Most injuries cause focal brain damage, damage confined to a small area of the brain. The focal damage is most often at the point where the head hits an object or where an object, such as a bullet, enters the brain. In addition to focal damage, closed head injuries frequently cause diffuse brain injuries or damage to several other areas of the brain.
