[Abstract] Objective: To explore the changes of default mode network (DMN) in CMS patients, to investigate the pathogenesis of brain lesions in patients with CMS.Materials and Methods: Twenty-four patients with clinically diagnosed CMS and age, sex, years of education, altitude matched 25 cases of normal volunteers underwent whole brain scan, and EPI images were acquired. The difference in DMN between the two groups was analyzed by defining posterior cingulate cortex (PCC) as seed region.Results: Compared with normal control group, posterior cingulate showed increased function connectivity with left parahippocampal gyrus, left angular gyrus, left medial frontal gyrus, right cerebellum 9 area and left cerebellum crus 2 area of CMS patients.Conclusion: CMS patients had changed functional connection in many regions, it might be associated with the pathogenesis of CMS patients .
