The purpose of this study is to evaluate the research hotspots and trends in comorbidity studies of osteoporosis and cognitive impairment through literature visualization analysis and provide valuable insights for further applications and research in this field. Methods: Using the Web of Science database, relevant literature on co-morbidity studies of osteoporosis and cognitive impairment published until October 20, 2023, was retrieved. CiteSpace was employed to analyze the publication trends, countries, institutions, author collaborations, co-occurring keywords, and burst keywords in this research area. Results: A total of 917 relevant publications on co-morbidity studies of osteoporosis and cognitive impairment were included in the analysis. The research in this area is primarily concentrated in countries such as the United States, Italy, China, the United Kingdom, and Australia. High-impact authors include Julie A. Pasco and Sophia X. Sui. Cluster analysis revealed key topics such as hip fractures, bone density, cognitive impairment, breast cancer, and randomized trials. The top three burst keywords, ranked by burst strength, were quality of life, postmenopausal women, and hormone replacement therapy. Conclusion: The number of co-morbidity studies on osteoporosis and cognitive impairment has been steadily increasing in recent years. However, based on the results from CiteSpace, we recommend more active collaboration among countries, institutions, and authors to facilitate clinical and basic research. Current research focuses on exploring the correlation and epidemiological characteristics of osteoporosis and cognitive impairment. Developing simple, reliable early screening methods and effective early interventions may become the research hotspots for the management of co-morbidity between osteoporosis and cognitive impairment.
