Research productivity was concentrated in high-income countries, led by the United States, United Kingdom, and China, reflecting core\u2013periphery stratification and citation asymmetry. Collaboration networks showed hub dominance with dense transatlantic\u2013Eurasian linkages. Bradford analysis identified a limited core of highly productive journals. Thematic evolution revealed persistent anchoring in Alzheimer's disease, oxidative stress, and neuroprotection, with sustained prominence of coffee, caffeine, tea, and polyphenols. Recent years indicate translational expansion integrating microbiome science and computational methods. Overlay visualization demonstrated temporal stratification, highlighting emerging themes such as gut microbiota and deep learning alongside stable beverage-related cognitive frameworks.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Coffee and tea research in cognitive aging has evolved into a mature, mechanistically grounded, and globally stratified field, increasingly integrating translational, microbiome, and computational approaches in dementia-related investigations.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/13872877261450996","type":"journal-article","created":{"date-parts":[[2026,5,30]],"date-time":"2026-05-30T08:05:24Z","timestamp":1780128324000},"page":"452-470","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["A century of coffee and tea research in cognitive health and Alzheimer's disease: Structural, thematic, and translational insights (1911\u20132025)"],"prefix":"10.1177","volume":"112","author":[{"given":"Manal Mohamed Elhassan","family":"Taha","sequence":"first","affiliation":[{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6145-4466","authenticated-orcid":false,"given":"Siddig Ibrahim","family":"Abdelwahab","sequence":"additional","affiliation":[{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Khaled A.","family":"Sahli","sequence":"additional","affiliation":[{"name":"Security Forces Hospitals Program, General Directorate of Medical Services, Ministry of Interior, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Jeraiby","sequence":"additional","affiliation":[{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marwa","family":"Qadri","sequence":"additional","affiliation":[{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz","family":"Alarifi","sequence":"additional","affiliation":[{"name":"King Saud bin Abdulaziz University for Health Sciences"},{"name":"King Abdullah International Medical Research Center, Riyadh, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdullah","family":"Farasani","sequence":"additional","affiliation":[{"name":"Jazan University"},{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jobran M.","family":"Moshi","sequence":"additional","affiliation":[{"name":"Jazan University"},{"name":"Jazan University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,5,30]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1001\/jama.2025.27259"},{"key":"e_1_3_3_3_2","doi-asserted-by":"publisher","DOI":"10.1023\/A:1007614613771"},{"key":"e_1_3_3_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.tjpad.2025.100457"},{"key":"e_1_3_3_5_2","first-page":"900","article-title":"The association between coffee and caffeine consumption and renal function: insight from individual-level data, Mendelian randomization, and meta-analysis","volume":"18","author":"Mazidi M","year":"2021","unstructured":"Mazidi M, Mikhailidis DP, Dehghan A, et al.
