A traumatic brain injury (TBI) refers to damage to the brain caused by an external physical force sometimes seen with a car wreck, fall, sports-related accident, or assault. A TBI is not caused by internal factors such as a stroke or tumor, and it does not include brain damage that results from prolonged lack of oxygen. It is possible to have a TBI and never lose consciousness. Traumatic brain injury can have wide-ranging physical and psychological effects and may be accompanied by pain. Some signs or symptoms may appear immediately after the traumatic event, while others may appear days or weeks later.
