Impact of transcranial direct current stimulation on food craving.

Food craving is a strong temptation and motivation to eat foods. Transcranial Direct Current Stimulation (tDCS) is a noninvasive method of stimulating or inhibiting specific areas in the cortex of brain. In this study we investigated the efficacy of tDCS on patients with food craving. This randomized clinical trial was conducted on 30 patients with food craving. The intervention group (15 patients) received 2mA direct electrical stimulation for 20 minutes. The control group (15 patients) only received sham tDCS. The patients were assessed using standardized Food Craving Questioner (FCQ-S, FCQ-T). There was no significant difference in the mean FCQ-T and FCQ-S scores between the two study groups. After the study, the mean FCQ-T score was significantly lower in the intervention group as compared to the control group. Similarly, the mean FCQ-S score in the intervention group was lower than the control group, and the difference was statistically significant. Based on the findings of this study, tDCS showed to be efficient in controlling food craving
