and I seem to have stumbled upon something very interesting here: this list. I found you all as I was seeking additional info on this familial form of PD currently in the news. Would you like to read the _Science_ article on line? Here it is: http://www.sciencemag.org/science/scripts/display/full/274/5290/1197.html My mother had PD and one of her brothers had it but neither one of their parents had PD. Familial or idiopathic---that is the question. At any rate, I am 41 years old and do not have any symptoms of the disease at this point. However, I would like to learn more. For whom is this list intended? Would it be okay if I listened? By the way, I am a doctoral student at Pitt and took a neuroscience elective last year. The professor was a PD researcher. According to her, fabulous research is happening. Or was she just being overly optimistic? Teena
