Hi, Nancy, For now I'm in the category of Parkinson Plus Disease/Syndrome. Atypical PD would be another term though it hasn't been used much with me. I have some of the symptoms of PD; meds don't work very well, and I have been informed that my brain stem is not the brain stem of a PDer. To date Shy Drager has been scratched. As for the others- PSP, CBGD, MSA's-OPCA, SND-I don't fit any of the profiles at this time. Alzheimer's has also been scratched. I hope this clarifies some of/any of your queries. I, too, am in the dark-working my way toward the light. E May we all walk in the headdress of the sun 10:50 PM 9/16/2000 -0400, you wrote: >hi edith. >can u explain what u mean by PD+ ??Parkinsons disease plus, atypical PD, >multiple system atrophy?? shy drager? or SND? or opca? > >thanks:) >nancy > >
