In conclusion, the current investigation adopted graph-based
analysis to study the whole brain network manifestation of neurological
dysfunctions in MCI patients compared with normal controls.
The present study suggested that the pathological networks in MCI
patients had topological abnormalities in whole brain networks
and loss of small-world attributes both during active and resting
states. All the characteristics observed inMCI may reflect anatomical
structural abnormalities. Such a relationship may contribute to an
understanding of the cerebral organization in MCI. Furthermore,
we found visual stimuli especially conflict stimuli evoked more efficient
brain network.
