The January 1997 issue of Scientific American features a very well written article, "Understanding Parkinson's Disease" by Moussa B.H. Youdim and Peter Riederer. High-quality reprints are available by calling 212-754-0550, or by fax, 212-355-0408. I recommend it highly as a very good coverage of the basic features of PD. Gaylord Rough <72-14-NY>
