Traumatic brain injury (TBI) is a disruption in the normal function of the brain that can be caused by a bump, blow, jolt to the head, or penetrating head injury. TBIs can range from mild, with temporary symptoms, to severe injuries resulting in long-term complications or death.

TBIs are a significant health concern and can impact cognitive, physical, emotional, and behavioral functioning. It is critical to understand the various facets of TBI to provide appropriate care and intervention.
