Abstract

Background Atomoxetine, a highly selective noradrenaline reuptake inhibitor (SNRI), shows efficacy in the treatment of attention-deficit/hyperactivity disorder (ADHD). Compared with psychostimulants, atomoxetine has a distinct mode of brain action and potentially lower addictive potential. Studies have yet to assess whether atomoxetine improves cognition following a single oral dose in ADHD. Methods Twenty-two adults with DSM-IV ADHD were administered a single oral dose of atomoxetine (60 mg) in a placebo-controlled double-blind crossover design. Cognitive effects were assessed using stop-signal, sustained attention, spatial working memory, and set-shifting paradigms. Normative cognitive data from 20 healthy volunteers were collected for comparison. Results The ADHD patients under placebo conditions showed response inhibition and working memory deficits compared with healthy volunteers. Atomoxetine treatment in the ADHD patients was associated with shorter stop-signal reaction times and lower numbers of commission errors on the sustained attention task. Conclusions Atomoxetine improved inhibitory control, most likely via noradrenergically mediated augmentation of prefrontal cortex function. These results have implications for understanding the mechanisms by which atomoxetine exerts beneficial clinical effects and suggest novel treatment directions for other disorders of impulsivity.

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.
