But in bad news for the Trump campaign Dr John Garten has identified signs of advancing Alzheimer's in Donald Trump.
To a lay person like me there's little difference between memory loss and dementia but Garten, an acknowledged expert in the field from John Hopkins universtity, explains that while Biden might mix up words Trump is displaying "Phonemic paraphasias" —the substitution of non-words for words that sound similar. That's something not normally seen until a patient enters the moderate to severe stages of Alzheimer’s.
An observation augmented by that fact that while Trump is also mixing up people, and generations, in a way that Joe Biden, currently, is not.

In something of a backhanded compliment to Trump Garten explained further
There is also a person's baseline. This is an essential tool for evaluating a person's mental decline. If you look at Trump's interviews and speeches from the 1980s for example, he may have always been a bit of a jerk, but he was articulate and polished. Now if you look at Trump there is great deterioration. By comparison, Biden has never been the most articulate person; he always had a stutter. He always made gaffes.
