Parkinson's Disease based on the pill-rolling tremor, a festinant gait, muscle stiffness
Sadly - no. My father had PD (eventually died from PD complications) and, at least initially, had none of those symptoms. He discovered he had it in follow-up tests after a TIA.
He was an industrial pharmacist and spent the next 20 years putting his skills to use in PD management (especially the drug regime and timings) - he ended up doing lectures for PD specialist nurses so, hopefully, his testing (mostly on himself!) will continue to bear fruit.
Another elderly gent that I knew also had PD - in his case it was very, very mild and only progressed very slowly. As others have said - the presentation can be extremely variable and the methods used to diagnose one can't necessarily be used to diagnose another.
