Scientists have developed the use of brain electromagnetic stimulation technology to lose weight
According to a new study by scientists from the University of Waterloo in Canada, magnetic stimulation or electrical stimulation of the brain of obese patients may make them eat less and help them lose weight.
Sina science and technology news on April 26, Beijing time, according to foreign media reports, the latest research of scientists from the University of Waterloo in Canada found that through magnetic stimulation or electrical stimulation of the brain of obese patients, patients may eat less, which is helpful to lose weight.
In the latest study, scientists focused on testing two non-invasive brain stimulation techniques. They found that for obese patients, both electrical and magnetic pulses had good results. Usually, the main target of brain stimulation is an area called dorsolateral prefrontal cortex, which is generally related to the ability of self-control of diet. For those with eating disorders, such as bulimia and bulimia, multiple courses of noninvasive brain stimulation (usually magnetic pulses) may help.
However, the researchers also acknowledge that the current test results are not definitive. Peter Hall, a clinical psychologist and director of the preventive Neuroscience Laboratory at the University of Waterloo in Canada, said that when they applied this brain stimulation technology to patients with anorexia, the effect did not seem to be so optimistic. The latest research by hall et al. Focuses on the various therapeutic effects that non-invasive brain stimulation technology may bring, such as improving creativity, improving mathematical calculation ability and helping to treat stroke. Two common analysis techniques include direct transcranial current stimulation and repetitive transcranial magnetic stimulation.
"Many new technologies have emerged to treat eating disorders," Hall said. But as far as we know, the effect is not ideal. " By analyzing techniques such as direct transcranial electrical stimulation and repetitive transcranial magnetic stimulation, the researchers found that some techniques that stimulate the dorsolateral prefrontal cortex significantly reduce desire. In addition, three completed clinical trials and one ongoing clinical trial have shown that noninvasive brain stimulation can reduce food consumption and thus can be used to treat obesity. However, Hall's team noted that all of these studies were very short in duration and involved very few volunteers. Therefore, more clinical trials are needed for such studies.
Hall's team recently focused on bulimia and bulimia. The initial results showed that repetitive transcranial magnetic stimulation (rTMS) could inhibit the eating and drinking behavior of bulimia patients in a short time. However, the long-term efficacy has not been confirmed in trials. For bulimia, the researchers found that the results were less obvious. So far, these studies have shown that magnetic stimulation is more effective than electrical stimulation. "Direct current stimulation has proven to be less effective," Hall said. This means that repetitive transcranial magnetic stimulation is quite advanced and effective, while direct transcranial current stimulation needs further improvement
The researchers admit that noninvasive brain stimulation technology is not yet a complete cure for eating disorders and should not be seen as a panacea for all complex problems. "However, if used strategically, the technology may be an effective part of a complex treatment plan."
The scientists' findings were recently published in the journal appetite.
