❝ Living near a high-traffic road may cause more mental health problems than just sleep deprivation, according to Canadian researchers.
In a population-based cohort in Ontario, dementia, but not Parkinson’s disease or multiple sclerosis was more common in people who lived close to a major road than those who lived further away from the road, reported Hong Chen, MD, of Public Health Ontario…and colleagues.
❝ According to Chen, “increasing population growth and continuing urbanization globally has placed many people close to heavy traffic. With the widespread exposure to traffic and growing population with dementia, even a modest effect from near-road exposure can pose an enormous public health burden.
“Quantitatively speaking, our study estimated that 7%-11% of dementia cases in patients who live near major roads were attributable to traffic exposure alone,” he explained…
❝ In an accompanying editorial, Lilian Calderón-Garcidueñas…of the University of Montana in Missoula, and Rodolfo Villarreal-Ríos, of the Universidad del Valle de México in Mexico City, wrote that the study “opens up a crucial global health concern for millions of people.”
❝ Additionally, the researchers concluded that exposure to nitrogen dioxide and fine particulate matter was also linked to higher dementia incidence, but did not account for the full effect…
He also suggested that changes in transportation emissions and land use policies may help to prevent dementia and improve public health.
Living in healthful surroundings with reduced pollution and noise seems like a standard easy to understand for most human beings. Perhaps our populist blather-meisters really are extra-terrestrial aliens in disguise. 🙂
