I'm just going to say this is a personal observation. Trump's behavior is a lot like my mother's behavior leading up to us (brothers, sister, and me) having to put her in a nursing home because of advanced Vascular Dementia (the symptoms are the same as Alzheimer's, but the disease process is different.) Mother got extremely paranoid, calling my sister in the middle of the night that someone was trying to break into her house. Mother had a little dog that barked if a leaf moved in the yard. If my sister didn't hear the dog barking she knew to just tell Mother to go back to sleep. We had to put her in full-time nursing care when she reached the point that she couldn't remember how to walk. (She was bedridden for the last 5 years of her life because of the walking issue and she was out of touch with reality most of that time.) She was a teacher, a scientist, and an accomplished musician and ended up like that. I wouldn't wish that condition on anyone including President Trump. If that is his problem, he will not know it, but it will be incredibly painful for his family.
