| Abstract: |
| The purpose of this study was to examine the validity of ImPACT, a computerized neuropsychological test battery, for measuring attention and processing speed in athletes with concussions. This was accomplished by comparing the computerized testing to a traditional neuropsychological measure, the Symbol Digit Modalities Test. Participants were 72 amateur athletes who were seen within 21 days of sustaining a sports-related concussion. As predicted, the SDMT correlated most highly with the Processing Speed and Reaction Time composites from ImPACT. |

| Normative Data for the ImPACT Composite Scores
A sample of 205 elementary, junior high, and high school students was initially used for this project. Three of these subjects had incomplete test data and were subsequently dropped from the normative sample. The current normative sample consists of 102 boys and 100 girls between the ages of 11 and 14. Multiple analysis of variance (MANOVA) was performed to allow an analysis of performance differences between gender and age across multiple neuropsychological domains. |

| Abstract: |
| Neuropsychological testing is a variable tool in concussion diagnosis and management. ImPACT, a computerized neuropsychological testing program, consists of eight cognitive tasks and a 21-item symptom inventory. ImPACT was used to examine the cognitive performance of 104 concussed athletes at baseline, 2, 7, and 14 days post-injury. Dependent measures included composite scores from the ImPACT computerized test battery, as well as a total symptom score from the Post-Concussion Symptom Scale. |

| Abstract: |
| This study explored the diagnostic utility of the composite scores of Immediate Post-Concussion Assessment and Cognitive Testing and Post Concussion Symptom Scale scores. Recently concussed high school athletes were tested within 72h of sustaining a concussion, and data were compared to non-concussed high school athletes with no history of concussion. |

| Abstract: |
| The relevance of headache to outcome following sports concussion is poorly understood and no studies exist examining this issue. The current study was conducted to investigate whether post-concussion headaches are associated with neurocognitive deficits and/or presence of other post-concussion symptoms at approximately one-week post injury. Study participants included 110 high school athletes who sustained concussion. Concussed athletes were divided into two groups, those reporting no headache at approximately day 7 post-injury and those reporting headaches. Dependent measures included symptom and neurocognitive test results collected via ImPACT, a computerized neuropsychological test battery. |

| Abstract: |
| The purpose of this study was to examine the relation between the subjective report of feeling foggy at one-week post concussion and acute neuropsychological outcome. The outcome variables were derived from a computerized neuropsychological screening battery (ImPACT). Participants were 110 high school students who sustained a sport-related concussion and were evaluated 5-10 days post injury... |
