Traumatic Brain Injury

Traumatic brain injury, also known as intracranial injury, is an injury to the brain caused by an external force. It can be classified by severity, ranging from mild traumatic brain injury, or concussion, to severe traumatic brain injury, and can also be characterized by its mechanism or other features. Causes include falls, vehicle collisions, and violence; brain trauma occurs as a consequence of sudden acceleration or deceleration of the brain within the skull, or a combination of movement and sudden impact, and the injury can result in physical, cognitive, social, emotional, and behavioral symptoms, with outcomes ranging from complete recovery to permanent disability or death.
