Pulsing Magnetic Waves In The Brain Could Help Heavy Smokers Ditch Their Habit

A machine that pulses deep regions of the brain with magnetic current may help heavy smokers quit the habit, an Israeli study shows.
In the study, which experts say is the most rigorous test of the technology to date, 44 percent of a group of heavy smokers who had failed to quit using other methods were finally able to stop after a few weeks of treatment. One third of the smokers who were treated had still not lit up six months later. It may not sound like a high success rate, but failure rates of other anti-smoking methods can reach about 90 percent.
The magnetic current method stimulates regions of the brain that are central to addiction, using a specially designed helmet. It’s is able to turn the brain regions’ electrical activity up or down – apparently making quitting easier.
“We appear to have changed the electrical activity of brain networks in ways that helped people to quit smoking,” said Prof. Abraham Zangen, a brain scientist at Ben-Gurion University of the Negev, who helped invent the machine and led the prospective double-blind cohort study. “Heavy smokers who failed previous attempts to stop smoking with medications, with nicotine patches, with psychotherapy – they made it.”
Based on the results of the study, published in the journal Biological Psychiatry in July, the US Food and Drug Administration is now testing the machine for approval.
