Transcranial Random Noise Stimulation in Food Addiction Treatment

Effect of Transcranial Random Noise Stimulation of Prefrontal Cortex on Craving Supply Subject Suffering From Obesity

Obesity is worldwide a public health problem. According to World Health Organization (WHO), overweight and obesity are the fifth death risk factor worldwide. At least 2.8 million adults die each year. Food addiction is one of the causes of obesity that may benefit from new therapeutic options.

Transcranial random noise stimulation is a noninvasive brain stimulation technic. The modulation of the electrical activity of the right and left dorsolateral prefrontal cortex (DLPFC) by tRNS is able to act on the phenomenon of craving in other addictions. This allows us to make the assumption that tRNS stimulation could constitute a treatment for food addiction especially in obesity.
