Research Progress of Transcranial Direct Current Stimulation Therapy for Cognitive Impairment after Stroke
Published 2024-06-01“…The stimulation site is usually the dorsolateral prefrontal lobe, but researchers have also confirmed the effectiveness of other stimulation sites, such as the bilateral M1 area and right parietal cortex. tDCS improves cognitive function by affecting neurotransmitters (such as calcium ions and γ-aminobutyric acid in astrocytes), the state of neurons, cerebral blood flow, and the connectivity of functional areas of the brain. tDCS not only produces an immediate boosting effect and an after-effect that is effective about 1 hour after stimulation, but also has long-term enhancement (LTP) and long-term depression (LTD) effects. …”
