Aging Research

Longer life expectancies and a growing elderly population pose healthcare and quality of life challenges, including limited mobility, impaired cognition, and reduced autonomy. To meet the challenges of aging, SRI's research on aging studies on blood pressure and cognition in the elderly, sleep apnea in elderly twins, and more.

SRI also develops new technologies to support independent aging, so that the elderly can grow older without having to leave the home.

Current studies in the Genetic Epidemiology and Aging Research Program at SRI's Center for Health Sciences examine the effects of tobacco use across the lifetime, and the genetic and environmental causes of performance declines associated with normal aging.

Researchers use data from two longitudinal aging studies: the Western Collaborative Group Study and the National Heart, Lung, and Blood Institute Twin Study. Volunteers from SRI's Twin Research Registry™ are also recruited for studies on aging.
