Concussion history and neuropsychological baseline testing in collegiate football athletes
While there has been ample research examining the relationship between an acute concussion on immediate neuropsychological performance, very little research has examined the relationship between lifetime concussion history with current neuropsychological performance. We collected preseason neuropsychological test performance (ImPACT) and a detailed lifetime concussion history questionnaire from 71 UCF football players. Stepwise linear regressions were conducted for each of the five ImPACT domain scores for the 18 participants that reported at least one lifetime concussion. The regressions used the following four concussion history predictors: total number of lifetime concussions, length of time between last concussion and lmPACT testing, severity of worst concussion, and severity of most recent concussion. Results revealed that only one ImpACT domain score had at least one predictor enter the model. For the domain of visual memory, the predictor of length of time between last concussion and ImPACT testing entered the model (and only that predictor),P = 4.07, t(l7) = 2.78,p = .01, R1 = .33, as a shorter length of time between the last concussion and the preseason testing related to lower performance on the visual memory tests. Many athletes and clinicians assume that the cognitive effects of a concussion are relatively brief in duration. However, the results of this study suggest that, at least for visual memory, these effects may last for several years following a concussion. The correlational design of this study precludes drawing conclusions about the causal direction of this relationship, but future longitudinal research may be able to clarify this important preliminary finding.
