mTBI

Mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) are important conditions for the Veterans Administration (VA) that frequently occur together in combat Veterans from the conflicts in Afghanistan and Iraq. In many Veterans these become chronic, raising the risk the burden of neurotrauma can worsen over time. This study will examine a new intervention called non-invasive Vagal Nerve Stimulation (nVNS) and its effects on memory and symptoms of PTSD and mTBI as well as brain and physiology in Veterans with mTBI and PTSD.
