Book excerpt: Sleep disorder experts discuss specific behavioral techniques, psychotherapeutic techniques and pharmacotherapy, comprehensive and integrated approaches, disorders of the sleep-wake schedule, and specific populations--the chronically ill and older adults. The field has seen rapid advances in recent years and has attained growing respectability--insomnia is now seen as something more than a manifestation of depression or simply an annoying nuisance to be extinguished with hyponotics.
