Phil Tompkins has done an excellent job of gathering statistics on the number of people with Parkinson's and has in the process produced numbers which agree fairly closely with the published UK figures. My understanding of the differences between the UK-compatible figure of half a million PWPs, and the popular 1 million figure, is that it depends on how widely you spread your definition of 'PD'. I am prepared to live with both estimates: consider it this way : The inclusion of a particular 'marginal' illness in the total will be justified if the cure (when it is found) cures both the classic Parkinson's Disease, and the marginal condition. Until then, I can live with both figures. Regards, -- Brian Collins <[log in to unmask]>
