New research led by University of Pittsburgh psychologists has pooled data from dozens of studies to find that specific exercise helps episodic memory among those who are between 55 to 68 years. And 3 times a week for 4 months can do the trick. The scientists have found that there are greater improvements in memory among those who are age 55 to 68 years compared to those who are 69 to 85 years old — so intervening earlier is better. The team also found the greatest effects of exercise in those who hadn’t yet experienced any cognitive decline, and in studies where participants exercised consistently several times a week.
