RESUMO

OBJECTIVE: To assess for improvement in comfort in participating in advocacy for migraine and headache disorders and knowledge needed for successful advocacy. BACKGROUND: The Advocacy Connection Team (ACT)-Now program is an educational program offered through Miles for Migraine, a non-profit advocacy organization. It is designed to teach headache fellows and patients advocacy skills. METHODS: In a cross-sectional pre-test-post-test design, the 2021 ACT-Now cohort of 98 participants were administered a set of 11 pre-course survey questions identifying their role (healthcare provider/headache fellow or patient/caregiver), baseline knowledge of migraine-related disability and stigma, and baseline engagement and comfort with advocating. The post-course survey questions were the same as the pre-course questions, with the addition of one question assessing knowledge of migraine-related disability, additional questions addressing comfort levels advocating with insurance and policymakers, as well as creating an advocacy plan. RESULTS: For the pre-course survey, 69 participants responded and for the post-course survey, 40 participants responded. Compared to the pre-course survey, participants were able to correctly identify epidemiological data about migraine following the ACT-Now course (pre-course 46% correct, post-course 58% correct, p = 0.263). There was also an increase in the comfort level of participants in advocacy activities, including the creation of an advocacy action plan (pre-course 23% were "very comfortable" advocating, post-course 63%, p < 0.05). CONCLUSION: These results demonstrate that ACT-Now is effective at improving advocacy skills in a mixed cohort of patients and headache fellows, giving them the skills to create advocacy plans and engage with other patients and physicians, payers, and policymakers to create a more understanding, equitable and compassionate world for persons with migraine and other headache diseases.

RESUMO

PURPOSE OF REVIEW: To review carnitine's role in migraine and headache, present a case of a patient with intractable chronic migraine refractory to medications but exquisitely responsive to mitochondrial cofactors with a particularly prompt response to L-carnitine supplementation with dose response, and suggest scenarios where L-carnitine could be considered for prophylactic treatment in migraine and intractable headache with migraine features. RECENT FINDINGS: Multiple treatments modalities are used to treat migraine, including nutraceutical therapies. Mitochondrial supplements are often used to treat migraine, based on controlled trials. One of the nutraceutical therapies used in neurological and non-neurological conditions is L-carnitine. A few studies have examined the effect of carnitine in patients with migraine. We present a case of a patient with chronic migraine-like headaches found to have carnitine deficiency whose headaches greatly improved with carnitine supplementation. This case suggests that secondary carnitine deficiency may cause chronic migraine. Energy deficiency states occur with migraine, and replenishment of energy substrates has demonstrated some improvement in migraine. Recent studies suggest that L-carnitine with other mitochondrial cofactors may be migraine preventives. The exact link between carnitine and migraine is unknown. Perhaps carnitine deficiency should be in the differential for refractory migraine. Supplementation with L-carnitine merits exploration as a nutraceutical treatment of chronic migraine. Our case suggests that there may be a dose-dependent response to L-carnitine.

RESUMO

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.

RESUMO

BACKGROUND: Triptans are the most commonly prescribed acute treatments for migraine; however, not all triptan users experience adequate response. Information on real-world resource use and costs associated with triptan insufficient response are limited. METHODS: A retrospective claims analysis using US commercial health plan data between 2012 and 2015 assessed healthcare resource use and costs in adults with a migraine diagnosis newly initiating triptans. Patients who either did not refill triptans but used other non-triptan medications or refilled triptans but also filled non-triptan medications over a 24-month follow-up period were designated as potential triptan insufficient responders. Patients who continued filling only triptans (i.e. triptan-only continuers) were designated as potential adequate responders. All-cause and migraine-related resource use and total (medical and pharmacy) costs over months 1-12 and months 13-24 were compared between triptan-only continuers and potential triptan insufficient responders. RESULTS: Among 10,509 new triptan users, 4371 (41%) were triptan-only continuers, 3102 (30%) were potential triptan insufficient responders, and 3036 (29%) did not refill their index triptan or fill non-triptan medications over 24 months' follow-up. Opioids were the most commonly used non-triptan treatment (68%) among potential triptan insufficient responders over 24 months of follow-up. Adjusted mean all-cause and migraine-related total costs were $5449 and $2905 higher, respectively, among potential triptan insufficient responders versus triptan-only continuers over the first 12 months. CONCLUSIONS: In a US commercial health plan, almost one-third of new triptan users were potential triptan insufficient responders and the majority filled opioid prescriptions. Potential triptan insufficient responder patients had significantly higher all-cause and migraine-related healthcare utilization and costs than triptan-only continuers.

RESUMO

Migraine is a prevalent disease with a substantial socioeconomic impact. However, stigma affects social attitude toward migraine, accruing additional burden on individuals with migraine and isolating them from a society that should be supporting them. PURPOSE OF THIS REVIEW: This review will discuss the following concepts: (1) the emergence of stigma toward migraine and its impact on medical care; (2) internalized stigma among those with migraine and its detrimental effect on quality of life and patient-physician relationships; (3) the structural impact of stigma on research funding, workplace support, and specialized care; and (4) strategies for "rebranding" the disease and alleviating stigma toward migraine. RECENT FINDINGS: Recent literature on condition rebranding offers strategies on how to define and communicate migraine to the public. Rebranding of migraine to alleviate societal stigma is paramount. This involves use of unified language, education, and advocacy.

RESUMO

BACKGROUND: OnabotulinumtoxinA is effective in preventing chronic migraine (CM); however, the benefit of onabotulinumtoxinA in patients with CM with daily headache is unknown because these patients are typically excluded from clinical trials. This subanalysis of the COMPEL Study assessed the efficacy and safety of onabotulinumtoxinA in people with CM with and without daily headache. METHODS: In total, 715 patients received onabotulinumtoxinA 155 U with or without concomitant oral preventive treatment. Patients who had complete daily diary records for the 28 days of the baseline period were stratified based on daily headache status. The primary outcome variable was reduction in headache-day frequency per 28-day period at 108 weeks (after 9 treatment cycles) relative to baseline. Exploratory outcomes included moderate to severe headache days, migraine disability (using the Migraine Disability Assessment [MIDAS] questionnaire), and health-related quality of life (Migraine-Specific Quality-of-Life Questionnaire v2 [MSQ]). Adverse events and their relatedness were recorded. RESULTS: Overall, 641 patients had complete daily diary records at baseline. In patients with daily headache (n = 138) versus without (n = 503), treatment with onabotulinumtoxinA was associated with a significant mean (SD) reduction in 28-day headache-day frequency relative to baseline at week 108 (- 10.5 [9.2] vs - 12.2 [6.7], respectively; both P < 0.001) with no significant between-group difference (P = 0.132). The mean (SD) reduction in moderate to severe headache days at week 108 was significant in patients with and without daily headache (- 11.5 [9.4] and - 9.9 [6.4]; P < 0.001) with no significant between-group difference (P = 0.153). Mean (SD) MIDAS scores significantly improved from baseline at week 108 (- 43.3 [73.4] and - 43.6 [46.7]; both P < 0.001), with no significant between-group difference (P = 0.962). Similarly, mean (SD) MSQ subscale scores significantly improved from baseline at week 108 for patients with and without daily headache. OnabotulinumtoxinA was well tolerated in patients with and without daily headache. CONCLUSION: Results indicate that onabotulinumtoxinA is associated with reductions from baseline in headache-day frequency and improvements in disability and quality of life for up to 108 weeks in people with CM with daily headache; however, a longer duration of treatment was required to fully realize the treatment effect on headache. No new safety concerns were identified.

RESUMO

BACKGROUND: OnabotulinumtoxinA is effective in treating chronic migraine (CM), but there are limited data assessing how allodynia affects preventive treatment responses. This subanalysis of the 108-week, multicenter, open-label COMPEL Study assessed the efficacy and safety of onabotulinumtoxinA in people with CM with and without allodynia. METHODS: Patients (n = 715) were treated with onabotulinumtoxinA 155 U every 12 weeks for 9 treatment cycles. The Allodynia Symptom Checklist was used to identify patients with allodynia (scores ≥3). The primary outcome for this subanalysis was reduction in monthly headache days from baseline for weeks 105 to 108 in groups with and without allodynia. Other outcomes included assessments of moderate to severe headache days, disability (using the Migraine Disability Assessment [MIDAS] questionnaire), and health-related quality of life (Migraine-Specific Quality-of-Life Questionnaire [MSQ] v2). Adverse events and their relation to treatment were recorded. RESULTS: OnabotulinumtoxinA was associated with a significant mean (SD) reduction in headache day frequency at week 108 relative to baseline in patients with (n = 289) and without (n = 426) allodynia (- 10.8 [7.1] and - 12.5 [7.4], respectively; both P < 0.001) that was significantly greater in patients without allodynia (P = 0.044 between-subgroup comparison). Moderate to severe headache days were significantly reduced at week 108 in patients with and without allodynia (- 9.6 [6.9] and - 10.5 [7.2]; both P < 0.001); reduction was similar between groups. MIDAS scores improved significantly at week 108 (- 53.0 [50.3] and - 37.7 [53.0]; both P < 0.001), with a significant between-group difference in favor of those with allodynia (P = 0.005). Similarly, MSQ subscale scores (Role Function Preventive, Role Function Restrictive, Emotional Function) significantly improved at week 108 for patients with and without allodynia: 20.6 (21.9) and 16.9 (20.7), 28.0 (23.3) and 24.7 (22.7), and 27.6 (26.5) and 24.9 (26.1), respectively (all P < 0.001). OnabotulinumtoxinA was well tolerated in patients with and without allodynia. CONCLUSION: Results indicate that onabotulinumtoxinA is associated with reductions from baseline in multiple efficacy outcomes for up to 108 weeks whether or not allodynia is present. The allodynia group showed a smaller treatment response for reduction in headache days, but a similar or greater treatment response for improvement in other measures. No new safety concerns were identified.

RESUMO

BACKGROUND: Dual supraorbital and occipital nerve stimulation (SONS and ONS) have shown promising efficacy in treating primary headaches. However, its functional outcome is not well studied. OBJECTIVE: To present functional outcome studies of combined SONS and ONS for chronic migraine using verified metrics. METHOD: Consecutive patients with both SONS and ONS assessed with Migraine Disability Assessment (MIDAS) and Beck Depression Index (BDI) both preoperatively and postoperatively were studied. Selected predictor variables included patients with ≥50% improvement of pain, disability status, number of years from diagnosis to implantation, and narcotic use. Functional outcome variables included net improvement of ranked MIDAS and BDI scores. Multivariate analysis of variance was performed to assess the correlation between the outcome and predictor variables. RESULTS: Sixteen patients (12 female; average age 52 years old) were studied. Follow-up ranged from 5 to 80 months (average 44.5; σ = 21.4 months). At most recent follow-up, eight patients had a positive response (≥50% improvement in headache), which was the only predictor of functional outcome (total MIDAS, MIDAS-B, and BDI) (p = 0.021). Of note, improvement in functional outcome was only significant during the perioperative 3-6 months period and not throughout long-term follow-up. Among the predictor variables, a strong inverse correlation was found between disability status and positive response to stimulation (r = -0.582). CONCLUSION: There is a paucity of studies in quality of life, productivity, and psychosocial aspects with peripheral nerve stimulation therapy for headache. Patients with a positive response to SONS and ONS also reported overall improvement in their functional status as reflected by MIDAS and BDI in the perioperative period. Unfortunately, this effect waned over the long-term follow-up.

RESUMO

Occipital nerve stimulation may be effective in treating chronic migraine. Six studies, including three double-blind studies, were performed, with five showing evidence of benefit. However, of the three randomized, controlled trials, none has met a primary endpoint successfully. A separate study suggested a benefit for combined supraorbital and greater occipital nerve stimulation.

RESUMO

OBJECTIVE: The objective of this pilot study is to evaluate the effects of daily duloxetine, 60-120 mg, on the frequency, duration, and severity of migraine attacks and the level of disability in episodic migraineurs. BACKGROUND: There is a need for more proven effective migraine preventive medications. Two antidepressants, both of which block serotonin and norepinephrine reuptake, have been shown to be effective in the preventive treatment of migraine. Neither has earned a level A recommendation in the 2012 guidelines of the American Academy of Neurology. Duloxetine also blocks serotonin and norepinephrine reuptake. METHODS: This was a prospective, 5-visit study on duloxetine treatment of episodic migraine headache with 4-10 migraine days, and less than 15 headache days per month. Patients were titrated to a goal dose of 120 mg. They were excluded if they had depression. RESULTS: There were 22 completers plus 5 subjects who took at least 1 dose of drug. The mean duloxetine dose was 110 mg. In a modified intent-to-treat analysis, subjects went from 9.2 ± 2.7 headache days per month at baseline to 4.5 ± 3.4 headache days per month (P < .001). There were no significant differences in the average headache duration, average headache severity, maximum headache attack severity, and level of functioning. Fifty-two percent of subjects had a 50% or greater improvement in headache days. CONCLUSIONS: Migraine prophylactic treatment with high-dose duloxetine may be effective in a nondepressed individual. The reported treatment response is in line with other commonly used migraine preventives.

RESUMO

OBJECTIVE: To describe a standardized methodology for the performance of peripheral nerve blocks (PNBs) in the treatment of headache disorders. BACKGROUND: PNBs have long been employed in the management of headache disorders, but a wide variety of techniques are utilized in literature reports and clinical practice. METHODS: The American Headache Society Special Interest Section for PNBs and other Interventional Procedures convened meetings during 2010-2011 featuring formal discussions and agreements about the procedural details for occipital and trigeminal PNBs. A subcommittee then generated a narrative review detailing the methodology. RESULTS: PNB indications may include select primary headache disorders, secondary headache disorders, and cranial neuralgias. Special procedural considerations may be necessary in certain patient populations, including pregnancy, the elderly, anesthetic allergy, prior vasovagal attacks, an open skull defect, antiplatelet/anticoagulant use, and cosmetic concerns. PNBs described include greater occipital, lesser occipital, supratrochlear, supraorbital, and auriculotemporal injections. Technical success of the PNB should result in cutaneous anesthesia. Targeted clinical outcomes depend on the indication, and include relief of an acute headache attack, terminating a headache cycle, and transitioning out of a medication-overuse pattern. Reinjection frequency is variable, depending on the indications and agents used, and the addition of corticosteroids may be most appropriate when treating cluster headache. CONCLUSIONS: These recommendations from the American Headache Society Special Interest Section for PNBs and other Interventional Procedures members for PNB methodology in headache disorder treatment are derived from the available literature and expert consensus. With the exception of cluster headache, there is a paucity of evidence, and further research may result in the revision of these recommendations to improve the outcome and safety of these interventions.

RESUMO

Medical language has implications for both public perception of and institutional responses to illness. A consensus panel of physicians, academics, advocates, and patients with diverse experiences and knowledge about migraine considered 3 questions: (1) What is migraine: an illness, disease, syndrome, condition, disorder, or susceptibility? (2) What ought we call someone with migraine? (3) What should we not call someone with migraine? Although consensus was not reached, the responses were summarized and analyzed quantitatively and qualitatively. Panelists participated in writing and editing the paper. The panelists agreed that "migraine," not "migraine headache," was generally preferable, that migraine met the dictionary definition for each candidate moniker, terms with psychiatric valence should be avoided, and "sufferer" should be avoided except in very limited circumstances. Overall, while there was no consensus, "disease" was the preferred term in the most situations, and illness the least preferred. Panelists disagreed strongly whether one ought to use the term "migraineur" at all or if "person with migraine" was preferable. Panelists drew upon a variety of principles when considering language choices, including the extent to which candidate monikers could be defended using biomedical evidence, the cultural meaning of the proposed term, and the context within which the term would be used. Panelists strove to balance the need for terms to describe the best science on migraine, with the desire to choose language that would emphasize the credibility of migraine. The wide range of symptoms of migraine and its diverse effects may require considerable elasticity of language.

RESUMO

Primary headache disorders are generally characterized by the pain, time course, and associated symptoms of their attacks, but often are accompanied by milder interictal pain. Patients with chronic migraine, chronic tension-type headache, hemicrania continua, and new daily-persistent headache have constant pain more often than not. Patients with trigeminal autonomic cephalalgias such as cluster headache commonly have interictal pain as well, usually much milder and unilateral to the side of attacks. Even those with rare headache types, including hypnic headache and trigeminal neuralgia, commonly have interictal pain. This review describes the incidence of interictal pain in primary headache disorders and suggests the significance and biological meanings of this pain.

RESUMO

Increased, decreased or normal excitability to transcranial magnetic stimulation (TMS) has been reported in the motor (M1) and visual cortices of patients with migraine. Light deprivation (LD) has been reported to modulate M1 excitability in control subjects (CS). Still, effects of LD on M1 excitability compared to exposure to environmental light exposure (EL) had not been previously described in patients with migraine (MP). To further our knowledge about differences between CS and MP, regarding M1 excitability and effects of LD on M1 excitability, we opted for a novel approach by extending measurement conditions. We measured motor thresholds (MTs) to TMS, short-interval intracortical inhibition, and ratios between motor-evoked potential amplitudes and supramaximal M responses in MP and CS on two different days, before and after LD or EL. Motor thresholds significantly increased in MP in LD and EL sessions, and remained stable in CS. There were no significant between-group differences in other measures of TMS. Short-term variation of MTs was greater in MP compared to CS. Fluctuation in excitability over hours or days in MP is an issue that, until now, has been relatively neglected. The results presented here will help to reconcile conflicting observations.

RESUMO

BACKGROUND: New daily persistent headache (NDPH) is a primary chronic daily headache that is generally considered to be difficult to treat. Migraine has been linked to comorbid psychiatric conditions, mainly mood and anxiety disorders, but NDPH has never been linked to psychiatric conditions, and never studied extensively for such an association. CASE: We report nine cases (six women and three men) of patients diagnosed with NDPH and panic disorder who were treated for both conditions. Six of them (66%) had good or excellent responses. CONCLUSION: The spectrum of anxiety disorders, particularly panic disorder, should be considered in NDPH patients. Simultaneous treatment of both disorders may lead to good outcomes.

RESUMO

New daily-persistent headache is a relatively uncommon type of chronic daily headache. The critical features of the original description and the subsequent Silberstein-Lipton description was the onset: daily headache starts abruptly without a background of frequent or worsening headache. In 2004, the International Headache Society classification committee excluded an abundance of migrainous features. The exclusion of patients with too many migrainous features from the International Headache Society classification was contentious from the onset and is a source of consternation for many headache experts. Many contend that the sudden onset of a daily headache raises the same issue of what turned on the headache, irrespective of the headache features. Switch-related questions about predisposing factors or precipitating events are equally valid regardless of how many migrainous features the patient has. The differential diagnosis, treatment response, or prognoses do not vary by the number of migrainous features. The current International Headache Society definition excludes more than half of patients with new onset of daily headache. This exclusion due to migrainous features could have adverse scientific, diagnostic, and treatment consequences.

RESUMO

INTRODUCTION: Cluster headache is characterized by severe attacks of unilateral pain, but many patients experience symptoms more commonly associated with migraine such as persistent pain. PATIENTS AND METHODS: We evaluated cluster headache patients using a questionnaire and chart review to determine clinical characteristics. RESULTS: Twenty-four of 50 subjects reported interictal pain outside of their acute attacks. Sixteen reported persistent pain more than half the time while in cycle. Unlike acute attacks, this pain was generally mild. CONCLUSIONS: Subjects with persistent interictal pain were more likely to have chronic cluster, allodynia, and suboptimal response to sumatriptan, suggesting that interictal pain in cluster headache may predict a more severe disease process.

RESUMO

BACKGROUND: Electronic medical records (EMRs) are used in large healthcare centers to increase efficiency and accuracy of documentation. These databases may be utilized for clinical research or to describe clinical practices such as medication usage. METHODS: We conducted a retrospective analysis of EMR data from a headache clinic to evaluate clinician prescription use and dosing patterns of topiramate. The study cohort comprised 4833 unique de-identified records, which were used to determine topiramate dose and persistence of treatment. RESULTS: Within the cohort, migraine was the most common headache diagnosis (n = 3753, 77.7%), followed by tension-type headache (n = 338, 7.0%) and cluster or trigeminal autonomic cephalalgias (n = 287, 5.9%). Physicians prescribed topiramate more often for subjects with migraine and idiopathic intracranial hypertension (P < .0001) than for those with other conditions, and more often for subjects with coexisting conditions including obesity, bipolar disorder, and depression. The most common maintenance dose of topiramate was 100 mg/day; however, approximately 15% of subjects received either less than 100 mg/day or more than 200 mg/day. More than a third of subjects were prescribed topiramate for more than 1 year, and subjects with a diagnosis of migraine were prescribed topiramate for a longer period of time than those without migraine. CONCLUSIONS: Findings from our study using EMR demonstrate that physicians use topiramate at many different doses and for many off-label indications. This analysis provided important insight into our patient populations and treatment patterns.
