To Mya Marsh-- two thoughts, forwhat they're worth. Stress DOES VERY DEFINITELY increase PDsymptoms. Also, you might want to ask his neurol- ogist who diagnosed him if, since he doesn't respond to Sinemet, it is possible he may have a variation of PD--one of the several "Parkinson's Plus" versions. One distinguishing characteristics is that these do NOT respond to the PDmeds. I hope he is seeing a neurologist who has a lot of PD patient experience, a movement disorder specialist, if available where he lives. The diagnosis can be quite tricky. Good luck-- Camilla Flintermann,CG for Peter 78/7,Oxford,OH [log in to unmask]
