Do you have any reason to think brand of deodorant and diet are strongly correlated with Parkinson's? (Especially pre-diagnosis.)

Ideal would be to check large numbers of undiagnosed people, and then see how many of those she "alerted" on developed the disease, but given the generally-low incidence of Parkinson's I suspect this approach would be impractical. Larger sample sizes than 12 would always be nice, of course.

Are you kidding? That'd be awesome if we could skip these expensive tests and diagnose Parkinson's by deodorant brand preference!
