Sleep in the Older Adult
There are some who believe that as we age, we sleep fewer hours than younger adults. Yet most epidemiological studies have shown that older adults report sleeping about seven hours a night, well within the normal recommended range. The amount of deep sleep (slow wave sleep) does decrease with age, but this reduction begins in the third-fourth decades and stabilizes by our sixties. Nevertheless, there are changes in sleep that are connected to aging. The circadian rhythm advances, resulting in early evening sleepiness and early morning awakening which can be misinterpreted as insomnia. Sleep efficiency is reduced, likely a result of sleep disturbances which become more common with age. The sleep disturbances however, are not a result of aging per se, but rather are almost always related to medical/psychiatric problems, medications and polypharmacy or primary sleep disorders whose prevalence increases with age, such as insomnia, sleep disordered breathing, REM behavior sleep disorder, restless legs syndrome, and periodic limb movements in sleep. Treatment for these sleep disorders should be considered, regardless of age, to prevent or ameliorate some of the negative consequences of these sleep problems.
