Abstract

Background: Cognitive models of obsessive–compulsive disorder (OCD) posit dysfunctional appraisal of disorder-relevant stimuli in patients, suggesting disturbances in the processes relying on amygdala–prefrontal connectivity. Recent neuroanatomical models add to the traditional view of dysfunction in corticostriatal circuits by proposing alterations in an affective circuit including amygdala–prefrontal connections. However, abnormalities in amygdala–prefrontal coupling during symptom provocation, and particularly during conditions that require stimulus appraisal, remain to be demonstrated directly. Methods: Amygdala–prefrontal connectivity was examined in unmedicated OCD patients during appraisal (v. distraction) of symptom-provoking stimuli compared with an emotional control condition. Subsequent analyses tested whether hypothesized connectivity alterations could be also identified during passive viewing and the resting state in two independent samples. Results: During symptom provocation, reductions in positive coupling between amygdala and orbitofrontal cortex were observed in OCD patients relative to healthy control participants during appraisal and passive viewing of OCD-relevant stimuli, whereas abnormally high amygdala–ventromedial prefrontal cortex coupling was found when appraisal was distracted by a secondary task. In contrast, there were no group differences in amygdala connectivity at rest. Conclusions: Our finding of abnormal amygdala–prefrontal connectivity during appraisal of symptom-related (relative to generally aversive) stimuli is consistent with the involvement of affective circuits in the functional neuroanatomy of OCD. Aberrant connectivity can be assumed to impact stimulus appraisal and emotion regulation, but might also relate to fear extinction deficits, which have recently been described in OCD. Taken together, we propose to integrate abnormalities in amygdala–prefrontal coupling in affective models of OCD.

  • Neuroimaging studies have reported increased amygdala activity, reduced dorsal prefrontal activity, and reduced prefrontal-amygdala functional connectivity during provocation and cognitive reappraisal of OCD-provoking stimuli.

    “Consistent with these clinical observations, neuroimaging studies have reported increased amygdala activity, reduced dorsal prefrontal activity and reduced prefrontal-amygdala functional connectivity during the provocation and cognitive reappraisal of stimuli that provoke OCD symptoms and increase physiological arousal [36, 39].”
  • ERP appears to be mediated at least partly by modulation of amygdala-vmPFC connectivity, while cognitive reappraisal dampens fronto-limbic activity through top-down dorsal prefrontal regions.

    “ERP seems to be mediated, at least in part, by modulation of amygdala-vmPFC connectivity, while cognitive reappraisal appears to dampen fronto-limbic activity via the engagement of top-down dorsal prefrontal regions [35–36, 39, 51].”
  • Difficulties recruiting dorsal prefrontal regions during cognitive reappraisal of OCD-provoking stimuli may contribute to persistent fear-related symptoms.

    “difficulties recruiting dorsal prefrontal regions for efficient emotion regulation has been reported during cognitive reappraisal of OCD-provoking stimuli in OCD [39, 60] and may contribute to the persistence of fear-related obsessive-compulsive symptoms.”
  • The cognitive reappraisal component of CBT engages dorsal prefrontal regions.

    “The cognitive reappraisal component of CBT (Table 3) trains patients to change their thoughts and emotional responses to OCD symptoms and is known to engage dorsal prefrontal regions [35–36, 39, 51].”

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.
