Document Summary
Traumatic brain injury is injury to the brain from a traumatic force. Open brain injuries could be from a gunshot wound, or a hit to the head and results in a fracture to the skull. The extent of the injury depends on how much force was involved and what part of the brain was affected. Injuries to the lower part of the brain usually results in loss of life. Closed head injuries are traumatic injuries as well. The body is usually moving in a forward direction very quickly and then the body comes to an abrupt stop. When your head get hits abruptly the skull stops but the soft tissue in the brain keeps moving and gets damaged. There may be extensively bleeding inside the brain as a result of this type of injury. The bleeding results in pressure and loss of neural tissue. The only way to tell sometimes that there has been damage is from behavioral symptoms.
