traumatic brain injury
noun
: an acquired brain injury caused by external force (such as a blow to the head sustained in a motor vehicle accident or fall or shrapnel or a bullet entering through the skull)
Traumatic brain injury occurs when the shock from an explosion damages neurological fibers. Soldiers may survive a blast with scarcely a cut, only to find over time that they suffer coordination and memory loss, dizziness, insomnia.—Nancy Gibbs
An unprotected fall, especially if the player is unconscious or his opponent lands on top of him, can result in severe traumatic brain injury.—Michael J. Stuart et al.
