Abstract: BACKGROUND: At present, there are few longitudinal studies on postmenopausal cognitive impairment, and there is no systematic bibliometric analysis of its development context and hot trends. 
OBJECTIVE: To systematically integrate the related research on postmenopausal cognitive impairment with the help of bibliometric tools, identify the research trends and hot trends in this field, and promote interdisciplinary cooperation and clinical transformation. 
METHODS: The Web of Science Core Collection database was retrieved for literature related to postmenopausal cognitive impairment published from January 1, 2005 to March 24, 2025. Visualization analysis was conducted using software such as VOSviewer, the R package “Bibliometrix,” and CiteSpace.
RESULTS AND CONCLUSION: A total of 1 452 articles were included, involving 71 countries, 1 830 institutions, 510 journals, and 6 909 authors. The annual number of publications on postmenopausal cognitive impairment showed a fluctuating upward trend. The United States occupied an absolute dominant position in this field, with Stanford University, University of Pittsburgh, Harvard Medical School, and University of Illinois at the forefront. Menopause - The Journal of the North American Menopause Society had the highest number of publications (78 articles), while JAMA - Journal of the American Medical Association had the highest total number of citations (3 791 times). Espeland, Mark A. ranked first with 55 published articles; among the authors by total citations, Shumaker, Sally A. took the top spot (859 citations). From the high-frequency keyword "estrogen" (211 occurrences) and the burst keywords "progestogen addition" (strength = 15.77) and "estrogen replacement therapy" (strength = 15.57), it can be concluded that the long-term effects and safety of hormonal interventions have always been the core of research in this field. Keyword clustering revealed four research directions. Future studies may focus on constructing a "cross life cycle – multi-dimensional" research framework, which will help to more comprehensively grasp the mechanism of action of hormones on woman's cognitive function and neuropsychiatric status at different life stages. The shift in hotspot trend themes from single topics (such as magnetic resonance imaging, hormones and cognition) to diverse health topics (psychiatry and psychology, cancer risk, cardiovascular and cerebrovascular diseases, metabolic diseases, physical activity, etc.) and the shift toward non-hormonal intervention strategies reflect the development trend of the discipline.
