Ten to fifteen percent of adults suffer chronic insomnia and account for the largest proportion of patients seeing health care providers for sleep-related problems. Insomnia increases risk for other chronic diseases, including hypertension, diabetes, depression, and dementia. Daytime sleepiness impairs work performance and increases the risk of industrial and motor vehicle accidents. Sleep loss due to sleep-related breathing problems leads to profound sleepiness and life-threatening cardiovascular and pulmonary diseases. Sleep deprivation is known to increase risk for depression and dementia. Sleep medications themselves carry morbidity such as falls, daytime anxiety, and worsened sleep apnea. In this chapter, we review normal sleep, disorders of both sleep and wakefulness, and a logical clinical approach to these disorders.
