The CDC has recently put together an online training course "Heads Up: Concussion in Youth Sports". The course is a free, online resource available to coaches, parents, and others helping to keep athletes safe from concussion. It features interviews with leading experts, dynamic graphics and interactive exercises, and compelling storytelling to help you recognize a concussion and know how to respond if you think that your athlete might have a concussion.
