Living close to major roads linked to small increase in dementia risk (Abstract, the Lancet, Jan.4, 2017)

And here: Living near major traffic linked to higher risk of dementia (Public Health Ontario, Jan. 4, 2017)
Today we review a study with over 6.5 million people living in Ontario that examined the impact of living near high traffic roadways and the incidence of dementia, the first time such a study has been conducted in Canada. Results indicate a 7 percent higher risk for those who live within 50m (half a city block)compared to those who live more than 200 m from these roadways who have no higher risk. The specific pollutants found responsible include PM2.5 and NO2. Interesting that other neurological disorders such as Parkinson’s disease or multiple sclerosis were found to not have a higher risk.
