Donald Trump has passed his mental test. This may come as either a relief or a shock.

The results of the president’s physical exam came out this week. This is normally not a big deal — when Obama and Bush got their reports, it was barely a yawn. But on Tuesday White House physician Ronny Jackson had to answer questions from the media for almost an hour.

There was a little curiosity about how anybody who eats so many cheeseburgers could be in good health. (“Genes.”) Skeptics pointed out that the report’s enthusiastic descriptions of the president’s tiptop condition seemed inconsistent with some of the statistics on his weight, cholesterol and plaque buildup in the arteries. If the doctor had simply said “good for an overweight 71-year-old guy,” everybody probably could have nodded and moved forward.

But the big news was the mental test. Trump took something called the Montreal Cognitive Assessment and got a perfect score. Not perhaps the highest bar possible, unless you were concerned about whether he can identify pictures of animals and draw hands on a clock. But the test can be useful if there is, for some reason, concern that the subject is suffering from … um, dementia.

Jackson told reporters that he has talked with Trump many times over the past year and found him “very sharp.” This is hardly surprising. When the doctor has a conversation with the president, the subject is probably always Donald Trump, a topic upon which our current chief executive is always able to focus like a laser.
