Scientists have linked the risk of dementia with life from busy roads – RBC

People living near roads with heavy traffic have a higher risk of developing dementia (dementia). To such conclusion came researchers from Canada, reports Reuters.

the Study showed that people living within 50 m from roads with high traffic have the risk of dementia by an average of 7% higher. Scientists explained this by the fact that pollutants are released into the bloodstream and can cause inflammation associated with heart disease.

“This study shows that air pollutants can also through the bloodstream into the brain and lead to neurological problems,” said one of the authors of the study, the employee health Department of the province of Ontario ray Cops.

In the study, researchers analyzed the medical records of more than 6.5 million Ontarians aged 20 to 85. In the period from 2001 until 2012, dementia was identified in more than 243 thousand inhabitants of the province. Installing the closeness people live to major roads, scientists have found that as the distance from the slopes, the risk of developing dementia is reduced. Those who live at a distance from 50 to 100 m from roads, the risk of developing the disease is 4% higher than average. We live at a distance from 100 to 200 m — 2%. If a person lives more than 200 m from the road, increased risk disappears.
