Critical analysis of diagnostic criteria (ICHD-3 beta) about migraine in childhood and adolescence.

OBJECTIVE The objective of this study was to prospectively evaluate the International Classification of Headache Disorders I (ICHD-I) diagnostic criteria for migraine in children and adolescents. METHODS 150 pain diaries were analyzed during an initial consultation. The duration of migraine headache attacks were divided into 2 groups: Group I, for attacks lasting > 2 hours, and Group II, for attacks lasting < 2 hours.The two groups were statistically compared using Fisher's exact test (p < 0.05). RESULTS In this study, 51(34%) subjects were male and 99 (66%) were female, aged 7-15 years. Fisher's exact test demonstrated that the ICHD-3 beta had a 58% sensitivity for Group I diagnoses and a 94% sensitivity for Group II diagnoses (p < 0.001). CONCLUSION The current ICHD-3 beta classification improves and advances migraine diagnosis in children and adolescents; however, more research is needed to identify additional characteristics of headache in this age group.
