Bob, one of us is confused. At the Kaiser Medical Library just today I copied the first page of the article at the location you cite. Its title is: "Electrical Stimulation Of The Subthalamic Nucleus In Advanced Parkinson's Disease" by P. Limousin and several others including one of the principal developers of DBS for PD, A. Benabid. It's a good account of their long-term follow-up of 24 DBS recipients, but I must have missed the disturbing estimates of PD incidence that prompted your letter. Cheers, Joe Disease" -- J.
