have they really aged or is the average adult's brain today just damaged by isolation?

They haven't ruled out other possibilities, but they found a link that suggest it's possible. More studies are needed.

Extreme stress is already associated with cerebral cortex thinning, but just that alone doesn't match the previous projections and studies.

I can believe overall that group of kids (generation?) got damaged in some way, some more than others due to the age/grade and the loss of interactions that help children grow socially. Maybe because girls are more social at those ages that boys? I don't know if there's anything to support that and it's just some stereotype of how grade school girls are.

Girls are also more likely to get forced into chores and caring for siblings.

It's a pretty common thing in many cultures. Even among less conservative people gender biases are common.
