Abstract

This study aimed to systematically characterize the global research landscape, collaboration patterns, knowledge structure, and emerging hotspots of glucagon-like peptide-1 receptor agonists in neurodegenerative diseases using bibliometric methods. Publications related to glucagon-like peptide-1 receptor agonists and neurodegenerative diseases were retrieved from the Web of Science Core Collection from 2006 to 2025. Only English-language articles and reviews were included. Bibliometric analyses were performed using Bibliometrix, VOSviewer, and CiteSpace to evaluate annual publication trends, country and institutional contributions, author collaborations, journal distribution, citation structures, keyword co-occurrence, thematic evolution, and citation bursts. A Scopus-based sensitivity analysis was conducted to assess the robustness of the main bibliometric findings. A total of 1,202 publications were included, with annual output increasing from 2 in 2006 to 241 in 2025, particularly after 2020. China, the USA, and England were the leading contributors and major collaboration hubs. Shanxi Medical University, Lancaster University, and the National Institute on Aging were among the most productive institutions, while major journals included International Journal of Molecular Sciences, Neuropharmacology, European Journal of Pharmacology, Frontiers in Endocrinology, Frontiers in Pharmacology, and Journal of Alzheimer's Disease. Keyword and citation analyses indicated a thematic shift from exendin-4, Alzheimer's disease, Parkinson's disease, and neuroprotection toward semaglutide, neuroinflammation, cognitive impairment, clinical efficacy, evidence synthesis, and combination therapy. Research on glucagon-like peptide-1 receptor agonists in neurodegenerative diseases has expanded rapidly over the past two decades. Current bibliometric evidence suggests that this field has evolved from preclinical exploration toward broader translational and clinical research, with increasing attention to neuroinflammation, metabolic dysfunction, cognitive outcomes, and newer incretin-based therapies. However, the therapeutic implications of glucagon-like peptide-1 receptor agonists for neurodegenerative diseases remain to be further validated by high-quality mechanistic studies and well-designed clinical trials.
