Such exams are not usually part of presidential physicals, but Trump requested the test, and passed with a ideal 30 out of 30 score. The 10-minute exam is created to detect mild cognitive impairment, generally in older patients.
Ahead of the exam, the White House said that tests for mental acuity would not be included.
Dr Jackson said he had "absolutely no concerns" about Mr Trump's cognitive ability.
But in a press conference this morning, Dr Jackson said the President's heart was healthy, his teeth were healthy, and he did "exceedingly well" on a hard cognitive exam. It asks a series of questions ranging from drawings of animals, which patients must name, to copying a cube, and counting backwards from seven. It is not a psychological exam.
Now, White House physician Ronny Jackson announced: "The president's overall health is excellent".
"It was interesting when I spoke to Dr. Jackson". His blood tests and other vitals were all normal.
He gets plenty of exercise on the golf course and at the White House complex, the president told Reuters on Wednesday.
During the 2016 presidential campaign, then-candidate Trump had longtime physician Dr. Harold Bornstein release a letter in which he wrote that Trump "unequivocally, will be the healthiest individual ever elected to the presidency".
"It's called genetics. I don't know".
Graham, Donald Trump's usual go-to congressional confidante for shop talk and golfing, wasn't invited over the weekend to dine at Mar-a-Lago. His mother died at 88 and his father lived to 93, though he suffered from Alzheimer's disease for about five years.
Among the healthier presidents, George W Bush used to make time for running or exercise every day, once telling Runner's World that he sometimes ran on Air Force One while travelling.
In response to speculation that the president has mental health problems, Jackson said, "In my opinion, that s just tabloid psychiatry".
"When they get to a certain range. that means he has heart disease".
It follows a three hour medical examination last week, his first since entering the White House.
"The president hasn't said he didn't use strong language, and this is an important issue", press secretary Sarah Sanders said, "He's passionate about it, he's not going to apologize for trying to fix our immigration system".
Jackson said that Trump, who weighs 108 kgs and stands 6 feet 3 inches tall, "would like to lose ..."
"He has a history of elevated cholesterol, and is now on a low dose of Crestor". Trump also takes aspirin daily for his heart, propecia for hair loss, a daily vitamin and an occasional cream for rosacea, a skin condition. "He would benefit from a diet that is lower in fat and carbohydrates, and from a routine exercise regimen".
