President Trump's cognitive test

A popular test with relatively high accuracy, the Montreal Cognitive Assessment (MoCA) is often used by doctors to quickly detect mild cognitive dysfunction in patients.

The MoCA takes approximately 10 minutes to complete. Patients are asked to answer simple questions about memory and mental function.

First, the patient must draw a line connecting numbers and letters in ascending order. Next, draw a clock, fill in the numbers, and then draw a cylinder to test visual architecture.

After completing the two questions above, you are tested on your naming ability by identifying three animals in the passage.

To assess memory, the doctor reads five words, one word at a time. The person being tested remembers as many as possible and then repeats them.

In the attention test, the patient hears a few numbers and then repeats them in the original order and in reverse order. The doctor then reads a series of letters and every time the patient hears the letter A, he or she must clap his or her hands.

Mathematical ability is also tested. You count back from 100, subtracting seven at a time until the doctor tells you to stop.

Next, the doctor tests your ability to repeat sentences and your verbal acuity (listing words that begin with a given letter). In the abstract thinking section, you explain what pairs of words like banana and orange have in common.

Finally, there is the ability to recall. You repeat the string of words in the memory exercise.

The average person who takes the MoCA scores around 26 out of 30. Last week, US President Donald Trump took the test and scored a perfect score. "The president is mentally sharp," said Ronny Jackson, the president's physician. "He is fit for duty."

Since taking office, US President Donald Trump has faced many questions about his mental health. Last week, a group of experts in this field even sent a letter asking his doctor to conduct a cognitive test. On January 16, at a press conference at the White House, Dr.Ronny Jackson confirmed that the US leader took the Montreal Cognitive Assessment and achieved very impressive results.

Speaking to reporters, Dr. Jackson said he did not ask Mr. Trump to do a cognitive assessment because "it was not necessary," but the president himself ordered it. "He took the initiative, so we followed."CNNquoted Dr. Jackson.

Dr. Jackson added that he does not plan to conduct additional cognitive testing on Mr. Trump because MoCA is sufficient. In addition, this is also the first timea president is cognitively tested.
