Buying Time: Improving Sleep to Promote Cognitive Function in Older Adults

The purpose of this study is to investigate whether a comprehensive group education combined with a lifestyle "activation" program that includes (a) sleep hygiene course, (b) physical activity promotion, and (c) bright light therapy, can improve both sleep quality and cognitive function among 96 community-dwelling older adults.

About this study

96 community-dwelling older adults with sleep complaints will be randomized into either a 6-month life style and sleep activation intervention program or a waitlist control group (participants in this group will be offered an abbreviated version of the program upon completion of the 6 month study). There are 3 measurement sessions to measure cognition, sleep, and physical activity at the onset of the study, the midway (3 month) point, and completion (at 6 months).
