Interesting question. There seem to be different forms of this stupid disorder. My former gp told me he thought I had essential tremor or a reaction to other medications and sent me to the neuro just to be sure. I later learned he wrote to the neuro and stated that he believed I had PD and needed it confirmed. The neuro said that a tremor alone was not enough to diagnose PD, but after testing my muscles he said I had the "cogwheeling" of rigidity as well as tremor. On the other hand I know a lady who swears she has PD and won't go to the doctor. Several close family members were diagnosed with PD and she is sure she has it. However, after watching her and talking with her I think she has essential tremor, not PD. Who really knows, before the autopsy?? don't forget how to laugh (and do it often) Marling McReynolds [log in to unmask]
