Step-by-step explanation:
When an injury is caused by impact alone, it is generally recorded as a traumatic brain injury (TBI). TBIs can range from mild concussions to severe brain damage. An example of a mild TBI is a concussion, which is a bruise on the surface of the brain that can cause temporary symptoms like headache and confusion. More severe TBIs can result from falls, car accidents, violence, or sports injuries. Head injuries are a major cause of death and disability, with around 30% of injury-related deaths in the United States being attributed to head injuries.
