Independent scientists respond to a study that highlights a possible link between heavy traffic and dementia
Results of dementia research revealed
Dementia is more likely to strike people that live close to major roads which suggests air pollution and/or noise from traffic might be contributing factors, The Lancet suggested. The Canadian medial journal based its conclusion on a study of close to 2 million people which resided in the province of Ontario, from 2001 to 2012.
During this time frame, 243,611 residents were diagnosed with the degenerative brain condition in the studied regions. Scientists concluded that compared to living 300 metres from a major thoroughfare the risk was: 7% higher within 50 metres, 4% higher between 50 and 100 metres and 2% higher between 101 and 200 metres.
