The National Heart, Lung, and Blood Institute of the National Institutes of Health (NIH) estimates that 50–70 million Americans have sleep disorders, and nearly 1 in 3 people do not regularly get the recommended amount of uninterrupted sleep. Yet funding for sleep research—and the number of young investigators pursuing careers in the field—have not kept pace with the magnitude of the problem. That's where the Textbook of Sleep and Circadian Medicine comes in. Designed primarily for psychiatrists, psychologists, psychiatry residents, and other trainees, it is also broad enough to serve as an indispensable reference for clinicians across all medical specialties. The volume demonstrates how common sleep disorders, such as insomnia, sleep-related breathing disorders, and circadian rhythm sleep-wake disorders, are classified across diagnostic systems such as DSM and ICD as well as the International Classification of Sleep Disorders (ICSD). This textbook distinguishes itself in several key ways: • It is truly international in scope, with contributors from around the world and coverage of diagnostic tools and treatments used across different countries. • Most chapters were drafted by trainees and early-career faculty in collaboration with senior clinicians and researchers—an approach designed to address the needs of early-career professionals. • Although comprehensive, it remains deliberately concise, emphasizing essential information and serving as a practical, easy-to-use reference. With key takeaways and recommended reading lists in each chapter, the Textbook of Sleep and Circadian Medicine equips readers to provide comprehensive, knowledgeable care to the patients they serve.
