Randomized Controlled Trial Multicenter Study Comparative Study
Frovatriptan versus zolmitriptan for the acute treatment of migraine with aura: a subgroup analysis of a double-blind, randomized, multicenter, Italian study.
Migraine with aura affects ~20-30 % of migraineurs and it is much less common than migraine without aura. The aim of this study was to compare the efficacy of frovatriptan 2.5 mg and zolmitriptan 2.5 mg in the treatment of migraine with aura. Analysis was carried out in a subset of 18 subjects with migraine with aura (HIS criteria) out of the 107 enrolled in a multicenter, randomized, double-blind, cross-over study. ⋯ The rate of pain-free episodes at 2 h was significantly (p < 0.05) larger under frovatriptan (45.8 %) than under zolmitriptan (16.7 %). Pain free at 4 h, pain relief at 2 and 4 h and recurrent episodes were similar between the two treatments, while sustained pain-free episode was significantly (p < 0.05) more frequent during frovatriptan treatment (33.3 vs. 8.3 % zolmitriptan). Our study suggests that frovatriptan is superior to zolmitriptan in the immediate treatment of patients with migraine with aura, and it is capable of maintaining its acute analgesic effect over 48 h.

Patients with chronic migraine developing medication-overuse headache (MOH) show dependency-like behaviors such as loss of control over analgesics despite adverse consequences on headaches, high rates of relapse after withdrawal from symptomatic medications, and compromised social functioning. Neuroimaging research suggests a common pathophysiology between substance-use disorders and MOH, which involves functional alterations in fronto-striatal networks, particularly in the orbitofrontal region of prefrontal cortex. These findings could explain the impaired decision-making observed in substance-use disorders. ⋯ Looking at these shared neurocognitive features, our results suggest that MOH could belong to the addiction spectrum. Fronto-striatal dysfunction could be a premorbid psychobiological condition of vulnerability explaining the clinical onset of medication overuse and recurrent relapses. We propose that IGT could be used to identify chronic migraine patients with higher risk for medication overuse and relapse.

Although migraine (MH) and tension type headache (TTH) are the most common and important causes of recurrent headache in adolescents, they are poorly understood and not recognized by parents and teachers, delaying the first physician evaluation for correct diagnosis and management. The purpose of this study is to assess the knowledge about headache impact among the students of a Communication Private High School in Rimini city, and to evaluate the main different types of headaches interfering with school and social day activities. ⋯ Out of the 60 students, 84 % experienced recurrent headache during the last 12 months. 79 % were females, aged 17-20 years; a family history was present in 74 % of headache students, in the maternal line; 45 % of subjects were identified as having MH and 27 % TTH; 25 % had morning headache and 20 % in the afternoon; fatigue, emotional stress and lack of sleep were the main trigger factors for headache, respectively in 86, 50 and 50 % of students; 92 % of headache students could not follow the lessons, could not participate in exercises and physical activity because of the headache; none had consulted a medical doctor and the 90 % of all students had never read, listened or watched television about headache. This study remarks on the need to promote headache educational programs, starting from high school, to increase communication between teachers-family-physician and patient-adolescents, with the goal to have an early appropriate therapeutic intervention, improvement of the quality of life and to prevent long-term headache disease in the adult age.
