Living near a major roadway may increase the risk of Alzheimer’s disease and other forms of dementia. Researchers followed 6.6 million Canadians for a decade and found those living within 160 feet of a major highway had a 7% greater risk for developing dementia. Study author Dr. Hong Chen adds, “Our study suggests that busy roads could be a source of environmental stressors that could give rise to the onset of dementia.”
