Subjects included 716 older men and women without dementia who were participating in the Rush Memory and Aging Project, based at Rush University Medical Center in Chicago. The majority of participants were women, and subjects volunteered to take part, so findings were not necessarily representative of the general population. That being said, just six months of increased physical activity was shown to improve memory, language, thinking and judgment problems by almost 50 per cent!
