Postmenopausal cognitive impairment: a bibliometric analysis of developmental context and hot trends

• Annual publications on postmenopausal cognitive impairment have shown a fluctuating upward trend over the past two decades, indicating growing research interest. • The United States leads in research output, with top institutions including Stanford University, University of Pittsburgh, Harvard Medical School, and University of Illinois. • Hormonal interventions, particularly estrogen therapy and its long-term safety, remain the central focus, as evidenced by high-frequency and burst keywords. • Research themes have expanded from single topics like MRI and hormones to broader health issues (psychological, tumor risk, cardiovascular, metabolic, physical activity), with a shift toward non-hormonal intervention strategies.
