Do children and adolescents have chronic daily headaches? Yes!

Chronic daily headache in children and adolescents: science and conjecture

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.

Favorable outcome of early treatment of new onset child and adolescent migraine-implications for disease modification

There is evidence that the prevalence of migraine in children and adolescents may be increasing. Current theories of migraine pathophysiology in adults suggest activation of central cortical and brainstem pathways in conjunction with the peripheral trigeminovascular system, which ultimately results in release of neuropeptides, facilitation of central pain pathways, neurogenic inflammation surrounding peripheral vessels, and vasodilatation. Although several risk factors for frequent episodic, chronic, and refractory migraine have been identified, the causes of migraine progression are not known. Migraine pathophysiology has not been fully evaluated in children. In this review, we will first discuss the evidence that early therapeutic interventions in the child or adolescent new onset migraineur, may halt or limit progression and disability. We will then review the evidence suggesting that many adults with chronic or refractory migraine developed their migraine as children or adolescents and may not have been treated adequately with migraine-specific therapy. Finally, we will show that early, appropriate and optimal treatment of migraine during childhood and adolescence may result in disease modification and prevent progression of this disease.

Chronic daily headaches in children and adolescents

Headaches, which are common in children and adolescents, represent a significant portion of patient complaints in a child neurology practice. Patients with episodic headaches, such as migraines with interval-free periods, and patients with chronic daily headaches with very few headache-free days, are often evaluated and treated differently from each other. The evolution of the classification of chronic daily headache has aided epidemiologic efforts. The disorder can be primary or related to other neurologic or systemic conditions. Comorbid conditions should be identified, and the contributing variables in the child's social, emotional, medical, and educational arenas should be assessed. The level of disability in terms of school attendance and function can help clinicians determine to what extent and how aggressively to treat these children. Rescue medications, such as barbiturates and narcotics, which can cause worsening of headaches, should be avoided.
