Last week I posted an inquiry to the list, describing my experience with ether as a child; namely a peculiar sensitivity to ether, alcohol, or similar fumes which persisted for several years afterward. The point was to see if this acute childhood exposure had a connection with PD which appeared many decades later. Here are the results: There was a total of 4 responses. One reported mild casual exposure to ether and other solvents in the course of lab work (not relevant). One reports nausea on traversing a streetcar tunnel (containing ozone?) which still occurs after more than 50 years. One reported ether anesthesia some 40 years earlier, but no persistent aftereffect. One reported distress during the anesthesia 40 years ago, but does not mention any persistent aftereffect. Since the list represents about 800 people with PD, this response seems to indicate that ether anesthesia in childhood, followed by persistent aftereffects, is not a significant etiologic factor.
