Purpose of Study 

We aim to examine the relationship bewteen cognitive function and sleep quality as a function of aging; and to determine whether sleep disruptions differ across individuals with mild cognitivie impairment, depending on stroke-status (i.e., chronic stroke survivors versus non-stroke).  These findings will be used to develop a randomized controlled trial to test interventions designed to improve sleep quality in an effort to promote cognitive function in older adults at risk for dementia.
