Walking can have a positive effect on memory problems, new research suggests.
People aged over 50 who go walking for over two-and-a-half hours a week can see significant improvements in memory problems, according to a study published in the Journal of the American Medical Association.
The study of 170 people who had reported memory problems found that participants who were in the exercise group performed better in cognitive tests than the people who were in the control group.
Professor Nicola Lautenschlager, chair of old age psychiatry at the University of Melbourne and principal investigator, said: "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."
Writing in the Times, nutritionist Amanda Ursell recently suggested that people who carry a lot of fat around their middles could be at greater risk of dementia and Alzheimer's disease in later life.
Ms Ursell made the point that a larger waist size may be associated with an increased risk of developing a variety of health problems, including cholesterol and diabetes.
