Abstract

Background: 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.

Methods: 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.

Results: 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.

Conclusion: 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.

老年人无创脑电图研究的新趋势和热点话题：2014年至2023年文献计量分析》。

背景：脑电图（EEG）得到了迅速发展，并广泛应用于临床和科研领域。由于全球老龄化趋势，有关老年人无创脑电图的原创性研究具有重要意义。本研究旨在对这一研究领域的现状和趋势进行文献计量学概述：我们检索了 Web of Science 核心数据库中 2014 年至 2023 年间发表的文章。作为一种检索策略，我们将脑电图和老年人的同义词进行了合并。有创脑电图和二次研究被排除在外。采用在线过滤和人工审核的方式筛选出符合条件的文章。使用 VOSviewer 和 Excel 软件对基本文献计量参数进行了分析和可视化：结果：共筛选出 1656 篇文献，最终纳入了其中的 655 篇。总体而言，在过去 10 年中，论文数量稳步增长。2021 年，发表论文数量急剧上升，随后保持在较高水平。来自美利坚合众国（美国）、中国和德国等高收入国家/地区的作者和机构发表了更多论文，并做出了重大贡献。老龄神经科学前沿》、《老龄神经生物学》和《临床神经生理学》等神经科学专业期刊深受作者欢迎。有关衰老、阿尔茨海默病（AD）、轻度认知障碍（MCI）、痴呆症、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）、混淆评估方法、连通性、验证和功率：这项文献计量学研究提供了有关老年人脑电图原始研究现状和热点的基础知识，有利于研究人员为未来的神经科学和神经疾病研究做铺垫。
