Joe, Apologies for jumping in here, but I am curious. Is this loss of smell due to the common medications used by those with PD, inherent in the disease process, or what? Since loss of smell seems to go hand in hand with taste, have you noticed that also? I reference the medications, since some have that side effect.(not necessarily for PD) Anosmia (loss of smell) has been discussed on another listserv I am on, and someone mentioned that zinc deficiency is associated with this. They also mentioned the Monell Institute in Pennsylvania, or Dr. Alan Hirsch of the Chicago Smell and Taste Treatment & Research Center, Chicago 312-938-1047. Perhaps they know something in regards to the incidence of loss of smell in the general public vs. those with Parkinson's.
