This structured narrative review synthesizes current evidence on mechanisms, neuropsychological assessment, neuroimaging correlates, clinical and demographic risk factors, emerging artificial intelligence and machine learning applications, and non-pharmacological approaches to CRCI in breast cancer. A structured literature search was conducted using PubMed\/MEDLINE, PsycInfo, and Clinical Key up to May 2026, with emphasis on studies published between 2023 and 2026. Peer-reviewed English-language studies involving adult breast cancer populations and addressing predefined thematic domains of CRCI were considered. Given the heterogeneity of study designs, assessment tools, interventions, and outcomes, the findings were synthesized narratively. Current evidence supports a multifactorial model of CRCI involving neurobiological, treatment-related, psychological, and behavioral mechanisms. Neuroinflammation, endocrine disruption, oxidative stress, glial alterations, and structural or functional brain changes may contribute to cognitive symptoms; however, the strength of evidence varies, and many findings remain correlational or preclinical. Non-pharmacological interventions, including cognitive training, physical activity, mindfulness-based and psychological approaches, and multimodal digital programs, appear promising as supportive strategies. However, evidence remains heterogeneous, with benefits more consistently reported for patient-reported outcomes, fatigue, emotional distress, and quality of life than for objective neuropsychological performance. CRCI in breast cancer should be approached as a heterogeneous condition requiring early recognition, standardized assessment, and multidisciplinary supportive care. Future research should prioritize longitudinal designs, harmonized endpoints, and a clearer distinction between subjective and objective outcomes.<\/jats:p>","DOI":"10.3390\/cancers18121974","type":"journal-article","created":{"date-parts":[[2026,6,17]],"date-time":"2026-06-17T15:11:22Z","timestamp":1781709082000},"page":"1974","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cancer-Related Cognitive Impairment in Breast Cancer: Current State of Knowledge, Mechanisms, Diagnosis, Prevention and Treatment"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2111-3728","authenticated-orcid":false,"given":"Federica","family":"Andreis","sequence":"first","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-5881-1215","authenticated-orcid":false,"given":"Chiara","family":"Deori","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-0000-1484","authenticated-orcid":false,"given":"Valentina","family":"Giubileo","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Abeni","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7422-0119","authenticated-orcid":false,"given":"Irene","family":"Caramella","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sara","family":"Cherri","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brunella","family":"Di Biasi","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michela","family":"Libertini","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7423-6065","authenticated-orcid":false,"given":"Silvia","family":"Noventa","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chiara","family":"Ogliosi","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7861-7882","authenticated-orcid":false,"given":"Ester","family":"Oneda","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tiziana","family":"Prochilo","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fausto Angelo","family":"Meriggi","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0817-4633","authenticated-orcid":false,"given":"Alberto","family":"Zaniboni","sequence":"additional","affiliation":[{"name":"Oncology Department, Istituto Ospedaliero Fondazione Poliambulanza, via Bissolati 57, 25124 Brescia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,17]]},"reference":[{"key":"ref_1","first-page":"229","article-title":"Global cancer statistics 2022: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries","volume":"74","author":"Bray","year":"2024","journal-title":"CA Cancer J.
