This book presents necessary information and data for people working with concussion recovery or experiencing a concussion, especially of a sports-related nature. There is currently no defined body of knowledge presented to practitioners, a lacuna this book serves to fill. While medical attention is often needed at the initial stage of treatment, the most important parts of ongoing treatment are behavioural, specifically managing and monitoring the patient and engaging them in active rehabilitation strategies. The competencies described here address multiple constituencies, from medical personnel to patients. The book is designed to direct the reader to appropriate sections in a straightforward manner supported by evidence and research. Its core focus is on schools in the US, where the majority of sports-related concussion occur and are managed. However, the knowledge competencies detailed here are broad enough to provide a solid education in concussions, and what to do about them, across various environments.
