Document Number: 10971Sports-Related Concussions in Youth: Improving the Science, Changing the Culture - Not enough is known about youth concussions, concludes a committee studying the topic and they recommend many directions for future research. First, not a lot is known about the overall incidence of sports-related concussions in youth so they want to see a national surveillance system. Next, they recommend research on the molecular and functional changes in the brain following injury and whether that varies by gender. Controlled, longitudinal, large-scale studies should be conducted on the effects of repetitive head impacts over a lifetime. And, in a different direction, find out whether rules and standards for safe play affect incidence. Other rich possibilities for exploration include design of more effective safety equipment, and how to change the culture. (Institute of Medicine, National Academies, October 2013)...
