Girija,

I don't know - but Parkinson's always seems to be singled out.

Here is my personal story:

I was in the PRECEPT clinical trial for 2 years. During that time I was in an email group with about 15 other trial participants. A subset of the folks in my email group was doing very well - so well that they had no disease progression and didn't have to start "regular" pd meds. We all figured they were on the "good stuff."

As it turned out, these people were on the placebo, and as part of the larger placebo group, their group did better than the people who were taking the experimental drug.

I was in the group taking the lowest dose of the experimental drug, and my group did the worst (go figure!)
