This study is testing the usefulness of two types of Brain Health & Wellness classes for Veterans with a history of concussion to improve mental health.

This is a pragmatic, randomized controlled trial of Mindfulness-based Stress Reduction (MBSR) in 120 Veterans with comorbid PTSD and chronic mTBI. Half of the participants are randomly assigned to MBSR and the other half, to a Brain Health education class, which serves as an active control group. A battery of standardized psychological and cognitive measures are administered prior to and following the class interventions to assess change in response to the intervention, with an additional 6-month follow-up assessment to test for lasting changes. The primary outcome measures include the Mayo-Portland Adaptability Inventory IV (functional outcome), PTSD Checklist (psychological outcome), and cognitive control test (cognitive outcome).

• 18-75 years old
