Trump took the Montreal Cognitive Assessment test. It's a standard test used to diagnose dementia. Anyone with fully functioning cognitive skills will score 100%. Even you.
How did you do on it?
Not so!
"Scores on the MoCA range from zero to 30, with a score of 26 and higher generally considered normal. In the initial study data establishing the MoCA, normal controls had an average score of 27.4, compared with 22.1 in people with Mild Cognitive Impairment (MCI) and 16.2 in people with Alzheimer's disease."
