Re: diagnosis--several sources have said that PD is NOT diagnosed by MRI,CAT, other tests, but CLINICALLY. One of these was our own neuro, who specializes in PD, another was Dr. George Paulson, head of neurology at the Parkinson Cent er of Excellence at Ohio State U., and cited as one of the"Hundred Best Doctors in the US" in a reference book by that name. So while it is *possible* she may have PD, there should be symptomatic indications, it seems. Camilla Flintermann, CG for Peter, 76/6+ in Oxford,OH
