Seniors who did as little as 15 minutes a day of modest exercise such as walking on a treadmill desk three days a week reduced their risk of developing dementia by about 30% according to recent studies.

The study, published in the Annals of Internal Medicine, suggests that even a short, brisk walk every day might ward off the disease. The study adds to a growing body of scientific research that suggests exercise is as good for the brain as it is for the body.

Daily exercise may delay the onset of Alzheimer's and reduce the number of people with the disease as well. Alzheimer's, which is increasingly common after age 60, causes memory loss, confusion and behavioral changes and affects 4.5 million Americans. This number is expected to increase 4 fold by the year 2050. This number could be greatly reduced with proper lifestyle and exercise choices such as daily walking.

Researchers at the University of Chicago found the brains in physically active mice had 50 to 80 percent less plaque than the brains of sedentary mice and the exercising mice produced significantly more of an enzyme in the brain that prevents plaque.

Dr. Ronald Petersen, director of the Alzheimer's Research Center at the Mayo Clinic offers profound advice: "Regular physical exercise is probably the best means we have of preventing Alzheimer's disease today, better than medications, better than intellectual activity, better than supplements and diet."

Incorporating walking with a TrekDesk treadmill desk into your daily life while you are paying bills, reading, watching TV or talking on the phone offers the exercise component so necessary in battling the onset of this serious disease.
