Aim: To describe the natural history, evaluate the long-term prognosis, and identify predictors of a favorable outcome of childhood migraines in a cohort of children who had been diagnosed with migraine 25 years before.
Methods: One hundred eighteen children with headache (ages 2 to 15), observed in a headache outpatient clinic of a University Hospital in 1994, by one of the authors, were revaluated in 2019/2020 by a standardized telephone interview specifying headache characteristics, treatment, precipitants, and family history. Headache diagnosis at follow-up was based on ID-Migraine and confirmed by a semistructured interview.
Results: Revaluation was achieved for 88 (75%) patients (43 with migraine), 47 women and age average 41.2 ± 3.2. Over the follow-up (average 25.5 years), 33% of the patients had experienced remission, 41% maintained the same diagnosis, and 26% evolved into a different headache. Sixty six percent reported an improvement. Only eight patients were attending regular consultations because of headache. Male sex came out as the only predictor of a favorable outcome.
Conclusion: Most patients (66%) with pediatric headache continue to experience headache although reporting a significant improvement. Boys tended to remit more often than girls. This data suggests that age, genetics, and hormonal factors may play an important role in migraine phenotypic expression.
