Mr. Bridgeman (aka Viartis) makes some good points and in some areas is ahead of many researchers. His ideas about the importance of dopamine precursors and the complexity of the possible problems are particularly sensible. However, and IMHO, he still is focused too narrowly. The loss of olfactory function and the patterns of Lewy body formation observed by Braak still need explaining, for example. ---------------------------------------------------------------------- To sign-off Parkinsn send a message to: mailto:[log in to unmask] In the body of the message put: signoff parkinsn
