Synopsis

In this study, based on rs-fMRI, we analyzed the dynamic characteristics of 3 groups: MCI convert to AD within one-year follow-up (1Y_AD), stable in MCI within one-year follow-up (1Y_MCI) and revision from MCI within one-year follow-up (1Y_HC), including nodal entropy and measurements of dynamic brain functional network. We found that with the disease progression, the brain functional network was reconfigured into a highly-integrated/segregated pattern, and dwell time of highly-integrated pattern is associated with executive function in 1Y_AD. These findings provide the evidence for developing dynamic measurements as potential biomarkers for tracking mechanism of AD.
