In a country where the vitality of the president tends to serve as a proxy-in for credibility as a leader, President Donald J. Trump — now in his second term and the oldest president to hold office in U.S. history — is again making cognitive health the focal point of the nation's dialogue. Speaking on board Air Force One headed to West Palm Beach, the 78-year-old commander-in-chief made a public proclamation that he had "got every answer right" on a cognitive test administered during his annual check-up at Walter Reed Medical Center. "Good heart. Good soul. I felt I was in very good shape," said Trump, continuing that he went out of his way to take the test as a way of distinguishing himself from political rivals.But what is this mental test actually — and what does it really tell us about a sitting president's mental acuity, particularly in the tough and high-wire job of Commander-in-Chief?The president addressed openly to journalists on board during the trip to his home in West Palm Beach, Florida, assertively declaring, "I got every answer right." This comment has once again sparked public curiosity regarding the nature and importance of cognitive testing, particularly among aging political figures."I’m in very good shape — good heart, good soul, very good soul," President Trump told the White House press pool, emphasizing his physical and mental wellness. Not only did he point out the good results of his physical, but he also used the opportunity to differentiate himself from his political peers by mentioning that he took a cognitive test voluntarily — something he says his predecessors, former President Joe Biden and Vice President Kamala Harris, had declined to do.This is not the first time President Trump has boasted about his cognitive abilities. In his last term, he made similar claims, even reciting memorable parts of the test like the now-famous phrase- "Man, Woman, Person, Camera, TV."Former US President Donald Trump has been declared "fully fit" to serve as Commander-in-Chief, according to his latest physical examination report released by the White House on Sunday. The announcement comes at a time when the health of political leaders is under increased public scrutiny, especially in the United States.The report holds particular significance as Trump remains the oldest individual ever elected to the presidency. One of the key highlights of the medical update is the noticeable reduction in his weight. Trump now weighs 224 pounds, down from 244 pounds during his previous physical in 2020. This 20-pound weight loss has also improved his Body Mass Index (BMI), lowering it from 30.5- which placed him in the "obese" category- to 28.0, categorizing him as "overweight."According to his physician, this progress can be attributed to a more active and health-conscious lifestyle. The updated health report not only reflects improvements in Trump’s physical condition but also reinforces the broader national conversation around wellness and fitness in American political leadership.What Is the Cognitive Test Trump Took?The test in question is the Montreal Cognitive Assessment (MoCA), a standardized screening tool developed in 1996 by neurologist Dr. Ziad Nasreddine. It’s widely used to detect mild cognitive impairment and early signs of Alzheimer's disease. Despite its simplicity for cognitively healthy individuals, the test is a powerful tool in neurological diagnostics.MoCA tests several areas of brain function such as memory, attention, language, visuospatial abilities, and executive functions. It takes about 10 minutes and is commonly utilized by neurologists and primary care physicians to screen for cognitive impairments in persons aged 65 years and older.President Trump claimed that he got every question correct — and for a cognitively healthy person, that is what is expected. But what is the MoCA, and are its last questions as hard as Trump claims?1. Visuospatial and Executive Function TasksThe test starts with a series of drawing exercises that involve:Drawing a clock indicating a particular time, e.g., 10 past 11.Copying a three-dimensional cube.These exercises assess spatial knowledge, attention, and planning abilities — tasks that can decline with age or neurological deterioration.2. Identification and NamingThese are illustrated animals — often a lion, camel, and rhinoceros — and participants are requested to identify them. This task appears straightforward but can be sensitive to problems with recall of language or semantic memory.3. Delayed Recall and MemoryOne of the more difficult sections of the test is when subjects are required to recall a series of five unrelated words. Later in the test, they are required to recall these same words without cues. This delayed recall section often uncovers early memory lapses.4. Attention and Language RepetitionIn the following section, items involve the repetition of strings of numbers forward and backward and simple subtraction items (e.g., subtract 7 from 100 consecutively). This assesses working memory and attention.5. Verbal Fluency and AbstractionHere, the subjects are required to say as many words as possible beginning with the letter "F" within 60 seconds. Subsequently, they have to describe similarities of two things — for example, how a train and a bicycle are similar (both are means of transport).6. OrientationThe last section of the test tests an individual's sense of time and place — requesting that the subject give the present date, day of the week, month, year, and place. How Difficult Is It, Really?When asked about the difficulty of the test, Trump said, "I'll bet you couldn't even answer the last five questions. They get very hard." While certain sections, such as delayed recall and abstraction, may be challenging for people with early indicators of cognitive impairment, experts explain that the test is not intended to be excessively difficult for non-impaired individuals."The MoCA is not a test of intelligence," explains Dr. Sarah Williams, a Johns Hopkins Medicine neurologist. "It's intended to screen for very subtle indicators of cognitive decline. If you are cognitively normal, it will be very easy." Cognitive Testing and Presidential TransparencyTrump's insistence on taking cognitive testing is less about boasting rights — it is also a sign of larger public anxieties surrounding aging leaders and their cognitive abilities. With both leading presidential candidates now over their late 70s and early 80s, mental sharpness issues have become an overarching theme in American politics.Trump’s repeated willingness to undergo and publicize the results of cognitive testing could be interpreted as a strategic move to address those concerns head-on. “The American people want a mentally sharp president,” he said. “I think I’ve proven that.”
