Re: Clordane--this is powerful stuff! Before it was banned, it was used to termite-proof a house we were just moving out of. The fumes were so bad, and I was apparently allergic to them, that I went to our newhouse and slept there for a feew nights, while Peter (who now has the PD) stayed in the oldplace, as he was_apparently_not bothered by them. This was in about 1964, and he was Dxed in 1989--but had had many symptoms which now seem to have been precursors of PD for some 15 yrs. earlier (at least) He also used toxic chemicals in the garden, but can't recall which ones. Ironic, if the allergy and swollen nose kept me safe, and it should turn out that clordane was actually some sort of"trigger"for PD....I wonder if someday the researchers will discover WHY one person gets ONE type of PD, say with much tremor , while another gets the type with little or no tremor, but bradykinesia and rigidity(and maybe also cognitive losses)--are there different triggers/genetic predispositions for different versions???
