Direct Current Stimulation for the improvement of Audio verbal Memory in Stroke Patients

Posted on Updated on

Post-stroke memory impairment is more common in older stroke survivors than it is in younger stroke survivors. Patients with a stroke or transient ischemic attack have higher incidence of dementia and greater whole brain atrophy than do healthy controls. As stroke prevalence increases in Japan, a method for improving memory impairment and preventing stroke recurrence is required. Trans cranial direct current stimulation is a noninvasive brain stimulation technique that involves application of a weak direct current on the scalp, which can induce temporary changes in cortical excitability and the effect of tDCS varies depending on the polarity of the electrode. Dupont performed functional magnetic resonance imaging and reported that during verbal memory tasks, healthy participants exhibited significant activation in the left inferior parietal and superior temporal cortices recent studies shows that Anodal Trans cranial direct current stimulation over the left temporoparietal area improved audio verbal memory performance and induced the primacy effect in stroke patients.
