Transport noise linked to increased risk of dementia, study finds | Dementia | The Guardian
Large survey involving two million adults found links between road and rail traffic and Alzheimer’s in particular
Exposure to noise from road traffic and railways is associated with an increased risk of dementia, according to the largest study of its kind.
Research has consistently linked transport noise to health conditions including heart disease, diabetes and obesity, but studies on transport noise and dementia were scarce and small, and findings inconsistent.
Now an “impressive” study involving two million adults, conducted over more than a decade, has concluded that people living in areas with transport noise face a higher risk of dementia, especially Alzheimer’s disease. The findings were published in the BMJ.
