Studies on executive function & attention post-concussion Extent of injury in developing brains (adolescents) compared to adults? Greater risk of subsequent injury w/ premature return to sport
Subtle deficits can persist, despite self report Decline in academic performance Body movement, gait Task-shifting
Recovery N=134 High School Male Football Athletes WEEK 1 WEEK 2WEEK 3 WEEK 4 WEEK 5 40%RECOVERED 60%RECOVERED 80%RECOVERED Collins et al., 2006, Neurosurgery
Cognitive effects of one season of head impacts in a cohort of collegiate contact sport athletes: What lifestyle factors might delay cognitive decline/ dementia?; McAllister et al. (assigned reading)
Millions suffer brain injury each year Many are sub-concussive injuries Test effect of repetitive traumas over season of collegiate sports 214 football & hockey players 45 non-contact sport players
ImPACT, neuropsychological, cognitive testing Pre & post season Head impacts measured via HIT helmets Rotational & linear acceleration Location, force of impacts Average 469 impacts
Significantly higher % of contact athletes performed below predicted postseason score Subgroup w/ cognitive impact - higher magnitudes/frequencies No differences pre-season Suggests lack of residual effects Confounds?
