The Mental Efficacy Workload Test (MEWT) is a computerized battery that is designed to be an efficient and accurate measure of cognition during migraine headache. Treximet is a new migraine treatment recently FDA approved for the treatment for the relief of acute migraine that may be effective for the cognitive symptoms for migraine patients who have a history of cognitive dysfunction during a migraine headache. The primary efficacy parameter is to evaluate the effectiveness of treatment with Treximet versus placebo in patients with acute migraine headache measuring neuropsychological function using the MEWT during the migraine and comparing that score with a prior MEWT score when the patient had no migraine symptoms. A double blind, placebo-controlled, crossover study was chosen so that each patient may be her or his own control.
