Now a scientific study involving 99 pairs of identical twins, conducted by researchers from the Institute for the Study Parkinson's disease in Sunnyvale, California, found a "significant association" between exposure trichlorethylene and the development of severe neurological disease. The twins are used in studies of this kind on purpose, as it eliminates the possibility of genetic differences and allows scientists to note the impact of different lifestyles to develop the disease.
In general, the effect of increased risk of trichlorethylene Parkinson's disease sixfold.
