Effects of Transcranial Direct Current Stimulation on Working Memory in Patients with non Fluent Aphasia Disorder

摘要

Researchers aimed to investigate the effect of high intensity transdirect stimulation in (2 mA-20 min) as a helper technique in improvement of working memory and aphasia quotient in patients with non-fluent aphasia disorder. To achieve this goal, researchers evaluate the efficacy of transcranial direct current stimulation over dorsolateral prefrontal cortex of the brain upon non-fluent aphasia recovery, included 20 chronic and stroke-induced aphasia patients who each underwent 10 sessions of anodal transcranial direct current stimulation (2 mA-20 min) and 10 sessions of sham transcranial direct current stimulation (20 min) treatment. It was revealed that after transcranial direct current stimulation with 2 mA intensity and 10 sessions working memory and aphasia quotient (according to lesion location but not genders) improves significantly in non-fluent aphasia patients as compared to sham transcranial direct current stimulation. So, treatment with more sessions of anodal transcranial direct current stimulation with high intensity (2 mA-20 min) enhance working memory and functional recovery in non-fluent aphasia patients after stroke. Here, the lesion location but not gender factor plays a main role in its outcomes.
