Associations of Observed Performance Monitoring During Preschool With Obsessive-Compulsive Disorder and Anterior Cingulate Cortex Volume Over 12 Years.

ABSTRACT: Importance:Monitoring one's performance is necessary for learning and adaptive behavior; however, heightened performance monitoring is a purported endophenotype of obsessive-compulsive disorder (OCD). The anterior cingulate cortex (ACC), a brain region implicated in the pathogenesis of OCD, is associated with performance monitoring. Whether performance monitoring early in development is an identifiable risk factor for OCD and whether early childhood performance monitoring is associated with later alterations in ACC volume are unknown. Objective:To determine whether an observed indicator of heightened performance monitoring during the preschool age is associated with later onset of OCD and altered dorsal ACC (dACC) volume through adolescence. Design, Setting, and Participants:This longitudinal observational cohort study was performed at an academic medical center as part of the Preschool Depression Study. A sample of 292 children oversampled for depression from September 22, 2003, through May 12, 2005, completed a performance-based observational task during which they received persistent negative evaluation. Blind raters behaviorally coded child performance monitoring. During the next 12 years, children completed annual diagnostic assessments; 133 completed the final behavioral follow-up and 152 contributed 1 to 3 magnetic resonance imaging scans. Follow-up was completed on August 14, 2017. Main Outcomes and Measures:Onset of DSM-5 diagnosis of OCD from baseline to the final behavioral assessment and whole-brain-adjusted dACC volume at the 3 waves of scanning. Results:Among the 292 preschool children who completed the baseline evaluation (51.4% boys; mean [SD] age, 4.5 [0.8] years), when controlling for demographic and clinical indicators, those who exhibited observed heightened performance monitoring were 2 times more likely to develop OCD (n = 35) during the next 12 years (odds ratio, 2.00; 95% CI, 1.06-3.78; P = .03). Multilevel modeling of dACC volume across the 3 scan waves (n = 152) demonstrated that heightened performance monitoring was associated with smaller right dACC volume (intercept estimate, -0.14; SE, 0.07; t = -2.17; P = .03). Conclusions and Relevance:An ecologically valid indicator of performance monitoring in early childhood was associated with onset of OCD and smaller dACC volumes in later childhood and adolescence. Early childhood observed performance monitoring is a readily observed risk factor of OCD that can be identified in preschool-aged children.

Project description:RationalePatients with obsessive-compulsive disorder (OCD) have been found to show exaggerated error responses and prediction error learning signals in a variety of EEG and fMRI tasks, with data converging on the anterior cingulate cortex as a key locus of dysfunction. Considerable evidence has linked prediction error processing to dopaminergic function.ObjectiveIn this study, we investigate potential dopaminergic dysfunction during reward processing in the context of OCD.MethodsWe studied OCD patients (n = 18) and controls (n = 18) whilst they learned probabilistic associations between abstract stimuli and monetary rewards in the fMRI scanner involving administration (on separate visits) of a dopamine receptor agonist, pramipexole 0.5 mg; a dopamine receptor antagonist, amisulpride 400 mg; and placebo. We fitted a Q-learning computational model to fMRI prediction error responses; group differences were examined in anterior cingulate and nucleus accumbens regions of interest.ResultsThere were no significant group, drug, or interaction effects in the number of correct choices; computational modeling suggested a marginally significant difference in learning rates between groups (p = 0.089, partial ƞ2 = 0.1). In the imaging results, there was a significant interaction of group by drug (p = 0.013, partial ƞ2 = 0.13). OCD patients showed abnormally strong cingulate signaling of prediction errors during omission of an expected reward, with unexpected reduction by both pramipexole and amisulpride (p = 0.014, partial ƞ2 = 0.26, 1-β error probability = 0.94). Exaggerated cingulate prediction error signaling to omitted reward in placebo was related to trait subjective difficulty in self-regulating behavior in OCD.ConclusionsOur data support cingulate dysfunction during reward processing in OCD, and bidirectional remediation by dopaminergic modulation, suggesting that exaggerated cingulate error signals in OCD may be of dopaminergic origin. The results help to illuminate the mechanisms through which dopamine receptor antagonists achieve therapeutic benefit in OCD. Further research is needed to disentangle the different functions of dopamine receptor agonists and antagonists during bidirectional modulation of cingulate activation.
