Trump has faced several questions about his mental fitness to be president.
"Thank you for all for being here", Bryant's Sanders says to the reporters.
Trump described the book as "full of lies", and described himself as "a very stable genius".
It tests attention, memory and visual skills, all of which deteriorate in people with mild cognitive impairment (MCI) or dementia. The doctor will then ask the patient to repeat another set of numbers backward.
As for his mental acuity, Trump was quick to note his doctor's pronouncement that he aced a cognitive exam, which he referenced with a dig at predecessors Obama, Bush and Bill Clinton for not doing more to curb threats from North Korea.
Identifying animals and reciting a list of words are among the type of challenges contained in the cognitive fitness test taken by US President Donald Trump.
Scores of psychiatric officials called on Dr Ronny Jackson to carry out mental health checks during the President's annual health screening after months of erratic outbursts and freaky physical gaffes - including slurred speech last month.
Dr. Ronald Petersen, an Alzheimer's expert at the prestigious Mayo Clinic, said he could not comment specifically on the president's cognitive health.
However, he did say that, in theory, a flawless score on the Montreal Cognitive Assessment does not necessarily rule out cognitive decline.
"He's eating what the chefs are cooking for him now, and they're cooking a much healthier diet for him now", Jackson said.
Mexico rejects Trump claim it's the world's 'most dangerous country'
The Mexican Foreign Ministry further disputed Trump's characterization of Mexico as the "most unsafe country in the world". Trump also says he doesn't want to see a government shutdown - and the shutdown deadline is fast approaching.
Trump, 71, is 6-foot-3 and his weight is 239 pounds, which is considered overweight by the medical community and just short of obese, Jackson said.
Trump's cholesterol of 223 is elevated and his low-density lipoprotein of 143 is borderline high.
"I guess they all realised they're going to have to leave it to a president that scored the highest on tests".
"His cardiac health is excellent", Jackson said. "It's just the way God made him", he told reporters.
In an article on CNN.com Wednesday, the network's chief medical correspondent cited the findings of Trump's coronary calcium CT scan, which examines calcium levels in the blood vessels that go to the heart that would indicate cardiovascular disease.
Trump is now taking several types of daily medication, Jackson wrote, including aspirin; Rosuvastatin to lower cholesterol; Finasteride to aid in the prevention of male pattern hair loss; Ivermectin to treat rosaccea when needed; and a multivitamin product.
The focus then shifted to what Sanders labeled "the most important news of the week" - the results from Trump's physical exam, with Sanders calling on Jackson to take the podium and provide more details. Calling Trump a "sociopath" (a diagnosis that is no longer used, by the way) and a "narcissist" are among the most common ill-informed jabs.
Regarding his physical health, he said he had dieted successfully before. The Montreal Cognitive Assessment (MoCA) was administered by physician Dr. Ronnie Jackson at the president's behest.
"This was a bit of a snapshot in time", she said.
"I think he will remain fit for duty for the remainder of this term and even the remainder of another term if he is elected", Jackson said.
