Abstract

Background The aim of this study was to examine the functioning of fronto-striatal brain circuits that support self-regulatory capacities including conflict resolution and sequential processing in unmedicated adults with obsessive-compulsive disorder (OCD).Methods We compared functional magnetic resonance imaging blood oxygen level-dependent response in 22 adults with OCD with 22 healthy, age-matched control subjects during performance of a Simon Spatial Incompatibility task. We used general linear modeling to compare groups in their patterns of brain activation during correct responses to conflict-laden stimuli and explore the effects of trial sequence on group differences.Results Behavioral performance on the Simon task did not differ between groups. In response to conflict-laden stimuli, OCD participants activated fronto-striatal regions significantly more than control subjects, specifically a right hemisphere cluster encompassing the putamen, insula, and inferior frontal gyrus. Their activation of this cluster was driven not by conflict on a current trial but by their response to the alternation of stimulus congruence (incongruent or congruent) across trial sequences (i.e., current and preceding trials) and was most accentuated in participants with more severe symptoms in the doubt/checking dimension. Functional connectivity from the putamen to other fronto-striatal regions was also greater in the OCD compared with control participants.Conclusions When engaging the self-regulatory control necessary to resolve conflict and process alternating stimuli, OCD participants displayed excessive activation in a fronto-striatal circuit that differs from the orbitofrontal cortex-anterior cingulate cortex-caudate circuit typically implicated in OCD. Dysfunction in this circuit was associated with processing changes in the stimulus context. We speculate that this dysfunction might be related to the cognitive inflexibility typical of persons with OCD.

  • Increased activation in frontal-striatal regions, including the IFG and putamen, was seen in OCD patients during performance of a Simon task.

    “Increased activation in frontal–striatal regions, including the IFG and putamen, was seen in OCD patients during performance of a Simon task (Marsh et al., 2013).”
  • Increased functional connectivity between the putamen and the inferior parietal cortex, caudate, thalamus, and frontal areas was observed in OCD patients during performance of a Simon task.

    “Increased functional connectivity between the putamen and the inferior parietal cortex, caudate, thalamus, and frontal areas was observed in patients during performance of a Simon task (Marsh et al., 2013).”
  • The authors previously found altered conflict-related activity in frontal-striatal and insular cortices in adults with OCD during the Simon task.

    “we previously identified altered conflictrelated activity (incongruent > congruent) in frontal-striatal and insular cortices in adults with OCD performing this task (21)”
  • The authors previously found increased conflict-related activity in right insula, putamen, and inferior frontal gyrus in a similar OCD sample using the Simon task.

    “Using the Simon task, we previously detected increased conflict-related activity in the right insula, putamen, and inferior frontal gyrus in a demographically and clinically similar sample of participants with OCD (21).”

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.
