Transcranial Magnetic Stimulation in Veterans With PTSD
Purpose
With this research we hope to begin to understand how rTMS can improve posttraumatic stress disorder (PTSD) symptoms. TMS improves PTSD through two interrelated mechanisms: change in brain limbic system function and change in systemic inflammatory activation. If you decide to join this study, you will receive ten rTMS treatments. All participants will undergo a 40-minute rTMS procedure with a member of the study team 10 times over 2-4 weeks. Participants will undergo fMRI scans of the head in order to help researchers better understand potential effects of rTMS on brain activity. In addition, you will be asked to give two breath and blood samples to look for general signs of inflammation.
