Chronic daily headache in children and adolescents: science and conjecture

Abstract

SUMMARY Chronic daily headache comprises a group of headache disorders in which headaches occur almost daily or continuously over several months. Although chronic daily headache is one of the most common chronic pain disorders in pediatrics, data on pathophysiological mechanisms and relative efficacy of treatments remain sparse. In this review, we aim to provide contemporary information on classification, epidemiology, etiology and treatment of pediatric chronic daily headache based on extant empirical data when available, or general consensus in the field when not.
