The third test should be viewed with caution. Someone who already has dementia is quite likely to be unable to remember the sentence they've been told to repeat.
As I recall, this is one of the tests in the MMSE, and it's one that my Dad fails, because his short-term memory is so bad that the sentence is forgotten between it being said and his starting to say it.
He usually manages some of it, but there's nearly always a key word missing, or round the wrong way!
So it's important to establish what is, for the person, "normal" as opposed to "abnormal" symptoms.
