Would like some information on the experience of others with several PD symptoms. My mother, 82 years old, PD - 5 yrs., experiences a great deal of saliva accumulation - especially at night. Although she does not drool, she is very upset with it and naturally complains of having a very dry throat. She tries to keep a lozenge or candy in her mouth during the day - but gets tired of the same tastes and sugar content. I should mention she has a full set of dentures which don't fit well because of bone loss and frequently develops sores in her mouth. Are the sores PD-related? I'd appreciate any suggestions on how to deal with this problem. Thanks much! Cathy
