I seem to remember that some one > wrote saying PD does not run in families.! There seems to be several distinct forms of PD, including different classes of familial PD. The latter are characterized by younger onset and faster progression, and the genetic anomaly if any may differ from one family cluster to another. Familial PD is rare, and of great interest to current researchers, so I suggest getting in touch with one if you can. Cheers, Joe -- J. R.
