John - I'd love to hear the results of your tests.

"Bradyphrenia" (slow thinking) is a symptom of PD; your brain does slow down just as the rest of you does. Maybe the key is just realizing that, and trying to do things at a different pace.

It's a tough one; really hard to adjust to when you've been super confident/competent and fast for your whole life! Remember - you are not losing your intelligence!

John-

I'd be reluctant to accept the inevitable. This seems to be happening awfully fast for PD. Have you done any kind of timeline analysis to see if there could be anything else at work? Don't discount the job stress either. Two jobs and you chase tornadoes for a break? I gotta shake my head and admire you all at the same time.

My latest bandwagon might be worth thinking about. Mycotoxins from mold and other fungi. Has there been any increase in dampness where you work or live?

Keep a food diary for a week and see if anything correlates. And have they ruled out little strokes?
