A concussion is a brain injury caused by a bump or blow to the head that can change the way your brain normally works. Even what seems to be a mild bump or blow to the head can be serious. CDC developed a kit to teach parents, student athletes, and coaches how to prevent and recognize concussions. This kit includes a Fact sheet for coaches on concussion, Fact sheet for athletes on concussion, Fact sheet for parents on concussion, Clipboard with concussion facts for coaches, Magnet with concussion facts for coaches and parents, Poster with concussion facts for coaches and sports administrators, Quiz for coaches, athletes, and parents to test their concussion knowledge
