Harley got me to thinking about how I would slice-and-dice the PD pie. It is not a monolith, but what IS it then?
We differ on symptom sets, speed of degeneration, present state, body systems impacted, and more I'm sure.
Maybe a matrix of some sort with disease features across the top and the impact upon quality of life down the side? In fact, make QOL the feature reflected at any given time? Does that make sense?
At least I see why they don't want to discuss it.
