INTRODUCTION: Specific problems occur in clinical treatment trials for migraine with aura that differ from those encountered in treatment trials for migraine without aura. DISCUSSION: Based on our experience with four such trials, we point to a number of possible solutions and outline areas for future inquiry. We make recommendations about subject selection; the choice, definition and assessment of outcome measures; optimal treatments in relation to aura and headache; and we provide samples of study report forms used to record occurrence of aura and headache in this population.
