abstract = {In recent years, a change in perspective in etiological
models of attention deficit hyperactivity disorder (ADHD)
has occurred in concordance with emerging concepts in other
neuropsychiatric disorders such as schizophrenia and autism.
These models shift the focus of the assumed pathology from
regional brain abnormalities to dysfunction in distributed
network organization. In the current contribution, we report
findings from functional connectivity studies during resting
and task states, as well as from studies on structural
connectivity using diffusion tensor imaging, in subjects
with ADHD. Although major methodological limitations in
analyzing connectivity measures derived from noninvasive in
vivo neuroimaging still exist, there is convergent evidence
for white matter pathology and disrupted anatomical
connectivity in ADHD. In addition, dysfunctional
connectivity during rest and during cognitive tasks has been
demonstrated. However, the causality between disturbed white
matter architecture and cortical dysfunction remains to be
evaluated. Both genetic and environmental factors might
contribute to disruptions in interactions between different
brain regions. Stimulant medication not only modulates
regionally specific activation strength but also normalizes
dysfunctional connectivity, pointing to a predominant
network dysfunction in ADHD. By combining a longitudinal
approach with a systems perspective in ADHD in the future,
it might be possible to identify at which stage during
development disruptions in neural networks emerge and to
delineate possible new endophenotypes of ADHD.},
