youA group of researchers from George Washington University, in the United States, who followed 649,605 people for nearly a decade, with an average age of 61, suggested that the risk of Alzheimer’s is 33 % lower for those who practice physical exercise.
The participants were divided into five groups based on their cardiorespiratory condition. The scale varies depending on the fitness level of the participants.
Scientists found that the least fit group had a 13% lower risk of Alzheimer’s disease than those who were sedentary. The intermediate group had 20% less chance of developing the disease, the following 26% less and, among the most physically prepared, the risk was 33%.
The work has not yet been published, but will be presented in April, at the annual meeting of the American Academy of Neurology, reveals the newspaper The Washington Post.
Alzheimer’s disease, remember, is the most common form of dementia. It is a neurodegenerative disease that causes progressive memory loss and cognitive decline, language impairment and even difficulty performing tasks such as paying bills and managing money.
In turn, dementia is a generic term used to designate a set of diseases characterized by cognitive alterations that can be associated with memory loss, language alterations and disorientation in time or space. For the most part, there is no cure, nor is there a definitive way to prevent dementia.
It is recalled that the World Health Organization estimates that there are 47.5 million people with dementia worldwide, a number that could reach 75.6 million in 2030 and almost triple in 2050, to reach 135, 5000000. Alzheimer’s disease accounts for approximately 60-70% of all dementia cases.
