Traumatic brain injury, also referred to as TBI, is a complicated injury that occurs from a sudden trauma that causes injury to the brain. TBI may result when your head suddenly hits an object or if an object pierces the skull. These injuries generally occur from falls, traffic accidents, interpersonal violence, or participation in sports. TBI is manifested by either loss of consciousness, alteration of consciousness or mental status, or focal neurological deficits, which can come and go. TBI is a leading reason behind morbidity and mortality worldwide. It remains the leading cause of death and disability among teenagers in developed countries.
