About the NIA

The National Institute on Aging (NIA) at the National Institutes of Health (NIH) leads the federal government in conducting and supporting research on aging and the health and well-being of older people. Our research ranges from the study of basic cellular changes that accompany the aging process to the examination of the biomedical, social, and behavioral aspects of growing older. Our main goal is to understand the nature of aging and the aging process, and diseases and conditions associated with growing older, in order to extend the healthy, active years of life.
