      Effect of anodal transcranial direct current stimulation at the right dorsolateral prefrontal cortex on the cognitive function in patients with mild cognitive impairment: a randomized double-blind controlled trial.
      The topic is important because there have been few randomized controlled studies with sufficient sizes on the use of the right dorsolateral prefrontal cortex anodal transcranial direct current stimulation in patients with mild cognitive impairments (MCI). The authors concluded that “anodal transcranial direct current stimulation over the right dorsolateral prefrontal cortex could enhance the accuracy of sustained attention (VSA), spatial working memory (SWM), and visual memory (VM)….”. We have many comments on the methods and findings in this study.
