So it's a differential diagnosis.

It's a symptom.

Dementia is a symptom.

What's causing it?

Very, very complicated.

And that's another thing I want to get out is that people shouldn't despair.

We always get asked, do I have Alzheimer's or dementia?

Well, clinically, you may have a dementia.

You may not.

We do that with our tests.

Biologically, we don't know until we do your biomarkers or we look at the brain.

Right.

But we are looking at people we have followed during their lifetime and characterized their cognition.

So if you come and say, I'm a super ager, I don't like, first of all, let me say that we define super agers.

There's no such a thing as a biological super ager that came out of a

the Garden of Eden, we said, here's what a super-ager is.

A person who's 80, who takes this one memory test of 15 words and gets at least nine out of 15 words at the end of 20 minutes, remembering that, period.

Very, very narrow.

So we have self-selected these people.

It's not like, you know, we're gonna go out in the street and find all these, you know, you have to pass a screening test for us to call you a super-ager.
