Don, You said you "have yet to see an African-American with Parkinson's disease." Well, I just want you to know that I personally know a number of African-Americans with PD. It may be that the incidence of PD is lower in the black community, and it's probably also true that there are a great many undiagnosed cases, particularly in those areas where health care services are not of the highest quality. But I can assure you that the black community has not been spared the curse of Parkinson's. Margot
