A historical perspective on sleep disorders medicine

The recent development of sleep disorders medicine traces its origins to the increased understanding of basic human sleep physiology gained over the past 30 years. The primary tool for diagnosis and management is the long-term polygraphic recording of multiple physiologic variables (polysomnography). A "style" of practice is emerging that is multidisciplinary and often institutionally-based in sleep disorders centers. High patient and physician satisfaction in this field indicate that rapid growth will continue.
