Depression and neurocognitive performance after concussion among male and female high school and collegiate athletes.
OBJECTIVES To prospect ively examine the relationship of sport-related concussion with depression and neurocognitive performance and symptoms among male and female high school and college athletes . A secondary objective was to explore age and sex differences . DESIGN Pretest , multiple posttest , repeated- measures design . SETTING Laboratory . PARTICIPANTS High school and collegiate athletes ( N=75 ) with a diagnosed concussion . INTERVENTIONS Not applicable . MAIN OUTCOME MEASURES  Beck Depression Inventory-II and computerized neurocognitive test battery ( Immediate Post-concussion Assessment and Cognitive Test )  , which includes concussion symptoms ( Post-concussion Symptom Scale ) at baseline and at 2 , 7 , and 14 days postinjury . RESULTS Concussed athletes exhibited significantly higher levels of depression from baseline at 2 days ( P≤.001 ) , 7 days ( P=.006 ) , and 14 days postconcussion ( P=.04 ) . Collegiate athletes demonstrated a significant increase in depression at 14 days postconcussion than did high school athletes ( P=.03 ) . There were no sex differences in depression levels . Neurocognitive decrements at 14 days were supported for reaction time ( P=.001 ) and visual memory ( P=.001 ) . Somatic depression at 7 days postconcussion was related to slower reaction time at 7 days postconcussion . Somatic depression at 14 days postinjury was related to lower visual memory scores at 14 days postinjury . CONCLUSIONS Although not clinical ly significant , athletes experienced increased depression scores up to 14 days after concussion that coincided with neurocognitive decrements in reaction time and visual memory . Somatic depression appears to be most salient with regard to lower neurocognitive performance . Mood assessment s after concussion are warranted to help monitor and enhance recovery
