The characteristic symptom of coronavirus disease 2019 (COVID-19) is respiratory distress, but neurological symptoms are the most frequent extra-pulmonary symptoms. This study aims to explore the current status and hot topics of neurology-related research on COVID-19 using bibliometric analysis.
Publications regarding neurology and COVID-19 were retrieved from the Web of Science Core Collection (WoSCC) on March 28 2022. The Advanced search was conducted using "TS = ('COVID 19' or 'Novel Coronavirus 2019' or 'Coronavirus disease 2019' or '2019-nCOV' or 'SARS-CoV-2' or 'coronavirus-2') and TS = ('neurology'or 'neurological' or 'nervous system' or 'neurodegenerative disease' or 'brain' or 'cerebra' or 'nerve')". Microsoft Excel 2010 and VOSviewer were used to characterize the largest contributors, including the authors, journals, institutions, and countries. The hot topics and knowledge network were analyzed by CiteSpace and VOSviewer.
A total of 5,329 publications between 2020 and 2022 were retrieved. The United States, Italy, and the United Kingdom were three key contributors to this field. Harvard Medical School, the Tehran University of Medical Sciences, and the UCL Queen Square Institute of Neurology were the major institutions with the largest publications. Josef Finsterer from the University of São Paulo (Austria) was the most prolific author. Tom Solomon from the University of Liverpool (UK) was the most cited author. and were the first two most productive journals, while held the first in terms of total citations and citations per publication. Cerebrovascular diseases, neurodegenerative diseases, encephalitis and encephalopathy, neuroimmune complications, neurological presentation in children, long COVID and mental health, and telemedicine were the central topics regarding the neurology-related research on COVID-19.
Neurology-related research on COVID-19 has attracted considerable attention worldwide. Research topics shifted from "morality, autopsy, and telemedicine" in 2020 to various COVID-19-related neurological symptoms in 2021, such as "stroke," "Alzheimer's disease," "Parkinson's disease," "Guillain-Barre syndrome," "multiple sclerosis," "seizures in children," and "long COVID." "Applications of telemedicine in neurology during COVID-19 pandemic," "COVID-19-related neurological complications and mechanism," and "long COVID" require further study.
新型冠状病毒病 2019（COVID-19）的特征性症状是呼吸窘迫，但神经系统症状是最常见的肺外症状。本研究旨在通过文献计量分析探讨 COVID-19 相关神经病学研究的现状和热点。
于 2022 年 3 月 28 日从 Web of Science 核心合集（WoSCC）中检索与神经病学和 COVID-19 相关的出版物。使用“TS =（‘COVID 19’或‘新型冠状病毒 2019’或‘冠状病毒病 2019’或‘2019-nCOV’或‘SARS-CoV-2’或‘coronavirus-2’）和 TS =（‘神经病学’或‘神经病学’或‘神经系统’或‘神经退行性疾病’或‘大脑’或‘cerebra’或‘神经’）”进行高级搜索。使用 Microsoft Excel 2010 和 VOSviewer 对最大贡献者进行特征描述，包括作者、期刊、机构和国家。使用 CiteSpace 和 VOSviewer 分析热点话题和知识网络。
共检索到 2020 年至 2022 年期间的 5329 篇出版物。美国、意大利和英国是该领域的三个关键贡献者。哈佛医学院、德黑兰医科大学和 UCL Queen Square 神经病学研究所是发表论文最多的主要机构。来自巴西圣保罗大学的 Josef Finsterer 是最多产的作者。来自英国利物浦大学的 Tom Solomon 是被引最多的作者。《柳叶刀神经病学》和《神经病学》是前两个最具影响力的期刊，而《柳叶刀》在总引用次数和每篇论文引用次数方面排名第一。脑血管疾病、神经退行性疾病、脑炎和脑病、神经免疫并发症、儿童中的神经表现、长 COVID 和心理健康以及远程医疗是 COVID-19 相关神经病学研究的核心主题。
全球范围内对 COVID-19 相关神经病学研究的关注度很高。研究主题从 2020 年的“道德、尸检和远程医疗”转向 2021 年与各种 COVID-19 相关的神经系统症状，如“中风”、“阿尔茨海默病”、“帕金森病”、“吉兰-巴雷综合征”、“多发性硬化症”、“儿童癫痫发作”和“长 COVID”。“COVID-19 大流行期间远程医疗在神经病学中的应用”、“COVID-19 相关神经系统并发症及其机制”和“长 COVID”需要进一步研究。
