The transcranial direct current stimulation (tDCS) is a “do-it-yourself” type of brain stimulation people use for cognitive enhancement and in the treatment of anxiety or depression. A recent study shows that these devices could do more harm than good.
Despite its popularity and promise, a group of researchers from the University of Pennsylvania’s Perelman School of Medicine, Beth Israel Deaconess Medical Center (Harvard Medical School teaching hospital) as well as several experts in the neuroscience research community, has issued a warning about the home use of tDCS and the risks that come with it.
