Study Links Traffic Pollution And Dementia
A new study involving the health records of millions of Ontarians has found a link between traffic pollution and dementia. The findings suggest the closer you live to a major highway, the more likely you are to develop dementia.
Researchers say people who lived within 50 metres of a highway or major road had a seven percent increased likelihood of developing dementia compared to those who lived more than 300 metres away.
They say air pollution from vehicles may be a factor in the development of the neurological disease.
The study, published in this week's Lancet, looked at the health records of more than 6.5-million Ontario residents between 20 and 85 years old.
