Study Guide to Sleep Medicine is a question-and-answer companion that allows you to evaluate your mastery of the subject matter as you progress through Textbook of Sleep and Circadian Medicine. The Study Guide is made up of approximately 290 questions divided across nine chapters that correspond to sections in the Textbook and a bonus chapter of nearly 60 questions from across the entire Textbook. Questions are followed by an Answers and Explanations guide that references relevant text (including the corresponding chapter) in the Textbook to allow quick access to needed information. Each answer is accompanied by a discussion that not only addresses the correct response but also explains why other responses are not correct.

The Study Guide's companion, the Textbook of Sleep and Circadian Medicine is designed primarily for psychiatrists, psychologists, psychiatry residents, and other trainees but is broad enough to serve as an indispensable reference for clinicians in any medical specialty. 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).
