Researchers following nearly 2 million Canadians in Ontario over 11 years have discovered that living close to busy roads appears to be associated with a higher incidence of dementia.
It is suggested that possibly 10% of dementia cases amongst people living within 50 metres of a major road could be caused by traffic pollution, although the exact cause is as yet unknown. More research is required.
No such association was discovered between residential proximity to a major roadway and the incidence of Parkinson’s Disease or multiple sclerosis.
