Hi to Les in Ontario, Your request on various subjects will I am sure, be answered by other list members, but one thing you mentioned, I would like to comment on. That being "choking up at a minor emotional event". I have had a tremor for two years which has been diag as PD. I have noticed that for the last few years I do what I would describe as that very thing. It may be reading or hearing about some wonderfull thing that happened to a person, or even an animal. Or just the opposite, some tradegy that has occured to someone. I have no idea if there is any connection to my being in the process of developing PD. I would be interested in anyone else has expercienced rhe same feelings. Lanier Maddux Chattanooga n ([log in to unmask])
