- W4387053048 abstract "Electroencephalography (EEG) is an effective neuroimaging tool that measures spatial and temporal alterations in brain electric activity and may provide mechanistic information about concussion diagnosis and recovery. We aimed to use resting-state EEG (rs-EEG), and a battery of cognitive function tests, to examine the cognitive and functional differences and associations between concussed and non-concussed individuals at baseline and over a 3-month follow up period. Establishing these associations may provide evidence leveraging existing methods that promote recovery post-concussion. PURPOSE: To examine the cross-sectional and longitudinal associations between rs-EEG and cognitive function in concussed versus non-concussed athletes. METHODS: Baseline measures of cognitive function and rs-EEG were collected from 72 Division-1 student-athletes (20.04 ± 1.48 yrs.), of which 24 had an acute concussion diagnosed by trained athletic trainers. Concussed participants repeated baseline measures within 7 days of initial diagnosis and follow-up measures were collected at 1- and 3-month periods. Analyses were conducted using logistic and linear regression, controlling for age and sex. RESULTS: At baseline, concussed athletes (N = 21) scored significantly lower in symbol digit modality (β = 0.05; 95% CI = 0.006, 0.122; p = 0.04) compared to non-concussed (N = 47). Relative delta (β = -3.48; 95% CI = -7.14, -0.33; p = 0.04) and theta (β = -14.4; 95% CI = -28.5, -1.75; p = 0.03) power in posterior electrodes were also significantly increased in concussed athletes (N = 24) compared to non-concussed (N = 48). In the concussed group, lower baseline relative delta (N = 15; β = 0.55; p = 0.03) and theta (N = 15; β = 0.60; p = 0.02) power in posterior electrodes were associated with greater 1-month improvement in trail-making-part A performance. CONCLUSION: These exploratory findings provide preliminary evidence of rs-EEG measures, coupled with cognitive function tests, to predict longitudinal gains in cognitive function post-concussion." @default.
