Dear Boyd Highfield: I had the same problem and found that it disappeared or was alleviated when my dosage was reduced. I am on Ropinerol but I suspect the same may be true with the other drugs. I had been on 7mg times 3 and, because I thought more of anything was better, I requested an increase to 8 times 3 to eliminate any symptoms whatsoever of PD. Bad news. I finally recognized my blurry memory and blurry ability to express thoughts and my overall fuzzy existence and was reduced to 7 again. Those problems disappeared as far as I am concerned, but those who always considered me to be a rather "fuzzy thinker" still do. Clearly, they don't know what in the hell they are talking about. good luck to you. Jake PettifogJS
