Navigated repetitive transcranial magnetic stimulation to correct eating behavior in obesity (clinical cases)

Obesity is a pathological condition caused by overweight and requiring medical intervention. The clinical and scientific experience gained over the past decades has allowed researchers to consider this problem as an independent disease with its own pathophysiological features, prevalence, incidence, approaches to therapy and prevention. One of the most important factors in the pathogenesis of obesity is disordered eating behavior, the central regulation of which is carried out with the active participation of the prefrontal cortex. Impact on this area (for example, using non-invasive brain stimulation) may be one of the promising ways to modulate eating behavior. The article describes clinical cases of treatment of morbid obesity using navigated rhythmic transcranial magnetic stimulation (rTMS). Different patterns of dorsolateral prefrontal cortex (DLPFC) activation before and after rTMS are demonstrated. Possible mechanisms of the influence of DLPFC on the formation of eating behavior are also considered. These data underline the important role of DLPFC dysregulation in obesity, as well as show potentially effective neuromodulation techniques.
