Dear Rick, And everyone else with the symptoms Rick describes..... My husband, a physical chemist, developed his PD symptoms about the age of 35 and also denied that there was a physical problem (unfortunately, so did his doctors - which didn't help matters). One of the worst symptoms he has had to cope with in the course of this disease has been emotional lability. Jamie has always been 'tough,' so dealing with tears that come easily has caused him to want to avoid social contact. There are probably many on this list who would be interested in hearing how others have dealt with this aspect of PD - my husband included. ----- Regards Mary Ann
