A Feasibility Study of Mindfulness Training Transcranial Direct Current Stimulation (tDCS) in Adults With Overweight and Obesity

"The MT is an established app-based programme delivered by Headspace®. During MT, participants complete guided meditation sessions which focus on mindful eating and on coping with cravings. Each MT session lasts 15 min. Participants in the MT+ real tDCS and MT+ sham tDCS groups will be given instructions to practice daily mindfulness for 3 weeks. During 10 of these sessions, MT and real/sham tDCS will be delivered concurrently.~TDCS: During tDCS, a constant weak direct current is applied via electrodes (anode and cathode) placed on the scalp. In this study, the anode will be placed over the right dorsolateral prefrontal cortex (dlPFC) and the cathode will be placed over the left dlPFC. In the real tDCS condition, stimulation will be delivered at a constant current of 2 mA with a 10 second fade in/fade out for 20 minutes. In sham tDCS, the stimulator will deliver 60 seconds of active stimulation at the start (ramping up) and end (ramping down) of the 20 minute period."
