Abstract

OBJECTIVE: The purpose of this study was to determine the neural correlates of excessive habit formation in obsessive-compulsive disorder (OCD). The authors aimed to test for neurobiological convergence with the known pathophysiology of OCD and to infer, based on abnormalities in brain activation, whether these habits arise from dysfunction in the goal-directed or habit system. METHOD: Thirty-seven OCD patients and 33 healthy comparison subjects learned to avoid shocks while undergoing a functional MRI scan. Following four blocks of training, the authors tested whether the avoidance response had become a habit by removing the threat of shock and measuring continued avoidance. Task-related differences in brain activity in three regions of interest (the caudate, the putamen, and the medial orbitofrontal cortex) were tested at a statistical threshold set at <0.05 (family-wise-error corrected). RESULTS: Excessive habit formation in OCD patients, which was associated with hyperactivation in the caudate, was observed. Activation in this region was also associated with subjective ratings of increased urge to perform habits. The OCD group, as a whole, showed hyperactivation in the medial orbitofrontal cortex during the acquisition of avoidance; however, this did not relate directly to habit formation. CONCLUSIONS: OCD patients exhibited excessive habits that were associated with hyperactivation in a key region implicated in the pathophysiology of OCD, the caudate nucleus. Previous studies indicate that this region is important for goal-directed behavior, suggesting that habit-forming biases in OCD may be a result of impairments in this system, rather than differences in the buildup of stimulus-response habits themselves.

  • Impaired functional connectivity between these regions disrupts the balance between goal-directed and habitual systems, causing excessive habitual responding and a struggle to shift to goal-directed actions.

    “Moreover, impaired functional connectivity between these regions disrupts the balance between goal-directed and habitual systems, causing excessive habitual responding and a struggle to shift to goal-directed actions (16, 198, 199).”

    From Neural mechanisms underlying cognitive inflexibility in obsessive-compulsive disorder: a review (2026) · cites this paper as [199]

    The Results (fMRI; page unavailable) report connectivity differences between OCD patients who formed habits and those who did not, but no overall connectivity difference between patients and controls. The Discussion suggests that excessive caudate–subgenual ACC connectivity may compromise goal-directed control. It does not establish that impaired connectivity causes a disrupted balance or difficulty shifting to goal-directed actions. (LLM, conf=0.86)

  • The functional/causal relationship between obsessions and compulsions is not always clear; despite a traditional view that obsessions lead to compulsions, this may not always be the case.

    “The functional/causal relationship between obsessions and compulsions is not always clear—despite a traditional view that obsessions lead to compulsions, this may not always be the case (Abramowitz & Jacoby, 2014; Gillan et al., 2015; Gillan et al., 2016; Robbins et al., 2019).”

    From Obsessive-compulsive disorder: Etiology, neuropathology, and cognitive dysfunction (2023) · cites this paper as Gillan et al., 2015

    The Introduction describes compulsions as habit-like actions that can persist despite being unwanted, and the Discussion says the interaction between fear learning and habits in OCD is likely complex. This supports questioning a simple account of what drives compulsions, but our copy does not directly examine whether obsessions cause compulsions or describe the traditional obsessions-first view. No page numbers are available in our copy. (LLM, conf=0.79)

  • Dysfunction in these areas disrupts the balance between goal-directed and habitual behaviors, contributing to the characteristic symptoms of OCD.

    “Dysfunction in these areas disrupts the balance between goal-directed and habitual behaviors, contributing to the characteristic symptoms of OCD (193, 199).”

    From Neural mechanisms underlying cognitive inflexibility in obsessive-compulsive disorder: a review (2026) · cites this paper as [199]

    The Introduction describes OCD as involving dysfunction in systems supporting habits and goal-directed control. The Discussion links excessive habits to failures in goal-directed control associated with caudate and possibly mOFC hyperactivity. But the paper presents this as support for a model of OCD, not as proof that dysfunction in these areas causes its characteristic symptoms. (LLM, conf=0.83)

  • Anxiety is not always causal in triggering compulsive-like behaviors.

    “and that anxiety is not always causal in triggering compulsive‐like behaviors (Gillan & Robbins, 2014; Gillan et al., 2015; Gillan et al., 2014).”

    From Obsessive-compulsive disorder: Etiology, neuropathology, and cognitive dysfunction (2023) · cites this paper as Gillan et al., 2015

  • The bias towards increased habit formation in OCD extends to avoidant habits that may be more relevant to clinical symptoms.

    “this bias towards increased habit formation in OCD not only applies to appetitive habits, it also extends to avoidant habits that may be more relevant to the clinical symptoms seen in patients76,77.”

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.
