Hi Kathie, As a new subscriber (and somewhat of a 'newbie' as well), I read your message this morning with great interest. My particular situation is that I've recently become involved with a friend who has had PD for about 3 or 4 years. I am reading everything I can get my hands on in order to better understand him and his condition which appears so far to be fairly 'mild'. He is slightly stooped and has limited use of one arm. He is of course on quite a lot of medication which as you probably know causes him some unpleasant side effects. All in all tho' his spirits are high and he is a delight to be with. (I don't know if perhaps he suffers psychologically/physically more than he lets on when he's alone???) What I would like to ask you tho' at this time is at what age is someone considered 'Young Onset'? Thank you in advance for your help and any insight you can give me regarding above personal information. Ciao, H. spence
