This review synthesizes current knowledge regarding structural and functional alterations in key brain regions associated with PDN, including the thalamus, striatum, anterior cingulate cortex, insular cortex, and hippocampus. Additionally, it explores the role of the descending pain modulatory system and other cerebral structures in the pathophysiology of PDN. Further research is warranted to elucidate the mechanisms driving these cerebral changes and to evaluate their potential as therapeutic targets for improving PDN management.</p></div>","PeriodicalId":100082,"journal":{"name":"Anesthesiology and Perioperative Science","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s44254-025-00151-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147336173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
