Abstract
- Objective: To examine the effect of nutritional counseling therapy (NCT) combined with transcranial direct current stimulation (tDCS) on Binge Eating Disorder (BED) symptoms.<br />Methods: 40 women with BED were randomly (ratio of 2:2:2) allocated to one of the groups: active tDCS (a-tDCS), NCT, sham tDCS (s-tDCS) with NCT, and a-tDCS with NCT. Home-based tDCS was applied to the dorsolateral prefrontal cortex for 28 sessions.<br />Results: A mixed analysis of variance showed no main effect between groups or a time × group interaction. However, a significant main effect was found for time on the primary outcome: Binge Eating Scale (p = 0.001; eta2p= 0.325), which tended to decrease during treatment and follow-up. A significant main effect was found on the secondary outcome: short-interval intracortical inhibition (SICI) (p = 0.02; eta2p= 0.112), a measure of inhibitory function, which increased from baseline to the final period in the a-tDCS group, without significant differences between groups.<br />Conclusions: These findings reveal that the combined therapy did not have a synergic effect on BED symptoms. Since this is a pilot study and this is a promising area, we provide data to plan future larger-scale studies investigating the effects of tDCS and behavioral interventions in BED treatment.<br />Competing Interests: The authors report no conflicts of interest.
