therapy Outcome

VA Office of Research and Development·observational·Posted Dec 24, 2019·Updated Nov 25, 2025

In Brief

An observational study evaluating Acceptance and Commitment Therapy to Improve Social Support for Veterans with PTSD ( ACT-SS) for PTSD. Completed, enrolled 26 participants across 1 site.

Detailed Summary

Current practice for diagnosing and managing PTSD relies primarily on subjective clinical assessments by clinicians as well as patient self-report. An independent, objective and neuro-physiology based method for directly assessing brain function is not available, but is much needed to improve diagnosis and management of PTSD. To address this critical need, the investigators propose to test a set of novel biomarkers which are based on measures of coherent activity among the regions of cerebral cortex during sleep. In preliminary studies on EEG acquired during sleep from Veterans with PTSD alone as well as other co-morbidities, the investigators have shown that the neuromarkers were highly sensitive/specific to the presence of PTSD, and highly sensitive to the severity of symptoms in PTSD group. The overall goal of this project is to further validate these novel neurophysiology marker in retrospective and prospective studies
