Brain Stimulation Can Treat Addiction

Stefano, a 46-year-old cocaine addict from Padua, Italy, had all but accepted that he might die from his habit. He’d just relapsed after a seven-month stay at a rehab facility, his third failed attempt at getting clean. Stefano couldn’t go more than two days without the drug. So when he read a magazine article about an unusual new method to treat drug addicts, he figured he didn’t have much to lose. The study described how local researchers were using a technique called transcranial magnetic stimulation to counteract cravings. He would have to sit in a chair while doctors waved a figure-8-shaped wand over his head to fire magnetic waves into his prefrontal cortex.



Now the results of the study, involving 29 cocaine addicts seeking treatment at a Padua clinic, are out. They suggest that the magnetic stimulation treatment significantly reduced both cocaine use and cravings. Stefano says his desire for cocaine diminished dramatically after several sessions under the magnet. The findings are generating optimism among addiction researchers, because there are no effective drug treatments available for cocaine addicts. There is also a theoretical framework to explain why stimulating the brain with magnets might work, since experiments earlier this year produced similar effects in cocaine-addicted rats.
