The 3rd edition (2015) of the well received Concise Sleep Medicine Handbook continues to fulfill the goal of the previous editions in summarizing the essentials of sleep medicine to aid candidates preparing for the ABIM examinations in sleep medicine and to provide an easy reference guide for the busy clinician. Important changes found in the 3rd edition of the International Classification of Sleep Disorders (2014) are incorporated. The essentials of the latest AASM Manual for the Scoring of Sleep and Associated Events (Version 2.1,2014) are summarized as are AASM practice parameters and concensus statements from SLEEP and the Journal of Clinical Sleep Medicine. Recent advances in sleep medicine and important reviews from peer reviewed journals since the this book's last edition are included as is the Medicare policy for PAP therapy and scoring of respiratory events. Practical approaches in the management of the most common sleep problems are presented and each chapter ends with review questions. The book maintains the format of using bullet points to facilate review and highlights facts needing particular emphasis.
