Sports Related Concussion (SRC) is a mild form of head
trauma, which has been shown to primarily affect brain
function rather than structure. In the current study, we
used a N-Back fMRI experiment to compare the fMRI
results in the acute and delayed phases of recovery from
SRC with those from matched normal controls. Our results
show that the acute phase of SRC reduces BOLD activation
in both vigilance and working memory tasks. It also
suggests that SRC induced impairment may largely recover
after a relatively short period of time.
