General Discussion

He's a malignant narcissist, and always has been. He's going to get worse as time goes on and things no longer go his way, as he loses what few good looks he might have had, as he looks in a mirror and sees that ugly old man instead of the guy he once was. While things go south in the polls and he sees his support shrinking, he will become more and more angry and abusive. It's always been about power over others and money, and that's what it will remain.

I'm no expert at all, but that's my opinion and I'm sticking to it until I'm proven wrong. He may be getting some sort of treatments, but it's most likely related to his physical (not mental) problems. Any guy with the crap lifestyle he's had who is in his late 70s is going to have all sorts of medical issues that need to be treated.
