For years research has linked some pesticides and toxic chemicals with the development of Parkinson's disease. Recent research from the military base Camp Lejeune strongly suggests that one possible cause of PD is the toxic chemical trichloroethylene (TCE). The drinking water at Camp Lejeune was contaminated with high levels of TCE and perchloroethylene (PCE) for 35 years at 280 times safety standards.
In the past century, TCE (and the similar chemical PCE) has had numerous industrial, consumer, military, and medical applications. For example, it is used in dry cleaning clothes, removing paint, as a degreaser, carpet cleaner, and engine cleaner. It even was used to produce decaffeinated coffee in the past! It's still used today - much less in the US, but increasing in China.
The problem is that TCE is environmentally persistent, and contaminates soil, air, and water. Vapors from underground water and soil contamination seep out into homes, schools, and workplaces. It is known to be carcinogenic (cancer causing) and associated with numerous cancers and other health harms, including birth defects.
The neurologist Ray Dorsey (at Univ. of Rochester), who was part of a team looking at TCE and Parkinson's disease (see post), was recently interviewed about the research linking TCE and PD. One finding: there has been a major increase in Parkinson's disease in the past decades, making it the "world's fastest-growing brain disease".
What you can do: Dr. Ray Dorsey (and fellow researchers) feel that PD is preventable. (their book). He recommends that everyone, but especially all persons with Parkinson's disease, try to avoid pesticides as much as possible. For example, use a carbon filter for drinking water, eat organic foods, don't put pesticides on the lawn, etc.
Excerpts from Dr. Subramanian (Professor at UCLA) interview with Dr. Ray Dorsey, from the medical site Medscape: Is Most Parkinson's Disease Man-Made and Therefore Preventable?
Subramanian: I wanted to first highlight some of the work that has come out and gotten a large amount of media attention around Camp Lejeune and specifically trichloroethylene (TCE) as a cause of Parkinson's, and one of the environmental toxins that we talk about as something that is in pretty much everywhere. This paper came out, and you wrote a commentary in JAMA Neurology as well. Perhaps we can summarize the paper and its findings. ...continue reading "The Case For Some Toxic Chemicals Causing Parkinson’s Disease"
