Changes in Use of Migraine Medications, Healthcare Resource Utilization, and Associated Direct Costs Over 12Months Following Initiation of Erenumab: A US Retrospective Real-World Analysis.

Erenumab-aooe is approved for the preventive treatment of migraine in adults. Recent publications have evaluated migraine medication use during the 6 months after starting erenumab, but longer-term follow-up data are limited. The objective of this study was to describe 12-month medication use and changes in healthcare resource utilization (HRU) and associated direct costs among patients initiating erenumab. We identified adult patients with an erenumab claim in the Merative MarketScan Commercial and Medicare Databases from May 2018 through September 2019. Eligible patients had ≥ 12months of continuous medical and pharmacy coverage before (pre-index period) and after (post-index period) the index date (first erenumab claim) in addition to pre-index evidence of migraine. Patients were stratified by post-index-period adherence to erenumab, defined as ≥ 80% of days covered (adherent) or < 80% of days covered (non-adherent). Outcomes were measured pre- and post-index, and differences between these periods were described. Among 7528 eligible patients, the mean (standard deviation) age was 45.1 (11.4) years and 85.4% were female; 38.5% of patients were adherent to erenumab. Most patients used acute or traditional migraine-preventive medications pre-index, with reductions in use observed post-index (acute medication was used by 95.6% of patients pre-index, compared to 92.3% post-index; traditional preventive medication was used by 89.6% of patients pre-index, compared to 81.9% post-index). Reductions were observed for HRU of emergency room visits (-3.8%) and brain- and other head-imaging studies (-7.5%). Overall costs associated with acute and traditional preventive medications were reduced (-$764), but costs for HRU increased slightly ($76). When stratifying by adherence and combining costs for acute and traditional preventive medications and HRU, adherent patients had cost decreases (-$1947), while non-adherent patients had cost increases ($101). Most patients initiating erenumab had prior use of acute and traditional migraine-preventive therapies. The reduction in acute and traditional migraine-preventive medication use and HRU over the 12-month follow-up supports the long-term clinical benefits of erenumab in the real-world setting.

Treatment patterns of patients with migraine eligible for anti-CGRP pathway monoclonal antibodies.

Migraine is a debilitating neurological disorder, with a wide range of symptoms and disease burden, underscoring the heterogeneity of patients' disease characteristics and treatment needs. To characterize the profile of migraine patients in the US who may be eligible for preventive treatment with an anti-CGRP pathway mAb and to better understand treatment patterns and real-world use of acute and preventive medications for migraine, we conducted a retrospective cohort study of adult patients. These patients were identified as having migraine using diagnosis codes or migraine-specific medication use (first = index) in the IQVIA PharMetrics® Plus database. Patients were required to have ≥ 12 months of continuous enrollment in medical and pharmacy benefits prior to index (baseline) and after index (follow-up). Patients were stratified into chronic migraine (CM) and non-chronic migraine (non-CM) by diagnosis codes. Based on acute migraine-specific medication dispensing data in the follow-up period, non-CM patients were divided into 3 cohorts: highest, middle, and lowest tertile of total units of dispensed acute migraine-specific medication (gepants, ditans, ergot derivatives, and triptans). Migraine medication use was captured in the baseline and follow-up periods. A total of 22,584 CM and 216,807 non-CM patients (72,269 patients in each tertile) were identified and included in the study. Over the follow-up, CM patients had a mean of 70 units of acute migraine-specific medications dispensed, while the highest, middle, and lowest tertile of non-CM patients had a mean of 92, 29, and 10 units, respectively. Anti-calcitonin gene-related peptide pathway mAbs were dispensed for 28.9% of CM patients, and for 6.9%, 4.1%, and 2.9% of non-CM patients in the highest, middle, and lowest tertiles, respectively. A lower proportion of non-CM patients had use of anti-calcitonin gene-related peptide pathway mAbs compared to CM patients, confirming the unmet need with appropriate preventive medication. There appears to be a persistent gap in management of patients without a diagnosis of CM who are dispensed high quantities of acute migraine-specific medications.

Patterns of migraine medication use in Norway: A nationwide registry-based observational study.

The objective of this study was to describe and discuss patterns of migraine medication use in the entire Norwegian population. In this nationwide, observational study, all individuals with a migraine-related prescription between 2010 and 2020 were identified using the Norwegian Prescription Database. The outcomes of interest were the incidence and 1-year prevalence of migraine medication users, as well as individuals with triptan overuse. Patterns of medication use were statistically compared between women and men adjusted for age, year of treatment start, comorbidities and county of residence calculating adjusted odds ratios (aOR) with 95% confidence intervals (CI). We identified 327,904 migraine medication users. The incidence ranged from 0.39% to 0.46%, and the 1-year prevalence increased from 1.99% to 2.99%. Preventive use increased >50% during the study period. Preventives were significantly more often prescribed to women than to men (39.72% vs. 33.75%; aOR 1.41, 95% CI 1.38 to 1.44). Triptan overuse was significantly more common among women, but women with overuse were more often using preventives, as compared to men (56.64% vs 52.69%; aOR = 1.43, 95% CI 1.37 to 1.49). The prevalence of medically treated migraine is low. Overuse of triptans is frequent, especially among women. Clinicians should be encouraged to try out different triptans, recognize triptan overuse, and prescribe preventives when indicated.

Use of medications for migraine in Aotearoa New Zealand.

To document and assess acute and preventive medication use in people with migraine disease in Aotearoa New Zealand. Online survey of people with migraine in Aotearoa New Zealand (n=530), run from 22 August to 7 October 2022, including questions on current and previous acute and preventive medication use, reasons for medication discontinuation and use of new migraine medications. Most respondents had used simple analgesics for acute treatment; 55% were currently using a triptan; 27% were currently using an opioid. Overall, 27% of survey respondents had over-used at least one acute medication in the last month. Half of respondents were taking at least one preventive medication but only 57% of those eligible for preventive treatment were currently taking it. In those who had previously tried preventives, side effects and lack of efficacy were common reasons for stopping. Cost, lack of knowledge and awareness were the main barriers to use of new migraine medications. Many people with migraine in Aotearoa New Zealand are not receiving optimal treatment, which increases the burden and cost of migraine disease. More effective and tolerable acute and preventive medications are needed that are affordable and available in Aotearoa New Zealand. Greater awareness of best practice prescribing is also needed.

The impact of updates in headache quality measures on adherence to best practices in a neurology resident clinic: Aquality improvement study.

To apply the 2019 joint American Academy of Neurology (AAN) and American Headache Society (AHS) quality measures for headache management to a cohort of neurology resident physicians and then assess outcomes related to guideline adherence. The optimization of headache management is essential to reduce both the individual and systemic impact of these disorders. In 2014, the AAN developed 10 quality measures for evidence-based management of patients with headache. A workgroup updated and condensed its headache quality measures in 2019, narrowing the set to six measurements, four of which would primarily focus on the management of migraine and two of which would address the management of cluster headache. This quality improvement study was conducted using a pretest-posttest study design. A pre-intervention survey based on retrospective analysis of five clinic notes for adherence to the measures was designed and distributed to all neurology residents (n = 32) at a large, academic tertiary referral center. The intervention included the creation of an electronic medical record template to aid residents in following the measures during clinical encounters, as well as the provision of direct feedback based on pre-intervention results. Finally, a post-intervention survey was distributed for completion based on notes written during the intervention period. Analysis was limited to migraine, given the low percentage of cluster headache seen in clinic. An increase in adherence was seen in three of the four migraine-related quality measures, with the Use of Abortive Medications for Migraine and Documentation of Counseling on Modifiable Lifestyle and Chronification Factors demonstrating statistically significant improvements (75.8% to 88.0% [p = 0.013] and 83.9% to 94.0% [p = 0.029] adherence, respectively). For secondary outcomes, the increase in the utilization of appropriate diagnostic criteria (82.6% to 93.2%, p = 0.018) was significant, and the self-assessed confidence rating for adherence to guidelines was significant (p < 0.001). This study provides evidence that the quality improvement intervention led to increased adherence to the AAN and AHS migraine-related measures. It is anticipated that increased adherence may lead to improved patient outcomes.

A Narrative Review of Intestinal Microbiota's Impact on Migraine with Psychopathologies.

Migraine is a common and debilitating neurological disorder characterized by the recurrent attack of pulsating headaches typically localized on one side of the head associated with other disabling symptoms, such as nausea, increased sensitivity to light, sound and smell and mood changes. Various clinical factors, including the excessive use of migraine medication, inadequate acute treatment and stressful events, can contribute to the worsening of the condition, which may evolve to chronic migraine, that is, a headache present on >15 days/month for at least 3 months. Chronic migraine is frequently associated with various comorbidities, including anxiety and mood disorders, particularly depression, which complicate the prognosis, response to treatment and overall clinical outcomes. Emerging research indicates a connection between alterations in the composition of the gut microbiota and mental health conditions, particularly anxiety and depression, which are considered disorders of the gut-brain axis. This underscores the potential of modulating the gut microbiota as a new avenue for managing these conditions. In this context, it is interesting to investigate whether migraine, particularly in its chronic form, exhibits a dysbiosis profile similar to that observed in individuals with anxiety and depression. This could pave the way for interventions aimed at modulating the gut microbiota for treating difficult-to-manage migraines.

Burden of Medication Overuse in Migraine: A Cross-sectional, Population-Based Study in Five European Countries Using the 2020 National Health and Wellness Survey (NHWS).

Overuse of medication to treat migraine attacks can lead to development of a new type of headache or significant worsening of pre-existing headache, known as medication overuse headache. However, data concerning the burden of medication overuse (MO) in migraine are limited. This study aimed to assess the humanistic burden of MO in individuals with migraine from five European countries. Data are from the 2020 National Health and Wellness Survey-a cross-sectional, population-based survey conducted in France, Germany, Italy, Spain, and the UK. Data were included from adults (≥ 18years) with a self-reported diagnosis of migraine and at least one migraine attack and one headache in the past 30days. MO was defined as (i) use of simple analgesics/over-the-counter medications on ≥ 15days/month; or (ii) use of migraine medication, including combination analgesics, on ≥ 10days/month. Humanistic burden of MO was assessed using the 12-Item Short-Form Health Survey (SF-12v2), EuroQol 5-Dimensions 5-Levels (EQ-5D), Short-Form 6-Dimensions (SF-6D), and Migraine Disability Assessment (MIDAS). The association of MO with humanistic burden was evaluated using generalized linear models adjusted for potential confounders in the full migraine population and in subgroups defined by headache frequency (monthly headache days [MHDs] 1-3, 4-7, 8-14, or ≥ 15). Among individuals with migraine, humanistic burden (SF-12v2, SF-6D, EQ-5D, and MIDAS) was higher in individuals who reported MO (n = 431) versus no MO (n = 3554), even after adjustment for confounding variables (p < 0.001 for all measures). MIDAS and EQ-5D scores were higher in individuals with MO than without, at all levels of headache frequency. For SF-12v2 and SF-6D, differences between groups with/without MO were seen only at lower levels of headache frequency (MHD 1-3 and 4-7). Among people with migraine, those who report MO face a greater humanistic burden than those without MO, irrespective of headache frequency.

Trajectory of health care resources among adults stopping or reducing treatment frequency of botulinum toxin for chronic migraine treatment in Alberta, Canada.

Understand health resource, medication use, and cost of adults with chronic migraine who received guideline-recommended onabotulinumtoxinA (botulinum toxin) treatment frequency and then continued or reduced/stopped. Botulinum toxin may be a beneficial treatment for chronic migraine; the trajectory of health resources utilization among those with continued or reduced/stopped use is unclear. A retrospective population-based cohort study utilizing administrative data from Alberta, Canada (2012-2020), was performed. A cohort of adults who received ≥5 botulinum toxin treatment cycles for chronic migraine over 18 months (6-month run-in; 1-year pre-index period) were grouped into those who (1) continued use (≥3 treatments/year), or (2) stopped or reduced use (stopped for 6 months then received 0 or 1-2 treatments/year, respectively) over a 1-year post-index period. Health resources and medication use were described, and pre-post costs were assessed. A second cohort that received ≥3 treatments/year immediately followed by 1 year of stopped or reduced use was considered in sensitivity analysis. Pre-post health resource, medication use, and costs were similar among those with continued use (n = 3336). Among those who stopped or reduced use (n = 1099; 756 stopped, 343 reduced), health resource, medication use, and costs were lower in the post- (total median per-person cost [IQR]: all-cause $4851 [$8090]; migraine-related $835 [$1915]) versus pre- (all-cause $6096 [$7207]; migraine-related $2995 [$1950]) index period (estimated cost ratios [95% CI]: total all-cause 0.86 [0.79, 0.95]; total migraine-related 0.44 [0.40, 0.48]). In the second cohort (n = 3763), return to continued use (≥3 treatments/year) occurred in up to 70.4% in those with reduced use. Of adults treated with botulinum toxin for chronic migraine, 75.2% had continued use, stable health resource and medication use, and costs over a 2 year period. In those that stopped/reduced use, the observed lower health resource and migraine medication use may indicate improved symptom control, but the resumption of guideline-recommended treatment intervals after reduced use was common.

Migraine and risk of hypertensive disorders of pregnancy: A population-based cohort study.

Migraine is associated with hypertensive disorders of pregnancy through common pathophysiological features. This study evaluates the association between migraine diagnosis and treatment, and risk of hypertensive disorders of pregnancy. We conducted a prospective cohort study in the Clinical Practice Research Datalink GOLD, a large longitudinal database of patient records in the UK. We analyzed data from liveborn or stillborn singleton deliveries from 1993-2020 with at least 24 months of medical history and no history of cardiovascular disease (n = 1,049,839). We ascertained migraine through diagnosis or prescription codes before 20 weeks of gestation and hypertensive disorders of pregnancy through diagnosis codes between 20 weeks of pregnancy and delivery. We used log-binomial regression models to estimate the risk ratio and 95% confidence intervals, comparing risk of hypertensive disorders of pregnancy among individuals with migraine to those without migraine, adjusting for confounders. A history of migraine prior to pregnancy was associated with an increased risk of hypertensive disorders of pregnancy (RR = 1.17, 95% CI: 1.09-1.26). The greatest risk was among those with pre-pregnancy migraine that persisted into the first trimester (RR = 1.84, 95% CI: 1.35-2.50). Use of migraine medication was associated with a higher risk of hypertensive disorders of pregnancy compared to non-migraineurs (RR = 1.50, 95% CI: 1.15-1.97). Results from this study indicate that migraine is a potential risk factor for hypertensive disorders of pregnancy.

Impact of COVID-19 Pandemic Lockdown on Migraine Patients in Latin America.

The coronavirus (COVID-19) pandemic, confinement, fear, lifestyle changes, and worldwide health care impacted almost all diseases. Reports from countries outside Latin America revealed differences in migraine patients. In this study, we describe and compare the immediate changes in migraine symptoms associated with COVID-19 quarantine in patients from Argentina, Mexico, and Peru. An online survey was conducted from May to July 2020. The survey was answered by 243 migraine patients, with questions related to sociodemographic data, quarantine conditions, changes in working conditions, physical activity, coffee intake, healthcare access, acute migraine medication use, symptoms of anxiety, depression, and fear of COVID-19. The results show that 48.6% of migraine patients experienced worsened symptoms, 15.6% improved, and 35.8% remained unchanged. Worsening migraine symptoms were associated with staying at home during the lockdown. Intake of analgesics was associated with an increase in migraine symptoms of 18 times relative to those who did not increase their intake. Migraine symptoms improved when the number of sleep hours was increased, and we observed an improvement when patients decreased analgesic intake. The uncertainty about the end of the pandemic, the news, and social media are three items that contributed to the worsening of migraine symptoms in patients in the three investigated countries. Confinement during the first pandemic wave in Latin America harmed migraine patients who stayed home during the lockdown.

Pre-pregnancy migraine diagnosis, medication use, and spontaneous abortion: a prospective cohort study

BackgroundMigraine is common among females of reproductive age (estimated prevalence:17–24%) and may be associated with reproductive health through underlying central nervous system excitability, autoimmune conditions, and autonomic dysfunction. We evaluated the extent to which pre-pregnancy migraine diagnosis and medication use are associated with risk of spontaneous abortion (SAB).MethodsWe analyzed data from a preconception study of pregnancy planners (2013–2021). Eligible participants self-identified as female, were aged 21–45 years, resided in the USA or Canada, and conceived during follow-up (n = 7890). Participants completed baseline and bimonthly follow-up questionnaires for up to 12 months or until a reported pregnancy, whichever occurred first. Pregnant participants then completed questionnaires during early (~ 8–9 weeks) and late (~ 32 weeks) gestation. We defined migraineurs as participants who reported a migraine diagnosis or use of a medication to treat migraine. Preconception questionnaires elicited migraine medication use during the past 4 weeks, and SAB on follow-up and pregnancy questionnaires. We used Cox regression models with gestational weeks as the time scale to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for associations among preconception migraine, migraine medication use, and SAB, controlling for potential demographic, medical, and lifestyle confounders.ResultsNineteen percent of study pregnancies ended in SAB. History of migraine before conception was not appreciably associated with SAB risk (HR = 1.03, 95% CI: 0.91–1.06). Use of any migraine medication was associated with a modest increase in SAB risk overall (HR = 1.14, 95% CI: 0.96–1.36). We observed the greatest increase in risk among those taking migraine medications daily (HR = 1.38, 95% CI: 0.81–2.35) and those taking prescription migraine prophylaxis (HR = 1.43, 95% CI: 0.72–2.84) or combination analgesic and caffeine medications (HR = 1.42, 95% CI: 0.99–2.04).ConclusionsMigraine medication use patterns suggesting greater underlying migraine severity were associated with increased risk of SAB. This research adds to the limited information available on the reproductive effects of migraine.

The association between migraine and dementia – a national register-based matched cohort study

ObjectivesMigraine and dementia, two major public health challenges, are associated, but more knowledge is needed to understand their relationship. Objectives of this study were to investigate 1) the association between non–self-reported measures of migraine and dementia, and whether dementia was associated with 2) migraine without aura (MO) and with aura (MA) in combination with migraine medication use, and 3) migraine severity operationalized as the number of migraine prescriptions. Study designMatched cohort study. MethodsNational register data were obtained from individuals born between 1934 and 1958. Migraine cases (aged 25–58 years) were identified by migraine diagnoses and redeemed migraine medication. Migraine cases were matched with non-cases (N = 340,850) and date of diagnosis or medication redemption was defined as index year. Dementia was identified by dementia diagnoses and redeemed dementia medication. ResultsWe observed a 1.46 (95% CI: 1.26–1.69) times higher dementia rate in individuals with a migraine diagnosis and a 0.86 (95% CI: 0.76–0.97) times lower rate when using migraine medication. We found the highest dementia rate among individuals with MA, who also used migraine medication (HR = 2.23; 95% CI: 1.19–4.17), and the lowest rate among individuals with MO, who also used medication (HR = 1.25; 95% CI: 0.75–2.10). The number of migraine medication prescriptions was not associated with dementia. ConclusionsBeing registered with a migraine diagnosis was associated with a higher dementia rate, while use of prescribed migraine medication was not. The differences in the dementia rate among migraine cases identified via diagnoses versus medications warrants further investigation.

Use of Non-pharmacological Therapies in Individuals With Migraine Eligible for Treatment With Monoclonal Antibodies Targeting Calcitonin Gene-Related Peptide (CGRP)-Signaling: A Single-Center Cross-Sectional Observational Study.

IntroductionAccessibility of treatment with monoclonal antibodies targeting the calcitonin gene-related peptide (CGRP) signaling pathway is impeded by regulatory restrictions. Affected individuals may seek out other services including non-pharmacological therapies. Thus, we found it timely to ascertain the use of non-pharmacological therapies in individuals with treatment-resistant migraine eligible for and naïve to treatment with CGRP-signaling targeting monoclonal antibodies.MethodsWe conducted a single-center cross-sectional observational study of patients eligible for and naïve to treatment with monoclonal antibodies targeting CGRP or its receptor. We recorded demographical information (gender, age, educational level, employment status, and income), disease burden (frequency of headache days and migraine days), previous use of preventive pharmacological medications for migraine, and use of non-pharmacological therapies over the past 3 months including frequency of interventions, costs, and patient-reported assessment of efficacy on a 6-point scale (0: no efficacy, 5: best possible efficacy).ResultsWe included 122 patients between 17 June 2019 and 6 January 2020; 101 (83%) were women and the mean age was 45.2 ± 13.3 years. One-third (n = 41 [34%]) had used non-pharmacological therapy within the past 3 months. Among these participants, the median frequency of different interventions was 1 (IQR: 1–2), the median number of monthly visits was 2.3 (IQR: 1.3–4), mean and median monthly costs were 1,086 ± 1471, and 600 (IQR: 0–1200) DKK (1 EUR = ~7.5 DKK), respectively, and median patient-reported assessment of the efficacy of interventions was 2 (IQR: 0–3).ConclusionEven in a high-income country with freely accessible headache services and universal healthcare coverage, there was a non-negligible direct cost in parallel with low satisfaction for non-pharmacological therapies among patients at a tertiary headache center.

Prevention of medication overuse and medication overuse headache in patients with migraine: a randomized, controlled, parallel, allocation-blinded, multicenter, prospective trial using a mobile software application

BackgroundOverall, 55% of the German population suffers from primary episodic headaches according to recent studies. Inadequate management of headache disorders is a significant medical problem. The prevalence of medication overuse headache (MOH) is about 1% with an estimated number of 800,000 people in Germany. Medication overuse (MO) and MOH are usually managed through a complex process of medication withdrawal and initiating of prophylaxis. However, patients who were successfully treated for MO or MOH have a high relapse rate in the following 2 years. Previously, continued monitoring of self-reported medication intake demonstrated lower relapse rates. The prevalence and burden of MO and MOH are high, and effective strategies to prevent the development of a relapse into MOH or de novo MOH are still missing. Therefore, the MOH trial was designed to assess the effects of combining self-reported medication intake with daily monitoring of the entered data and a personalized patient-specific medication intake feedback system in an easy-accessible app-based platform in order to prevent the development and relapse of MO(H).MethodsThe MOH trial is a randomized, controlled, parallel, multicenter, prospective trial. A total of 624 migraine patients with frequent migraine attacks and 336 patients who underwent treatment for MO(H) will be randomly allocated to use either a customized app with or without individual feedback regarding their self-reported medication intake for 12 months. The primary outcome will be the proportion of patients developing MO or MOH for at least 3 consecutive months between baseline and end of study visits.DiscussionThis trial will assess the effects of providing patients with feedback regarding their self-reported use of migraine medications and migraine days using a mobile software on the development or prevention of MO(H). We hypothesize that the development of MO(H) in patients with frequent episodic migraine (EM) or chronic migraine (CM) and relapse after treatment of MO(H) can be reduced by a feedback system. If this trial proves that using an app with specific and unspecific messaging to the patient is successful, this method, which is now investigated mainly in specialized headache centers, could later be extended to primary care, thus providing benefits for a broader patient group.Trial registrationGerman Clinical Trials Register DRKS00025961.

A real-world study of acute and preventive medication use, adherence, and persistence in patients prescribed fremanezumab in the United States

BackgroundFollowing approval of fremanezumab for the prevention of migraine in adults, health care decision makers are interested in understanding real-world clinical characteristics and treatment patterns among patients initiating fremanezumab therapy.MethodsData were obtained for this retrospective (pre-post) study from the Veradigm Health Insights database. The study period was January 1, 2014, to June 30, 2019. Patients were included if they were aged ≥ 18 years; had ≥ 1 migraine diagnosis during the study period; and had a medication record for fremanezumab on or after diagnosis during the identification period (September 1, 2018–December 31, 2018). Treatment patterns, including adherence, persistence, and utilization of acute and preventive migraine medication prescriptions, were evaluated.ResultsOf 987 patients initiating fremanezumab during the study period, 738 (74.8%) were adherent to fremanezumab by proportion of days covered (PDC; ≥ 80%) and 780 (79.0%) were adherent by medication possession ratio (MPR; ≥ 80%). A total of 746 (75.6%) patients were persistent for ≥ 6 months. Quarterly fremanezumab (n = 186) was associated with higher rates of adherence versus monthly fremanezumab (n = 801) by PDC (quarterly, 91.3%; monthly, 84.9%; P < 0.001) and MPR (quarterly, 92.2%; monthly, 87.9%; P = 0.006) and higher persistence at ≥ 6 months (quarterly, 82.8%; monthly, 73.9%; P = 0.011). After fremanezumab initiation, patients who were persistent for ≥ 6 months experienced significant reductions from baseline in the mean monthly number of acute and preventive migraine medication prescriptions (P < 0.001). Subgroup analyses in patients with comorbid depression and anxiety showed meaningful real-world benefits based on significant reductions in the number of patients who were prescribed antidepressants (baseline, 68.6%; follow-up, 56.4%; P = 0.0025) and anxiolytic medications (baseline, 55.0%; follow-up, 47.2%; P = 0.037), respectively. In a subgroup of patients with comorbid hypertension at baseline, fremanezumab treatment resulted in nonsignificant reductions in blood pressure.ConclusionsOverall, adherence and persistence to fremanezumab in this real-world study was high in patients with migraine, with higher rates observed for quarterly fremanezumab. Patients who were persistent for ≥ 6 months experienced significant reductions in acute and preventive migraine medication use, while a subgroup of migraine patients with comorbid depression and anxiety at baseline showed significant reductions in antidepressant and anxiolytic medication use.

Migraine without Aura Correlation with Anxiety Level and Socio- Demographic Characteristics

Purpose: Different types of migraine may be studied separately to understand their epidemiology and pathophysiology better. No studies have investigated patients with associated factors of anxiety severity in migraine without auras. Therefore, in this study, anxiety and its associated factors were investigated in a sample of Saudi Arabian patients with migraine without aura. Methods: A cross-sectional study of 122 conveniently sampled migraine patients at Madinah hospitals, Saudi Arabia, completed the Generalized anxiety disorder-7 scale (GAD-7), and a tool for social, demographics, and clinical information. Results: The majority of patients who did not have an aura with their migraine were female (67.2%); many did not report participating in sports activities (58.2%), or have a family history of migraine-headaches (74.6%). Anxiety severity was higher in migraine-without-aura patients, and those undergoing treatment for co-morbid conditions (β = .547, p = .042), those without family history of migraine/chronic headache (β = .016, p = .016), and patients with high frequency of migraine medication use (β = .009, p = .009). Discussion: The correlation of the anxiety severity level in patients who have migraines without aura may have important clinical, and epidemiological implications. females with their change in hormonal stat have a higher prevalence of migraine without aura, those with no habitual sport activity, and family history of migraine may indicate the need for targeted screening for migraine in these groups.

Comprehensive population-based survey of migraine in Japan: results of the ObserVational Survey of the Epidemiology, tReatment, and Care Of MigrainE (OVERCOME [Japan]) study

Objective The ObserVational survey of the Epidemiology, tReatment, and Care Of MigrainE study in Japan (OVERCOME [Japan]) aimed to provide an up-to-date assessment of migraine epidemiology in Japan. Methods OVERCOME (Japan) was a cross-sectional, population-based web survey of Japanese adults recruited from consumer panels. People with active migraine (met modified International Classification of Headache Disorders, 3rd edition [ICHD-3] criteria or had a self-reported physician diagnosis of migraine) answered questions about headache features, physician consultation patterns, and migraine medication use. The burden and impact of migraine were assessed using Migraine Disability Assessment (MIDAS) and Work Productivity and Activity Impairment scales. Results In total, 231,747 respondents accessed the screener, provided consent, and were eligible for the survey. The migraine group included 17,071 respondents (mean ± SD age 40.7 ± 13.0 years; 66.5% female). ICHD-3 migraine criteria were met by 14,033 (82.2%) respondents; 9667 (56.6%) self-reported a physician diagnosis of migraine. The mean number of monthly headache days was 4.5 ± 5.7 and pain severity (0–10 scale) was 5.1 ± 2.2. In the migraine group, 20.7% experienced moderate to severe migraine-related disability (MIDAS score ≥ 11). Work productivity loss was 36.2% of work time missed, including 34.3% presenteeism. Only 57.4% of respondents had ever sought medical care for migraine/severe headache. Most respondents (75.2%) were currently using over-the-counter medications for migraine; 36.7% were using prescription nonsteroidal anti-inflammatory drugs, and only 14.8% were using triptans. Very few (9.2%) used preventive medications. Conclusions Unmet needs for migraine health care among people with migraine in Japan include low rates of seeking care and suboptimal treatment.
