The aim of this study is to characterize the
differential long-term effects of sub-concussive brain
injury on high school football athletes with and without
a history of concussion (HoC and NoHoC). For this
purpose, group differences in various graph-theoretical
network measures were computed to characterize their
networks segregation, integration and resilience
properties. HoC athletes exhibited significantly lower
segregation than NoHoC athletes. Reduced segregation is
expected with aging over healthy adult life span, thus
suggesting a relatively faster aging brain for HoC
athletes. HoC athletes also exhibited lower
assortativity values suggesting relatively more
vulnerable highly-connected brain regions.
