Janice, Thank you for your nice letter! Yes, I have my theories about Jack & Marguerite's PD. The leading contender has to do with Jack's affinity for bug killers, weed killers etc. (Disclaimer - this is entirely based upon conjecture, not any medical evidence or research!) But I figure that if, for example, wasp killer has the effect it does on the nervous systems of wasps, what does it do to humans? What do you think? Jack has the "classic" PD symptoms: right-side tremor, rigidity, some freezing, etc. Marguerite, on the other hand, has less definite symptoms. She has a shuffling gait, some freezing and rather frequent falls. There have been times we have even questioned her diagnosis, but she did respond to Sinemet, at least at first. Anyway, my "theory" follows that Marguerite has had more of a "second-hand" exposure to the chemicals, therefore not being affected as dramatically. But then, who knows? Jack spent much of his career as an engineer working on pipelines. Perhaps he was exposed to other toxins or metals? What I do know is that although it is sometimes difficult with the four of us living together, I am very grateful for this chance to get to know Clark's parents better - certainly better than I would have before we moved from Nebraska to Texas to live with them! Well, I've rambled on long enough!
