Engaging in regular physical exercise, eating a Mediterranean Diet, not smoking, and drinking alcohol in moderation were all found to decrease the risk of developing Alzheimer’s and other forms of dementia in a recent study conducted in the United Kingdom. In addition, preventing and treating diabetes, high blood pressure and obesity was also found to reduce the risk. Studies suggest that exercise three to five times a week for between 30 minutes and an hour is beneficial. But while heavy drinking was linked to dementia, drinking moderate levels of alcohol was found to be beneficial. A review of academic studies and data by researchers at the University of Edinburgh revealed that more than three quarters of cognitive decline – age-related changes in brain skills including memory and speed of thinking – was accounted for by lifestyle and other environmental factors including level of education.
