Well, okay. Wendy, there's more here. Scientists are pretty sure now there's a lot more going on.

I talked about this with Philip Shaw. He's a professor of developmental psychiatry at the King's Maudsley Partnership.

The British don't talk like that, but yes.

Yeah, but my point still stands. So there are other things going on in the brain that could help explain ADHD. And Philip and I talked about some of his favorite explanations.

So the first one has to do with the default mode network. Have you heard of this?

So if your mind is drifting, the default mode network is activated. We can see this in a brain scanner. But if you start thinking about something, like you start making dinner plans in your head or thinking like, oh, I better sit down and do my taxes next week or whatever, other areas of the brain light up. And in response, the default mode network kind of simmers down.

But what we see in people with ADHD, when researchers have gotten them into these scanners, is that the daydreaming network doesn't always simmer down when they're thinking about something else. It might kind of intrude.

There's another explanation that has to do with another network in the brain. Okay. So basically there are these pathways where different parts of the brain talk to one another.
