On Tuesday, Rear Admiral Ronny L. Jackson, the lead White House doctor, reported that the President's overall health is 'excellent' and that he did 'exceedingly well' on a cognitive exam (requested by the President, presumably in response to the recent accusations that he is unfit to serve).
The cognitive exam is known as the Montreal Cognitive Assessment text (MoCA), and on the surface it seems pretty easy. But according to those who study dementia and mental deterioration, it is a valuable tool to determine mental capabilities. You can take the test for yourself:
Here's the thing - the test seems easy, because it is easy. This isn't an IQ test or the SAT. It's a test to determine basic mental functionality, such as “attention and concentration, executive functions, memory, language, visuoconstructional skills, conceptual thinking, calculations, and orientation.” You're supposed to get a 30 out of 30 - if you don't, that's the red flag for the doctor to examine your state of mind further.
