Impulsivity has been implicated in refractory obesity. The dorsolateral prefrontal cortex (DLPFC) may counterbalance overactive brain reward by enhancing executive function (EF), including impulse control, mitigating loss-of-control eating. Galioto found that EF predicted weight-loss in structured medical weight-loss programs (Galioto 2016). Cognitive training (CT) monotherapy for EF improvement has not shown sufficient therapeutic promise nor has DLPFC-directed transcranial direct current stimulation (tDCS), but coupled, they may enhance EF. The aim of this study was to determine if tDCS coupled with computerized CT decreased impulsivity in individuals with obesity.
