If she has Parkinson’s (& I believe she does), then the only reason she’s functioning is the drug Levodopa (L-dopa). She’s been on it long enough that now she is having side effect & it’s wearing off faster. She’s also having “freeze” spells - this is likely what happened to her at the 911 ceremony - she made it to the curb, but then was frozen. You never push/pull someone in a freeze ... when the SS went to move her, she toppled over (look how stiff back/neck & head were). She won’t be able to claim it wasn’t diagnosed, not if she’s on L-dopa. Parkinson’s is hard to diagnose - one of the ways they do it is to give someone L-dopa (challenge test) and if it improves their condition, then it’s likely Parkinson’s.

I’ve also looked at the possibility she has Parkinson’s....but without a medical report stating so we’re still just speculating.
The trouble with saying it’s Parkison’s is what she’s evidenced, that we’ve seen, could be another medical issue.
I believe possible she has ore than a few health problems...heck we already know she does.....but what happened on that curb was not pnemonia....nor fainting....something was going on clearly as she tood there and when she first attempted to take a step and could not support herself at all....I have questioned how rigged her upper body was....that alone reveals something else is happening there.
