Solvent exposure may increase Parkinson's risk

Occupational exposure to certain solvents may increase the risk of Parkinson's disease, according to new study.

Researchers discovered that trichloroethylene (TCE) and perchloroethylene (PERC) are significantly linked to the developments of Parkinson's in a study of twin's occupational history.

The discovery may possibly account for the significant number of cases where a gene mutation for the disease is unable to be found.

Samuel Golden, lead researcher on the study, stated: "The potential importance is great, since both solvents persist in the environment and are commonly used.

"Parkinson's was sixfold more common is twins exposed to TCE, and ninefold more common in twins exposed to TCE or PERC."

Environmental factors have long been suspected to contribute to Parkinson's disease.

Some studies have found that working in specific occupations - such as agriculture, education, health care, welding and mining - may increase risk.

This study will prove vital is developing important prevention and treatment pathways for Parkinson's disease.
