STERLING JOHNSON: This study is about adult children
of people who have Alzheimer's disease.
We bring our participants in

We want to know who goes on to develop dementia

We want to be able to prevent this disease.
In order to do that,
we have to identify it as early as we possibly can.
We also want to know if there's a drug
or a lifestyle intervention
that will slow the rate of cognitive decline.
Ultimately, we want to prevent dementia.
So we call our study

So this person was 61 when they started with WRAP.
They're 73 now.
Ton of amyloid.
The participant doesn't report any memory problems.
There may be some opportunities here to study
what is it that makes a person
steady over time in the presence of disease.
It's very interesting seeing how some of the things
that people do every day
are actually very critical.
Do you read newspapers?
Or play games?
Puzzles, checkers?
The findings have been compelling that
the things that you do to keep your brain engaged
actually do kind of help you
push back against what one might have expected.
It will be curious to see how all of this
pans out in the WRAP sample over time.

MAN: I'm wondering if any of you can touch on any
evidence we have of the reversibility
or at least the ability to slow the onset or progression.
Let's say we have a biomarker or we identify people at risk.
What can we do if they then, as a 55-year-old,
improve those?
JOHNSON: We've seen that people who have
certain healthy lifestyle patterns...
Sleeping well,
keeping cognitively and physically fit and active,
modifiable things like hypertension, diabetes...
and it may be that if we can treat these things effectively,
that may slow the progression of Alzheimer's pathology.
This is tremendously important, because it tells us
that there may be an avenue of slowing down this disease
in midlife, or in fact, preventing it entirely.
BENDLIN: In our studies, we've seen effects on the brain
of a lot of different modifiable factors.
That said, you can do all those things right and
you might still develop dementia.

CARLSSON: What we're doing today is,
Sigrid's coming in to be evaluated for participation
in a clinical drug trial.
If she has any amyloid build-up in her brain,
then she'll be eligible to receive this medicine
that'll help clear out some of that amyloid.
And then we'll see if the medicine not only clears out
the amyloid, but more importantly,
if it helps protect her thinking abilities over time.

WOMAN: It's a good reminder... Mm-hmm.
That when you speak, not to...
move your head.
And Sigrid, I am now injecting very slowly.
And Sandy has started the scanner, so we're
starting the imaging right now.
SIGRID (voiceover): It's going to be physical evidence.
They are gonna sit down with me and they'll go over the results.
That will be very difficult.
This is one of the most important studies being done
worldwide right now for Alzheimer's prevention.
I think it's going to be a critical point in time
for us to see, if we get rid of amyloid,
does it really help prevent Alzheimer's disease?
And if we get rid of the amyloid
and it doesn't help thinking abilities,
and doesn't help people, then that's going to give us
a kickstart to go look in a different direction.
Hi! Good to see you!
Hi, good to see you. (speaks softly)
CARLSSON: These are two separate people.
So this is one single individual at one point in time.
And this another individual.
And both of these people have Alzheimer's disease.
They've had memory symptoms for probably years.
They've had amyloid build-up in the brain for probably decades.
The warmer colors... So yellow, oranges,
and especially the reds...
those are the areas where there's some amyloid build-up.
Now, these two people are both healthy older adults.
This person has some amyloid build-up, though.
You can see that there are some areas that have some red.
Some warmer colors.
But they don't have any memory problems.
And they do not have Alzheimer's disease.
So, at this point, again,
you are in this category.
