Barb M, Do you think your pallidotomy has anything at all with the progression. The reason I ask is we have a PWP in his 40's (NOT IVAN) that has had bilateral Pallidotomy. My observation NoN-qualified of course, is that he has almost no chorea or athetosis, but he seems to posture with his arms behind his head and back, like a drug induced dystonia. I do experience a little of this on my surgically treated side (R) instead of the previously mentioned movement dyskinesias. It would seem to me if stress can accelerate the risk of progression then one could postulate that with the reduction of symptoms or side effects would generate a more positive outlook and therefor less stress and you got it less progression. Just a thought. Greg Leeman
