The next brain we got looked like the brain of somebody who had a dementia disease.

because of the number of Alzheimer's changes in their brain, but they didn't, they were super.

So how can, you know, there's, there's clearly isn't just one way to become a super ager.

There are several ways.

And one of them is you don't make the plaques and tangles for reasons I don't know.

And the second is you make them, but you're immune to them.

And we do not understand why that happens.

Correct.

Right.

And when you say Alzheimer's patient, so Alzheimer's is one cause of dementia.

And so for us, when we say Alzheimer's, we mean we have looked at your brain, you have a

We've seen you in the clinic, you have a dementia, and now we have biomarkers and your biomarkers are positive for Alzheimer's.

Those people have Alzheimer's.

Other people who have cognitive loss, even dementia, we wouldn't call them Alzheimer's because they don't have the Alzheimer's causing it.

It's kind of like, I always give my patients the analogy, you have a sore throat, okay?

Why do you have a sore throat?

You have COVID.

You ate a hot pizza.

You talk too much.

You have strep.
