Electroencephalography (EEG) has been rapidly developed and is widely used in both clinical and scientific fields. Original studies on non-invasive EEG in the elderly have been of great importance owing to the global aging trend. The present study aimed to provide a bibliometric overview on current status and trends in this research field.
We searched the Web of Science Core Collection for articles published during 2014 and 2023. Synonyms for EEG and the elderly were combined as a retrieval strategy. Invasive EEG and secondary studies were excluded. Online filters and manual reviews were applied to select eligible articles. Basic bibliometric parameters were analyzed and visualized using VOSviewer and Excel software.
A total of 1656 publications were filtered, and 655 of which were finally included. In general, publication counts have steadily increased over the last 10 years. A sharp rise in publications occurred in 2021, and then remained at a high level. Authors and institutions from high-income countries/regions such as the United States of America (USA), China, and Germany were more productive and made significant contributions. Journals specialized in neuroscience, such as Frontiers in Aging Neuroscience, Neurobiology of Aging, and Clinical Neurophysiology, were popular among authors. Articles on aging, Alzheimer's disease (AD), mild cognitive impairment (MCI), dementia, memory, event-related potentials, attention, and the brain were more likely to use EEG. The newer topics included anesthesia, postoperative delirium (POD), confusion assessment method, connectivity, validation, and power.
This bibliometric study provides fundamental knowledge on the current status and hot spots of the original studies on EEG in elderly, which is beneficial to researchers in paving future investigations of neuroscience and neural diseases.
脑电图（EEG）发展迅速，在临床和科研领域都有广泛应用。鉴于全球老龄化趋势，关于老年人非侵入性脑电图的原创性研究具有重要意义。本研究旨在对该研究领域的现状和趋势进行文献计量学综述。
我们在科学网核心合集中搜索了2014年至2023年发表的文章。将EEG和老年人的同义词组合作为检索策略。排除侵入性脑电图和二次研究。应用在线筛选器和人工评审来选择符合条件的文章。使用VOSviewer和Excel软件对基本文献计量参数进行分析和可视化。
共筛选出1656篇出版物，最终纳入655篇。总体而言，过去10年发表数量稳步增加。2021年出版物数量急剧上升，然后保持在高水平。来自美国、中国和德国等高收入国家/地区的作者和机构生产力更高，做出了重大贡献。神经科学专业期刊，如《衰老神经科学前沿》《衰老神经生物学》和《临床神经生理学》，在作者中很受欢迎。关于衰老、阿尔茨海默病（AD）、轻度认知障碍（MCI）、痴呆、记忆、事件相关电位、注意力和大脑的文章更有可能使用脑电图。较新的主题包括麻醉、术后谵妄（POD）、意识模糊评估方法、连通性、验证和效能。
这项文献计量学研究提供了关于老年人脑电图原创性研究现状和热点的基础知识，有助于研究人员为未来的神经科学和神经疾病研究铺平道路。
