>> You all remember back in the 50's or early 60's there was a public service commercial about : "Mental Retardation strikes every 8 seconds" or something like that! My question is --Has anyone ever figured how often PD strikes? Let's figure it for the world now--not just the U.S.!!!<< If there are 50,000 new PD cases in the US each year that works out to roughly one new case every 10 minutes. As for the world? . . . I guess that's why we need a worldwide registry. Pass the Udall Bill in 96. Ken Aidekman
