Now from Times Square, here's what you need to know.

So there's a study out that's taking a look at how sleep quality when we're younger can have an impact on our brain as we age.

Correct, and you said the key words to Marko when we're younger so this study

really about quality and quantity let me take you through it because I think

you'll find the result as interesting as I did, published in the journal

Neurology. They looked at people in their 30s and 40s, had them wear

wrist trackers just about six days, and then followed them up 11

years later, giving them some cognitive tests and they

analyze memory learning processing speed in this small group. What they

found is that the people in this group who had reported and noted disrupted poor sleep in their 30s and

40s were at two times greater risk for low cognitive performance. So that's

things like verbal frequency, fluency, memory, learning issues when tested 11 years down the road.

Big picture, one in three Americans do not get enough sleep every night.

I think three of us maybe sitting right here. And I will say that

the estimates are that 39 million Americans suffer from sleep apnea which can cause disrupted sleep.

So this is really about connecting the dots of what we can do midlife

to help our cognitive function later in life.

But sometimes it's other people making my sleep not so great.

Are you speaking about your little toddler or your husband?

Right.

I was keeping it generic. There you go. Well that's for another second.

Thanks Dr. Dad.
