Juvenile Fibromyalgia and Headache Comorbidity in Children and Adolescents: A Literature Review

Juvenile fibromyalgia (JFM) is a chronic pain syndrome with onset in developmental age, characterized by widespread mus- culoskeletal pain associated with other neurological or nonneurological symptoms. Headache is one of the most frequent comorbid conditions with JFM, but this association is still poorly studied in the juvenile population. The literature review was conducted searching through PubMed, Scopus, and Web of Science with a combination of the following free-text terms: “fibromyalgia,” “juvenile fibromyalgia,” “headache,” “primary headache,” “migraine,” “children,” “adolescents,” and “comor- bidity.” The research resulted only in two specific studies regarding comorbidity JFM + Juvenile Headache (JH). From each study, we extracted data about sample features, clinical characteristics of both JFM and PH, and assessment tools. The clinical approach to JFM and JH should include a complete examination of the main causes of comorbid diseases, thus improving the therapeutic approach to the patient in developmental age.
