"Dad fell off the ladder and struck his head. Your son took a hard hit in the soccer game and probably has a concussion. What do you do now? [This book] will walk you through the steps of evaluating a head injury and will assist in diagnosing, managing, and recovering from a concussion. Based on the simple principle of The Four Rs: Recognize, Respond, Rest, and Reassess, [it] will empower you to support the injured and advocate for the best possible treatment and outcome, whether the injured person is you or someone you care about. Following the Four Rs will guide the injured through what they need in order to recover successfully and return to work, school, play, and other everyday activities as quickly and safely as possible." --Page 4 of cover.
