CON­CUS­SION: An inury to the brain that results in tem­po­rary loss of nor­mal brain func­tion. It is usu­ally caused by a blow to the head. Cuts or bruises may be present on the head or face, but in many cases there are no signs of trauma. Many peo­ple assume that con­cus­sions involve a loss of con­scious­ness, but that is not true. In most cases, a per­son with a con­cus­sion never losses consciousness.
