Totowa, NJ, Humana Press, 2004, 191 pages, $89.50 hardcover More than one third of American adults experience persistent insomnia, the second most common complaint—after pain—in the primary care setting. However, insomnia has often been ignored, trivialized, or summarily (often erroneously) attributed to underlying or preexisting psychological problems. This handbook is the first clinically oriented text dedicated to the evaluation and treatment of insomnia. Chapters cover the epidemiology, physiologic basis, and differential diagnosis of insomnia; insomnia in children and adolescents; sleep state misperception; sleep hygiene; insomnia caused by medical and neurologic disorders; insomnia associated with psychiatric disorders; primary sleep disorders; and cognitive-behavioral and drug therapies for insomnia. Each chapter is accompanied by detailed case studies, algorithms, charts, and graphs.
