Baltimore Longitudinal Study of Aging (BLSA) is an ongoing
study of how biology and behavior change as people get
older. A longitudinal study is a type of research
study in which the same group of people is studied and
tested at intervals over a long period of time.
The BLSA began in 1958 as a small project
involving a few men, but it now includes more than 1,100 men
and women who undergo testing. Every two years, participants
return to the National Institute of Aging's Gerontology Research
Center in Baltimore, Maryland, to undergo two-and-a-half days
of tests to assess attention, problem solving, memory, personality,
and other behaviors. The BLSA is the longest running study
of human aging. Its many findings have influenced medical
practice, changed our view on aging, and influenced the directions
of aging research.
