HealthDay (3/5, Salamon) reports that research scheduled for presentation March 4 at the American Heart Association’s meeting suggests that “people who are fit in their 40s seem to retain more brain volume two decades later and also perform better on decision-making tests.” In fact, “the analysis of more than 1,200 participants who were tracked for more than 20 years showed that those with lower fitness levels at midlife had smaller brain volumes in their 60s – a sign of accelerated brain aging.” Researchers arrived at this conclusion after following 1,270 people who “underwent exercise treadmill testing in the 1970s,” then underwent cognitive performance testing and MRI brain scans when in their 60s.
