Abstract
BACKGROUND The treatment of patients with headache represents an important part of a neurologist's activity. It requires sufficient training for neurology residents. In France, residents in neurology can complete this training by attending specialized consultations or by participating in a postgraduate training program called "Diplôme Inter-Universitaire Migraine et Céphalées" (DIUMC). OBJECTIVE The objective of this cross-sectional study was to investigate the French residents' knowledge in headache medicine and the impact of different types of training in headache medicine that are available in France. METHODS An anonymous survey was carried out among 548 French residents in neurology. RESULTS The questionnaires of 121 residents (22.1%) were analyzed. Among them, 54.5% (66/121) had no complementary training apart from the internship (Group 1), 21.5% (26/121) had attended only specialized consultations (Group 2), and 24% (29/121) had participated in the DIUMC (Group 3). There was no difference between all groups regarding the knowledge of the prevalence of primary or chronic headaches. There was almost no difference between the groups in the management of episodic migraine. In contrast, the management of tension-type headache and chronic headache was better known by residents of Group 3 than residents of Group 1. In these two diseases, residents of Group 3 offered prophylactic treatment more often. Almost 29% of the residents (35/121) had read the French guidelines for the diagnosis and management of migraine. In Group 3, residents had read them significantly more often (1.6% in Group 1, 38.5% in Group 2 and 62.1% in Group 3, p < 0.001). CONCLUSION This study shows the lack of knowledge among French neurology residents regarding headache medicine. It highlights the interest of specific training programs that could improve the practical and theoretical knowledge of future neurologists.

Abstract
The French Headache Society proposes updated French guidelines for the management of migraine. The first part of these recommendations is focused on the diagnosis and assessment of migraine. First, migraine needs to be precisely diagnosed according to the currently validated criteria of the International Classification of Headache Disorders, 3d version (ICHD-3). Migraine-related disability has to be assessed and we suggest to use the 6 questions of the headache impact test (HIT-6). Then, it is important to check for risk factors and comorbidities increasing the risk to develop chronic migraine, especially frequency of headaches, acute medication overuse and presence of depression. We suggest to use a migraine calendar and the Hospital Anxiety and Depression scale (HAD). It is also necessary to evaluate the efficacy and tolerability of current migraine treatments and we suggest to systematically use the self-administered Migraine Treatment Optimization Questionnaire (M-TOQ) for acute migraine treatment. Finally, a treatment strategy and a follow-up plan have to be proposed. Guidelines for pharmacological and non-pharmacological treatments are presented in the second and third part of the recommendations.

Abstract
Background There is currently a wide therapeutic arsenal for migraine patients, without a single first-line preventive drug and we choose the different available alternatives taking into account comorbidities, national guidelines, previous treatments and personal experiences. Our objective was to evaluate the differences in the use of migraine treatments between neurologists from different countries. Methods This is a multi-centre observational study carried out by neurologists from specialized headache units in seven countries, retrospective with consecutive inclusion of all patients presenting with a migraine diagnosis, over a period of three months. Results A total of 734 patients were recruited but only 600 were considered in the analysis in order to homogenize the patient cohorts from countries: 200 Spain (ES), 100 Italy (IT), 85 Russia (RUS), 80 Germany (DE), 60 Portugal (PT), 45 Poland (PL) and 30 Australia (AU). 85.4 % of patients were women with a mean age of 42.6 ± 11.8 years. Considering previous and current preventive treatment, the order of use was: antidepressants (69.3 %), antiepileptic drugs (54.7 %), beta-blockers and antihypertensive drugs (49.7 %), OnabotulinumtoxinA (44.0 %) and others (36.2 %). Statistically significant differences were found between all pharmacological classes: antidepressants were commonly used in all countries, with the exception of Poland (AU: 76.7 %, IT: 71.0 %, DE: 60.0 %, PL: 31.1 %, PT: 71.7 %, RUS: 70.6 %, ES: 78.5 %; p < 0.0001); antiepileptic drugs were more frequently prescribed in Portugal, Australia and Spain (AU: 73.3 %, IT: 40.0 %, DE: 37.5 %, PL: 48.9 %, PT: 85.0 %, RUS: 29.4 % and ES: 69.0 %; p < 0.0001); beta-blockers and antihypertensive drugs were frequently used in all countries except Italy (AU: 60.0 %, IT: 14.0 %, DE: 53.8 %, PL: 48.9 %, PT: 68.3 %, RUS: 49.4 % and ES: 59.0 %; p < 0.0001); BTX-A were predominately used in Spain, Italy and Australia (AU:56.7 %, IT:58.0 %, DE:20.0 %, PL: 42.2 %, PT: 26.7 %, RUS: 24.7 % and ES: 58.5 %; p < 0.0001) and others were most frequently used in Poland (AU: 0.0 %, IT: 19.0 %, DE: 42.5 %, PL: 95.6 %, PT: 31.7 %, RUS: 3.5 % and ES: 49.5 %; p < 0.0001). If only patients without comorbidities are considered (200/600), statistically differences between countries persist in all preventive treatments. Conclusions There is heterogeneity in the choice of preventive treatment between different countries. Prospective comparative studies of the different oral and subcutaneous alternatives would help to create a global therapeutic algorithm that would guarantee the best option for our patients.

Abstract
Currently many patients with severe migraine do not receive appropriate treatment and are never referred to specialist headache centres. On the other hand, specialist headache centres are frequently attended by patients whose migraines could be managed adequately in the community. One reason for this may be the absence of standardised definitions of migraine severity and control and of a treatment algorithm for orientating difficult-to-treat patients to specialist headache centres. Based on a review of the relevant literature and consensus meetings, proposals have been made for these items. We propose that migraine should be considered severe if headache frequency is at least eight migraine days per month or, if headaches are less frequent, the HIT-6 score is ≥60 or ≥50% of headaches require complete interruption of activity. The proposed definition of migraine control is defined on the basis of appropriate response to acute headache therapy and to preventative therapy. A treatment algorithm is proposed to assess migraine control regularly and to adapt therapy accordingly. These proposals may contribute to developing and testing strategies for management of severe disease with appropriate and effective preventive treatment strategies. With the anticipated introduction of new possibilities for migraine prevention in the near future, the time is ripe for a holistic approach to migraine management.

Abstract
Objectives: To estimate the burden of migraine in the population of French patients identified as specific migraine acute treatment users compared to a control group. Methods: A cross-sectional retrospective analysis was performed on the Echantillon Généraliste des Bénéficiaires claims database, a 1/97 random sample of the French public insurance database. A representative sample of all adults with at least one delivery of triptans, ergot derivatives or acetylsalicylic acid/metoclopramide (all drugs with a specific label in migraine acute treatment - SMAT) in 2014 was selected with a control group matched on age, gender and geographic region. Among triptan users, a sub-group of over-users was defined according to their level of triptan uptake expressed in defined daily doses (DDD - a standard daily dose of treatment of acute migraine) per month over 3 months and more, was also compared with controls. The cost analysis was performed in a societal perspective for direct costs. Sick leave indirect costs were estimated using the human capital approach. Results: In total 8639 SMAT users (mean age: 44.6 years; 78.7% women) were selected representing a crude prevalence rate of 1.7%. The annual per capita total healthcare expenditures were higher by €280 in this group compared to controls (€2463 vs. €2183). Triptans contributed 47.8% to this extra cost. They used significantly (p < .0001) more frequently than controls antidepressants (20.8% vs. 11.0%), anxiolytics (29.4% vs. 18.8%) and analgesics (53.8% vs. 35.8%). The per capita annual productivity loss associated with sick leave was higher by €295 (€1712 vs. €1417). Among triptan users, there were 2.9% over-users. This last group was characterized by substantially higher per capita annual extra direct (+ €1805) and indirect costs (productivity loss +€706) compared to controls. Conclusions: Due to its high prevalence, migraine costs generate a significant societal burden. The group of over-users concentrates high per capita direct and indirect costs.

Abstract
BACKGROUND Migraine, especially chronic migraine (CM), causes substantial disability; however, health care utilization has not been well characterized among patients receiving different migraine prophylactic treatments. METHODS Using a large, US-based, health care claims database, headache-related health care utilization was evaluated among adults with CM treated with onabotulinumtoxinA or oral migraine prophylactic medications (OMPMs). Headache-related health care utilization was assessed at six, nine, and 12 months pre- and post-treatment. The primary endpoint was the difference between pre- and post-index headache-related health care utilization. A logistic regression model was created to test the difference between onabotulinumtoxinA and OMPM-treated groups for headache-related emergency department (ED) visits and hospitalizations. RESULTS Baseline characteristics were comparable between groups. The proportion of patients with ED visits or hospitalizations for a headache-related event decreased after starting onabotulinumtoxinA, but increased after starting an OMPM, for all three cohorts. Regression analyses showed that the odds of having a headache-related ED visit were 21%, 20%, and 19% lower and hospitalization were 47%, 48%, and 56% lower for the onabotulinumtoxinA group compared to the OMPM group for the six-month, nine-month, and 12-month post-index periods, respectively. CONCLUSIONS When compared with similar patients who initiated treatment with OMPM, onabotulinumtoxinA was associated with a significantly lower likelihood of headache-related ED visits and hospitalizations.

Abstract
INTRODUCTION The hypothesis that migraine pain is caused by vasodilation has been challenged by clinical and experimental evidence. STATE OF ART The most convincing arguments against the vascular hypothesis come from neuroimaging data. Magnetic resonance imaging studies show that spontaneous migraine attacks are not accompanied by extracranial vasodilation, and by only slight dilation of the intracranial arteries. Pharmacologically-induced migraine attacks also provide further evidence against the role of vasodilation in migraine. Vasodilators such as sildenafil and nitroglycerine trigger attacks without dilation of the middle cerebral artery diameter, whereas VIP (vasoactive intestinal peptide) markedly dilates intra- and extracranial arteries but does not induce migraine attacks. Clinical studies also show a lack of correspondence between the subjective experience of throbbing headache and the arterial pulse. Moreover, many acute anti-migraine agents are not vasoconstrictors. PERSPECTIVES Further studies are necessary to clarify the mechanisms of migraine headache generation. CONCLUSIONS Contrary to a longstanding and widespread belief, vasodilatation is neither sufficient nor necessary to cause migraine headache and is probably an epiphenomenon.
