When I first went in to see an internist to determine the cause of my tremors he wanted to run a number of test including MRI (to eliminate poss CVA or TIA's) and a comprehensive blood test to check Thyroid, CO, (I've worked in auto repair for 20+ years) and a number of other blood levels. The dr. told me that the thyroid acting up could cause tremors and he wanted to eliminate all possibilities. All my tests came back in the "normal" range although CO was slightly elevated (not as much as a smoker tho.) My theory is that different environmental causes may trigger PD in different people. It may be possible that the dye could cause a reaction such as PD. There are people who are allergic to the iodine in the dye and have died from it. I guess that we may never know all the answers.
