Written by a Harvard-educated doctor who conducts clinical and scientific research in the area of sports injuries and concussive brain injuries, this book provides readers with honest and authoritative information about concussions. The book's chapters address the subject from all angles and shed light on current debates related to concussions caused by sports injuries and accidents.
