Originally designed as a resource for those preparing for board certification in headache medicine, the first edition of this book became a staple in training programs across the United States and worldwide. Building on this success, the second edition of Comprehensive Review of Headache Medicine serves as a versatile text designed for both learners and experienced practitioners who treat patients with various types of head pain, namely doctors, nurses, dentists, and therapists. Dr Morris Levin serves, once again, as the editor of this multi-authored work to ensure a useful and coherent reading experience, with current information and recommendations. The second edition begins with chapters on the anatomic and physiological foundations of head pain, followed by detailed sections on diagnosing primary and secondary headache conditions. Subsequent chapters cover the treatment of headache disorders, including special populations and complementary therapies. Expert authors have focused their chapters on the practical needs of medical, dental, and other healthcare providers. Instead of exhaustive referencing, each chapter includes a list of recommended readings and self-assessment questions, totaling around 260 throughout the book. The content has been thoroughly updated to reflect recent advances in our understanding of headache medicine and covers all required information from the headache medicine board exam.
