What is traumatic brain injury?

Traumatic brain injury is a serious condition in which the brain is damaged by a sudden injury. There are many causes of traumatic brain injuries, including traffic or sport accidents, falls, or assault.

Traumatic brain injuries can occur with or without fracture of the skull. Skull fractures include open and closed fractures. Open fractures occur when the skin has been breached and the skull is broken. In closed brain fractures, the skin is not broken but the underlying skull is broken.

The brain may be pierced by an object, which may be embedded in or pass through the skull. In some cases of traumatic brain injury there may be no outer signs of damage, even though the brain itself may be bruised, swollen or bleeding. All types of traumatic brain injuries may be life threatening and cause permanent damage.

Treatment will vary substantially depending on the severity and cause of the traumatic brain injury. Surgery may be required to stabilize the injury.
