Cerebellar tDCS Stimulation in Children and Adult Women With Anorexia Nervosa Disorder
Hypothesis: Will the use of tDCS brain modulation in the cerebellum assist in restricted behaviors, social cognition and cognitive flexibility in women with anorexia nervosa in addition to other therapies?

Primary Outcomes:

To observe the impacts and outcomes of cerebellar transcranial direct current stimulation (tDCS) on social behaviors measured by Cyberball and Trust Game.
To observe the neuropsychological impacts of cerebellar tDCS through fMRI imaging as well as looking at the Region of Interest (ROI) of changes in the Default Mode Network and Cerebellum circuits and their activation levels in those networks.

Secondary Outcomes:

1.To observe the impacts and outcome of cerebellar transcranial direct current stimulation (tDCS) measuring the differences between anodal and cathodal stimulation. To observe potential increases in responses to social stimuli, decreases in eating disorder/depressive symptomology via cathodal stimulation. To also observe potential little to no changes in social stimuli and eating disorder/depressive symptomology via anodal stimulation.
