Weight-loss surgery failed for Robyn Baldwin so she tried deep brain stimulation to get her food cravings under control.
To target those circuits, Halpern and his colleagues believe a deep brain stimulation device — which is already used to control the tremors of Parkinson’s disease and the seizures of epilepsy — could help people who lose control around food.to test if that was the case.
“We were able to actually activate craving cells in the nucleus accumbens and hear their signal in the context of seeing pictures of food," Halpern says. The nucleus accumbens is “typically ... very quiet. But if you provoke it, all of a sudden you hear activated cells” as their electric charge changes.
“I wasn’t having any cravings for anything. I wasn’t overeating anything,” she says. “I’m not thinking about food all the time like I was before. It’s not total consuming thought. I can actually say, ‘Hey, I forgot to eat lunch today,’ which was never in my vocabulary before.” “We’re providing a level of stimulation that’s so small they can’t perceive it, but their brain circuits perceive it and change in response to that,” Halpern says.
“I’ll always have a battle with weight. … I know this is not the end-all cure. This is just an added tool for me, and it’s helping.”
