Most people do not even think about whether they are cognitively impaired or not. It is only those who fear that there is a problem who may obsess about it. Seth Meyers looks at the way that Trump keeps boasting about the results of his ‘cognitive test’, a test that is not used to test how smart you are, as Trump seems to think, but to see if you are showing signs of dementia. (Note that he took this test back in 2018 and it was administered by his then White House personal physician Ronny Jackson who subsequently resigned amid allegations of misconduct and is now running for a Texas congressional seat on an ardently pro-Trump platform.)
