Jennifer and Will-- don't know if this is pertinent for you, but in Peter's case he is sure that there were symptoms many years before his dx that were "PD precursors." He had real memory problems, depression, loss of sense of taste, constipation, and others which were documented in his medical records some 15 years before he was dxd at about age 70. The internist he used to see, who supplied copies of the records, was not surprised re: the PD--he said he wondered if P. had PD, but "didn't say anything". His dry eyes, Will, were not a problem till a few years ago, however.
