Like many other studied effects, this is less likely to be a specific cause of ADHD and autism spectrum symptoms, and more a generator of broad brain malfunction.

The diagnostic criteria for these conditions has two parts - the underlying symptoms themselves, and a severity test that indicates whether the person with them is unable to handle the symptoms well enough to do without treatment. This is explicitly in ADHD and autism spectrum diagnostic criteria, but to a good extent is an unavoidable part of it; if someone is quite brilliant and successful but a little strange, there's no reason for them to ever seek some kind of diagnosis.

I'd be very curious to see IQ test results here, as I suspect that it is an explanatory factor.
