I don’t think that’s what happened, Parkinson’s is bad, but it’s not dementia.
We dont know what happened but sharon revealed their discussions years ago about assisted suicide when facing dementia. I could see Ozzy wanting to be taken out when facing Parkinsons which is yet another hopeless situation.
Ozzy was in decent shape a few weeks ago. But who knows? Maybe we’ll learn more later. Or not.
Parkinson’s with Lewe bodies is a form of dementia.
