Deep Brain Stimulation Could Limit Urges for Binge Eating, Study Suggests
Two women with binge eating disorder underwent this experimental treatment—and it worked.A small study found that intercepting brain signals could limit urges for binge eating for those who struggle with binge eating disorder.Experts weigh in on this experimental treatment and what it means for people with disordered eating.
Researchers asked the question: what if an uncontrollable urge to rapidly eat large amounts of food is stemmed from an impaired brain circuit? If that were the case, people who live with—a psychiatric diagnosis—might be no more at fault for overeating than a patient with Parkinson’s disease is for their tremors.
Both women who participated in this study had previously undergone bariatric surgery in an effort to reduce their weight, but for both women, the weight they lost after the surgery had been regained due to uncontrollable urges associated with binge eating disorder. Binging in general is to be exposed to something in a large quantity over a short period of time, says Dr. Sachdev. “There are reward centers that can be triggered by eating.
After connecting the devices into the women’s brains, the investigators told the participants that devices would be activated at some time during the next couple of months, but would not tell them when. Both women said that once the devices were activated, they knew immediately, because they no longer felt uncontrollable urges to binge. Now both women are seeing their weight slowly, but consistently dropping. Both say that without actively thinking about it, they are eating differently.
