Dementia rates 'higher near busy roads'

    Dementia rates 'higher near busy roads'

    Jan.5, London: People who live near major roads have higher rates of dementia, research published in the Lancet suggests.

    About 10% of dementia cases in people living within 50m of a major road could be down to traffic, the study suggests.

    The researchers, who followed nearly 2m people in Canada over 11 years, say air pollution or noisy traffic could be contributing to the brain's decline.

    Dementia experts in the UK said the findings needed further investigation but were "certainly plausible".

    Nearly 50 million people around the world have dementia.

    However, the causes of the disease, that robs people of their memories and brain power, are not understood.

    The study in the Lancet followed nearly two million people in the Canadian province of Ontario, between 2001 and 2012.

    There were 243,611 cases of dementia diagnosed during that time, but the risk was greatest in those living closest to major roads.
