I'd take a guess and say about 40% of all cases of ADHD are just undiagnosed/improperly treated neurological issues.

I feel this explains a considerable amount of the cases of high-functioning ADHD.

Many of these neurological issues involve dysfunction of the same catecholamines involved in ADHD, but in slightly different places, but nonetheless this similarity is what leads to many of these ADHD symptoms developing in neurological issues.
