It remains unclear whether doctors performed any mental acuity, cognitive or neurological tests during the president’s physical exam. Questions about his mental health intensified this month after the publication of a book in which his closest advisers are said to have questioned his mental abilities.

It is also unclear whether Mr. Trump had tests common for men of his age, such as a treadmill stress test to detect heart problems.

In December 2015, as a presidential candidate, Mr. Trump posted on Twitter that his medical report would “show perfection.” About a week later, his personal physician released a four-paragraph letter saying that the candidate was in perfect health.

“If elected, Mr. Trump, I can state unequivocally, will be the healthiest individual ever elected to the presidency,” the physician, Dr. Harold N. Bornstein of Lenox Hill Hospital in Manhattan, concluded in the letter.
