Loud traffic noise is associated with an increased risk of dementia, this is the conclusion reached by researchers from Denmark.

Constant exposure to car noises outside the window or to passing trains was linked to an increased risk of dementia in the largest study on this topic.

Scientists have previously linked traffic noise to health conditions, including cardiovascular disease, diabetes and obesity. But the relationship between car noise and dementia has not been studied in depth, and results have been conflicting.

And now the journal BMJ has published the results of a large-scale study of two million adults. Observations continued for more than 10 years.

It turns out that people who live in areas with very high levels of road or rail noise have a higher risk of developing various forms of dementia, especially Alzheimer’s disease.

The study authors noted a link between long-term exposure to car and train noise in homes and the risk of dementia in people over the age of 60. Observations in Denmark lasted from 2004 to 2017, and noise levels were assessed for each residential address.

The researchers also looked at other potential factors associated with the potential risk of dementia. It was found that out of 8,475 cases of dementia, 1,216 cases may be related to traffic noise. At the same time, 963 patients developed dementia due to traffic noise, and 253 – from railroad traffic noise.
