title: Chronic daily headache in French children and adolescents.
abstract: To characterize the clinical profile, comorbidity and aggravating factors, and outcomes, a consecutive series of 34 French children and adolescents with chronic daily headache was studied. Of 206 referred over an inclusive interval of 2 years for the evaluation of headaches, 34 merited a diagnosis of chronic daily headache, which was defined as persistent or daily headaches of at least 3 months in duration. The overwhelming majority were female (61.8%), with a mean age at diagnosis of 10.5+/-3.1 years (range, 2.9-14.8 years). According to the Silberstein-Lipton criteria, transformed migraine was the etiology in 61.8%, whereas according to the second edition of the International Classification of Headache Disorders, chronic migraine accounted for 50% of cases. Stressors were recognized in 82%. Analgesic abuse was evident in 52.9%. Of the 29 for whom follow-up information was available, headaches resolved or greatly improved in 93.1%. Children and adolescents with chronic daily headache are thus a small subset of children with headache seen in general ambulatory practice. They tend to be girls in the midteen years experiencing a transformed migraine complicated by analgesic abuse, suggesting potential preventability. Simple measures, which can include reassurance and analgesia education, can be expected to result in improvement and eventual resolution of headache symptoms.
