Barbara, Dennis Greene has a couple of letters to his friend and to his doctor that are available on Dennis' home page.They, along with the post from Dennis wife about six weeks ago and Bob Howard's post yesterday say it all. I can't remember Dennis' home page address, but I am sure he will post it to you if you ask him. Good luck with your talk. I am giving one on PD and depression in December, and although it is to PD patients and caregivers, I am feeling the same apprehension. If it were to physicians, I'd be scared spitless. Good luck, Barbara Smith, CG/Ken/69/16
