My Dad has PD and is visiting me until tomorrow. He has not joined this list since he is essentially computer illiterate. He was diagnosed this past year with PD and is (tomorrow) 78 yrs old. One of his main concerns is what should he do about constipation. If it is important to know, he is taking Sinemet and Amantadine. Any suggestions on how to combat the constipation? Please email responses to the list and to me at home. I'll pass the info on. Thanks-
