Synopsis

Repetitive head impact exposure (RHIE) during contact sports may have damaging neurocognitive effects. In this study, we investigated longitudinal changes in dynamic functional connectivity (dFNC) using multiband multi-echo (MBME) fMRI in high school football players over the course of two seasons. Four recurring connectivity states were identified. A greater total number of dFNC changes were observed over two seasons compared to over the course of one season. Changes across all four states were only observed in the two-season comparison. These preliminary results suggest that RHIE may lead to accumulated effects in functional connectivity patterns.
