A common chemical that is used in correction fluid, paint removers, gun cleaners, aerosol cleaning products, and dry cleaning may be the key culprit behind the dramatic increase in Parkinson’s disease (PD), researchers say.

An international team of researchers reviewed previous research and cited data that suggest the chemical trichloroethylene (TCE) is associated with as much as a 500% increased risk for Parkinson’s disease (PD).

Lead investigator Ray Dorsey, MD, professor of neurology, University of Rochester, New York, called PD “the world’s fastest-growing brain disease,” and told Medscape Medical News that it “may be largely preventable.”

“Countless people have died over generations from cancer and other disease linked to TCE [and] Parkinson’s may be the latest,” he said. “Banning these chemicals, containing contaminated sites, and protecting homes, schools, and buildings at risk may all create a world where Parkinson’s is increasingly rare, not common.”

Invisible, Ubiquitous

TCE was first synthesized in a lab in 1864, with commercial production beginning in 1920, the researchers note.

“Because of its unique properties, TCE has had countless industrial, commercial, military, and medical applications,” including producing refrigerants, cleaning electronics, […]
