Computer Use and Exercise May Help Fight Memory Loss

Using a computer may protect against memory loss late in life, as long as you also make sure to exercise, a new study suggests. In the study, which included older adults, computer use and exercise reduced the risk of memory loss, whereas doing either activity alone did not.

Participants who engaged in moderate physical activity (such as brisk walking) and used a computer were 64 percent less likely to have mild cognitive impairment compared with those who did not exercise and did not use a computer.

Mild cognitive impairment is a condition in which people experience noticeable declines in their cognitive function, including memory and language problems, but are still able to perform everyday activities.

“The aging of baby boomers is projected to lead to dramatic increases in the prevalence of dementia,” said study researcher Dr. Yonas Geda, 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.”

However, the study relied on participants to remember how often they had exercised or used a computer in the past year. More studies will be needed that follow people forward in time to confirm the results.

Computers and exercise Some previous studies have found a link between exercise and a reduced risk of mild cognitive impairment (MCI), while others have linked cognitively stimulating activities, such as reading books, playing games or using a computer, and a reduced risk of mild cognitive impairment. But no studies have examined the combined effects of exercise and computer use.

Geda and his colleagues surveyed 926 people ages 70 to 93 living in Olmsted County, Minn. Participants were asked whether they had engaged in moderate physical activity, such as brisk walking, hiking, aerobics, strength training, yoga or weight lifting, in the past year, and how frequently they participated in the activities. They were also asked about the extent of their computer use.

Participants were examined by a physician to diagnose MCI.

Of the 205 study participants who did not exercise and did not use a computer, 41 (20 percent) showed signs of MCI. Of the 314 who both exercised and used a computer, 20 (6 percent) showed signs of MCI, the study found.

People who either used a computer or exercised experienced some protection against mild cognitive impairment, compared with people who did neither activity, but that finding could have been due to chance, the study said.

The results held even after the researchers took into account factors that could affect cognitive function, such as age, sex, education level, depression and the number of calories they ate in a day.

Protecting the brain The researchers speculated that people who engage in both physical activity and computer use may be healthier, more disciplined individuals. In other words, these activities could simply be a marker for a healthy lifestyleIt’s also possible these activities benefit the brain directly. Exercise may increase production of growth factors that promote the survival of nerve cells. Computer use, and other mentally stimulating activities, may enhance connections in the brain, making it more resistant to damage, Geda said.

Because the study was conducted in one county, it’s not clear whether the results can be generalized to the population as a whole. In addition, a sedentary lifestyle caused by too much computer use may predispose people to health problems, the researchers said.

The study is published in the May issue of the journal Mayo Clinic Proceedings.

Sorry to rain on the parade. The study cited as an “observational study” not a “random controlled trial.” An observational study can show correlations, but it is totally worthless to prove anything. In other words, “correlation is not causation.” Most people don’t know the difference between the two types of studies. Moreover, most people don’t know enough about statistical methods to be able to interpret properly any statistics generated in the course of a study. The bottom line is: from the start, it is fallacious reasoning to try to draw causative conclusions from an observational study. Unfortunately, this happens most of the time; quite often with journalists. On the other hand, an observational study is valuable because it can be a source of hypotheses. These hypotheses can then be scientifically tested for validity in a controlled environment. This is an environment in which a large enough number of participants are… Read more »

I will be 82 in August and my husband is 81– We do a crossword puzzle and a sudoku puzzle every morning…Then go outside to garden, mow the lawn, feed the birds, for the next three hours…After lunch, anothr trip outside, weather permitting, more pulling weeds, hoeing etc in the garden or outside work another 2,3, or 4 hours every day. After the evening meal, usually update all the news on our computers until bedtime. AND we have lived a happy, healthy 2l years of retirement. Plus, we have always had a pet DOG–one of the family since our children have grown up and left us independent… GREAT LIFE!

Solving puzzles has been proven to keep one alert as one ages as several studies have shown. While I extensively use my computer, as does my wife, my use is mostly confined to business or news, I challenge myself with the puzzles you refer to (at least 6 a day). My wife challenges herself with various computer games that I hae no time for because I think the computer is a tool, not a toy. Regardless, we respect each others interests and have a harmonious relationship that extends to vigorous discussions about politics, current events, and sports,

She’s a Mets fan while I favor the Rays. Their matchup this week may be a little contentious but stimulating, nonetheless!

I also need a location and drnviig experience in years to give you this info.It also matters if you have the Integra LS, Type R, etc and if it has Remote Alarm. These are all questions they ask when getting an insurance quote. They even ask if you have a B or better average in school and give discounts for that.I am 22, perfect record, been drnviig since I was 16, B average student, with an insurance rate from Philadelphia(Lots of break in’s and vandalism and traffic accidents), it costs me between $60-100 per month for full coverage and $40-80 for liability depending on the insurance carrier.So you could be looking at similar prices. Good Luck.

My dad was way ahead of his time. He told me, “Son, every day do at least one thing physical and one thing mental.”

I would tend to agree with the findings of this study. As the old saying goes “Use it or lose it” Like everything else in life, there has to be a balance between the two and this takes discipline. If a person is not careful, they will find themselves spending way too much time on the computer. I found myself doing that, so I force myself to get away from the computer and move about, go outside, tinker around in my tool shed, things of that nature. This is in addition to exercise, which for me is a good long walk.
