Clinical Trial 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.
