Could living near busy roads increase dementia risk?

A new study by British medical journal, The Lancet, has concluded that living near major roads could lead to a higher chance of developing dementia.
The research studied six million adults in Ontario, Canada between 2001 and 2012. Those living less than 50m from a busy road had a 7% higher incidence of dementia, whilst there was no higher risk reported for people living over 200m away from a major road.
Pollution has previously been linked to the development of Alzheimer’s disease but this study has strengthened that claim.
The study was led by Hong Chen from Public Health Ontario, who said: “Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia.
“Increasing population growth and urbanisation has placed many people close to heavy traffic, and with widespread exposure to traffic and growing rates of dementia, even a modest effect from near-road exposure could pose a large public health burden.”
