Makes sense to me. >Wendy Tebay In my case my PD symptoms started about 3-4 months after suffering a liver dysfunction caused by taking the drug NIZORAL. I agree with Wendy that the researchers need to look at the whole picture, not just the dopamine producing thingies in our brains. There was some research posted on Parkinsn in the past that people with PD were found to be more likely to be low in some liver enzymes. Margaret Mates
