Average steps per day as marker of treatment response with anti-CGRP mAbs in adults with chronic migraine: a pilot study.

Physical activity can worsen migraine, leading to reduced activity levels in adults with chronic migraine. This study investigated the change in average steps per day, as a surrogate marker of physical activity, in adults with chronic migraine successfully treated with monoclonal antibodies against calcitonin gene-related peptide or its receptor. Data were obtained from adults with chronic migraine, who were classified as responders to preventive treatment with monoclonal antibodies. The primary endpoint was the difference in a mean number of steps per day between the 3 months prior to treatment initiation and the first 3 months after treatment initiation. The secondary endpoint was the correlation between the change in steps per day and the change in monthly migraine days. Twenty-two (20 females) participants with a median age of 48.5 years were enrolled. The median number of steps per day increased from 4421 at baseline to 5241 after treatment (P = 0.039). We found a positive correlation between the increase in steps per day and the treatment response (P = 0.013). In conclusion, an increase in physical activity, based on steps per day, positively correlated with treatment response to monoclonal antibodies. Automatically registered daily step count data might be used to monitor physical activity as a response to preventive treatment in adults with chronic migraine.

Induction of cGMP-mediated migraine attacks is independent of CGRP receptor activation.

BACKGROUND: The cAMP and cGMP pathways are implicated in the initiation of migraine attacks, but their interactions remain unclear. Calcitonin gene-related peptide (CGRP) triggers migraine attacks via cAMP, whereas the phosphodiesterase-5 inhibitor sildenafil induces migraine attacks via cGMP. Our objective was to investigate whether sildenafil could induce migraine attacks in individuals with migraine pre-treated with the CGRP-receptor antibody erenumab. METHODS: In this randomized, double-blind, placebo-controlled, cross-over study, adults with migraine without aura received a single subcutaneous injection of 140 mg erenumab on day 1. They were then randomized to receive sildenafil 100 mg or placebo on two experimental days, each separated by at least one week, between days 8 and 21. The primary endpoint was the difference in the incidence of migraine attacks between sildenafil and placebo during the 12-h observation period after administration. RESULTS: In total, 16 participants completed the study. Ten participants (63%) experienced a migraine attack within 12 h after sildenafil administration compared to three (19%) after placebo (p = 0.016). The median headache intensity was higher after sildenafil than after placebo (area under the curve (AUC) for the 12-h observation period, p = 0.026). Furthermore, sildenafil induced a significant decrease in mean arterial blood pressure (AUC, p = 0.026) and a simultaneous increase in heart rate (AUC, p < 0.001) during the first hour after administration compared to placebo. CONCLUSION: These findings provide evidence that migraine induction via the cGMP pathway can occur even under CGRP receptor blockade. TRIAL REGISTRATION: ClinicalTrials.gov: Identifier NCT05889455.

Pharmacological management of migraine: current strategies and future directions.

INTRODUCTION: Migraine is a complex neurological disorder that affects a significant portion of the global population. As traditional pharmacological approaches often fall short in alleviating symptoms, the development of innovative therapies has garnered significant interest. This text aims to summarize the current pharmacological options for managing migraine and to explore the potential impact of novel therapies. AREAS COVERED: We focused on conventional treatments, emerging therapies, and novel compounds in clinical development, including therapies targeting the trigeminovascular system, cannabis-based therapies, hormonal and metabolic therapies, and other options. English peer-reviewed articles were searched in PubMed, Scopus, and ClinicalTrials.gov electronic databases. EXPERT OPINION: Several novel treatment options for migraine have become available in recent years. Emerging pharmacological therapies targeting the trigeminovascular system, cannabis-based therapies, hormonal and metabolic interventions, and other emerging treatment modalities, may prove to be valuable for the treatment of migraine. Further research, clinical trials, and substantiated evidence are necessary to validate the efficacy, safety, and long-term outcomes of these therapeutic options.

Visual migraine aura iconography: A multicentre, cross-sectional study of individuals with migraine with aura.

INTRODUCTION: Visual disturbances are the most common symptoms of migraine aura. These symptoms can be described systematically by subdividing them into elementary visual symptoms. Since visual symptoms of migraine aura are not easy to describe verbally, we developed a collection of images illustrating previously reported elementary visual symptoms. OBJECTIVES: To test a standardised visual migraine aura iconography in a large population of migraine with aura patients and to improve it based on the participants' feedback. METHODS: We created a set of images representing 25 elementary visual symptoms and a web-based survey where participants could report whether they recognised these images as part of their visual aura. Elementary visual symptoms could also be recognised via a corresponding text description or described in a free text by participants. Individuals with migraine aura recruited from four tertiary headache centres (in Switzerland, Denmark, Norway and Italy) were invited to complete the survey. RESULTS: Two hundred and fifteen participants completed the study (78.9% women, median age 36). They recognised a total of 1645 elementary visual symptoms from our predefined list. Of those, 1291 (78.4%) where recognised via standardised iconography images. A new type of elementary visual symptom was reported by one participant. CONCLUSION: Most elementary visual symptoms experienced by participants were recognised via the standardised iconography. This tool can be useful for clinical as well as research purposes.

No wearing-off effect of erenumab or fremanezumab for chronic migraine prevention: a single-center, real-world, observational study.

BACKGROUND: The present study investigates the wearing-off effect in adults with chronic migraine treated with erenumab or fremanezumab. METHODS: This real-world observational study was based on pre-collected headache diaries from chronic migraine patients in treatment with either monthly injections of 140 mg of erenumab or 225 mg of fremanezumab. Consistent wearing-off was defined as an increase of ≥2 weekly migraine days in the last week compared to the second week over two consecutive 4-week treatment periods. The primary endpoint was wearing-off in the total population. The secondary endpoints were difference in wearing-off in (i) a subgroup of patients treated with erenumab and fremanezumab and (ii) consistent wearing-off in patients with a ≥30% reduction in monthly migraine days, compared to baseline, in the two consecutive treatment months. RESULTS: In total, 100 patients (erenumab: n = 60, fremanezumab: n = 40) were included. Sixty-two out of 100 (62%) patients had consistent ≥30% treatment response on antibody therapy in both months (erenumab: n = 36, fremanezumab: n = 26). There was no consistent wearing-off over the two consecutive months from week 2 to week 4 (3.04%, p = 0.558). There was no wearing-off within the erenumab (p = 0.194) or the fremanezumab (p = 0.581) groups. Among the ≥30% treatment responders, there was no consistent wearing-off over the two consecutive months (2.6%, p = 0.573). CONCLUSIONS: There was no wearing-off in treatment responders, which is in alignment with premarketing data from placebo-controlled phase III studies. These data suggest that patients should be informed upfront that no wearing-off effect is expected because anxiety for attacks at the end of the month per se may generate migraine attacks.

Pharmacotherapies for Migraine and Translating Evidence From Bench to Bedside.

Migraine is a ubiquitous neurologic disorder that afflicts more than 1 billion people worldwide. Recommended therapeutic strategies include the use of acute and, if needed, preventive medications. During the past 2 decades, tremendous progress has been made in better understanding the molecular mechanisms underlying migraine pathogenesis, which in turn has resulted in the advent of novel medications targeting signaling molecule calcitonin gene-related peptide or its receptor. Here, we provide an update on the rational use of pharmacotherapies for migraine to facilitate more informed clinical decision-making. We then discuss the scientific discoveries that led to the advent of new medications targeting calcitonin gene-related peptide signaling. Last, we conclude with recent advances that are being made to identify novel drug targets for migraine.

Metaphorical use of "headache" and "migraine" in media: A longitudinal study of 1.3 million articles in major publications.

BACKGROUND: Stigmatization and trivialization of headache confront individuals with headache disorders, but the degree to which media may contribute is incompletely understood. OBJECTIVE: The objective of this study was to quantify the frequency of disparaging metaphorical use of the words "headache" and "migraine" in articles and summaries of major publications. METHODS: This longitudinal study analyzed a dataset of 1.3 million articles and summaries written by authors and editors of 38 major publications. Data cover written publications from 1998 up to 2017. The use of the words "headache" or "migraine" in articles and summaries by major publications was rated by two authors (P.Z. and A.V.) as either "metaphorical" or "medical" based on their contextual application. Pearson's chi-squared test was applied to assess differences in the frequency of metaphorical use of "headache" in comparison to "migraine." Secondary outcomes were the source of publication and time of publication. RESULTS: A total of 6195 and 740 articles included the words "headache" or "migraine," respectively; 7100 sentences contained the word "headache" and 1652 sentences contained the word "migraine." Among a random sample of 1000 sentences with the word "headache," there was a metaphorical use in 492 (49.2% [95% CI, 46.1-52.3]) sentences. Among a random sample of 1000 sentences with the word "migraine," there was a metaphorical use in 45 (4.5% [95% CI, 3.2-5.8]) sentences. The five most prevalent sources were CNN, Fox News, The New York Times, The Guardian, and The Washington Post. There was an overall increase in the number of articles containing the words "headache" or "migraine" from database inception until analysis (1998 up to 2017). The database included no articles containing either "headache" or "migraine" in 1998; in 2016, this number was 1480 articles. CONCLUSIONS: In this longitudinal study, major publications applied a metaphorical use of "headache" about half of the time. The metaphorical use of "headache" is 11-fold greater than the metaphorical use of "migraine" in the same media sample. These depictions may contribute to the trivialization of headache and the stigmatization of individuals with headache disorders. Studies with individuals affected by headache disorders are needed to clarify potential influences.

Activation of ATP-sensitive potassium channels triggers migraine attacks independent of calcitonin gene-related peptide receptors: a randomized placebo-controlled trial.

BACKGROUND: The present study aimed to investigate whether levcromakalim, a KATP channel opener, induces migraine attacks in people with migraine pre-treated with erenumab, a monoclonal CGRP receptor antibody. METHODS: In this double-blind, placebo-controlled, two-way cross-over study, adults with migraine without aura received a subcutaneous injection of 140 mg of erenumab on day 1. Subsequently, they were randomized to receive a 20-minute infusion of 0.05 mg/ml levcromakalim or placebo on two experimental days separated by at least one week (between days 8 and 21). The primary endpoint was the difference in the incidence of migraine attacks between levcromakalim and placebo during the 12-hour post-infusion period. RESULTS: In total, 16 participants completed the study. During the 12-hour observation period, 14 (88%) of 16 participants experienced migraine attacks after levcromakalim, compared to two (12%) after placebo (p < 0.001). The area under the curve for median headache intensity was greater after levcromakalim than placebo (p < 0.001). Levcromakalim elicited dilation of the superficial temporal artery during the first hour after infusion, a response absent following placebo (p < 0.001). CONCLUSIONS: The induction of migraine attacks via opening of KATP channels appears independent of CGRP receptor activation.Trial Registration: ClinicalTrials.gov, Identifier NCT05889442.

Menstrual migraine is caused by estrogen withdrawal: revisiting the evidence.

OBJECTIVE: To explore and critically appraise the evidence supporting the role of estrogen withdrawal in menstrual migraine. MAIN BODY: Menstrual migraine, impacting about 6% of reproductive-age women, manifests as migraine attacks closely related to the menstrual cycle. The estrogen withdrawal hypothesis posits that the premenstrual drop in estrogen levels serves as a trigger of migraine attacks. Despite its wide acceptance, the current body of evidence supporting this hypothesis remains limited, warranting further validation. Estrogen is believed to exert a modulatory effect on pain, particularly within the trigeminovascular system - the anatomic and physiologic substrate of migraine pathogenesis. Nevertheless, existing studies are limited by methodologic inconsistencies, small sample sizes, and variable case definitions, precluding definitive conclusions. To improve our understanding of menstrual migraine, future research should concentrate on untangling the intricate interplay between estrogen, the trigeminovascular system, and migraine itself. This necessitates the use of robust methods, larger sample sizes, and standardized case definitions to surmount the limitations encountered in previous investigations. CONCLUSION: Further research is thus needed to ascertain the involvement of estrogen withdrawal in menstrual migraine and advance the development of effective management strategies to address unmet treatment needs.

Migraine in older adults.

Migraine is an evolving, and sometimes lifelong disorder. The prevalence of episodic migraine peaks among individuals aged in their late 30s, implying a tendency for the disorder to remit with increasing age thereafter, whereas chronic migraine is more likely to persist into later life. Diagnosis and treatment of migraine in older adults, defined as individuals aged 60 years or older, is rendered more complex by increasing probabilities of atypical clinical features and comorbidities, with patients' comorbidities sometimes limiting their therapeutic options. However, the changing clinical presentation of migraine over an individual's lifespan is not well characterised. The neurobiological basis of remission in older adults remains unclear, although vascular, neuronal, and hormonal changes are likely to be involved. Long-term longitudinal studies of individuals with migraine would be particularly informative, with the potential not only to suggest new research directions, but also to lead to the identification of novel therapeutic agents. Although several novel migraine medications are becoming available, their effectiveness, tolerability, and safety often remain uncertain in older adults, who have commonly been excluded from the evaluation of these agents in randomised controlled trials, or who constitute only a small proportion of study populations. There is a need to recognise these limitations in the available evidence, and the specific, and often unmet, clinical needs of older adults with migraine, not least because older adults constitute an increasing proportion of populations worldwide.

Real-world efficacy and tolerability of fremanezumab in adults with chronic migraine: a 3-month, single-center, prospective, observational study.

Background: Following the promising pre-marketing placebo-controlled randomized clinical trials of fremanezumab, post-marketing studies are necessary to verify efficacy and tolerability in various real-world settings. The present study assessed real-world efficacy and safety of fremanezumab. Methods: A 3-month, single-center, prospective, observation study of adults with chronic migraine who were treated with monthly subcutaneous injections of 225 mg fremanezumab in Denmark. The primary outcome was defined as proportion of patients who achieved ≥30% reduction in monthly migraine days (MMDs) from baseline to weeks 9-12. Among secondary outcomes were ≥50 and ≥75% responder rates and the proportion of patients reporting adverse events. Results: A total of 91 patients with chronic migraine were enrolled and received at least one dose of fremanezumab of whom 89 patients (98%) completed the 3-months treatment period. At baseline, the mean (SD) number of monthly headache days was 24.3 ± 5.8 and mean number of MMDs was 18.5 ± 7.4. The number of patients who achieved ≥30% reduction in MMDs from baseline to weeks 9-12 was 58 (65%), while 45 (51%) and 21 (24%) had ≥50 and 75% reduction in MMD, respectively. Twenty-one patients (23%) reported adverse event, in which the most common were constipation (4.4%), fatigue (4.4%) and dizziness (3.3%). No serious adverse events were reported. Conclusion: In adult chronic migraine patients with previous failure of conventional oral migraine preventives, fremanezumab was found to be effective and well-tolerated.

Second messenger signalling bypasses CGRP receptor blockade to provoke migraine attacks in humans.

There are several endogenous molecules that can trigger migraine attacks when administered to humans. Notably, calcitonin gene-related peptide (CGRP) has been identified as a key player in a signalling cascade involved in migraine attacks, acting through the second messenger cyclic adenosine monophosphate (cAMP) in various cells, including intracranial vascular smooth muscle cells. However, it remains unclear whether intracellular cAMP signalling requires CGRP receptor activation during a migraine attack in humans. To address this question, we conducted a randomized, double-blind, placebo-controlled, parallel trial using a human provocation model involving the administration of CGRP and cilostazol in individuals with migraine pretreated with erenumab or placebo. Our study revealed that migraine attacks can be provoked in patients by cAMP-mediated mechanisms using cilostazol, even when the CGRP receptor is blocked by erenumab. Furthermore, the dilation of cranial arteries induced by cilostazol was not influenced by the CGRP receptor blockade. These findings provide clinical evidence that cAMP-evoked migraine attacks do not require CGRP receptor activation. This discovery opens up new possibilities for the development of mechanism-based drugs for the treatment of migraine.

The increasing role of electronic media in headache.

Most individuals with access to the internet use social media platforms. These platforms represent an excellent opportunity to disseminate knowledge about management and treatment to the benefit of patients. The International Headache Society, The European Headache Federation, and The American Headache Society have electronic media committees to promote and highlight the organizations' expertise and disseminate research findings. A growing mistrust in science has made dealing with infodemics (i.e., sudden access to excessive unvetted information) an increasing part of clinical management. An increasing role of these committees will be to address this challenge. As an example, recent studies have demonstrated that the most popular online content on migraine management is not evidence-based and is disseminated by for-profit organizations. As healthcare professionals and members of professional headache organizations, we are obliged to prioritize knowledge dissemination. A progressive social media strategy is associated not only with increased online visibility and outreach, but also with a higher scientific interest. To identify gaps and barriers, future research should assess the range of available information on headache disorders in electronic media, characterize direct and indirect consequences on clinical management, and recognize best practice and strategies to improve our communication on internet-based communication platforms. In turn, these efforts will reduce the burden of headache disorders by facilitating improved education of both patients and providers.

Characterizing healthcare utilization patterns in a Danish population with headache: results from the nationwide headache in Denmark (HINDER) panel.

INTRODUCTION: Worldwide, far from all of those who would benefit make use of headache services, largely because of clinical, social, and political barriers to access. Identifying the factors contributing to low healthcare utilization can generate evidence to guide health policy. Our purpose here is better to characterize healthcare utilization patterns in Denmark. METHODS: The Headache in Denmark (HINDER) study is a nationwide cross-sectional survey of people with headache, conducted using SurveyXact (Rambøll Group A/S, Copenhagen). Healthcare utilization was assessed in a study sample generated by population screening and recruitment. Data collection occurred over two weeks, from September 23rd until October 4th, 2021. The questions enquired into disease characteristics, management, burden, medication intake and healthcare utilization. RESULTS: The number of participants included in the HINDER panel was 4,431, with 2,990 (67.5%: 2,522 [84.3%] female, 468 [15.7%] male; mean age 40.9 ± 11.6 years) completing the survey. One quarter of participants (27.7%) disagreed or strongly disagreed that they were able to manage their headache attacks. Most participants (81.7%) agreed or strongly agreed that their headache was a burden in their everyday lives. The most reported acute medications, by 87.2% of participants, were simple analgesics; of note, 8.6% reported using opioids for their headache. One quarter of participants (24.4%) had never consulted a medical doctor for their headache; one in six (16.5%: more than two thirds of the 24.4%) had never done so despite agreeing or strongly agreeing that their headache was a burden in their everyday lives. Two thirds (65.3%) of participants overall, and almost three quarters (72.4%) of those with weekly headache, had tried one or more complementary or alternative therapies outside conventional medical care. CONCLUSIONS: Our findings are indicative of inadequate delivery of headache care in a country that provides free and universal coverage for all its residents. The implications are twofold. First, it is not sufficient merely to make services available: public education and increased awareness are necessary to encourage uptake by those who would benefit. Second, educational interventions in both pre- and postgraduate settings are necessary, but a prerequisite for these is a resetting of policy priorities, properly to reflect the very high population ill-health burden of headache.

Migraine attacks are of peripheral origin: the debate goes on.

BACKGROUND: Despite the pervasiveness of migraine, the underlying pathophysiological mechanisms initiating migraine attacks are far from well understood and are matter of scientific debate. OBJECTIVE: In this narrative review, we discuss key evidence for that suggest a peripheral origin or central origin and provide directions for future studies that may provide further clarification. DISCUSSION: Migraine pathogenesis is considered to involve the trigeminovascular system, a term that encompasses the trigeminal nerve and its axonal projections to the intracranial blood vessels. Beyond any doubt both peripheral and central mechanisms are involved in migraine pathogenesis, but an unresolved question is the how the initial activation occurs in a migraine attack. Evidence favoring a peripheral origin of migraine attacks, i.e., initial events occur outside of the blood-brain barrier, include the importance of sensitization of perivascular sensory afferents early on in a migraine attack. Evidence favoring a central origin include the occurrence of prodromal symptoms, migraine aura, and activation of structures within the central nervous system early in and during a migraine attack. CONCLUSIONS: Both peripheral and central mechanisms are likely involved in a migraine attack, e.g., peripheral nociceptive input is necessary for pain transmission and cortical activity is necessary for pain perception. Yet, the debate of whether migraine attacks are initiated a peripheral or central site remains unresolved. The increased focus on prodromal symptoms and on the development of a human model of migraine aura will possibly provide key arguments needed to answer this question in the near future. Until then, we cannot draw firm conclusions and the debate goes on.

CGRP-induced migraine-like headache in persistent post-traumatic headache attributed to mild traumatic brain injury.

OBJECTIVE: To ascertain whether intravenous infusion of calcitonin gene-related peptide (CGRP) can induce migraine-like headache in people with persistent post-traumatic headache attributed to mild traumatic brain injury (TBI) and no pre-existing migraine. METHODS: A non-randomized, single-arm, open-label study at a single site in Denmark. Eligible participants were aged 18 to 65 years and had a known history of persistent post-traumatic headache attributed to mild TBI for ≥ 12 months. All participants received continuous intravenous infusion of CGRP (1.5 µg/min) over 20 min. A headache diary was used to collect outcome data until 12 h after the start of CGRP infusion. The primary end point was the incidence of migraine-like headache during 12-hour observational period. RESULTS: A total of 60 participants completed the study protocol and provided data for the analysis of the primary end point. The median age was 32.5 (IQR, 25.5-43.0) years; 43 participants (72%) were female. Following CGRP infusion, 43 (72%) of 60 participants developed migraine-like headache during the 12-hour observational period. The median time to peak headache intensity was 40 min (IQR, 20-60), and the median peak headache intensity was 6 (IQR, 5-8) on the 11-point numeric rating scale. CONCLUSION: Intravenous infusion of CGRP is a potent inducer of migraine-like headache in people with persistent post-traumatic headache attributed to mild TBI. This observation underscores the importance of CGRP in the genesis of migraine-like headache that is often experienced by individuals who are afflicted by persistent post-traumatic headache. Further research is warranted to ascertain whether other signaling molecules also contribute to the disease mechanisms underlying post-traumatic headache.

Cluster headache - The worst possible pain on YouTube.

In clinical practice, patients with cluster headache often ask questions or mention information that they have seen or heard on the Internet. Because YouTube (www.youtube.com) is the second most visited Web site worldwide and offers a plethora of video content, we found it timely to ascertain the quality of information on cluster headache that is freely available on YouTube. We conducted an inquiry on YouTube on January 24, 2022, with the search term "cluster headache." Eligible YouTube videos included those with ≥10,000 views and content related to cluster headache. We assessed the quality and reliability of the videos with the Global Quality Scale and DISCERN, respectively. The search strategy identified 644 videos of which 134 were eligible for inclusion. The sources of the included videos were categorized as "healthcare professional/institution" (n = 45), "personal experience" (n = 52), and "other" (n = 37). According to the Global Quality Scale, 70 (52%) were low quality, 34 (25%) were of moderate quality, and 30 (22%) were of high quality. According to DISCERN, 104 (78%) were of low reliability, 28 (21%) were of moderate reliability, and 2 (1%) were of high reliability. The quality and reliability of cluster headache-related information on YouTube has room for improvement, even the content provided by healthcare providers. These findings should incentivize stakeholders, for example, government services, professional societies, healthcare providers, to provide accessible and better information on cluster headache.

Interest in and exposure to headache disorders among neurology residents in Denmark: A nationwide cross-sectional survey.

OBJECTIVE: Headache disorders constitute a leading cause of disability worldwide, but there is a consistent absence of awareness and educational activities for healthcare providers across regions. Thus, we found it timely to identify potential structural challenges and factors that may affect acquisition of knowledge of headache disorders and their management during their 4-year residency. MATERIALS & METHODS: We conducted a nationwide cross-sectional survey of residents in neurology in Denmark including, but not limited to, questions on interest in neurological subspecialties and disorders, adequacy of training in headache disorders, exposure to headache disorders during training including time spent on headache disorders, exposure to specialist outpatient clinics, whether their hospital have a tertiary headache clinic, training in specific procedures (anesthetic blockade, e.g., greater occipital nerve blockade, and onabotulinumtoxinA for headache), and an estimate of proportion of cases with headache among patients managed in the last week. RESULTS: The survey was distributed to 127 residents in Denmark between March 2022 and April 2022. Of these, 59 (47%) completed all questions of the survey. Headache disorders were the fourth most popular subspecialties among respondents (n = 15 [25%]) following movement disorders (n = 27 [46%]), vascular neurology (n = 26 [44%]), and neuromuscular disorders (n = 25 [42%]). The mean number of hours spent in a course or a structured educational activity in headache disorders during residency was 12.1 h. Half of respondents (n = 27 [46%]) reported that they perceived their training in headache disorders to be inadequate. CONCLUSIONS: Even in Denmark, a country with excellent headache services, half of residents in neurology report an inadequate training despite a higher-than-average number of hours of structured educational activities. These findings should incentivize stakeholders to make structural changes to improve education in headache disorders during the most fundamental years of training.
