children's brains were organised around hubs,
like an efficient
traffic system or
social network.
Those who had well-connected brain hubs
had either very specific cognitive difficulties,
such as poor listening skills,
or had no cognitive difficulties at all.
By contrast, those with poorly connected hubs
had widespread and severe cognitive problems.

This work suggests, he adds, that interventions should be less reliant on diagnostic labels.
"It's better to look at their
areas of cognitive difficulties and
how these can be supported,
for example using specific interventions to improve
listening skills or
language competencies,
or at interventions that
would be good for the whole class,
like how to reduce working memory demands
during learning." (???)
The findings also may explain why drugs treatments have not been effective for developmental disorders, the researchers say.
Drugs tend to target
specific types of nerve cells
but would have little impact on
a hub-based organisation.
