Living in a disadvantaged neighbourhood may be linked to poorer brain health

I know science is about measuring and evaluating everything, again and again. And it's mildly interesting that it can be detected on MRI scans.

But isn't it kind of obvious that someone living in poor conditions will be worse off? Doesn't it just confirm what is already well-established in regards to physical and mental health?

> Yu said neighbourhood disadvantage should therefore be considered when designing health interventions and public policy.

But shouldn't it already?
