I appreciate your analysis. I found him just plain confusing, and couldn’t follow what seemed to me to be a word salad, ringing around some buzzwords with no logical train of thought.
And, your recommendation of a geriatric psychiatrist rather than a neurologist also makes good sense, because he seems to make up stuff to make himself look good, but that are only confabulations of how he wants it to be, not how it is.
And, he seems to expect that we will believe these fantasies.
You are exactly right. And he’s dug in, they will not be able to get him to change his mind.
