Despite the extensive literature available to date, only some of the neurobiological mechanisms underlying the symptomatic manifestations of the disorder have been clarified, underlining the need for further research. The brain structures involved are hippocampus, amygdala, striatum, thalamus, dorsolateral prefrontal cortex, anterior cingulate cortex, and orbitofrontal cortex; furthermore, most studies have mainly focused on the expressive modalities and on the individual structural and functional alterations of the brain, generating sometimes conflicting data. The aim of this article is therefore to summarize and bring together the main evidence collected so far on what would appear to be the neuroanatomical correlates and mechanisms underlying the disorder and its manifestations, to provide a sufficiently clear and complete overview.<\/jats:p>","DOI":"10.1002\/ibra.70013","type":"journal-article","created":{"date-parts":[[2026,1,26]],"date-time":"2026-01-26T05:00:24Z","timestamp":1769403624000},"page":"86-95","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Neurobiological correlates of obsessive\u2010compulsive disorder (OCD): A narrative review"],"prefix":"10.1002","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0229-5562","authenticated-orcid":false,"given":"Giulio","family":"Perrotta","sequence":"first","affiliation":[{"name":"Department of Clinical Psychology, Faculty of Psychology Universitas Mercatorum Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anna Sara","family":"Liberati","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Faculty of Psychology Universit\u00e0 Telematica Internazionale \u201cUninettuno\u201d Rome Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,1,25]]},"reference":[{"key":"e_1_2_12_2_1","unstructured":"American Psychiatric Association.
