With this first edition of Migraine and Other Headache Disorders, we celebrate the remarkable progress in the art and science of headache during the last decade. With 32 chapters by 54 leaders in the field, the book provides health care professionals with practical approaches to patient care and reviews the scientific foundations of headache. We emphasize migraine because of its high prevalence, enormous burden, and the increasing availability of effective management strategies. At the same time, we provide broad coverage of all the primary headache disorders. Finally, although not focusing on specific subtypes of secondary headaches, we discuss strategies for diagnosing and excluding the ominous causes of headache,.
