Bill, I discovered I had mitral valve prolapse over 20 yrs ago when I had cancer and saw a program which linked it to anxiety attacks which I developed after chemo. My oncologist thought MVP was the cause. I have never heard of it linked with PD which I have now, except there was an article I read somewhere that MVP developed in the heart at same time sympathetic nervous sytem developed in utero. Maybe one of the docs on this List can clarify or correct this claim. It doesn't help much, though, does it?
