Global trends and research hotspots in autoimmune encephalitis: insights from a bibliometric and visualized analysis: 1971-2025.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Autoimmune encephalitis (AE) encompasses a highly heterogeneous spectrum of severe immune-mediated neurological disorders. Over the past 50 years, research has expanded rapidly, yet a quantitative synthesis of its evolution, key contributors, and thematic trends is lacking. Here, we provide a comprehensive 50-year, multi-database bibliometric study that systematically maps the full trajectory of AE research-from early descriptions to the current era of mechanism-driven therapeutics-using advanced analytical tools. Methods: We systematically retrieved AE-related publications from 1971 to May 24, 2025 from PubMed, Web of Science, and Scopus. After deduplication, records were analyzed using bibliometric tools (CiteSpace, VOSviewer, Bibliometrix). Analyses included publication trends, national/institutional contributions, author networks, journal distributions, co-citation patterns, keyword co-occurrence, and thematic evolution. Results: Annual publications surged after 2007, coinciding with the discovery of anti-NMDA receptor encephalitis (anti-NMDAR AE), reaching a peak in 2022. The USA and China were the leading contributors by volume, while Spain had the highest average citation impact. The University of Pennsylvania and the University of Oxford emerged as the most productive institutions. Dr. Josep Dalmau is the most prolific author in the field, leading a major collaborative cluster. Frontiers in Neurology published the most papers, while Neurology had the highest H-index. Keyword and thematic analyses confirmed anti-NMDAR AE as the dominant research focus, with intense scholarly interest in its pathogenesis, diagnosis, and immunotherapy. Recent trends highlight emerging topics like COVID-19-associated AE, anti-IGLON5 disease. Conclusions: This study outlines the development, collaboration patterns, and research hotspots in AE. Research continues to center on anti-NMDAR encephalitis, with a growing focus on clinical and therapeutic applications. Future directions include mechanistic studies, biomarker discovery, and advanced immunotherapies.
