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 provider resources for more information.
