During the baseline period, while the patient is without any migraine symptoms and feeling well (interictal period), three practice trials on the MEWT will be performed and a fourth MEWT trial will be taken with the score recorded for a neuropsychological baseline. When the patient experiences a migraine headache, the patient will rate headache severity and associated symptoms and then take Treximet or matching placebo. The patient will repeat headache and associated symptom checklist and the MEWT at 1 and 2 hours after treatment. Rescue medication will be allowed at 2 hours for those patients who require it.
