Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

Even when they know it can improve health, many individuals with loss of control eating struggle when they are trying to make and sustain new health habits for weight loss and maintenance of weight loss. Impulsivity, characterized by lack of foresight and planning and excessive risk taking, and compulsivity, characterized by inability to break old habitual behaviors, may play a role in refractory obesity. The primary objective of this pilot study is to investigate the effect of a novel neuroplasticity based intervention, cognitive training coupled with transcranial direct current stimulation (tDCS), on measures of impulsivity and compulsivity in individuals with obesity.
