Bibliometric analysis of natural medicine in the treatment of Alzheimer's disease: Trends, hotspots, and emerging research fields.

BackgroundAlzheimer's disease (AD) is a progressive neurodegenerative disorder whose global prevalence continues to rise, yet treatment options are still limited. Natural medicines, with their potential for multi-target intervention, have become a key direction in AD drug development. However, a systematic overview of research trends in this field based on bibliometric methods is currently lacking.ObjectiveThis study aims to summarize research progress on natural medicines for AD treatment using bibliometric analysis and to identify future research hotspots and trends.MethodsRelevant publications were retrieved from the Web of Science Core Collection. Data visualization and analysis were conducted using VOSviewer, CiteSpace, and R.ResultsA total of 3800 publications were included, involving contributions from 108 countries/regions, 4024 institutions, 18,729 authors, and 706 journals. Publication output showed steady growth, with China and India as the leading contributing countries. Institutions such as the Chinese Academy of Sciences and Kyung Hee University demonstrated high productivity and influence. The research focus has shifted from initial clinical pharmacology and molecular pathology to exploring multi-target mechanisms of natural medicines through network pharmacology and molecular docking. Promising natural agents include Ginkgo biloba, ginseng, curcumin, resveratrol, and Centella asiatica.ConclusionsResearch on natural medicines for AD has progressed steadily over the past two decades, with current emphasis on elucidating multi-target mechanisms using emerging technologies. However, clinical evidence remains limited. Future studies should strengthen multi-omics integration and clinical translation to foster innovative AD prevention and treatment strategies.
