there's different types of dementia
Trump's isn't the classic one everyone thinks of, the losing your memories type
Trump's is Frontotemporal Dementia
specifically the Behavioral-variant
you just become crankier and crankier
stubboner and stubboner
more and more of an asshole, basically
until you become so much of an asshole that you literally die of being an asshole

Sorry to hear that fren.
There's a theory that dementia is a metabolic disease and you can stop or at least slow down the progression through a ketogenic diet.
But if your dad has already become extra stubborn on top of any original stubbornness, there might be little hope of convincing him.

A silver lining is that not all types of dementia are the same, this one isn't the one most people are familiar with, where their memories fade and they forget all their loved ones. That's probably the most cruel one.
This one doesn't have much to do with memory loss, at least in the early and middle stages.

And it's probably a very delicate subject to broach with an actual sufferer (if he is one).
Maybe go behind his back and have a chat with his doctor, if it's possible? You can explain that you think this is the situation, I think they'll understand and help plan out a way to bring him in, maybe even for other reasons, and to eventually have this come up 'organically' in the process of other health checks.
