Very promising. There's a very strong history of Alzeimer's-like dementia on one side of my family. I feel as if my memory is not as good as it used to be, and I'm terrified I'll end up like my relatives.
I'm finding it harder to learn new stuff, but thus far the old stuff isn't falling out. But like you, I am also terrified of heading down that path - to the stage that I have already started thinking about obtaining a stock of pills so I can opt out as and when I am still capable.
While I'm pleased at this article, it seems to be something that will stabilise the brain in a particular state rather than reverse the process - and that relies on accurate early diagnosis, which doesn't happen as often as it should.
