Whether such deficits occur after elective treatment of unruptured aneurysms remains uncertain.\u00a0A systematic search in MEDLINE (via PubMed and via Ovid), Embase, Scopus, Web of Science, CENTRAL and PsycINFO was conducted from inception to 31 August 2025, in accordance with PRISMA guidelines. Duplicate records were removed prior to screening. Studies were eligible if they included adult patients undergoing elective treatment of at least 1 unruptured AComA aneurysm, reported pre- and post-treatment neurocognitive testing across at least one cognitive subdomain, and differentiated outcomes from other aneurysm locations. Critical appraisal was performed using the Newcastle\u2013Ottawa Scale, and certainty of evidence was assessed using the GRADE framework.\u00a0Eight studies comprising 95 patients were included. In most studies, patients underwent surgical clipping (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200982), with a minority treated endovascularly (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200913). In five out of eight studies, patients who underwent elective treatment of an AComA aneurysm had worse cognitive outcomes than patients with aneurysms at non-AComA locations.\u00a0Neurocognitive deficits may be detected in a substantial proportion of patients undergoing elective treatment of unruptured AComA aneurysms when sensitive neuropsychological assessment is applied. However, the current evidence base is limited by small sample sizes, heterogeneity in neuropsychological assessment, and a predominance of surgically treated cases.\n                  <\/jats:p>","DOI":"10.1007\/s10143-026-04423-6","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T02:34:25Z","timestamp":1785465265000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Neurocognitive outcomes after treatment of unruptured anterior communicating artery aneurysms \u2013 a systematic review"],"prefix":"10.1007","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8351-1978","authenticated-orcid":false,"given":"Jorn P.","family":"Van Der Veken","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher D.","family":"Ovenden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanesa M.","family":"Tomatis","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix","family":"Paterson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vincent","family":"Oxenham","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Candice","family":"Delcourt","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marcus A.","family":"Stoodley","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2026,7,31]]},"reference":[{"key":"4423_CR1","doi-asserted-by":"publisher","first-page":"626","DOI":"10.1016\/S1474-4422(11)70109-0","volume":"10","author":"MH Vlak","year":"2011","unstructured":"Vlak MH et al (2011) Prevalence of unruptured intracranial aneurysms, with emphasis on sex, age, comorbidity, country, and time period: a systematic review and meta-analysis.
