DOD TBI Worldwide Numbers

Service members can sustain a TBI during day-to-day activities, such as while playing sports or participating in recreational events, military training and military deployment. The majority of traumatic brain injuries sustained by members of the U.S. Armed Forces are classified as mild TBI, also known as concussion.

Most service members who sustain a mild TBI return to full duty within 10 to 14 days through rest and the progressive return to activity process, in which patients gradually return to normal activity using a standardized, staged approach. Further treatment is available if symptoms persist after the recommended rest period. Review our TBI Resources for Medical Providers page for more information about the PRA and other clinical recommendations and tools.

Those who have been diagnosed can find symptom management fact sheets, caregiver guides, and other patient-centered resources on the TBI Resources for Service Members, Patients, Families, and Caregivers page.
