This scoping review examines the role of dopamine in OCD, focusing on its impact on neural circuits, brain regions, and behavioral manifestations. Evidence from 19 studies reveals consistent dopaminergic dysfunction across key brain structures, particularly in the cortico-striato-thalamo-cortical (CSTC) circuits. Altered dopamine receptor availability was observed in the dorsal striatum, ventral striatum, and anterior cingulate cortex, contributing to cognitive rigidity, emotional dysregulation, and compulsive behaviors. Pharmacological findings highlight the complexity of dopamine's role, with both hyperdopaminergic and hypodopaminergic states influencing symptoms. Dopamine antagonists and partial agonists have demonstrated efficacy in targeting overactivation of striatum and restoring cortical balance. These findings underscore the importance of dopamine as a therapeutic target and highlight the need for circuit-specific interventions and tailored treatment strategies.</div></div>","PeriodicalId":16868,"journal":{"name":"Journal of psychiatric research","volume":"194 ","pages":"Pages 11-20"},"PeriodicalIF":3.2,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145799814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the biopsychosocial correlates of FAD are documented, its specific neurocognitive correlates remain unexplored, despite extensive literature describing the distinct neurocognitive correlates of alcohol consumption and eating disorders. We therefore investigated whether FAD is associated with neurocognitive correlates in university students and examined whether different FAD sub-dimensions relate to distinct cognitive profiles. We assessed FAD in 130 French university students using the CEBRACS scale and administered an extensive neuropsychological battery measuring visuospatial abilities, episodic memory, and executive functions. We compared cognitive performance between individuals who do and do not engage in FAD and then conducted exploratory multivariate regression analyses to identify variations in cognitive profiles across the CEBRACS subscales. The general comparison between individuals who do and do not engage in FAD did not reveal significant differences. Conversely, analyses of the CEBRACS subscales identified specific patterns: (1) dietary restraint was associated with poorer visuospatial abilities and verbal episodic memory; (2) purging behaviors were associated with lower executive functioning but improved visual episodic memory; (3) extreme fasting and self-induced vomiting were associated with poorer visual episodic memory performance but higher executive functioning.
