Abstract: BACKGROUND: The French Recommendations for Clinical Practice: Diagnosis and Therapy of Migraine are guidelines concerning the overall management of patients with migraine, including diagnostic and therapeutic strategies and assessment of disability. OBJECTIVE: This article summarizes the guidelines as they apply to adults and children, and proposes future direction for steps toward optimal treatment of migraine in patients in France. METHODS: The recommendations were categorized into 3 levels of proof (A-C) according to the National Agency for Accreditation and Evaluation in Health (ANAES) methodology and were based on a professional consensus reached among members of the Working Group and the Guidelines Review Group of the ANAES. RESULTS: The International Headache Society diagnostic criteria for migraine should be used in routine clinical practice. Recommended agents for the treatment of migraine in adults include nonsteroidal anti-inflammatory drugs, acetylsalicylic acid (ASA) monotherapy or in combination with metoclopramide, acetaminophen monotherapy, triptans, ergotamine tartrate, and dihydroergotamine mesylate. Patients should use the medication as early as possible after the onset of migraine headache. For migraine prophylaxis in adults, the following can be used: propranolol, metoprolol, oxetorone, or amitriptyline as first-line treatment, and pizotifen, flunarizine, valproate sodium, or topiramate as second-line treatment. Migraine in children can be distinguished from that in adults by shorter duration (2-48 hours in children aged <15 years), more frequent bilateral localization, frequent predominant gastrointestinal disturbances, and frequent pallor hailing the onset of the attack. The following drugs are recommended in children and adolescents: ibuprofen in children aged >6 months, diclofenac in children weighing >16 kg, naproxen in children aged >6 years or weighing >25 kg, ASA alone or in combination with metoclopramide, acetaminophen alone or in combination with metoclopramide, and ergotamine tartrate in children aged >10 years. CONCLUSIONS: These guidelines are intended to help general practitioners to manage migraine patients according to the rules of evidence-based medicine.

Abstract: General practitioners (GPs) play a pivotal role in managing migraine and ensuring that patients have a positive first experience when seeking treatment. A large proportion of migraineurs do not consult a GP, preferring to rely on over-the-counter remedies to reduce pain and disability. For those who do consult, receiving a satisfactory outcome at their first consultation is important for ensuring subsequent effective management of their migraine. If patient expectations are not met at their first visit (prescribed treatment is ineffective or GP does not empathize with their suffering), patients may not return for further consultation. There remains a need to improve migraine diagnosis and treatment, and GPs require continuing medical education and neurologist support to ensure that they are providing the best migraine treatments and outcomes. More widespread use of diagnostic tools, standardized management guidelines and individualized treatment regimens will help GPs successfully manage both migraine symptoms and patient expectations.

Abstract: The discovery of the triptans (selective serotonin agonists 5HT(1B/1D), with 7 compounds (almotriptan, eletriptan, frovatriptan, naratriptan, rizatriptan, sumatriptan, zolmitriptan) soon available (5 in France: sumatriptan, naratriptan, eletriptan, zolmitriptan and almotriptan), was a considerable step forward in the acute treatment of migraine. Although randomized clinical studies have demonstrated their significant efficacy, triptans have still to be accepted into the clinical practice of some prescribing practitioners. Rather than attempting to highlight clinically insignificant differences between the triptans, efforts need to be focused on the optimal use of these drugs in clinical practice. This review therefore aims at answering questions related to the efficacy of triptans, recurrence of attacks after use, safety and tolerability, drug interactions and the cost of triptans in clinical use. Triptans are effective and well-tolerated drugs in the acute treatment of migraine attacks, and are the most cost-effective migraine therapy in patients with severe symptoms. Triptans should therefore be considered as first-line therapy in a stratified strategy, ensuring 'right treatment first time' for patients with severe migraine. Moreover, although very few studies have been conducted to date, clinical experience shows that a non-responder to one triptan may well benefit from another triptan, or even the same compound via a different route of administration.

Abstract: A minority of migraine sufferers are diagnosed and treated and medical consultation rates are low even among those aware of their condition. Despite guidelines recommending the use of triptans, there are high rates of usage of nonspecific treatments, mainly simple analgesics, coupled with low prevalence of triptan use. Consequently, many individuals with migraine are not receiving the kind of treatment that would meet their expectations and leave them satisfied. For patients, the most important attributes of acute migraine treatment are complete freedom from pain, rapid onset of action, no recurrence and absence of side effects. More widespread use of triptans would have the potential to improve outcomes and increase patient satisfaction, leading to a better migraine-related quality of life. In choosing among triptans, physicians need to match individual patients' needs and wants with the attributes of the particular triptans, taking into account a medication's complete profile of efficacy, consistency and tolerability, and using information from meta-analyses and modelling to ensure evidenced-based, patient-oriented decision-making.

Abstract: The 2004 International Headache Society (IHS) classification of headache disorders introduced the new category of probable migraine defined by the existence of all but one of typical migraine criteria. FRAMIG 3, the first nationwide population-based survey performed in France using the 2004 IHS classification, assessed the prevalence of probable migraine and compared its features and management with those of strict migraine. Of a representative sample of 10,532 adult subjects interviewed, 1179 subjects (11.2%) were diagnosed as having strict migraine and 1066 (10.1%) as having probable migraine. The criterion most frequently missing was typical headache duration (4-72 h) and most subjects with probable headache had shorter average headache duration. Migraine severity and disability, although lower than those noted in subjects with strict migraine, were significant in subjects with probable migraine and quality of life impairment was identical among the two groups of migraine sufferers. Strict and probable migraine, which have similar prevalence and impact on migraine subjects, deserve similar medical and therapeutic management.

Abstract: FRAMIG 2000 is a population-based survey of medical and therapeutic management of migraine in France. A total of 312 migraine sufferers were first identified from a representative sample of 4689 adult subjects using a validated questionnaire based on the IHS migraine diagnostic criteria and administered by telephone. Subjects were then interviewed using a branching questionnaire and a computer-assisted interview technique. Although 80% were self-aware of their migrainous state, 82% of migraine sufferers had no medical follow-up for migraine. The proportion of migraine sufferers who did not consult decreased slightly with increasing migraine-related disability (from 87% for subjects in MIDAS grade I to 68% for those in MIDAS grade IV). Migraine sufferers declared to effectively control only four attacks out of 10 after the first intake of the usual treatment. Only 6% of subjects in the survey received a prophylactic treatment for migraine whereas 22% were in MIDAS grade III or IV. These data show that the burden of migraine does not result from a deficit in diagnosis but instead from a deficit in patient information on the proper use of current effective treatments of migraine.

Abstract: INTRODUCTION: Seglor capsules, a unique modified-release formulation of dihydroergotamine mesilate, have long been in clinical use in France for migraine prophylaxis. The aim of the PROMISE (PROphylaxis of MIgraine with SEglor) study was to establish the efficacy and tolerability of Seglor in the prevention of migraine in a general practice setting. METHODS: The PROMISE study was a double blind, placebo-controlled, parallel-group study carried out in primary care practice. It included 363 migraine patients treated with Seglor or placebo for 5 months after a 1-month placebo run-in phase. RESULTS: Migraine attack frequency (primary efficacy criterion) decreased markedly in the two treatment groups so that the difference in favour of Seglor did not reach statistical significance. However, most secondary outcome measures (duration of single attack, total duration of attacks over 1 month, consumption of mild opiate analgesics, subjective improvement) improved to a significantly greater degree in patients receiving Seglor than in those receiving placebo. In the 84.5% of patients who had impaired quality of life at entry, the percentage of reduction in attack frequency and most other efficacy measures showed significant improvement with Seglor. The safety profile for Seglor was comparable to that of placebo. CONCLUSION: These results support the effectiveness of Seglor in patients with migraine-related quality-of-life impairment. The findings of the PROMISE study also suggest that patients' quality of life should be assessed systematically before initiating a preventive treatment for migraine.

Abstract: BACKGROUND: Pharmacy personnel are supposed to be well informed of recommendations for proper migraine management, but their easy access to medicines may favor self-medication and promote medication overuse for those with frequent migraine attacks. OBJECTIVE: The main objective of the COTA survey was to investigate migraine management by pharmacy personnel who considered themselves as migraineurs. METHODS: Out of 22,000 pharmacies currently open in France, a questionnaire was proposed to a random sample of approximately 4000 pharmacies with at least 1 self-considered migraineur in the pharmacy staff who accepted to complete and return the questionnaire. The reality of migraine was assessed by the study questionnaire according to the International Classification of Headache Disorders, 2nd edition (ICHD-II) criteria. In addition, the study questionnaire inquired about subjects' demographics, headache characteristics, consumption of medications for headaches, subjects' satisfaction with the usual treatment of headaches and treatment effectiveness. Medication overuse was defined in terms of treatment days per month during the previous 3 months according to the ICHD-II criteria for medication overuse headache. RESULTS: Some 74% of the 3326 participating pharmacies with a self-considered migraine subject among their staff actually returned the survey questionnaire. Using the ICHD-II criteria, migraine was confirmed in 85% of participating subjects, of whom 38% were under medical supervision and had asked for a prescription, and 27% used recommended medications. The treatment used was truly effective for only 31% of migraineurs. Medication overuse was observed in 21% of all participating subjects, mostly migraineurs. Most migraineurs with medication overuse (81%) used nonrecommended treatments. CONCLUSIONS: Considering their pivotal role in advising migraine patients who seek their help with self-management, migraine education of pharmacy personnel about proper migraine management should be reinforced.

Abstract: The objective of this analysis was to describe psychological and cognitive variables in subjects with migraine and to identify those associated with chronicity. Data were collected from 10 000 subjects during face-to-face interview. Subjects with episodic migraine (n = 1127) or chronic daily headache (n = 407) with migrainous features were identified using an algorithm based on the International Classification of Headache Disorders, 2nd edn classification. Data on headache impact was obtained with the Headache Impact Test-6, on psychological distress with the Hospital Anxiety and Depression Scale, on coping with the Coping Strategy Questionnaire catastrophizing score and the Brief COPE inventory, on illness perception with the Brief Illness Perception Questionnaire and on locus of control. Psychological variables associated with chronicity include perceived headache impact, psychological distress, the use of catastrophizing and avoidance coping strategies and an externalized locus of control. In conclusion, maladaptive coping strategies should be taken into account in the management of patients with migraine. Longitudinal studies will be necessary to address the causality of the relationship observed.

Abstract: The objectives of the SMILE study were to assess anxiety, stress, depression, functional impact and coping behaviours in migraine patients consulting in primary care in France. General practitioners (n = 1467) and 83 neurologists included 5417 consulting migraine patients. Of these patients, 67% were found anxious, of whom 59% were also depressive. Patients with both anxiety and depressive dimensions showed a profile similar to that of chronic migraine patients (severe attacks, poor treatment effectiveness and pronounced stress, functional impact and maladaptive behaviours). A quantitative progression in the levels of stress, maladaptive coping behaviours and functional impact was noted from patients with neither dimension to those with both anxious and depressive dimensions. Stress and maladaptive coping strategies were found to be major determinants of anxiety. Anxious and depressive dimensions were associated with elevated consumption of acute treatments for migraine and low treatment effectiveness. Stress and anxiety should be looked for carefully in migraine patients.

Abstract: OBJECTIVE: The aim of this study was to assess behavioral dependence on migraine abortive drugs in medication-overuse headache (MOH) patients and identify the predisposing factors. BACKGROUND: It is common occurrence that MOH patients relapse after medication withdrawal. Behavioral determinants of medication overuse should therefore be identified in MOH patients. METHODS: This was a cross-sectional, multicenter study that included 247 MOH patients (according to International Classification of Headache Disorders, 2nd edition criteria) consulting in French headache specialty centers. Face-to-face interviews were conducted by senior neurologists using a structured questionnaire including the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for the evaluation of dependence, Hospital Anxiety and Depression Scale for the evaluation of anxiety and depression, and 6-item short-form Headache Impact Test scale for the determination of functional impact. RESULTS: Most MOH patients had pre-existing primary migraine (87.4%) and current migraine-type headaches (83.0%). Treatments overused included triptans (45.8%), opioid analgesics alone or in combination (43.3% of patients), and analgesics (27.9%). Nonmigraine abortive substances (tobacco, caffeine, sedatives/anxiolytics) were overused by 13.8% of patients. Two-thirds of MOH patients (66.8%) were considered dependent on acute treatments of headaches according to the DSM-IV criteria. Most dependent MOH patients had migraine as pre-existing primary headache (85.7%) and current migraine-type headaches (87.9%), and most of them overused opioid analgesics. More dependent than nondependent MOH patients were dependent on psychoactive substances (17.6% vs 6.1%). Multivariate logistic analysis indicated that risk factors of dependence on acute treatments of headaches pertained both to the underlying disease (history of migraine, unilateral headaches) and to drug addiction (opioid overuse, previous withdrawal). Affective symptoms did not appear among the predictive factors of dependence. CONCLUSION: In some cases, MOH thus appears to belong to the spectrum of addictive behaviors. In clinical practice, behavioral management of MOH should be undertaken besides pharmacological management.

Abstract: The SMILE study was conducted among migraine patients consulting in primary care in France. The first phase aimed to describe the study sample of patients at entry to the study, especially emotional dimension (Hospital Anxiety and Depression scale), functional impact (abridged Migraine Specific Questionnaire), stress (Perceived Stress Scale) and coping behaviours (brief COPE inventory avoidance subscale, Coping Strategies Questionnaire catastrophizing subscale), as well as treatments used and their effectiveness and treatments prescribed at end of consultation. Results indicate that consulting migraine patients suffer frequent migraine attacks, exhibit substantial levels of anxiety, functional impact and stress, and often use maladaptive coping strategies. Abortive treatments appear ineffective in most patients (74%). Patients with more affected psychometric variables and treatment ineffectiveness are more likely to be deemed eligible for prophylactic treatment. These data highlight the seriousness of migraine and maladjustment of patients consulting in primary care.

Abstract: The objective of this analysis was to identify variables associated with treatment response in subjects with migraine. Data were collected from a sample of 10,000 subjects. A battery of questionnaires assessing clinical and psychological variables was completed. Migraine diagnosis was attributed using an algorithm based on the IHS criteria and treatment response using the ANAES criteria. We identified 1534 subjects, of whom 1443 were treated. For 54.2%, at least one ANAES criterion for treatment response was unfulfilled. Non-response was associated with female gender, high HIT-6 impact scores and high HAD psychological distress scores. The strongest associations with non-response were identified for four psychological variables: elevated scores on the CSQ catastrophization subscale and the 'Consequences' and 'Acceptance' dimensions of the Brief COPE, and low scores on the 'Positive Reinterpretation' Brief COPE dimension. In conclusion, many individuals with migraine respond inadequately to treatment. Behavioural interventions aimed at modifying coping strategies may improve outcome.

Abstract: The aim of this study was to evaluate determinants of consultation for migraine in a representative sample of the French general adult population. We interviewed 10,032 subjects, of whom 1534 fulfilled the International Headache Society diagnostic criteria for migraine. These were categorized into migraine, probable migraine and chronic migraine. Information was collected on consultation experience; 436 subjects (28.4%) had never consulted for headache, 473 (30.8%) were in active consultation and 625 (40.7%) had previously consulted but lapsed. Subjects with chronic migraine showed the highest active consultation rates (51.8%). All subjects completed rating instruments for headache [Headache Impact Test (HIT)-6], psychiatric (Hospital Anxiety and Depression Scale scale) and psychological [Brief Illness Perception Questionnaire (BIPQ), Brief COPE Inventory and Coping Strategy Questionnaire] variables. The strongest determinants of active consultation were BIPQ scores, HIT-6 scores and migraine type. Consultation was associated with maladaptive coping strategies (social support, emotional expression and acceptance). Determinants of remaining in consultation were catastrophizing coping scores and previous consultation experience.

Abstract: OBJECTIVE: To evaluate the proportion of migraineurs who are self-aware of their disease in France, to determine the factors (disability, quality of life, psychiatric comorbidities, and medical consultation) that may promote self-awareness of migraine, and to assess the influence of these factors on migraine attacks. BACKGROUND: New recommendations for migraine diagnosis and medical management were released in 2003 by the French medicoeconomic evaluation service (ANAES). In addition, the revised classification of headache disorders recently issued by the International Headache Society includes probable migraine as a form of migraine. However, strict and probable migraine now appear to be part of the same spectrum of disease. METHODS: Subjects with migraine (strict or probable) according to the revised classification were identified by a postal questionnaire from a large representative sample of the French adult population. Migraine-related disability was assessed using the MIDAS questionnaire, anxiety and depression by the Hospital Anxiety and Depression scale (HADS), and health-related quality of life (HRQoL) by the 8 concepts of the Short-Form 12 (SF-12) questionnaire. Migraine management was assessed according to the use of recommended or nonrecommended treatments, and treatment efficacy according to the set of 4 questions designed by the ANAES. RESULTS: Of the 10,532 subjects interviewed, 1,179 subjects (21.3%) were identified as migraineurs. Sixty percent of all migraine subjects were not self-aware that they had migraine. Medical consultation, duration of migraine history, severe intensity of attacks, impact on daily living, and female gender promoted self-awareness of migraine. On the other hand, HRQoL and anxiety and depression scores were not different between subjects self-aware or not self-aware of migraine. Only 20% of all migraine subjects were medically followed-up. Quality of the first medical consultation appears determinant for continued consulting. Subjects self-aware of migraine more frequently used recommended acute treatments of migraine, which proved more effective than nonrecommended treatments as assessed according to the ANAES set of questions. CONCLUSIONS: Migraine medical diagnosis and follow-up remain low in France. Careful medical consultation is a prime factor for migraine subject self-awareness of migraine, continued consultation, and use of recommended medications for the treatment of migraine attacks.

Abstract: Anxiety and depression are reported to be frequently associated with migraine but how they impact on migraine-related disability, migraine subjects' quality of life, and medical and therapeutic management of migraine attacks has not been investigated. FRAMIG 3 is a nation-wide population-based postal survey carried out in France according to the 2004 international classification of headache disorders. Subjects who had had migraine attacks during the last 3 months (subjects with 'active migraine', N = 1957) were analysed for migraine-related disability (MIDAS score), quality of life (SF-12 questionnaire), and anxiety and depression (Hospital Anxiety and Depression Scale [HADS]) in comparison with non-migraine subjects (N = 8287). Survey results indicate that 50.6% of subjects with active migraine were anxious and/or depressive (28.0% had anxiety alone, 3.5% depression alone, and 19.1% both anxiety and depression; P < or = 0.01 versus non-migraine subjects for anxiety alone and combined anxiety and depression, NS for depression alone). Although, migraine-associated anxiety and depression do not appear to influence the drugs taken by migraine subjects for the acute treatment of migraine attacks, perceived treatment efficacy and satisfaction with treatment are lower in subjects with anxiety alone or combined with depression than in subjects with neither anxiety nor depression. Anxiety and depression should be systemically looked for and cared for in subjects consulting for migraine.

Abstract: INTRODUCTION: A survey (NOEMIE, Nouvel Observatoire Epidemiologique de la Migraine en Entreprise) was carried out in France in 17 occupational healthcare units in order to identify subjects suffering from migraine headache with the aim of guiding them towards a healthcare program. The data collected in the participating units are presented. METHODS: and patients. NOEMIE was a national cross-sectional, observational, multicentric study with a 6-month follow-up. Two groups of migraine sufferers (according to IHS criteria) were included and divided into two groups: subjects already managed for their migraine (group A) and subjects who had not sought healthcare for migraine for more than 12 months (group B). The main objective was to evaluate changes in the quality-of-life score (QVM) 6 months later. RESULTS: At inclusion, the two groups were comparable for demographic features, history of migraine, and disease severity. A significant difference was observed between the two groups for frequency of attacks, disease management, and evaluation of treatment efficacy and of quality-of-life. At 6 months, patient satisfaction and quality-of-life were significantly improved (6 to 10 point improvement). For the 4753 reported attacks, 12.4 percent of the patients in group A required sick leave versus 10.9 percent in group B. Frequency of sick leave was considerably improved in both groups. CONCLUSION: By identifying subjects suffering from migraine headache who had not sought specific medical care and advising them to seek medical management, the employee healthcare units improved the subjects' quality-of-life, promoted adequate medical management and reduced occupational consequences of migraine headache.

Abstract: BACKGROUND: Migraine is a prevalent and incapacitating condition that affects individuals in the prime of their productive life, thus generating an economic burden for both society and healthcare systems. The direct annual healthcare costs of migraine in France were assessed over 10 years ago, and the current study updates these figures. OBJECTIVE: The objective of this study was to determine the economic cost (primarily direct costs) of migraine and other episodic headache in France based on a general population survey of headache, the GRIM2000 (Groupe de Researche Interdisciplinaire sur la Migraine). DESIGN: From a representative general population sample of 10,585 individuals aged > or = 15 years in France in 1999, 1486 individuals experiencing headaches were identified and interviewed regarding healthcare resource consumption in the previous 6 months. By applying unit costs to the resource data, costings (in 1999 values) were determined for physician consultations, hospitalisation, medication use and diagnostic/laboratory tests, and evaluated from a healthcare system perspective. Information on absenteeism and lost productivity was derived from the Migraine Disability Assessment Score (MIDAS) questionnaire. RESULTS: The prevalence of migraine (including migrainous disorder) was determined to be 17%. Total annual direct healthcare costs were estimated to be Euros 128 per individual with migraine in 1999, corresponding to Euros 1044 million when extrapolated to all individuals experiencing migraine and aged > or = 15 years. Around two-thirds of this cost accrued to the social security system (Euros 698 million; Euros 85 per individual). The total annual direct cost of other forms of episodic headache was much lower at Euros 28 per individual (social security cost Euros 18); with a prevalence of 9.2%, the annual national direct cost for other forms of episodic headache totalled Euros 124 million. The principal cost element was physician consultations. However, it was found that many individuals had never consulted a physician for their headaches, and self-medication contributed substantially to the medication costs (the second greatest cost factor for migraine). The cost per individual rose steeply with increasing severity of headache. CONCLUSIONS: The direct healthcare costs of migraine do not seem to have risen significantly over the past decade. A small minority of individuals with more severe headaches consume most of the healthcare resources devoted to migraine, while most individuals generate relatively low direct costs. The total annual direct costs in France for migraine are almost 10-fold higher than those of other episodic headache.

Abstract: OBJECTIVES: The objectives of this study were to determine the impact of headache on health-related quality of life in a nationwide sample of the French general population using a disease-specific measure, the Qualité de Vie et Migraine (QVM), to compare quality of life in subjects reporting different headache to types, and to evaluate the relationship between quality of life and severity, frequency, associated disability, and treatment responsiveness of headaches. METHODS: The QVM questionnaire was included within a large epidemiological survey of 1486 headache sufferers. Diagnosis was assigned retrospectively using an algorithm based on the International Headache Society classification. Headache severity was assessed with the MIGSEV scale and disability with the MIDAS scale. RESULTS: The mean global QVM score in the sample was 80.2. Quality of life was poorer in subjects with chronic daily headache (QVM score: 66.2) than in those with migraine (QVM score: 76.7), while those with other forms of episodic headache had the best quality of life (QVM score: 91.7). Quality-of-life scores were correlated with frequency, severity, disability, and treatment resistance of headaches (P <.001). CONCLUSION: The QVM scale is a sensitive tool to measure health-related quality of life in headache sufferers in the general population.

Abstract: Migraine remains an under-diagnosed disease. Many migraine sufferers are not currently treated within the healthcare system and most of them take self-medication. A prospective national study was conducted in France with 770 pharmacies. Data on symptoms, drug dispensing, patient management, and satisfaction of 7 264 subjects complaining of headache at the pharmacy were collected. Two-third of the subjects were migraine sufferers according to the IHS criteria. 32 p. cent of them came to the pharmacy during a pain attack. 63 p. cent had a medical prescription (46 p. cent in the non-migraine group) with triptans being most often prescribed drug (in almost half of the cases). Nearly one-third of the migraine sufferers without medical prescription were referred to a doctor by the pharmacist. This first study on migraine and headaches and pharmacies highlights the important role that pharmacists can play in improving the management of migraine and headache through advice and proper orientation towards medical practitioners.

Abstract: The extent and nature of triptan use for headache relief has been evaluated in a large epidemiological survey in the French general population. Over 25 000 individuals were screened for headache and for triptan use. Of this sample, 290 triptan users were identified from whom extensive data on headache characteristics and healthcare resource consumption were obtained. The use of triptans is relatively infrequent, 0.2% in the general population, with only 7.5% of migraine sufferers using these drugs. The majority of triptan users were female (80%) and presented headache characteristics typical of migraine (80%). The remaining 20% of subjects were thus using triptans for headache types in which the utility of these drugs has not been demonstrated. Among migraineurs, triptan consumers reported more frequent and severe headaches than non-consumers, and reported a higher incidence of nausea and vomiting. The principal determinant of triptan prescription was consultation with a general practitioner (GP), which may itself have been triggered by the severity of the headaches. GPs, rather than specialists, are the primary prescribers of triptans in France.

Abstract: The objective of this study was to describe the epidemiology, clinical presentation and consequences of chronic daily headache (CDH) in France. A representative nation-wide sample of the general population was identified using a stratified sampling method. Ten thousand five hundred and eight-five subjects were screened in face-to-face interviews, and data collected using a standard questionnaire. An overall point prevalence of CDH in the general population of 2.98% was observed. Two-thirds of these subjects presented migraine-like features. Severity, functional impact and healthcare consumption were higher than in subjects reporting episodic migraine in the same sample. Of the subjects, 28.2% reported the most severe migraine disability assessment scores (Grades 3 and 4), compared to 12% of episodic migraineurs. A qualité de vie et migraine score of 68.4 was observed, indicating severely attenuated quality of life. Only 6.6% of subjects were taking prophylactic treatment, whilst 88% were using non-specific acute headache treatments. The frequency of physician consultations and laboratory examinations was significantly higher than in individuals with episodic headache. CDH is thus a relatively prevalent condition in the general French population, associated with an important burden of suffering and with considerable expenditure in the health service. Management of this condition is generally inappropriate.

Abstract: OBJECTIVE: To determine the prevalence and clinical features of migraine and related headache types in France. METHODS: The authors recruited a population of subjects with headache representative of the national population using a stratified sampling method. They screened 10,585 subjects aged 15 and older who were representative of the general population. They identified 1,486 of these as having headaches, and these subjects were subsequently interviewed for information on clinical features, natural history, and functional impact of headache. The authors categorized subjects based on the International Headache Society (IHS) classification and assessed disability using the MIDAS questionnaire. RESULTS: The authors found a standardized prevalence for migraine (IHS categories 1.1 and 1.2) of 7.9% (11.2% for women and 4.0% for men) and 9.1% for migrainous disorder (IHS category 1.7). Migraine attacks were associated with a considerable degree of handicap in activities of daily living, with a MIDAS grade distribution of 74.7% (grade 1), 13.3% (grade 2), 7.7% (grade 3), and 4.3% (grade 4). The prevalence of migraine with MIDAS grade 3 or 4 was 1.6%. CONCLUSIONS: The prevalence of migraine (IHS categories 1.1 and 1.2) in France is 7.9%, and that of total migraine is 17.0%; this does not seem to have evolved over the past 10 years.

Abstract: A pharmacoepidemiological survey was conducted in order to understand the pattern of migraine prophylactic drug utilization by French physicians. Neurologists and primary care physicians completed a phone-mail-phone questionnaire which inquired about migraine prophylactic treatment. French neurologists and PCP made the same use of migraine prophylaxis in terms of indication, time interval between treatment onset and evaluation, and duration. The two most commonly chosen migraine prophylactic agents were dihydroergotamine and beta-blockers. This study also showed the importance of considering quality of life to evaluate efficacy of migraine prophylaxis.
