In 2008, the U.S. Food and Drug Administration approved the marketing of a device used for magnet therapy to treat depression that is considered mildly resistant to treatment, according to background information on the study provided by the U.S. National Institute of Mental Health, which funded the study.
The next step, the researchers said, is to fine-tune the treatment to determine if higher levels of magnetic stimulation or changing the location of the magnetic coil might be even more effective or if magnet therapy might work best in conjunction with medications.
In the study, the only significant side effects were headaches and mild discomfort at the stimulation site. Most participants remained depression-free for several months after treatment stopped, according to the study.
The U.S. National Institute of Mental Health has more on depression.
