The study is the first to show that walking improves memory, but better yet, we can protect from the ravages of dementia. The research, led by Professor Nicola T Lautenschlager, chair of Old Age Psychiatry at the University of Melbourne, is published in the September 2008 issue of the International Journal of the American Medical Association.
The researchers explored the effects of moderate exercise on memory function over a period of 18 months. The results showed that memory improved with walking, based on testing provided to the participants. Even better, the memory improvements lasted for up to twelve months.
The scientists looked at 170 people who complained of memory deficit, but had no criteria for dementia. One group maintained their normal routine, while the other engaged in a 24 week home based program of moderate exercise, aimed at walking for 50 minutes three times a week. The exercise group performed an average of 20 more minutes daily than the control group. At the end of the study, the exercise group outperformed the control group on memory tests, showing lower Clinical Dementia Rating Scores.
The authors are excited about the results of the study, titled the "Fitness for Ageing Brain Study", conducted at the University of Australia. “Unlike medication, which was found to have no significant effect on mild cognitive impairment, physical activity has the advantage of other health benefits such as preventing depression, quality of life, falls, cardiovascular function and disability, ” says Dr. Lautenschlager.
Walking is a simple approach to preventing memory loss and reducing the increasing rates of dementia as we age. Estimates show that delaying the onset of cognitive decline by 12 years would result in 9.2 million fewer cases worldwide.
Anyone caring for the elderly parents, as well as healthcare providers, should consider the importance of the study when making recommendations that can improve quality of life and provide independence in our senior years.
The incidence of dementia is expected to reach 106.2 million worldwide by 2050. The study is also of major importance to baby boomers, when considering ways to age gracefully.
Start a walking program early, and enjoy years of independence and quality of life. The sooner you get started, the better you’ll feel. Walking outdoors is also a great way to get your twenty minutes of Vitamin D from sunshine on a regular basis. Vitamin D, combined with regular walking is a sure-fire way to prevent mental decline, associated with aging.
