The prevalence of premonitory symptoms in paediatric migraine: a questionnaire study in 103 children and adolescents

The prevalence and characterization of premonitory symptoms have not been rigorously studied in children and adolescents. Using a questionnaire, we retrospectively studied the prevalence of 15 predefined premonitory symptoms in a clinic-based population. In 103 children and adolescents fulfilling the International Classification of Headache Disorders, 2nd edn criteria for paediatric migraine, at least one premonitory symptom was reported by 69 (67%). The most frequently reported premonitory symptoms were face changes, fatigue and irritability. The mean number of premonitory symptoms reported per subject was 1.8 (median 2.2). Age, migraine subtype (with or without aura) and mean attack frequency per month had no effect on the mean number of premonitory symptoms reported per subject. In conclusion, premonitory symptoms are frequently reported by children and adolescents with migraine. Face changes seem to be a premonitory symptom peculiar to paediatric migraine.
