Trump scored a ideal 30/30 on the test, according to Jackson, with 'no indication that [Trump] has cognitive issues'.
"He's very sharp. He's very articulate when he speaks to me", said Jackson, who works in close proximity to the president. He chose the Montreal Cognitive Assessment (MoCA) - a widely validated tool that is commonly used to screen for cognitive dysfunction, such as that seen among dementia patients. It is not a psychological exam.
Aides to President Trump said Saturday they are willing to negotiate with Democrats on the fate of an immigration program for young people brought to the United States as children, but only after Congress votes to resume government funding and the shutdown.
At 6 feet 3 inches tall and 239 pounds, by medical measurements, the president is considered overweight and almost obese.
Trump, 71, is 6'3, weighs 108 kg and has normal cardiac health, Jackson said. The president has a fasting blood glucose of 89, which is normal, and no sign of diabetes.
Lee said the screening test Jackson gave Trump "gives the public a false sense of reassurance".
"I'm totally unaware of this ever being done before", Jackson said Tuesday when asked whether such a test had ever been given to a president as part of his routine exam.
"It is called genetics". "What can I tell you?"
Trump has experienced several recent episodes in which he appeared to slur his words, adding to concerns about his health. His mother died at 88 and his father lived to 93, though he suffered from Alzheimer's disease for about five years.
The doctor also said Trump showed "excellent cardiac results. from a stress test" performed on the president last week.

The test did not assess his psychiatric fitness and his doctor said he didn't undergo a psychiatric evaluation. She read a letter written by Richard Tubb, a former physician to the president who trained Jackson and vouched for his integrity.
It was during his time in Iraq that Jackson was chosen as a White House physician and returned to the U.S. in 2006.
Most of the comparisons being made are professional athletes, so it stands to reason that Trump could in fact weight 239 pounds but be made up of considerably more fat than those he's being placed next to, who are made up of more muscle (which is denser than fat). He also has a total cholesterol of 223, which is higher than recommended, and is taking medication to address that, Jackson said.
"We're talking about a 70-plus-year-old man who is obese and doesn't exercise". (It forms the starting point of To Kill the President, the thriller written by my alter ego Sam Bourne.) But a fantasy it remains. "I get more exercise than people think".
Just to be safe, Jackson and an ear, nose and throat specialist ran some extra tests and found nothing amiss.
