Collaboration networks have formed across regions, institutions, and authors, but remain relatively fragmented. Core journals, influential authors, and highly cited publications have collectively shaped the foundational knowledge base of the field. Recent studies have focused on integration models and collaborative mechanisms between digital health technologies and physical activity. Future research should emphasize interdisciplinary and international collaboration, prioritizing the development of personalized, real-world-oriented digital health interventions to enhance the quality of life for older adults.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/20552076251395534","type":"journal-article","created":{"date-parts":[[2025,12,4]],"date-time":"2025-12-04T14:34:04Z","timestamp":1764858844000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Digital health-based physical activity and cognitive function in older adults: A bibliometric analysis"],"prefix":"10.1177","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0009-0005-8656-9859","authenticated-orcid":false,"given":"Qifeng","family":"Han","sequence":"first","affiliation":[{"name":"Hanyang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1890-4745","authenticated-orcid":false,"given":"Wenbo","family":"Ma","sequence":"additional","affiliation":[{"name":"Xi\u2019an University of Architecture and Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-9050-2393","authenticated-orcid":false,"given":"Zhenping","family":"Jiang","sequence":"additional","affiliation":[{"name":"Hanyang University ERICA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-2381-9961","authenticated-orcid":false,"given":"Yulin","family":"Sun","sequence":"additional","affiliation":[{"name":"Yantai University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0007-7438-8035","authenticated-orcid":false,"given":"Liang","family":"Chen","sequence":"additional","affiliation":[{"name":"Hanyang University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qian","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Physical Education, Guangzhou College of Commerce, Guangzhou, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2025,12,4]]},"reference":[{"key":"e_1_3_3_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-031-17299-1_426"},{"key":"e_1_3_3_3_2","first-page":"70","article-title":"Cognitive decline in ageing and disease: risk factors, genetics and treatments","volume":"50","author":"Colita E","year":"2024","unstructured":"Colita E, Mateescu VO, Olaru DG, et al.
