New Treatment Perspectives in Adolescents With Anorexia Nervosa: the Efficacy of Non-invasive Brain-directed Treatment

The investigators hypothesized that excitatory tDCS over the left PFC and inhibitory tDCS over the right PFC (anode left/cathode right) may aid in altering/resetting inter‐hemispheric balance in children and adolescents with AN, reducing their control over eating behaviors and improving the AN psychopathology. Furthermore, the investigators will employ TMS‐EEG to directly explore the DLPFC activity of children and adolescent with AN, with specific attention to the differences between hemispheres. Moreover, paired pulse TMS and repetitive TMS protocols will be used to investigate the functional mechanisms within the prefrontal cortex of youth patients with AN. Then, the investigators will assess if potential changes of specific biomarkers, such as those related to the endogenous stress response system functioning, will occur after tDCS treatment and will correlate with clinical improvement.
