In the United States an estimated 300,000 sports-related concussions occur annually. Many of these are young athletes who are referred to the emergency department for evaluation. While there are robust clinical decision aids to clarify the need for a CT brain, the literature around concussions is a bit murkier. Recently, athletes who sustained a concussion were recommended to avoid exercise and vigorous cognitive activity until their symptoms resolved entirely. Several studies over the last several years have challenged these recommendations. Dr. William Meehan is the director for the Micheli Center for Sports Injury Prevention. We were fortunate to “pick his brain” regarding questions we are often asked by the parents of the young athlete . . . when can their child return to play? When can they return to their full course work at school?
