What is the Montreal Cognitive Assessment test?

US President Donald Trump passed a test for signs of dementia and is in overall excellent health, but needs to shed weight by cutting calories, fats and carbohydrates and starting a daily exercise routine, the White House physician said on Tuesday.

The Montreal Cognitive Assessment, which identifies light impairment or the onset of Alzheimer's disease, was designed by neurologist Ziad Nasreddine in the 1990s.

President Donald Trump's physical exam results give an insight into his medical health and wellness for the first time in his presidency. "There is no indication whatsoever that he has any cognitive issues.he is very articulate when he speaks to me".

Since becoming President, Trump has continued making similar claims, offering that he could score higher on an IQ test than Secretary of State Rex Tillerson and claiming earlier this month that he is a "genius".

Some hoped Trump's Friday's medical evaluation would include a cognitive or psychiatric assessment of the 71-year-old president. "A quick way to figure out Trump is not in excellent health is to look at him".

The President is mentally very sharp and very intact. Trump has been seen out on the golf course, and the guidelines do say that "some activity is better than none", but if his doctor has any say in the matter, Trump will be exercising more.

Capt. Jeffrey Kuhlman conducted Barack Obama's first physical as president.

That conversation has continued into Wednesday, thanks in large part to armchair physicians suggesting Jackson lied about Trump's height and/or weight - the term "girther" has quickly taken hold - and CNN's Sanjay Gupta even diagnosing Trump with heart disease, which Jackson disputed Tuesday.

Calls for him to reveal his weight more transparently are being led by Guardians of the Galaxy director James Gunn, whose offered to cough up USD$100,000 (A$140,000) to Mr Trump's favourite charity if he complies.

But the physician said Trump's cardiac health was excellent, noting the president had undergone an exercise stress test, and said he consulted cardiologists about Trump's coronary calcium score.

Several former members of Obama's White House staff echoed that praise of Jackson.

Trump's body mass index, or BMI, of 29.9 puts him in the category of being overweight for his height.

Trump's blood pressure was 122 over 74, and his total cholesterol was 223, which is higher than recommended. Jackson also said that, at the president's request, he performed a cognitive test, and that he had "absolutely no concern about his cognitive ability or neurological function".

Once he is up, Trump spends most of his morning in the Yellow Oval Room on the second floor of the White House residence, with his Twitter-enabled cellphone in one hand and the White House landline in the other.

Dr. Nasreddine was quick to point out that the test doesn't assess personality, mental illness or "judgement problems", even though he found it "reassuring" that Trump managed a flawless score.
