Key result
Adolescents with subacute sports-related concussion showed a significantly different statistical distribution of EEG information flow rates (p < 0.001) and a more symmetrical, posterior-shifted pattern of connections compared to healthy controls.
Why the study?
It remains unclear how concussion-related increases in functional connectivity relate to patterns of information flow within resting state networks and brain function in youth.
Population
32 healthy adolescents and 24 concussed adolescents with subacute concussion
Comparison
Adolescents with subacute concussion vs healthy adolescents

Adolescents with subacute sports-related concussion exhibit significantly altered, more symmetrical patterns of resting-state information flow compared to healthy controls, indicating functional reorganization of brain networks.
Hristopulos et al. (2019) conducted a case-control in Sports-related concussion (n=56). Subacute sports-related concussion vs. Healthy adolescents was evaluated on Normalized information flow rate (τi→j) distribution (p=6.5613 x 10^-126). Adolescents with subacute sports-related concussion showed a significantly different statistical distribution of EEG information flow rates (p < 0.001) and a more symmetrical, posterior-shifted pattern of connections compared to healthy controls.
