I had to get into the medical publications on this subject because a friend approached me one year ago with the idea of commercializing tDCS devices. I warned him that it looked like a fraud.

The thing is, scientists are using transcranial MAGNETIC stimulation (TMS) more and more these days as interesting results are appearing. However, TMS is hard to do correctly. In the meantime, tDCS got branded as "almost the same thing" (I suspect that "tDCS" is a new term purposefuly chosen to sound similar to TMS) and quoted publications about TMS to claim a proven effect.

tDCS is pretty easy: put two electrodes on the cranium and impose a small current between them. Mass-manufacturing them is easy and cheap. The only problem is that they have nothing to do with the tech proven to work.
