Adolescence is a critical period of neurodevelopment characterized by functional brain network reorganization. Sport-related concussions (SRCs) cause transient disruptions to functional connectivity patterns, but the long-term effects on network maturation remain unclear. The default mode network (DMN), frontoparietal network (FPN), and salience network (SN) are commonly disrupted during SRC recovery. Using biennial resting-state functional magnetic resonance imaging (rs-fMRI) from the Adolescent Brain and Cognitive Development (ABCD) study, we evaluated changes in functional connectivity in adolescents without any SRC history (n=1165; TBINaive), with an SRC between the ages of 10 and 12 (n=56; TBIEarly), and with an SRC between the ages 12 to 14 (n=40; TBILate) using annual concussion history screening. Separate repeated-measure analysis of variance (ANOVA) tested changes in network segregation, within-network, and between-network connectivity within each group over time (baseline, year 2, year 4). TBINaive exhibited increased DMN, FPN, and SN segregation (p < 0.0001) driven by increased DMN and FPN connectivity (p < 0.0001) and decreased whole-brain connectivity (p < 0.0001). DMN-FPN, DMN-SN, and FPN-SN connectivity also increased (p ≤ 0.014). TBIEarly exhibited limited changes, with disrupted FPN and SN segregation (p ≤ 0.02), derived from disruptions to both within-network and whole-brain connectivity (p ≤ 0.049). DMN segregation remained robust (p < 0.0001) despite a disruption to within-network connectivity (p = 0.2). TBILate did not exhibit any change in network segregation or its derivatives (p > 0.05) but did exhibit an increase in FPN-SN connectivity (p = 0.011). These findings provide the typical trajectory of DMN, FPN, and SN development in typically developing adolescents and may suggest the potential long-term impact of SRC on functional network maturation.
