Rosemarie Scolaro Moser's new book, Ahead of the Game: The Parent's Guide to Youth Sports Concussion (University Press of New England) is just what it says it is: a practical, no-nonsense guide for parents about sport concussions.  To be sure, for someone as steeped as I am in subject of youth sports concussion, much of the book plows familiar ground. But there is also much in Moser's book that parents - even those with concussion experience - may be learning for the first time and find not only informative but perhaps surprising. It is a welcome addition to my concussion library, and I believe, should be for yours!
