Koala, i agree with you. Dr Silburn is a nice fella and an excellent Dr rolled into one and well worth consulting. I've seen my share of neuros and he is I think the most knowledgeable in the country regarding PD.

A dose of levodopa if given to you and were to result in a reduction of P.D. symptoms would be a quick way and one which is often done to diagnose PD.
I've never heard of levodopa reducing the bodies ability to produce dopamine alongcamejones.
