Casey ea 2007, Curr Opin Neurol; Swanson ea 2007, Neuropsychol Rev
MRI and fMRI studies systematically show abnormalities in prefrontal cx, n.caudatus, cerebellum & parietal cx
Increased long-range and decreased short range connectivity with age
Fair et al., 2007
Delay or interruption in these developmental processes might be associated with cognitive deficits in ADHD.
Possession of the DRD4 7-repeat allele was associated with a thinner right orbitofrontal/inferior prefrontal and posterior parietal cortex.
Participants with ADHD carrying the DRD4 7-repeat allele had a better clinical outcome and a distinct trajectory of cortical development with normalization of the right parietal cortical region.

Conclusion: closer monitoring
14-m Treatment Stage
Combined Medication &
No Treatment from Study
36 m FU
Assessment Point (Days)
Influential study, but hard to interpret at this point in time !
Stop study Tr.
Initial treatment does not seem to make a difference.
All did better.
Continuous Med (> 50% of days) versus non-continuous Med : no difference
Jensen ea 2007
All children had 3y.multimodal treatment between 6-12y
At 11-13y and 12-14y, fewer children with preschool ADHD were well-adjusted (17,7%) than controls (71.4%)
Medication works less well in preschoolers: PATS-study: 21% normalized with medication, 13% with placebo (Daley, 2007, Eunethydis)

All work (3-P somewhat less), so far no external validation (only parent ratings)
