The purpose of this study was to identify specific symptom and neuropsychological test patterns that might serve as prognostic indicators of recovery in concussed high school football players. The recently proposed simple versus complex concussion classification was examined and specific symptom clusters were identified.
Case-control study.
High school football.
Subjects were 108 recently concussed male high school football athletes between the ages of 13 and 19 (mean, 16.01) years.
Participants were evaluated by utilizing the Immediate Postconcussion Assessment and Cognitive Testing computer-based neurocognitive test battery at before injury and within an average of 2.23 days of injury. All athletes were followed until they met criteria for clinical recovery.
Symptom ratings and neurocognitive test performance.
Both neurocognitive test results and self-reported symptom data had prognostic value in determining time to clinical recovery. Self-reported cognitive decline, Immediate Postconcussion Assessment and Cognitive Testing reaction time, and migraine headache symptoms were associated with longer time to clinical recovery. Overall, these difficulties were predictive of concussions that were retrospectively classified as complex.
Specific symptom clusters and neurocognitive test results may have predictive value to classifying and managing concussions.
本研究旨在确定特定的症状和神经心理学测试模式，这些模式可作为脑震荡高中橄榄球运动员恢复的预后指标。对最近提出的简单与复杂脑震荡分类进行了研究，并确定了特定的症状群。
病例对照研究。
高中橄榄球运动。
受试者为108名最近发生脑震荡的13至19岁（平均16.01岁）的高中男性橄榄球运动员。
在受伤前和受伤后平均2.23天内，使用基于计算机的神经认知测试组合“脑震荡后即刻评估和认知测试”对参与者进行评估。所有运动员均被随访至达到临床恢复标准。
症状评分和神经认知测试表现。
神经认知测试结果和自我报告的症状数据在确定临床恢复时间方面均具有预后价值。自我报告的认知能力下降、脑震荡后即刻评估和认知测试反应时间以及偏头痛症状与临床恢复时间较长相关。总体而言，这些困难可预测那些回顾性分类为复杂脑震荡的情况。
特定的症状群和神经认知测试结果可能对脑震荡的分类和管理具有预测价值。
