What blows me away about this study is that the Predominantly Inattentive children were the most likely to fail at school. Would it not seem more likely that if you suffered for hyperactivity, impulsiveness AND inattentiveness, as kids with ADHD combined type do, that you would be the subtype most likely to fail in school?
Do the findings of this study imply that being hyperactive and impulsive somehow gives you an advantage when it comes to school performance? Is this advantage because kids with ADHD-I are just ignored? Is this disadvantage related to the fact that the lack of attention in ADHD-I is different? Could it be that the inattentiveness in the combined type of ADHD is related to the fact that you can't attend because you are running at the mouth and running on foot and jumping into this and that and that the inattentiveness of ADHD-I is more deep seeded?
I have been thinking a lot about attention. Is inattention the same as being distracted? I think that people with ADHD-C and ADHD-HI are often distracted by their activities while people with ADHD-I are off in their own world and the word 'distracted' does not really capture what is happening to their attention.
Robert Eme, Ph.D. an ADHD researcher has described the inattentiveness of ADHD-I like this; "In ADHD-PI, the distractibility is external in that there is a failure to inhibit or block out irrelevant external stimuli." He describes the distractibility in Sluggish Cognitive Tempo (SCT) and internal and says this about the inattentiveness in SCT; "In SCT, the distractibility is internal as the mind drifts from thought to thought rather than focusing on the task."
I find Dr. Eme's insight fascinating but I would describe the inattentiveness of ADHD-C as external and the inattentiveness of ADHD-I and SCT as internal. I think that Dr Eme has described a difference in inattentiveness between two groups of people with ADHD which researchers must study as it appears, from this study, that perhaps this ‘internal’ type of inattention is more severely impairing, when it comes to learning, than the ‘external’ type of inattention.
I would love to have your comments regarding what you make of the notion of ‘internal’ vs. ‘external’ attention. Please leave a comment and let me know your thoughts.

CONCLUSIONS: The children with ADHD-C or ADHD-HI have higher incidences of comorbidities with ODD and TD than those with ADHD-I who the learning difficulties and the imbalance between VIQ and PIQ are more severe.
