Results of an extensive survey have indicated that exercise, even if it's just moderate walking, can help prevent the development of Alzheimer's disease. RedOrbit.com reports that those who go on walks more often than those who don't are protected from brain shrinkage and memory.
The research focused on 300 volunteers over a period of 13 years, which showed that those who walk at least nine miles a week will experience the best results.
Four years into the study, 40 percent of those involved had developed some type of dementia or cognitive impairment, and scientists found that the effects were more significant on those who walked less or not at all.
"If regular exercise in midlife could improve brain health, thinking and memory in later life, it would be one more reason to make regular exercise in people of all ages a public health imperative," leader of the study Kirk Erickson told the news source.
According to the Centers for Disease Control, physical activity can also prevent older adults from experiencing falls, which one in three adults over the age of 65 experience.
