Temporal Lobe Dysfunction in Medication-Naïve Boys With Attention-Deficit/Hyperactivity Disorder During Attention Allocation and Its Relation to Response Variability

Rubia, Katya, Smith, Anna B., Brammer, Michael J., Taylor, Eric·2007·Biological Psychiatry

Abstract

Background Patients with attention-deficit/hyperactivity disorder (ADHD) typically show fronto-striatal abnormalities during functions of cognitive control. In this study we investigate whether medication-naïve children with ADHD are impaired in temporo-parietal neural networks that mediate purely perceptual attention allocation to a behaviorally neutral oddball task. Furthermore, we explore the relationship between the neural substrates of attention allocation and response variability, typically increased in patients. Method Event-related functional magnetic resonance imaging was used to compare brain activation of 17 medication-naïve boys with ADHD with that of 18 handedness- and IQ-matched healthy comparison boys during a visual oddball task that required the same response to oddball and standard trials. Furthermore, to explore the relationship between behavioral dispersion and attention networks, regression analyses were conducted between response variability and brain activation networks. Results Patients showed significantly reduced brain activation in left and right superior temporal lobes, basal ganglia, and posterior cingulate during the oddball versus standard contrast. The activation differences in superior temporal lobes correlated inversely with response variability in control subjects but not in patients with ADHD. Conclusions Brain abnormalities in patients with ADHD are not confined to fronto-striatal networks mediating executive functions but are also observe…

  • On a neural level, RTV has been associated with smaller white matter tracts in the late developing fronto-parietal attention (superior longitudinal fasciculus) and cortico-thalamic cognitive control tracts and reduced activation in fronto-striatal and superior temporal activation in children and adults with ADHD.

    “In line with a role in attention and self-control, on a neural level, RTV has been associated with smaller white matter tracts in the late developing fronto-parietal attention (superior longitudinal fasciculus) and cortico-thalamic cognitive control tracts and reduced activation in fronto-striatal and superior temporal activation in children and adults with ADHD (18, 67–70), suggesting an”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
