Part of the "What Do I Do Now? series, Concussion uses a case-based approach to cover common and important topics in the examination, investigation, and management of acute and subacute concussion. Each chapter provides a discussion of the diagnosis, key points to remember, and selected references for further reading. The book addresses a wide range of topics that run the spectrum from acute concussion to the possibility of long-term sequelae of concussion, and is suited for physicians and sports medicine clinicians. Concussion is an engaging collection of thought-provoking cases which clinicians can utilize when they encounter difficult patients. The volume is also a self-assessment tool that tests the reader's ability to answer the question, "What do I do now?"
