Scientific advances in understanding the "addiction circuitry" of the brain may lead to effective treatment for obesity using deep brain stimulation (DBS), according to a review article in the August issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.
Electrical brain stimulation targeting the "dysregulated reward circuitry" could make DBS — already an accepted treatment for Parkinson’s disease — a new option for the difficult-to-treat problem of obesity. Dr. Alexander Taghva of Ohio State University and University of Southern California was lead author of the new review.
New Insights into ‘Reward Circuitry’
Obesity is a major public health problem that is notoriously difficult to treat. Although various approaches can promote weight loss, patients typically gain weight soon after the end of treatment. Drug options have shown limited success, with several products removed from the market because of serious adverse effects. Bariatric surgery is effective in many cases of obesity but has a significant failure rate and is associated with side effects.
