Traumatic brain injury is the result of a blow to the head. This can
come from a fall, a vehicle crash, an assault, or shaking a baby. The brain
tissue itself may be hurt, the blood vessels can rupture and cause bleeding,
or a combination of these injuries may occur. Concussion (a temporary loss of brain function), contusion (bruising of the brain), fracture (broken
skull bones), and hematoma (blood clot) are all types
of traumatic brain injury. The June 11, 2003, issue of JAMA includes an article about use of hypothermia (lowered body temperature) in treating traumatic brain injury.
