Application of transcranial direct current stimulation in patients with aphasia after stroke / 国际脑血管病杂志

ABSTRACT

Post-stroke aphasia (PSA) is a common speech disorder after stroke, involving at least 1/3 of stroke patients, and causing serious adverse effects on their lives and work. The available intervention measures include speech and language rehabilitation therapy, drug therapy, and non-invasive brain stimulation technology. The latter mainly includes transcranial magnetic stimulation and transcranial direct current stimulation (tDCS). tDCS can have a positive impact on PSA by promoting its self-repair, regulating the level of neurotransmitters, and inhibiting inflammation. This article reviews the effect of tDCS on the self-recovery mechanism of PSA and its treatment.
