LONDON (Reuters) - People who live near busy roads laden with heavy traffic face a higher risk of developing dementia than those living further away, according to researchers in Canada.
A study published in The Lancet medical journal found that people who lived within 50 metres (55 yards) of high-traffic roads had a 7.0 percent higher chance of developing dementia compared to those who lived more than 300 metres away from busy roadways.
