FSIQ was a bad way of identifying the cohort. They should break it up into GAI, WMI, and PSI instead since the key indications of cognitive capacity are in GAI and the WMI and PSI just show the area of deficit. I.E. a 104 FSIQ may be the same as a 110 FSIQ for neurotypical since the WMI and PSI are probably 1/2 to 1 standard deviation below the mean for the ADHD cohort. I know several gifted students with an FSIQ of around 110, so that also introduces the issue of gifted behaviors which can also present as inattentiveness. FSIQ 110, GAI >> 130, WMI and PSI below 85. This assumes they used something like WISC IV. Also, ignoring PSI and focussing on WMI kind of misses half the issue. It all comes down to executive function loading.

What you are describing is similar to how I was diagnosed. I took the WAIS-IV and was told that I do not "technically" have an IQ since I have ADHD and the tests are not designed nor calibrated to measure intelligence in populations other than neurotypicals. Doesn't mean I cannot be given a score, just that it's not technically "accurate." I am quite dubious of IQ testing to begin with. But for the sake of adding to your comment, I had 2.5 standard deviations between some of my scores. I was significantly stronger in my VCI and PRI than my WMI and PSI.

  Yup. That's a good indicator of disability. My son is 3 SD between his VCI and his PSI. I've seen a lot of gifted kids with this kind of span. I received the same explanation when I was younger given that my scores were all over the place on the WAIS and Ravens. I've seen kids with FSIQ of 140 and a PSI in the high 80s. You should be able to take your VCI and PRI and get a composite score called your GAI, which correlates stronger with G than FSIQ when there's disability. IQ is measuring something that correlates with life outcomes. It is called G. It is not necessarily intelligence, nor does it indicate that it is a causative agent for life outcomes, only that there is a strong correlation. The old ASVABs and SATs used to correlate strongly with 'G' as well. VCI and PRI are the back of the brain, and WMI and PSI are the very front. It is the front of the brain that makes us human. It is why ADHD and other frontal brain disorders are in reality drastically life altering. People don't realize just how bad of a disability ADHD is.
