Ray Copes, chief of environmental and occupational health at Public Health Ontario, and a co-author of the Lancet paper, said that those living in cities should consider walking along side streets, jogging in parks and planning cycle routes along quieter roads where possible. “The real implications are not for individual choice, but at the societal and policy level,” he said, adding that air pollution should be factored into urban planning and building design to reduce exposure.

More cycle paths, more open space, more public transport...........makes sense for lots of other reasons as well.

Correlation doesn't necessarily mean causation. Maybe demented people live near heavy traffic. The rest of us have sense enough to move away.

1) Ice cream sale peak in the summer.

2) Shark attack peak in the summer

1. Sea swimming peaks in the Summer

2. Shark attacks peak in the Summer

The study doesn't claim that 'living close to heavy traffic' causes dementia, it claims to show an increased risk of dementia for those who live close to heavy traffic.
