Could living near a busy road, increase your risk of dementia?
A new study suggests people who live near high-traffic roadways could have a higher risk of dementia than those who live farther away.
The study, published in this week's Lancet, found that Ontario residents who lived within 50 metres of a highway or major road had a seven per cent increased likelihood of developing dementia, compared to those who lived more than 300 metres away.
Researchers suggest that air pollution from vehicles may be a factor in the development of the neurological disease.
The study, led by scientists at Public Health Ontario and the Institute for Clinical Evaluative Sciences, examined health records for more than 6.5 million Ontarians aged 20 to 85.
