Ivan I have the same symptom characteristics you described. The Mayo Clinic said I don't have typical PD tremor - instead I have a jerky involuntary sort of movements,, sometimes very fine where I just feel it internaly and other times it has little or bigger involuntary movements. My Neuro got the opinion of a couple other Neuros that also looked me over and and the even plugged me into a special machine that the clinic has special to measure and define differant types of movements. I'm told it's Myoclonus and they tried to explain it to me by describing it as having thousands of tiny- teensy strokes. Thus the look - weary, one eyelid drooping / loosing t's tonemore the other side, no actual "resting" tremor. There's much more to it, but the Neuro expressed her belief that many Young-Onset PWP's may have been hit by a yet unidentified vitruas which brought this 'Parkinsonism" - but it doesn't fit into any category of identified althoughrare PD-PLUS diseases like CBCD, or PSP etc. She was trying to get support for a study in that direction.
