Brief Summary
Eating disorders (EDs) are severe chronic psychiatric disorders with a not fully understood etiopathogenesis. Previous studies have revealed some biological mechanisms of EDs. However, the etiology and maintenance mechanism of EDs, especially the neuro-mechanisms is still unknown. To explore the pathogenic mechanism and treatment biomarkers of EDs, we design this study. the multidimensional data including the clinicopathological features, neuroimaging data (functional and structural magnetic resonance imaging), electroencephalogram and inflammatory cytokines will be used to investigate the biomarkers for diagnosis and treatment effectiveness.

Outcome Measures
Primary Outcomes (2)
The change of severity of illness at 8 weeks
The change of scores of Eating disorder Inventory (EDI) will be used to estimate the change of severity of illness. The scores of 8-week will be compared with those of baseline. The maximum of EDI is 396 and the minimum score is 0.
Day 0 to Day 56
The change of eating disorder behaviors and cognition
The change of scores of Eating Disorder Examination Questionnaire (EDEQ) will be used to estimate the change of behaviors and cognition during treatment.The maximum score of EDEQ is 32.5 and the minium score is 0.
Day 0 to Day 56
Secondary Outcomes (2)
The change of severity of illness at early or later timepoints during treatment
Day 0 to Day 28; Day 0 to Month 3; Day 0 to Month 6; Day 0 to Month 12
The change of eating disorder behaviors and cognition
Day 0 to Day 28; Day 0 to Month 3; Day 0 to Month 6; Day 0 to Month 12
