Moving beyond the debate over whether and to what degree mild head injury has lasting neuropsychological sequelae, this book is predicated on the assumption that it does cause some problems in some circumstances for some people. It focuses on the practical questions of who is injured, how injuries manifest themselves, and what evaluation and treatment strategies are optimal, for families as well as patients. The distinguished authors bring to their task not only scientific expertise but extensive day-to-day clinical experience. This book will be widely welcomed as the first comprehensive overview of what we have learned from research and clinical experience about these difficult cases.
