Brain Injury (also called Traumatic Brain Injury, or TBI) is the result of a blow, jolt, or penetrating injury to the head, which results in damage to the brain and/or surrounding tissue. The severity of a Brain Injury can vary greatly, and so can its effects. While a mild Brain Injury may simply result in headaches or fatigue, a severe Brain Injury may induce a coma, a vegetatitive state, or brain death. The location of the damage to the brain (cerebellum, cerebral hemispheres, or brain stem) is a significant factor in determining the severity of its effects. Transportation accidents are a major cause of Brain Injury, and many could be prevented by common sense safety measures (seat-belts, helmets, etc). Traumatic Brain Injury is a widespread problem responsible for a considerable spectrum of disabilities. Many of those injured may be eligible for monetary compensation.
