A comprehensive summary of sport-related concussion for parents, coaches, and athletes that considers the physics behind the injury, identifies what can be done to reduce the risk of its occurrence, and describes how to respond to a suspected concussion.Concussion injury among athletes continues to be a subject of great concern. Increasing attention and research is focusing on the most vulnerable of athletes-children. What strategies can be taken to best protect young athletes in sports from grammar school football leagues to high school hockey and soccer teams from concussion? How do we treat youngsters who suffer head injuries in sports? What are the ethical considerations in allowing children to play such sports, given the risks to still-developing brains? In this updated and expanded guide, William Meehan, MD, explains simply and clearly how coaches, parents, and others who work with young athletes can recognize concussion; best help children and youths recover from concussion injuries; and take steps to become proactive to prevent concussion. Readers will learn what causes a sport-related concussion; what happens to brain cells during a concussion; and why concussion, which in the past was dismissed as a trivial injury, is taken so much more seriously now. The book explains how to decrease the risk of concussion; addresses the potential for cumulative effects from multiple concussions, including chronic traumatic encephalopathy; and discusses the ethical dimensions of deciding whether an athlete with multiple concussions should continue to participate in high-risk sports.
