Impact of Sleep on Brain Health

One thing that the cleaning system does,

it cleans up any little amyloid or calcified

plaques that can start to build up in the front part of

the brain.

So I'm gonna quote two very famous people

that boasted on only needing five hours sleep a night.

One was Margaret Thatcher.

Now, I think those five hours of sleep a night

was not, um...

it was not the early part of the night, was it?

Her five hours probably started at about 1 or 2 o'clock in the morning.

How did she spend the last 20 years of her life?

Severe dementia, Alzheimer's. And what they have found

in Alzheimer and, uh, dementia

patients when they've done post-mortems on them, they've got

amyloid plaques built up here. Now, this is where our

reason, intellect, and judgment is.

When someone's got Alzheimer's, how's their reason, intellect, and

judgment?

Gone. Not there. And they have

discovered that it's these amyloid calcified plaques

that are inhibiting reason, intellect, and

judgment
