Pesticides May Be Reason Farmers More Likely To Develop Parkinson’s Disease

An initial study in 2000 implicated exposure to pesticides as a possible risk factor in the development of Parkinson’s disease. Fourteen years later, we know even more about how these chemicals damage the brain.

Via Scientific American:

In 2000, a meta-analysis linked confirmed and presumed pesticide exposure with increased risk of Parkinson’s. Subsequent work supported this connection, including a large 2006 study that followed patients for nine years. The patients exposed to pesticides had a 70% higher incidence of Parkinson’s when the study ended; the risk was the same for exposed farmers and exposed non-farmers, hence some other farm-related factor wasn’t to blame. The study didn’t report on specific toxins, but more recent work out of The Parkinson’s Institute in Sunnyvale, CA, founded by Langston after the MPTP discovery, did. The authors took detailed occupational and exposure histories from farmers and their families. Paraquat upped Parkinson’s risk 2.5-fold.

Parkinson’s Disease Linked To Common Chemical

569px-Paralysis_agitans_(1907,_after_St._Leger)The petro-chemical industry likes to portray itself as the progenitor of our rapidly-advancing technological society, but it will come as little surprise to some that there is a price to be paid, principally to the health of our planet and our selves. Neil Bowdler reports on a new study showing a six-times greater likelihood of developing Parkinson’s disease after exposure to trichloroethylene (once used as a general anesthetic), for BBC News:

An international study has linked an industrial solvent to Parkinson’s disease.

Researchers found a six-fold increase in the risk of developing Parkinson’s in individuals exposed in the workplace to trichloroethylene (TCE).

Although many uses for TCE have been banned around the world, the chemical is still used as a degreasing agent.

The research was based on analysis of 99 pairs of twins selected from US data records.

Parkinson’s can result in limb tremors, slowed movement and speech impairment, but the exact cause of the disease is still unknown, and there is no cure.
