When willpower doesn work, smokers who want to quit may have a new tool someday: magnetic brain stimulation.
A study of 115 smokers found that 13 sessions of the treatment over three weeks helped some heavy smokers quit for as long as six months.
This noninvasive technique, called repeated high-frequency transcranial magnetic stimulation (TMS), sends electric impulses to the brain. It is sometimes used to treat depression.
SmokingUsing noninvasive stimulation can reduce nicotine craving and smoking. If you stimulate regions in the brain that are associated with craving for drugs, you can change the circuitry in the brain that mediates this dependence and eventually reduce smoking, and many of those treated stop smoking.
The study participants smoked at least a pack a day and had failed at least two previous attempts to quit. The researchers divided the participants into three groups. One group received up to 10 Hz brain stimulation Discount Newport 100S Cigarettes, another 1-3 Hz stimulation, and the third received a sham treatment. The groups were further divided into those who saw a visual cue a picture of a lit cigarette just before stimulation and those who didn idea of the cue is to make sure attention is directed at smoking and not some other craving. After 13 treatments Online Newport Cigarette Store, those who received the highest level of stimulation plus the visual cue had the best results 44 percent of them had quit Buy Newport Cigarettes Wholesale. After six months, one-third of this group were still not smoking compared to 28 percent of those who weren shown the visual cue before treatment.
The results of the study were scheduled for presentation at the annual meeting of the Society for Neuroscience in San Diego.
Adding brain stimulation to other smoking cessation methods like nicotine substitution might make it even more effective.
This treatment is not a simple procedure, and the six-month results may not be as good as the success rates for other treatments, including medication and nicotine replacement, combined with behavioral components.
