I am the person for which you look (I think). Indeed, I was poisoned by CO about eight years ago, in a suicide attempt. However, I was in the garage for just about four hours, and if you think your mother has CO induced Parkinsonism, then she was probably under the influence of this silent killer at lower levels, for a longer period of time. I would have to say your best bet would be be to contact a woman by the name of Denise. Her husband, Kevin, suffers from P.D. due to long term exposure to CO. Their e-mail address is DedeMom123. Best wishes to you and your mother, Jacob Drollinger
