Eating and feeding disorders (EFD's) represent the psychiatric pathology with the highest mortality rate and one of the major disorders with the highest psychiatric and clinical comorbidity. The vagus nerve represents one of the main components of the sympathetic and parasympathetic nervous system and is involved in important neurophysiological functions. Previous studies have shown that vagal nerve stimulation is effective in the treatment of resistant major depression, epilepsy and anxiety disorders. In EFD's there are a spectrum of symptoms which with Transcutaneous auricular Vagus Nerve Stimulation (Ta-VNS) therapy could have a therapeutic efficacy.
