Once again, I recommend Kelsey Grammar’s fine series “Boss” where he plays a Chicago mayor diagnosed with Lewey body dementia.
I don’t think Biden has it, though. More likely he has a common form of dementia. Alzheimer’s and other forms of dementia have similar symptoms to LBD.
When Biden turns to shake hands with somebody who’s not there, I doubt he’s actually hallucinating that somebody is there, rather he’s confused about where he is and where the other people are.
I don’t think he has it either
