How long must a high school athlete wait to play again after a concussion?

Complete recovery: Return to play for a high school athlete should not be considered til all symptoms have resolved. It is important that the athlete have no symptoms during exercise as well. As the athlete heals, they will have no symptoms at rest but exertion can cause mild symptoms. If they are at this point, they should refrain from competing. If you have access to baseline neuro testing, a repeat test may help.

Depends: The effects of concussions can vary and be unpredictable. It depends on the severity of the injury. The best thing is to give your brain complete rest. The more strain you place on your brain while it is attempting to heal, the more likely it is to slow down the healing process. You should not return to your regular physical activities until your are completely symptom free and back to normal.
