Sleep disruption in older adults. Harmful and by no means inevitable, it should be assessed for and treated.

Insomnia is not a normal part of aging, but nighttime sleep in older adults is often disrupted, leading to excessive daytime sleepiness and other physical, psychological, and cognitive changes that affect overall health. Even so, clinicians often pay little attention to sleep in this population. The sleep of older adults tends to be less deep than that of younger people, and coexisting conditions and treatment effects can more easily disrupt sleep.
