This reduction was seen in eight of our nine concussion cases. There was also a trend of improved DMN functional connectivity from Day 7 to 30. This dynamic brain alteration over one month was not seen in the normal control group. CONCLUSIONS: The functional connectivity of DMN measured with sequential rs-fMRI can potentially serve as a biomarker to monitor the dynamically changing brain function after sports-related concussion.
