First, I would like to welcome all the new faces around here. This place is to valuable to let die and new blood is needed on an ongoing basis to replace all those who have been cured.

Curem asks a very good question and I'll give it my shot.
Generally speaking, PD is slow in worsening. Years. If you are seeing "progression" the first question is "Why?" In particular, be sure you don't have a hidden infection such as a urinary tract or periodontal one. An infected big toe can trigger inflammation in the brain and send PD sympoms through the roof. Next is stress of any sort. Again, the effect is way out of proportion. Finally, any new meds or life changes coincide with the problem?

As for meds, despite the curses that I heap upon sinemet, it has a couple of things going for it. It works. And it has been around long enough that we know more about it.
