US President Donald Trump has faced mockery online after boasting about his performance on the Montreal Cognitive Assessment (MoCA) during a speech at the White House Small Business Summit. He claimed to have scored perfectly on the test three times, highlighting a peculiar example involving a 'squirrel' that left many listeners bewildered. Social media users reacted with laughter and disbelief, questioning the relevance of his comments. The MoCA, developed by Canadian neurologist Ziad Nasreddine, is a clinical screening tool used globally to detect cognitive impairment, including dementia. Nasreddine clarified that the test is not an intelligence measure but rather assesses normal cognitive performance. He noted that while a perfect score indicates no noticeable impairment, it does not signify exceptional cognitive ability. The average score for adults is 26 out of 30, with only about 10% of individuals in Trump's age group achieving full marks. Nasreddine emphasized that the MoCA should be conducted by trained professionals.
