| Abstract: |
| Amateur athletes with a history of three or more concussions were carefully matched (gender, age, education, and sport) with athletes with no prior concussions. ALl completed computerized neuropsychological test battery at preseason and then within 5 days of sustaining a concussion. There were differences between groups in symptom reporting and memory performance. At baseline, athletes with multiple concussions reported more symptoms than athletes with no history of concussion. At approximately 2 days post-injury, athletes with multiple concussions scored significantly lower on memory testing than athletes with a single concussion. Athletes with multiple concussions were 7.7 times more likely to demonstrate a major drop in memory performance than athletes with no previous concussions. |

| Abstract: |
| It is a common assumption in sports medicine that prior history of concussion is predictive of lowered threshold and worse outcome following subsequent concussive injury. The current study was conducted to investigate the relationship between concussion history in high school athletes and the on-field presentation of symptoms following subsequent concussion. |
