A friendly and useful article, but a bit off target when the writer cites a "seven weeks" waiting period for surgery as a problem because dopamine is "fast disappearing." Seven weeks? Is this writer engaged in a bit of hyperbole? I wonder, has anyone done a comparison of waiting times in Canada and the US not only for a PD related surgery but also for a broad based assortment of diseases? And, how about the costs to the patient? The costs to the economy? The Canadians with whom I have discussed health care say they would not exchange their system for ours. I don't know if we are, overall, superior to Canada, or they to us. Does anyone know of an objective, understandable, credible, less-than-400-page study of the two systems?
