## Abstract

Disturbed sleep with night wandering has been identified as one of the most
common symptoms leading to the institutionalization of the elderly, yet
little is known of the etiology of this disorder.  It may be related to
excessive awakenings.  Fragmented sleep at night and daytime napping are
major problems for nursing home residents.  Daytime sleepiness may be
caused by nighttime fragmentation, by understimulation in the environment,
by desynchronization of circadian rhythm related to inadequate
illumination, or by a combination of two or more of these conditions.  We
propose to analyze 24-hour sleep patterns and illumination exposure of
nursing home patients.  Our specific aims are to 1) describe the 24-hour
sleep patterns of nursing home patients using both EEG and actigraphic
recordings, and cross-validate these methodologies; 2) characterize the
associations between low illumination exposure and sleep fragmentation
among nursing home patients; and 3) evaluate the effects of 2 interventions
(activity therapy and phototherapy) designed to improve sleep patterns
among nursing home patients.  Each subject will be assigned to one of four
groups:  increased daytime stimulation and activity, bright light exposure
in the evening (control group).  Each group will have one week baseline,
2 week intervention, and one week post intervention follow-up.  Data
collected will describe the 24-hour sleep patterns, the sleep fragmentation
and the illumination exposure of nursing home patients.  The intervention
trials will help determine whether the sleep fragmentation seen in the
nursing home patients can be reduced and sleep consolidated by these
approaches.  The results will both help us understand the causes of sleep
fragmentation and suggest practical treatment options.
