Abstract

Recent interest in cognitive processing in migraine has been based on the assumption that cortical hyperexcitability in migraine with aura may manifest itself in the form of response time advantages in migraine as compared to controls. The study reported here attempted to replicate and extend the findings of Wray and colleagues (Brain 1995;118:25–35). Using identical cognitive tasks, three experiments failed to find differences between migraine with aura patients and controls: furthermore, an additional group of patients without aura were also statistically indistinguishable from controls with respect to response times. Error rates were consistently high across experiments, indicating that subjects were responding at or near chance levels. These findings cast doubt on the utility of straightforward cognitive psychological methods for the study of cortical hyperexcitability in migraine. Some theoretical difficulties concerning the interpretation of response times in the context of migraine pathophysiology are discussed.
