Event-related potentials (ERPs) can provide important insights into underlying language processes in both unimpaired and neurologically impaired populations and may be particularly useful in aphasia. This scoping review was conducted to provide a comprehensive summary of how ERPs have been used with people with aphasia (PWA), with the goal of exploring the potential clinical application of ERPs in aphasia assessment and treatment. We identified 117 studies that met inclusionary criteria, reflecting six thematic domains of inquiry that relate to understanding both unimpaired and aphasic language processing and the use of ERPs with PWA. In these studies, a wide variety of ERP components were reported. Inconsistencies in reporting of participant characteristics and study protocols limit our ability to generalize beyond the individual studies and understand implications for clinical applicability. We discuss the potential roles of ERPs in aphasia management and make recommendations for further developing ERPs for clinical utility in PWA.

事件相关电位 (ERP) 可以为未受损和神经受损人群的潜在语言过程提供重要见解，并且可能对失语症特别有用。本次范围界定审查旨在全面总结 ERP 如何用于失语症 (PWA) 患者，目的是探索 ERP 在失语症评估和治疗中的潜在临床应用。我们确定了 117 项符合纳入标准的研究，反映了与理解未受损和失语症语言处理以及 ERP 与 PWA 的使用相关的六个主题调查领域。在这些研究中，报告了各种各样的 ERP 组件。报告参与者特征和研究方案的不一致限制了我们在个别研究之外进行概括和理解对临床适用性的影响的能力。我们讨论了 ERP 在失语症管理中的潜在作用，并为进一步开发 ERP 在 PWA 中的临床效用提出了建议。
