CDC defines a traumatic brain injury (TBI) as a disruption in the normal function of the brain that can be caused by a bump, blow, or jolt to the head, or penetrating head injury. Everyone is at risk for a TBI, especially children and older adults.

CDC’s research and programs work to prevent TBIs and help people recognize, respond, and recover if a TBI occurs.
