Jackie Gilman: I wrote the following message on APDA BB in l992. You might find it interesting: From time to time I find myself in a spirited discussion with a frustrated physicist (my husband, a lawyer) regarding the cause of idiopatic parkinsons. We have negated all the usual postulations as follows: Herbicides: People had PD before herbicides existed. Pestcides: Same. Toxins from pulp and paper mills: Same. Well water: People who live in cities don't drink well water. Radon: Mostly in closed basements in granite rock areas. So where does that leave us? NEUTRINOS. They are particles found everywhere. They come from stars. They can penetrate anything - even a piece of lead 90 million miles thick. Someone is born with a genetic glitch and maybe Neutrinos love this particular glitch and move in and start their dirty work - hence parkinsons syndrome. Fix the genetic glitch - Cure PD.
