Effect of Nutritional Counseling Associated With Transcranial Direct-current Stimulation in Binge Eating Reduction

Binge eating disorder is the most prevalent eating disorder, with consequences not only economic but also social. It is related to a set of cognitive alterations related to impulsivity, cognitive function, attention, decision making, emotional control and physiological alterations in the Central nervous system (CNS) in the processing of rewards, mainly in the frontal cortical regions. Psychotherapies are the standard reference treatments, with Cognitive Behavioral Therapy (CBT) being the most indicated nonpharmacological intervention. However, the avoidance rates and the rates of non responders to treatment are significant. In view of this, it is believed that therapeutic approaches aimed at the modulation of the CNS, such as Transcranial direct-current stimulation (tDCS) may have a beneficial effect on the neurobiology of the processes that govern these disorders, thus adding to the effects of CBT and amplifying the therapeutic response.
