Facts A concussion is a traumatic brain injury (TBI) All concussions are serious Concussions can occur without loss of consciousness or memory Recognition and proper management of concussions when they first occur can prevent further injury or even death Most athletes can safely return to play after recovery, but everyone recovers at their own rate In general, the younger the athlete is, the longer the recovery U.S. annual rate of sports/recreation-related concussions: 3.8 million Copyright © 2017 by David M.
