To explore the influences of brain microbleeds (BMBs) on structural brain network in stroke
patients, we used DTI-based tractography and brain network analysis to
investigate the brain structural network configuration in stroke patients with
and without BMBs. Our results demonstrated disrupted balance between integrated
and segregated process in global network, and enhanced specialized functions in
stroke patients with BMBs. These findings suggested that the presence of BMBs is
related to a disturbed brain network organization with imbalanced integrated
and segregated information process ability, and brain network analysis is a sensitive tool to assess the impaired cognition caused by cerebral small vessel disease.
