TBICoE Research Studies

In 2010, the Defense and Veterans Brain Injury Center, also known as the Traumatic Brain Injury Center of Excellence, launched the Caregiver and Family Member Study. This 15-Year Longitudinal TBI Study, led by TBICoE researchers at the National Intrepid Center of Excellence in Bethesda, Maryland is a congressionally mandated study that examines the effects of TBI incurred by service members. The specific focus of the study is on those who served in Operation Iraqi Freedom or Operation Enduring Freedom, and how those effects impact family members.

The TBICoE Caregiver and Family Member Study is ongoing and currently recruiting caregivers of service members and veterans with TBI and PTSD (TBI and PTSD caregivers), and parents and spouses who are not caregiving (non-caregiver military family members). Read the descriptions below to discover how you can best support the study.

Caring for Military Families

Currently the study is recruiting a couple different groups of people: TBI Caregivers, PTSD Caregivers, and Non-Caregiving Military Family Members.
