Sleep disorders in the older patient

Sleep changes dramatically with old age. Subjective and objective measures demonstrate an increase in sleep and wake disturbances with advancing age. The older person has a more fragmented sleep, sleeps less deeply, and tends to experience early morning awakenings. When older patients have sleep disorders, they often present with excessive daytime sleepiness, insomnia, or abnormal motor activity. In making the appropriate diagnosis, the role of the provider is to review the patient's medical history,psychiatric history, medications, underlying medical illnesses, and sleep-wake pattern. The aging process itself does not cause sleep problems and sleep requirements do not decrease with advanced age. The prevalence of insomnia, sleep-related breathing disorder, PLMS, and RLS increases with age and may lead to poor sleep quality. Because many sleep disorders are potentially reversible, it is the responsibility of the primary care provider to screen for these problems. A carefully planned clinical decision-making process when encountering a sleep disturbance in the older patient can greatly enhance quality of life and daytime function.
