Synopsis
We used resting state functional MRI data to investigate whether asymptomatic high school American football athletes undergo functional connectome (FC) changes during exposure to head acceleration events (HAEs). FCs of asymptomatic high school football athletes were shown to undergo significant changes during the season and then return to their pre-season state after the conclusion of collision activities, with changes reflected most profoundly in the somatomotor network. Late-season changes appear to affect all athletes without association with the magnitude of HAEs experienced. These observations demonstrate that participation in American football can cause significant changes in brain functionality without manifesting symptoms.
