techfun89 writes "A recent study has shown that among older adults, participants who used a computer and did moderate physical activity such as brisk walking were 64% less likely to have mild cognitive impairment (MCI).
In this study computer use and physical activity reduced the risk of memory loss, but just doing one activity or the other alone did not.
Dr. Yonas Geda, a physician scientist with Mayo Clinic in Arizona and his team surveyed 926 people ages 70 to 93 living in Olmsted County, Minnesota.
Among those that did not exercise or use a computer: 20.1% were cognitively normal, 37.6% had signs of MCI. Those who did exercise or use a computer 36% were cognitively normal and 18.3% showed signs of MCI.
Previous studies have found a link between exercise and a reduced risk of MCI, while other studies linked stimulating activities such as reading books or using a computer with the reduced risk of MCI. Until now no studies showed the combined effects of exercise and computer use."
