In his physical yesterday, President Trump took the Montreal Cognitive Assessment and passed with 30 out of 30. Can't access the database so I can't see how I'd do on it. I have enrolled in the brain health registry, which is researching the subject. Took all the tests over a few days, and did a little better than I expected (mom had Alzheimers, although developing in her 80's, and dad seemed slower before his fatal strokes at 73 so I'm hyperconscious of anything which might indicate I'm following the same path). One thing they do not do is give feedback, so I don't know whether I'm below average, above average, or average for men of my age and background.
But President Trump might take a half-hour a day in the morning to, instead of watching Fox and Friends, participate in the registry. Be good for him, as lacking as he is in self-confidence.
