摘要：

经颅直流电刺激是诱导或增强神经可塑性的无创性、安全方法，治疗脑卒中后失语有一定效果。本文拟对脑卒中后失语患者言语功能恢复的可能机制进行探讨，分析双侧大脑半球和小脑在言语功能恢复中的作用，并进一步总结经颅直流电刺激在脑卒中后失语治疗中的研究进展。

Abstract:

Transcranial direct current stimulation (tDCS), which is a safe and noninvasive method for inducing or enhancing neural plasticity, can promote the recovery of post-stroke aphasia (PSA). This paper explores the possible mechanisms of verbal recovery in patients with PSA, and analyzes the role of bilateral hemispheres and cerebellum in speech recovery to review the research progress of application of tDCS in PSA.
