President Donald Trump (1946) is 71 years old. Everyone experiences at least some degree of cognitive and motor decline over time, and almost 10 percent of people over 65 now have dementia.
Trump exhibits some worrisome symptoms that fall into three main categories: problems with language and executive function; problems with social cognition and behaviour; and problems with memory, attention and concentration. They raise concern for a neurocognitive disease process or cognitive decline, which results in dementia.
So, when Trump went in to have his a annual presidential physical exam at Walter Reed National Military Medical Center, he was also given a test to see if he is plagued by early signs of dementia. He came out with 'no issues whatsoever' with his mental ability. He got a perfect score on a 'gold-standard dementia test'. That standard is the Montreal Cognitive Assessment (MOCA).
The MOCA test is a 10-minute routine screening test and, unless the patient is indeed displaying signs of dementia or Alzheimer’s disease, is incredibly basic. In other words: Trump passed a test designed for patients that have advanced stages of dementia.
