abstract = {Most structural imaging studies in ADHD have focused on
prefronto-striatal circuits. However, findings remained
inconsistent while recent reports point to the posterior
parietal cortex as an additional target for research.
Moreover, although adult ADHD clinically differs from the
childhood presentation little is known about the structural
correlates of ADHD in adults. The aim of this study was to
clarify the involvement of prefronto-striatal and posterior
parietal areas in adult ADHD.Voxel-based morphometry of high
resolution MRI scans was applied to analyze volumetric brain
differences between 31 adult patients with ADHD and 31
control subjects.The volume of prefrontal, striatal and
parietal gray matter was normal. ADHD patients displayed a
significant reduction of gray matter volume bilaterally in
the early visual cortex (P<0.04).The unexpected finding of
visual cortex abnormalities might be related to impairments
in early-stage, 'subexecutive" attentional mechanisms. The
results support the notion that executive dysfunction may
not be the dominant neurobiological characteristic of ADHD
at least in adult patients. The visual cortex deserves more
consideration as a potentially important site of dysfunction
in adult and possibly childhood ADHD.},
