Signs and symptoms of a concussion


Every concussed athlete will describe their symptoms differently and no two concussions are alike. The key to keeping our athletes safe is being able to recognize and report when a concussion is suspected. As a coach, the signs and symptoms of a concussion can be either observed or reported to you by the athlete or teammate. It is important to know that concussion symptoms will change throughout the athlete's recovery.
