President Donald Trump, the oldest President elected in US history at the age of 70, underwent his first presidential physical last January.

He used it as an opportunity to quiet critics who questioned both his physical health and mental acumen.

As part of last year's physical Trump requested then-White House physician Dr. Ronny Jackson to do something quite unusual. He asked him to administer a cognitive exam.

These types of exams are not a routine part of a standard physical. Jackson said it was the first time he was aware of any president taking any sort of cognitive test.

Jackson said Trump received a 30 out of 30 on the Montreal Cognitive Exam, a quick screening assessment for mild cognitive impairment and early Alzheimer's disease but not a diagnostic tool.

Whether it will be administered again this year, Jackson said, at the time, would be up to the President.
