The goal of this observational study is to learn if clinical and neurophysiological characteristics dynamics may follow similar trends in a longitudinal characterization of patients with a diagnosis of an eating disorder. The primary hypothesis is that the reversal of Functional Magnetic Resonance Imaging (fMRI) baseline alternations is positively associated with symptomatic amelioration. The secondary hypothesis is that the degree of (f)MRI baseline alternations is positively associated with symptoms. Participants will be asked to complete psychometric questionnaires, perform a fMRI and be recalled at 12 months for a follow-up.
