Prolonged Exposure to Road Traffic Noise May Increase Risk of Parkinson’s Disease, New Study Suggests
A new study published in JAMA Neurology suggests a potential link between prolonged exposure to road traffic noise and an increased risk of Parkinson's disease. Researchers analyzed data from over 3 million Danish participants and found that higher decibel levels at home facades correlated with a higher incidence of the condition.
Why it matters
This research identifies environmental noise as a potential novel risk factor for neurodegenerative diseases, which could influence future urban planning and public health policies.
