Parkinson's Disease & VITILIGO Recent posts on this subject have raised some interesting questions for me in light of some observations we have made at Loma Linda University Medical Center. These being: a. 90 % of Parkinson's patients seem to have blue, green or hazel eyes as opposed to brown or dark eyes. b. We have yet to see an African-American with Parkinson's Disease Could it be that there is a relationship between the loss of the pigment neuromelanin in the substantia nigra and people with skin which lacks melanin? Or stated another way could melanin serve as a protector against Parkinson's Disease? Don Dr. Don Berns 4943 Del Monte Rd. La Canada, CA 91011 818-790-8812 <[log in to unmask]>
