title: The prevalence of premonitory symptoms in migraine: a questionnaire study in 461 patients.
abstract: Migraine attacks are often preceded by premonitory symptoms. Prevalence rates of migraine patients reporting one or more premonitory symptoms show considerable variability and rates range between 12% and 79%. Sources of variability might be differences in study population or research design. Using a questionnaire, we retrospectively studied the prevalence of 12 predefined premonitory symptoms in a clinic-based population. Of 461 migraine patients, 374 (81%) responded. At least one premonitory symptom was reported by 86.9% and 71.1% reported two or more. The most frequently reported premonitory symptoms were fatigue (46.5%), phonophobia (36.4%) and yawning (35.8%). The mean number of premonitory symptoms per person was 3.2 (+/- 2.5). Women reported 3.3 premonitory symptoms compared with 2.5 symptoms in men (P = 0.01). Age, education, migraine subtype (with or without aura) and mean attack frequency had no effect on the mean number of symptoms per individual. In conclusion, premonitory symptoms are frequently reported by migraine patients. Sensitivity and specificity of premonitory symptoms for migraine need to be assessed using prospective methods.
