A new study suggests that female who exercise at a young age, particularly in their teen years, could actually lower their risk of dementia at the age of 65, according to CBC News.
The study was published on Wednesday in the July issue of the Journal of the American Geriatrics Society and was conducted by the Heart and Stroke Foundation Centre for Stroke Recovery at Sunnybrook Health Sciences Centre in Toronto. It's believed to be the first study to examine physical activity at several ages in relation to late-life cognitive activity
“If we want to optimally prevent dementia, it's important to start physical activity as early in life as possible,” said head researcher Laura Middleton. More are starting to recognize physical activity as one of the most promising means to prevent cognitive impairment and dementia. And what this study adds is that it's not only important in mid and late life — that we really have to start as early as possible.”
Research scientists are attempting to make a direct link between exercise and dementia in order to understand how brain activity actually works.
Business Week reports that the study was conducted among 9,300 women who were over the age of 65 in the United States and were asked about their exercise habits before the ages of 18, 30, 50 and in late life.
The study only looked at women and it is unsure if men seem be affected or benefit the same way.
