I'm visiting my neuro on Tuesday (the 8th), and I want to talk to her about this subject. Someone on the list posted a message titled "Interesting reading," a little while ago, but I can't remember who. Also, I saw something on the NBC news about this, a couple weeks ago, I think. They said that it has been determined that massive doses of X-rays can get rid of the substance which keeps neurons from regenerating. It dealt with the subject of paralysis, though. I heard no mention of P.D. or any other disease. All I want to know right now is the name of this substance, so I can discuss it with the doc. Thanks, Jacob Drollinger
