Good point. It may not be dementia yet, but certainly those brief “senior moments” occur which could lead to a disaster like this. Anybody in their 60s or older knows.
On the Mini-Mental State Exam (MMSE), a score of 23 or lower (out of 30) supports a Dx of dementia. You might be surprised how many people over 60 fail to get a passing score. I seem to recall that Trump got a perfect score of 30 a few years ago.
