And studies that have

evaluated eliminating amyloid in the brain, such as the new Alzheimer's drugs, have been minimally effective because amyloid is not the full story.

Amyloid is just part of the story.

And it makes sense that if you remove amyloid,

you won't be curing someone with Alzheimer's disease.

We've now seen that in human studies.

What I have done over the years is to work on these treatable components of brain atrophy.

And one way to improve brain function is to increase blood flow and reduce cortisol levels.

Cortisol is toxic and it gets higher when you have stress and anxiety.

So one way to reduce levels of cortisol and improve the brain function is through activation of the vagus nerve.

Now you don't need a vagus nerve stimulation to reach that point.

You could do something called HRB biofeedback.

Heart rate variability biofeedback is form of biofeedback where you sit down and breathe slowly.

for 10 to 30 minutes.

You just breathe in with a count of six, hold for a count of three, and breathe out for a count of six.

When you do that, you slow down your heart rate.

You also increase the variability from beat to beat.

See, let's say your heart is beating at 60 per minute, but it's not exactly one per second.

One is 1.1 second, the other one's 0.98 second, the other one 0.97, the other one's 1.2.

There's a real variability on the time between one heartbeat to the next heartbeat.
