Noninvasive Brain Stimulation Combined With Written Exposure Therapy for PTSD in Military Personnel With TBI

Starting soon · Not applicable · Has a placebo group

Conditions studied: Post Traumatic Stress Disorder

In brief

In this study, the investigators are evaluating whether transcranial direct current stimulation (tDCS), a brain stimulation technique, can be combined with Written Exposure Therapy (WET), a standard talk therapy for posttraumatic stress disorder (PTSD) to improve treatment response and improve symptom of traumatic brain injury (TBI). After consenting to be in the study, participants will be asked to complete a baseline assessment of your psychological and physical health that will determine whether you are able to participate in the study. Following the baseline, you will be randomly assigned to receive tDCS or a sham/placebo. Everyone will also participate in 5 weekly WET psychotherapy sessions for 5 consecutive weeks. The first appointment will be 90 minutes and the subsequent appointments will be 60 minutes. tDCS or sham/placebo will occur during the writing portion of the session. All participants will also be asked to complete 1-, 3-, and 6-month posttreatment follow-up assessments.
