What's the % liklihood of a 2nd concussion after your 1st one?
Research suggests that if someone has already received one concussion, they are 1-2 times more likely to receive a second one. If they've had two concussions, then a third is 2-4 times more likely, and if they've had three concussions, then they are 3-9 times more likely to receive their fourth concussion.
