Computer Use And Exercise Combo May Reduce the Odds Of Having Memory Loss

Apple iPadCombining mentally stimulating activities, such as using a computer, with moderate exercise decreases your odds of having memory loss more than computer use or exercise alone, a Mayo Clinic study shows. Included in this report is a video summary of the study results with the lead research.

Previous studies have shown that exercising your body and your mind will help your memory but the new study, published in the May 2012 issue of Mayo Clinic Proceedings, reports a synergistic interaction between computer activities and moderate exercise in “protecting” the brain function in people better than 70 years old.

Researchers utilized 926 people in Olmsted County, Minn., ages 70 to 93, who completed self-reported questionnaires on physical exercise, and computer use within one year prior of the date of interview. Moderate physical exercise was defined as brisk walking, hiking, aerobics, strength training, golfing without a golf cart, swimming, doubles tennis, yoga, martial arts, using exercise machines and weightlifting. Mentally stimulating activities included reading, crafts, computer use, playing games, playing music, group and social and artistic activities and watching less television.

“The aging of baby boomers is projected to lead to dramatic increases in the prevalence of dementia,” said study author Yonas E. Geda, M.D., MSc, a physician scientist with Mayo Clinic in Arizona.. “As frequent computer use has becoming increasingly common among all age groups, it is important to examine how it relates to aging and dementia. Our study further adds to this discussion.”


Yonas E. Geda, M.D., neuropsychiatrist at Mayo Clinic in Arizona, discusses the correlation between moderate exercise, computer use and mild cognitive impairment.

The study examined exercise, computer use, and the relationship to neurological risks such as mild cognitive impairment, Dr. Geda says. Mild cognitive impairment is the intermediate stage between normal memory loss that comes with aging and early Alzheimer’s disease. Of the study participants who did not exercise and did not use a computer, 20.1 percent were cognitively normal and 37.6 percent showed signs of mild cognitive impairment. Of the participants who both exercise and use a computer, 36 percent were cognitively normal and 18.3 percent showed signs of MCI.

Dr. Geda expects that this study will lead to more research on this topic.

The study co-authors include Ronald C. Petersen, M.D., Ph.D., and other investigators at the Mayo Clinic Study of Aging in Rochester, Minn. The study was supported by the National Institutes of Health, the Robert Wood Johnson Foundation and the Robert H. and Clarice Smith and Abigail Van Buren Alzheimer’s Disease Research Program.
