The association between self reported history of concussion and current neurocognitive status is controversial. Some football studies suggest that athletes with a history of concussion display cognitive impairment relative to athletes with no history of concussion, but other studies have not been able to reproduce such findings. This study shows that there is no relation between the number of previous self reported episodes of concussion and current cognitive state, directly contradicting the findings of previous research.
