Could exposure to chemicals used in dry cleaning be linked to Parkinson’s disease (PD)?
New research from the Barrow Neurological Institute examined this question in a nationwide, population-based, case-control study of more than 19 million U.S. Medicare beneficiaries. Researchers found that people living closer to dry cleaners had a higher risk of developing PD, with the strongest association among those living within 500 feet.
The findings suggest that environmental exposure to trichloroethylene (TCE), a chemical historically used in dry cleaning, may be a potentially modifiable risk factor for PD.
