Frequently Asked Questions
10. What role do environmental factors play
in the development of Parkinson's? - cont'd
There are a number of toxins that can cause parkinsonian symptoms
in humans. One such toxin is
1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, or MPTP, found in
some kinds of synthetic heroin. Viruses are another possible
environmental trigger for Parkinson's. Scientists are pursuing the
question of whether other environmental factors not yet identified
also may cause Parkinson's disease.
