Dyslexia also has an IQ component which means those with low IQ are not dyslexic even if they otherwise have the same symptoms.

Perhaps the definition needs to change?

Note the above is from the article which is focused on the UK. It could be different in other countries.

A person with IQ 100 (or whatever the mean IQ is) learning to read slower than average is different than a person with IQ 60 learning to read slower than average. You cannot completely remove the IQ component.

Their point might be that the ability to read, has a non-zero influence on how intelligence as well knowledge; both of which are what IQ tests try to measure. The two signal values are related to an unknown degree.

And it shouldn't really. Assuming dyslexia is the result of structural differences in how the brain operates and not simply that a person is behind the curve on reading ability.

If say dyslexia behind the scenes looked something like the difference between being left handed or right handed, a persons natural athletic skill (IQ) might improve their odds of throwing a good right handed pass yet regardless of athletic skill their outcomes would be better throwing left handed.

It no longer has an IQ component. (This is described in the article).

But doesn't the article make the case that both of your example children need the same treatment?

[bluGill]

Exactly but some don't get it because they miss the dyslexic diagnosis even though the same treatment would help if they could get it.
