Today, the population in the world is older than ever before. The National Institute on Aging (NIA) at NIH supports and conducts research to better understand the aging process, as well as diseases and conditions that can occur as we grow older, such as Alzheimer’s disease and related dementias. Watch this video to learn more about NIA’s mission, history and research that has led to important scientific discoveries about healthy aging.
