Brief summary: The purpose of this study is to examine the effects of the sleep aid Lunesta (Eszopiclone), on older adults who reside in a nursing home and have poor sleep as determined by wrist actigraphy.

Detailed description: Older people living in nursing homes do not sleep very well for many reasons including pain, sleep disorders like sleep apnea (when someone briefly stops breathing during sleep) and night time urination, as well as the environmental disturbances caused by living in the nursing home, such as noise and disruptive care routines. Previous studies' attempts to improve sleep by modifying the nighttime nursing home environment have shown limited improvements in sleep.

This study will evaluate how well eszopiclone (Lunesta) works to improve sleep in nursing home residents with poor sleep. Eszopiclone is FDA approved and has been tested on older adults living in the community, but not on older adults living in nursing homes. We expect sleep to improve on the study drug, in comparison to the placebo. Based on adverse events reported in previous samples of older subjects, we expect the study drug to cause very few side effects.

We will evaluate how well eszopiclone works by measuring sleep at night and during the day. After consenting and final determination of eligibility, participants will complete a baseline phase to assess typical sleep, as well as daytime alertness and activity, thinking, memory and mood. Sleep at night and during the day will be objectively assessed with wrist actigraphs for all subjects. Approximately half will also receive polysomnographic studies to assess nighttime sleep. Subjects who sleep more than 75% of the time they are in bed will not continue in the study. Subjects will be randomized to one of two treatment groups-one will receive the active drug and then a placebo and the other will receive the placebo first and then the active drug. Following randomization, subjects will complete a brief run-in phase and then enter the treatment phase. Assessment of sleep and other measures will be repeated.
