脑卒中后失语症是由优势半球脑损伤引起的语言功能障碍，是脑卒中后常见的并发症之 一。经颅直流电刺激是近年新兴的非侵入性脑刺激技术，通过与功能性磁共振成像等功能成 像技术的结合，能够进一步明确脑卒中后失语症的恢复机制，以期为患者提供更加精准的个 体化治疗方案，在失语症的康复治疗中具有重大的应用前景和临床意义。本文整合了经颅直 流电刺激治疗脑卒中后失语症的最新研究，以期为失语症的康复提供更多的依据。

Post-stroke aphasia is a language function impairment caused by damage to the dominant hemisphere of the brain and is one of the common complications following a stroke. Transcranial direct current stimulation (tDCS) is an emerging non-invasive brain stimulation technique in recent years. By combining tDCS with functional imaging techniques such as functional magnetic resonance imaging (fMRI), it is possible to further clarify the recovery mechanisms of post-stroke aphasia, aiming to provide more precise and individualized treatment for subsequent patients with post-stroke aphasia. This approach has significant application prospects and clinical values in the rehabilitation of aphasia. This article integrates the latest research on tDCS for the treatment of post-stroke aphasia, intending to provide more basis for the rehabilitation of aphasia.
