To: Glenn Thompson From: Will Kuipers Hello Glenn, Welcome to the List. I too am interested in establishing that there may be a link between exposure to Carbon Monoxide and PD. After racking my brain as to my history of exposure to whatever it was that caused me to eventually develop PD, I have singled out CO as the likely cause. You will find more people on this list that think the same way, including someone who was rescued from a suicide attempt, using CO, who later developed PD. I would welcome an attempt to gather data on this and other chemical causes, to pin this down! Will Kuipers<[log in to unmask]>
