Forskningen är relativt ny, vilket betyder att många studier fortfarande pågår, men självklart finns det fler avslutade studier. Jag misstänker att din slutsats vilar på lathet under googlingen? Här är t.ex. några till

Imaging studies suggest that ADHD is typically associated with some structural abnormalities in the brain
The following structural abnormalities have been observed in children/adolescents and adults with ADHD versus healthy controls:
Lower grey matter density1-3
White matter abnormalities4,5
Reduced total brain volume and volume of some brain structures1,6-8
Cortical differences
Delayed cortical maturation in children/adolescents9-11
Reduced cortical thickness in adults.1,12"
"A significant association between the number of self-reported ADHD symptoms and total brain volume was found, such that healthy adults who reported ≥6 symptoms had a lower brain volume than those who reported ≤3 symptoms of ADHD. This study suggests that self-reported ADHD symptoms in healthy adults may have neurobiological underpinnings."

The study, funded by the Eunice Kennedy Shriver National Institute of Child Health and Human Development, found that preschoolers with ADHD showed significantly reduced brain volume across multiple regions of the cerebral cortex, including the frontal, temporal, and parietal lobes. The brain regions showing greatest ADHD-related reductions included those known to be critical for cognitive and behavioral control and predictability of behavioral symptoms."

Så här såg det ut för 10 år sedan när forskningen fortfarande trodde att ADHD-barnens outvecklade hjärnor kanske skulle "växa ikapp" de normala barnen i vuxen ålder. Är det måhända denna aspekt du finner "diskutabel"?

there was a marked delay in ADHD in attaining peak thickness throughout most of the cerebrum: the median age by which 50% of the cortical points attained peak thickness for this group was 10.5 years (SE 0.01), which was significantly later than the median age of 7.5 years (SE 0.02) for typically developing controls (log rank test chi(1)(2) = 5,609, P < 1.0 x 10(-20)). The delay was most prominent in prefrontal regions important for control of cognitive processes including attention and motor planning. "
