This is an attempt to catalog Donald Trump’s apparently worsening mental condition, because I couldn’t find any other web pages doing the job.
Check out the Alzheimer’s Association list of 10 early signs and symptoms of Alzheimer’s. Note that a very common symptom of Alzheimer’s is disturbed sleep, with sufferers waking up upset and angry in the small hours. Recall that Trump’s 3am Twitter rants have become a running joke.
Again, as with the Russia stuff, I’ll leave it to others to make any definitive claims. This is just a timeline of events which may be evidence. Make up your own mind.

17 Feb 2016: Repeatedly confuses Ben Carson and Barack Obama.
21 Mar 2016: Trump offers a rambling response to questions about nuclear weapons use and ISIS:
RYAN: If you could substantially reduce the risk of harm to ground troops, would you use a battlefield nuclear weapon to take out ISIS?
TRUMP: I don’t want to use, I don’t want to start the process of nuclear. Remember the one thing that everybody has said, I’m a counterpuncher. Rubio hit me. Bush hit me. When I said low energy, he’s a low-energy individual, he hit me first. I spent, by the way he spent 18 million dollars’ worth of negative ads on me. That’s putting [MUFFLED]…
RYAN: This is about ISIS. You would not use a tactical nuclear weapon against ISIS?
TRUMP: I’ll tell you one thing, this is a very good looking group of people here. Could I just go around so I know who the hell I’m talking to?

13 Oct 2017: Trump again wanders away forgetting that he’s supposed to sign an executive order.
13 Oct 2017: Trump refers to having met with the President of the Virgin Islands. He is the President of the Virgin Islands, which are a US territory.
6 Dec 2017: Trump suffers slurred speech during a press conference.

28 Apr 2019: People on Twitter note that a symptom of frontotemporal dementia (FTD) is loss of balance and progressive supranuclear palsy (PSP), which causes recurrent falls that are often backwards. Sufferers often try to compensate for this by adopting a forward leaning stance.
STAT magazine has reviewed decades of Trump speech, and concluded that his language has become noticeably more simple and confused.
I’m no doctor, but it seems plausible to me that Trump has the early stages of dementia. In a way this would be a positive thing, because it would suggest that his constant lying and reversing himself isn’t malice or cynicism, but simply an inability to remember anything. On the other hand, the idea of a President prone to paranoia and angry outbursts isn’t comforting at all.
