Reduced Functional Connectivity in the Default Mode Network in EEGs without Other Abnormalities in Early Creutzfeldt-Jacob Disease

Our findings provide evidence of disruption of the DMN in the gamma band and alterations of FC between specific brain regions in early CJD patients with visually normal EEGs. EEG brain network properties bear potential as a diagnostic tool for CJD early in the disease course in addition to established criteria. These findings call for further studies evaluating the diagnostic value of FC in early CJD.
