title: Selection of patients--critical aspects.
abstract: Proper selection of patients is the most critical aspect in designing clinical trials in migraine research. We establish specific research diagnostic criteria for the definition of migraine. Additional factors in patient selection, migraine frequency, duration, medications and previous treatments, are reviewed. Exclusion criteria and the mixed headache syndrome patient are discussed.
