Sounds like a bunch or crap to me. Let's say it does work though, what else does a person risk losing when they zap your brain? I would rather not take this sort of risk without having more information as it could have devastating effects that weren't desired.
It kind of reminds me when Lobotomies were very popular in the United States and they were sold by psychiatrists and medics in asylums as the best treatment one could find to treat those who were suffering from alcoholism to depression, basically any mental illness which made the individual to struggle in society. The consequences are pretty obvious now once we take a retrospective look at what happened to many of those patients who survived the procedure, they became kid of shells of their former beings, with their intellect reduced and the capacity to react numbed by having part of their brain severed from the rest.
When comes to directly messing with one's brain for the sake of treatinf behavioral disorders, one needs to be very careful, so we all won't repeat the history which is now a permanent stain in history of medicine and mental healthcare.
