Meta-Synthesis on Migraine Management

Internal stigmatization in patients with chronic migraine and medication overuse headache

OBJECTIVES

Internalized stigma can have profound effects on how individuals with migraines and other primary headache disorders see themselves and their quality of life. We aimed to investigate internalized stigma in patients with chronic migraines and medication overuse headaches.

METHODS

A total of 57 patients (52 women, 5 men) were included in the study, 26 of these patients were affected by chronic migraine, 31 of them were affected by medication overuse headache and chronic migraine. The Internalized Stigma Scale in Mental Illness (Ristsher's stigmatization scale) and General Health Questionnaire were applied to all patients.

RESULTS

In Ristsher's stigmatization scale, which measures internalization of stigma, internalized stigmatization was more significant in patients with medication overuse headache than in patients with chronic migraine compared to groups (p:0.05). The subtitle of alienation was statistically significant when the groups were compared to all subscales in the form of alienation, confirmation of stereotypes, perceived discrimination, social withdrawal and resistance to stigma (p:0.05).

DISCUSSION

Although internal stigmatize has been observed in chronic migraine patients, medication overuse headache is also a type of headache with intense stigma. In addition, this internal stigma perhaps plays an active role in the transformation of chronic migraine patients to medication overuse headaches patient.

Living with migraine: A meta-synthesis of qualitative studies

Introduction

Migraine is one of the top ten causes of disability worldwide. However, migraine is still underrated in society, and the quality of care for this disease is scant. Qualitative research allows for giving voice to people and understanding the impact of their disease through their experience of it. This study aims at synthesising the state of the art of qualitative studies focused on how people with migraine experience their life and pathology.

Methods

MEDLINE via PubMed, EMBASE, CINAHL, PsycINFO, and Cochrane Library were consulted up to November 2021 for qualitative studies. Studies to be eligible had to focus on adults (age > 18 years) with a diagnosis of primary episodic or chronic migraine following the International Classification of Headache. The quality of the study was analysed using the CASP (Critical Appraisal Skills Programme) tool. The synthesis was done through a thematic analysis. CERQual (Confidence in Evidence from Reviews of Qualitative research) approach was used to assess the confidence in retrieved evidence.

Results

Ten studies were included, counting 262 people with migraine. Our synthesis produced four main themes. (1) “Negative impact of migraine symptoms on overall life” as migraine negatively impacts people's whole life. (2) “Impact of migraine on family, work and social relationship” as migraine reduces the possibility to focus at work and interact with people. (3) “Impact of migraine on emotional health” as people with migraine experience psychological distress. (4) “Coping strategies to deal with migraine” such as keep on living one's own life, no matter the symptoms.

Conclusions

Migraine negatively impacts people's whole life, from private to social and work sphere. People with migraine feel stigmatised as others struggle with understanding their condition. Hence, it is necessary to improve awareness among society of this disabling condition, and the quality of care of these people, tackling this disease from a social and health-policy point of view.

Societal and personal impact of migraine

Migraine is one of the main causes of years lived with disability (YLDs) worldwide, as showed in the Global Burden of Diseases Study. Its influence on patients' life is relevant and pervasive, with a specific impact on social, family, and work functioning, considering that migraine mainly affects adults under the age of 50. Several studies demonstrated that relations inside the family as well as in every social context are negatively influenced by migraine. According to the results of studies and surveys from different countries, patients' daily activities are often limited during migraine attacks, particularly in terms of performance in social and domestic activities and in terms of reduced productivity in work and school duties. Also an interictal burden is present. Migraineurs are conditioned by the fear of the next attack, often suffer from comorbid conditions such as anxiety and depression, and are subject to different forms of stigma. Consequently, migraine implies relevant costs for the individuals and for society, with higher figures for indirect costs (related to reduced participation and to limited productivity) than indirect costs (related to drugs, medical visits, examinations, and hospitalization).

Real-world experience of OnabotulinumtoxinA treatment in female patients with chronic migraine: a qualitative study using in-depth interviews

BACKGROUND

Chronic migraine (CM) causes great disability and affects an individual's quality of life. OnabotulinumtoxinA (OBT-A, Botox®) was the first prophylactic treatment specifically indicated for CM. The aim of this study was to describe the experiences of women with CM treated with OBT-A.

MATERIALS AND METHODS

The study design is a qualitative descriptive study. A purposeful sampling of 30 women (mean age, 42.7; standard deviation, 10.6) who had received at least two administrations of OBT-A for CM (PREEMPT protocol) was performed. Data collection included in-depth interviews and researchers' field notes. A thematic analysis was carried out according to qualitative research guidelines.

RESULTS

Five themes were identified: (a) A long way to go before Botox®, (b) First time hearing about the treatment and its expectations, (c) The administration of Botox®, (d) Treatment effects, and (e) Follow-up. Patients described a long history of treatment failures prior to the start of OBT-A treatment. Information about this migraine treatment came from the neurologist; following the information, patients had high expectations, including unrealistic expectations regarding the onset and duration of effect. They acknowledged fear of the injections and some discomfort due to the procedure. With treatment, participants reported better migraine control and an improvement in their quality of life. Follow-up had some barriers, such as delayed appointments for subsequent doses, but also strengths, such as effectiveness and few side effects.

CONCLUSIONS

Qualitative research offers insight into how patients with CM experience treatment with OBT-A. Our results highlight some relevant aspects that should be considered when providing OBT-A treatment.

Patient-identified burden and unmet needs in patients with cluster headache: An evidence-based qualitative literature review

Objectives:

To qualitatively identify evidence-based literature related to the daily burden and unmet treatment and psychosocial needs of patients with cluster headache (CH).

Methods:

A literature search was conducted through October 20, 2020 across MEDLINE, EMBASE, CINAHL, and PsychInfo databases exploring quality of life (QoL) and disease burden in adults with CH. The search was restricted to full-text reports in peer-reviewed journals. Methodologic quality was assessed using the Critical Skills Appraisal Program.

Results:

From 11 identified publications, QoL was reduced in persons living with CH, with significant psychological, social, and socio-economic burdens, and work-related disability. The CH disease trajectory is complex, with patients experiencing the impact of their disease across multiple domains beyond the biological manifestation of the disease including stigma, employment limitations, and suicidal ideation, and with a lack of effective treatment from the patient perspective.

Discussion:

These findings strengthen comprehension of the CH patient experience, enabling a deeper understanding of the patients’ perspective and experience of their disease andunmet needs, providing a basis for future research into this debilitating condition. Minor limitations of this study include data extraction and study selection biases.

Migraine History and Outcomes in Military Pilots and Flight Surgeons

BACKGROUND: Migraine is a common disorder with significant aeromedical implications. The variability and unpredictable nature of occurrences hampers accurate assessment of future risk. This uncertainty results in a necessarily conservative approach to aeromedical recommendations, which unfortunately may lead to over-restrictive dispositions. Limited long-term follow up information is available on migraine outcomes in pilots, particularly assessing for impact of potential modifiable aggravating factors.Methods: This retrospective study reviewed 159 U.S. Air Force pilots with migraine who had been granted aeromedical waivers. As a comparison group, 44 U.S. Air Force flight surgeons with migraine who had been granted aeromedical waivers were reviewed.Results: Migraine with aura and isolated migraine aura without headache accounted for the majority of migraine subtypes in both male and female subjects. Self-identified triggering factors were identified by 62% of subjects. The most commonly reported triggers were dietary factors, sleep disturbances, stress, caffeine intake, and hormonal factors. Sleep disturbances, stress, hormonal factors, and ethanol triggers were more frequently noted in female subjects. Self-reported positive response to trigger factor modification was noted in 54% of subjects. Subjects reported an average of only 3 migraine attacks in the previous year. Long-term follow up indicated continued aeromedical waiver in 91% of subjects.Discussion: The majority of subjects had migraine with aura or isolated migraine aura. Significant salutary response to modification of commonly-reported triggering factors was noted. These findings can be incorporated into individualized aeromedically-compatible management strategies to clarify symptom impact on aviation safety, improve symptom control, and increase the possibility of safe return to fly recommendations.Hesselbrock RR, Haynes JT.

Neuroscience Education as Therapy for Migraine and Overlapping Pain Conditions: A Scoping Review

BACKGROUND

Neuroscience Education Therapy (NET) has been successfully used for numerous overlapping pain conditions, but few studies have investigated NET for migraine.

OBJECTIVE

We sought to (1) review the literature on NET used for the treatment of various pain conditions to assess how NET has been studied thus far and (2) recommend considerations for future research of NET for the treatment of migraine.

DESIGN/METHODS

Following the PRISMA guideline for scoping reviews (PRISMA-ScR) Co-author (TR), a Medical Librarian, searched the MEDLINE, PsychInfo, Embase & Cochrane Central Clinical Trials Registry databases for peer-reviewed articles describing NET to treat migraine and other chronic pain conditions. Each citation was reviewed by two trained independent reviewers. Conflicts were resolved through consensus.

RESULTS

Overall, a NET curriculum consists of the following topics: pain does not equate to injury, pain is generated in the brain, perception, genetics, reward systems, fear, brain plasticity, and placebo/nocebo effects. Delivered through individual, group, or a combination of individual and group sessions, NET treatments often incorporate exercise programs and/or components of other evidence-based behavioral treatments. NET has significantly reduced catastrophizing, kinesiophobia, pain intensity, and disability in overlapping pain conditions. In migraine-specific studies, when implemented together with traditional pharmacological treatments, NET has emerged as a promising therapy by reducing migraine days, pain intensity and duration, and acute medication intake.

CONCLUSION

NET is an established treatment for pain conditions, and future research should focus on refining NET for migraine, examining delivery modality, dosage, components of other behavioral therapies to integrate, and migraine-specific NET curricula.

Survey of Pain Medicine Specialists' Familiarity with Migraine Management

OBJECTIVE

Pain specialists treat patients with headache and interface with those who use opioids more so than neurologists and headache specialists. We assessed headache medicine knowledge and needs of pain specialists.

DESIGN/SETTING

Cross-sectional online survey.

SUBJECTS

Members of the American Academy of Pain Medicine.

METHODS

Survey was based on a prior survey on primary care providers' knowledge and needs and was iteratively updated by four headache specialists, two with pain medicine affiliations.

RESULTS

Of the 105 respondents, 71.4% were physicians, 34.3% were women, and they averaged 20.0 ± 13.6 years in practice. The most common specialty was anesthesia (36.1%, n = 35/97) followed by neurology (14.4%, n = 14/97). About half of providers (55.7%, n = 34/61 and 53.3%, n = 32/60) were familiar with the American Academy of Neurology Guidelines for pharmacological migraine prevention and the Choosing Wisely Campaign recommendations for limiting neuroimaging and opioids. Less than half of all providers (39.7%, n = 23/58) were familiar with the American Headache Society guidelines for emergency management of migraine. Providers were aware of Level A evidence-based nonpharmacological therapies, with over three-fourths recognizing cognitive behavioral therapy (80.7%, n = 50/62) and biofeedback (75.8%, n = 47/62) as evidence-based interventions. About 80% of providers (n = 50/64) estimate making migraine diagnoses in ≤ 50% of their patients with headache. Providers consider starting preventive headache therapy at 7.1 ± 3.9 days/month and report referring 34.3%±34.2% of patients to behavioral interventions.

CONCLUSIONS

Dissemination and implementation of headache guidelines is needed for pain medicine specialists. Providers may need help diagnosing migraine based on currently accepted guidelines and referring for evidence-based behavioral therapies.

Stigma and Migraine: Developing Effective Interventions

PURPOSE OF REVIEW

Migraine and other primary headache disorders do not receive adequate research funding, medical resources, or other forms of structural support relative to their prevalence and the disability they cause. In recent research, scholars have argued that stigma associated with headache disorders explains some of this discrepancy. This review will discuss (1) the factors contributing to stigma toward migraine and other primary headache disorders, (2) how structural and enacted stigma may perpetuate individual disability, (3) the impact of internalized stigma, and (4) interventions to mitigate stigma toward headache disorders with an emphasis on outcome monitoring. The review will also propose new areas of stigma research in need of further investigation.

RECENT FINDINGS

Recent research shows that discrimination can exacerbate chronic pain. Stigma profoundly affects everything from the allocation of federal research funds and healthcare resources to individual patients' self-efficacy and ability to care for themselves. Understanding the stigma of migraine and learning how to develop effective interventions to mitigate this stigma will increase access to appropriate migraine care, improve healthcare providers' ability to care for their migraine patients, and help advocates reverse policies that discriminate against those with migraine. It is important to closely monitor outcomes of anti-stigma efforts for both positive and negative consequences and take note of outcomes and "lessons learned" from anti-stigma campaigns for other diseases.

Focus group findings on the migraine patient experience during research studies and ideas for future investigations

OBJECTIVES

We conducted focus groups in people who had participated in mobile health (mHealth) studies of behavioral interventions for migraine to better understand: (a) Participant experience in the recruitment/enrollment process; (b) participant experience during the studies themselves; (c) ideas for improving participant experience for future studies.

METHODS

We conducted four focus groups in people who had agreed to participate in one of three studies involving mHealth and behavioral therapy for migraine. Inclusion criteria were being age 18-80, owning a smartphone, and having four or more headache days per month. All participants met the International Classification of Headache Disorders third edition beta version criteria for migraine. Exclusion criteria were not speaking English and having had behavioral therapy for migraine in the past year. Focus groups were audio recorded, fully transcribed and coded using general thematic analysis.

RESULTS

The 12 focus group participants had a mean age of 45 ± 15, a mean age of headache onset of 21 ± 13 and mean MIDAS disability score was 39 ± 56. Participants were women (100%), white (50%), Asian (33.3%) or members of other racial groups (16.7%). Certain themes emerged from each topic area. With regard to recruitment/enrollment (a), key themes were: (i) Participants joined their study out of an interest in research and/or a desire to try a new migraine treatment modality (behavioral therapy). (ii) Enrollment should be simple and study requirements should be carefully explained prior to enrollment. When asked about their experiences during the studies (b), the following themes emerged: (i) It is difficult to participate in study follow-up and compliance phone calls; (ii) participants prefer to choose from among various options for contact with the study team; (iii) there are barriers that limit app use related to migraine itself, as well as other barriers; (iv) completing diaries on a daily basis is challenging; (v) technical difficulties and uncertainties about app features limit use; (vi) being part of a research study promoted daily behavioral therapy use; (vii) progressive muscle relaxation (PMR) is enjoyable, and has a positive impact on life; (viii) behavioral therapy was a preferred treatment to reduce migraine pain. Ideas for improving study design or patient experience (c) included: (i) Increased opportunity to interact with other people with migraine would be beneficial; (ii) navigating the app and data entry should be easier; (iii) more varied methods for viewing the data and measures of adherence are needed; (iv) more information on and more varied behavioral treatment modalities would be preferred.

CONCLUSION

Though people with migraine are motivated to participate in mHealth and behavioral treatment studies, better communication up front about interventions as well as greater flexibility in interventions and follow-up methods are desired.

Quality of life of migraine patients followed in neurology clinics in Riyadh, Saudi Arabia

BACKGROUND

Migraine is a chronic disorder that negatively affects a patient's quality of life (QOL). As little is known about the QOL of migraine sufferers in Saudi Arabia, our aim was to investigate the QOL and the level of migraine-associated disability of migraine patients.

MATERIALS AND METHODS

This cross-sectional study was conducted in neurology clinics at King Abdulaziz Medical City for National Guard and Prince Sultan Military Medical City in Riyadh, Saudi Arabia, from August to December 2018. The migraine-specific QOL questionnaire (MSQ), version 2.1, was used to measure restrictive, preventive, and emotional domains. The sum of the item responses ranged between 0 and 100, with higher scores indicating better QOL. A descriptive analysis of numerical variables was reported in terms of means and standard deviation, while categorical variables were described using frequencies and percentages.

RESULTS

A total of 300 migraine patients completed the questionnaire; 67% were females. Age of participants ranged from 20 to 53 years, with mean age of 34.21 (SD=7.26). The mean score in the QOL restrictive domain was 51.8 ± 19, whereas the mean scores for preventive and emotional domains were 54 ± 18 and 46.3 ± 23.4, respectively. Low QOL scores were associated with young ages, long disease duration, frequent migraine attacks, and presence of chronic diseases.

CONCLUSION

Chronic migraine has a negative impact on QOL, predominantly in young patients, patients with frequent attacks, those not using preventive medications, and those suffering from chronic diseases.

Nonpharmacological Interventions Addressing Pain, Sleep, and Quality of Life in Children and Adolescents with Primary Headache: A Systematic Review

Purpose

Children and adolescents with primary headache are at risk of persistent somatic symptoms and reduced quality of life (Qol) due to pain and pain-related behaviors, such as avoiding school and activities. Sleep is essential to health, and children and adolescents with primary headaches have more sleep complaints than do healthy controls. A treatment approach that addresses multifactorial causes is likely important. Nonpharmacological interventions seem promising. However, knowledge about effective strategies is limited. The objective of this review is to assess the effect of nonpharmacological interventions in randomized controlled trials (RCTs) among children and adolescents with primary headache in order to identify useful strategies.

Patients and methods

Outcome measures are pain, sleep, Qol, and coping versus no intervention or control intervention. Medline, CINAHL, EMBASE, and PsycINFO were searched for eligible trials. ClinicalTrials.gov. was searched for ongoing trials. Initial searches yielded 2588 publications. After initial screening and subsequent full-text review and quality assessment, 13 RCTs reported in 15 articles were selected for review. All reviewers independently assessed study quality using the CONSORT criteria for nonpharmacological interventions.

Results

Cognitive behavioral therapy (CBT), including education on pain-related topics, sleep, coping, and stress management, is an effective strategy for reducing headache and pain within groups over time. Fifteen studies assessed pain, 3 studies assessed sleep, 6 studies assessed Qol, and 11 studies assessed coping.

Conclusion

Strategies identified as useful were parts of CBT interventions. However, it was not possible to identify a single effective intervention addressing pain, sleep, Qol, and coping in children and adolescents with headache, primarily because sleep was infrequently addressed. Various aspects of Qol and coping strategies were assessed, rendering comparison difficult. Strategies for future interventions should include descriptions of theory-driven CBT interventions, depending on clinical setting and based on local resources, to promote a solid evidence base for nonpharmacological interventions.

Current Status of Antiepileptic Drugs as Preventive Migraine Therapy

BACKGROUND

Antiepileptic drugs (AEDs) are an important class of agents used in the treatment of migraine, a neurological disorder that imparts significant socioeconomic burden. It is important for neurologists to understand the rationale for AEDs in migraine-preventive treatment, as well as each agent's efficacy and tolerability profile, in order to best determine clinical care.

PURPOSE OF THIS REVIEW

This article specifically provides the following: (1) a review of the mechanism of action, efficacy, and tolerability of topiramate and divalproex sodium/sodium valproate, the most widely used AEDs for migraine prevention, (2) a discussion on emerging evidence regarding the efficacy of zonisamide and levetiracetam, and (3) comments on gabapentin, pregabalin, carbamazepine, oxcarbazepine, and lamotrigine, AEDs which have insufficient evidence for use in migraine prevention.

RECENT FINDINGS

The potential role for new extended-release formulations of topiramate in migraine prevention is discussed. There is substantial evidence supporting the use of AEDs in migraine prevention. Specific agents should be chosen based on their efficacy and tolerability profiles. Further studies are needed to determine the efficacy of the newer AEDs, zonisamide and levetiracetam, in migraine prevention and to clarify the role of gabapentinoids in headache management.
