Headache and Visual Aura Outcomes After Stereotactic Radiosurgery for Patients With Occipital Lobe Arteriovenous Malformations: A Single-Center Retrospective Cohort Study.

Patients with brain arteriovenous malformations (BAVMs) sometimes experience migraine-like chronic headaches. Reportedly, this symptom is common in occipital lobe BAVMs; however, the exact prevalence has not been clarified, and the details of visual auras have been scarcely reported. Furthermore, no comprehensive studies exist on the improvement of migraine associated with visual auras in occipital lobe BAVMs after stereotactic radiosurgery (SRS). Therefore, this study investigated the prevalence of headache with visual aura in patients with occipital lobe BAVMs and evaluated the impact of SRS on preexisting symptoms. As a single-center retrospective cohort study, a total of 104 patients with occipital lobe BAVMs treated with SRS from 1990 to 2024 were analyzed. Pre-SRS and post-SRS symptoms of headache and visual aura were documented. The outcomes measured were headache severity, frequency, aura characteristics, and BAVM obliteration rates. Of the 104 patients, 41 (39%) reported chronic headache pre-SRS, and 37 (36%) experienced migraine with visual aura. Compared with pre-SRS, 90% (28/31) of the patients experienced a >50% reduction in headache severity and frequency at a median follow-up of 11 months, and 89% (25/28) experienced a >50% reduction in aura frequency. Complete headache remission was achieved in 35% (13/31) of patients. Complete obliteration of BAVMs was confirmed in 75% (76/102) of the patients at a median of 33 months. A smaller nidus volume was associated with both complete headache remission and BAVM obliteration, whereas age and sex were not significant predictors of headache outcome. Patients with occipital lobe BAVMs frequently experience migraine-like headaches with visual aura, which may be more prevalent than in the general population. SRS for occipital lobe BAVMs could not only achieve favorable BAVM obliteration with minimal adverse effects but also significantly improve migraine-like symptoms, including visual aura, particularly in patients with smaller nidus volumes.

Repetitive transcranial magnetic stimulation in new daily persistent headache patients: a single arm open label study

BackgroundNew daily persistent headache (NDPH) is a continuous, unremitting headache from onset that yields suboptimal results with traditional medicines. Repetitive transcranial magnetic stimulation (rTMS) has emerged as a promising non-invasive treatment for other headache disorders, such as migraine, and neuromodulation has not been well-studied in NDPH. The objective of the study was to evaluate the efficacy of rTMS in reducing the frequency and severity of headaches, and associated anxiety and depressive symptoms in NDPH patients.MethodsThis was an open label prospective, single arm, interventional pilot study conducted between October 2022 and September 2023. All eligible participants received 10 Hz rTMS (600 pulses, 10 trains), delivered to the left prefrontal cortex for three consecutive days. The post-rTMS headache severity was recorded weekly for four weeks and headache free days/functional disability, PHQ-9, and GAD-7 scores at the end of four weeks and compared with pre-rTMS parameters. The primary outcome was defined by ≥ 50% reduction in headache severity on Visual Analogue Scale (VAS) score, decrease in headache days from the baseline and secondary outcome was ≥ 6 point reduction in HIT-6 score at 4 weeks.ResultsFifty NDPH patients (mean [SD] age, 35.06 [13.91] years; 31 females [62%]) participated in this study. Thirty-five patients (70%) reported ≥ 50% improvement in pain severity (p-value < 0.001), with a mean reduction of 10.84 (4.88) headache days per 28 days from a baseline of 28 headache days (p-value < 0.001). Thirty-eight patients (76%) reported a ≥ 6 point’s reduction in HIT score at 4 weeks. Maximum improvement in the above parameters was observed in NDPH patients with chronic migraine. Two patients reported intolerance to the sound of the rTMS. The median (IQR) PHQ-9 and GAD-7 scores reduced from 11.5(3.75,20) to 7(2,15) (p-value < 0.001) and 10(3,14) to 5.5(0,9) (p-value < 0.001) respectively.ConclusionrTMS was well tolerated and effective in reducing pain severity, headache days and headache related disability, depressive and anxiety symptoms.Trial registrationCTRI/2023/05/053247.

D15. Non-pharmacologic Treatments for Chronic and Episodic Migraine: A Systematic Review and Meta-analysis

PURPOSE: Minimally invasive techniques for treatment-resistant migraine have been developed upon recent insights into the peripheral pathogenesis of migraines. Although there is a growing body of evidence supporting these techniques, no study has yet compared the effects of these treatments on headache frequency, severity, duration, and cost. METHODS: PubMed, Embase, and Cochrane Library databases were searched to identify randomized placebo-controlled trials that compared radiofrequency ablation, botulinum toxin-A (BT-A), nerve block, neurostimulation, or migraine surgery to placebo for preventive treatment. Data on changes from baseline to follow-up in headache frequency, severity, duration, and quality of life were analyzed. RESULTS: A total of 30 randomized controlled trials and 2680 patients were included. Compared to placebo, there was a significant decrease in headache frequency in patients with nerve block (p=0.04) and surgery (p<0.001). Headache severity decreased in all treatments. Duration of headaches was significantly reduced in the BT-A (p<0.001) and surgery cohorts (p=0.01). Quality of life improved significantly in patients with BT-A, nerve stimulator, and migraine surgery. Migraine surgery had the longest lasting effects (11.5 months) compared with nerve ablation (6 months), BT-A (3.2 months), and nerve block (11.9 days). CONCLUSION: Migraine surgery is a cost-effective, long-term treatment to reduce headache frequency, severity, and duration without significant risk of complication. BT-A reduces headache severity and duration, but is short lasting and associated with greater adverse events and lifetime cost. Although efficacious, radiofrequency ablation and implanted nerve stimulators have high risks of adverse events and explanation, while benefits of nerve blocks are short in duration.

Effect of Pranayama as Adjuvant to Medical Treatment on Severity, Frequency, and Duration of Headache in Migraine Patients: An Open-Label Randomized Controlled Trial.

Migraine is the second leading cause of disability worldwide with high rates of dissatisfaction for allopathic treatment among patients. Pranayama is an easy, convenient, and cost-effective method that can supplement existing standard medical treatment of migraine. To study the effect of pranayama as an adjuvant to standard medical treatment of migraine on clinical outcome variables of migraine. This was a randomized controlled trial conducted on 80 consecutive migraine patients who were diagnosed as per International Classification of Headache Disorders-3 (ICHD-3) criteria and were randomly allocated into two groups, that is, standard medical treatment (SMT) group and standard medical treatment plus pranayama (SMT + P) group. The effect of pranayama on clinical outcome variables of migraine was evaluated by using standardized questionnaires. The data was statistically analyzed using SPSS Statistics 20 software. A P value of ≤0.05 was considered statistically significant. Intragroup analysis showed all clinical outcome variables of migraine reduced significantly in the SMT + P group whereas all clinical outcome variables of migraine except the duration of headache episodes reduced significantly in the SMT group. Although statistically non-significant, intergroup analysis demonstrates that reduction in headache severity, duration of headache episodes, and headache impact test-6 (HIT-6) score was more in the SMT + P group whereas reduction in headache frequency and migraine disability assessment (MIDAS) score was more in the SMT group. Pranayama supplements the standard medical treatment of migraine by reducing the duration of headache episodes in addition to the reduction in headache severity, headache frequency, HIT-6 scores, and MIDAS scores.

BOTULINUM TOXIN FOR TREATMENT OF MIGRAINE HEADACHES – A STUDY FROM TERTIARY EYE CARE CENTRE

Background - Migraine is one of the common causes of recurrent headaches. Botulinum toxin type A (Botox®) is a neurotoxin produced by Clostridium botulinum that paralyzes nerves. The purpose of this study was to evaluate the efficacy of pericranial Botox® administration in migraine headache in patients attending a tertiary eye care centre. Method - A prospective,non-randomized study consisting of 54 patients was performed.Subjects were candidates who either sought Botox® treatment for hyperfunctional facial lines with concomitant headache or candidates for Botox® treatment specifically for headaches. Headaches were classified based on International Headache Society criteria. Botox® was injected into the glabellar,temporal,frontal,and/or suboccipital regions of the head and neck.Patients were treated every three months,with a maximum of three sessions.Botox dosage ranged from 75 - 155 Units per patient.Main outcome measures were relief from migraine headache symptoms, reduction of headache severity and duration of symptom free period. Results - Age ranged from 18 to 65 (mean 34.6±6.5) years. Among 54 subjects treated prophylactically,complete response (symptom elimination) was noted in 31 (57.40%) with a mean {Standard deviation – (SD)} response duration of 4.3 (2.4) months; 16 (29.62%) reported partial response (≥50% reduction in headache frequency or severity) with a mean (SD) response duration of 2.5 (1.7) months. 7 (12.96%) reported no response. No systemic adverse effects were reported.Conclusion - Botox® is found to be a safe and effective therapy for prophylactic treatment of migraine.

Outcomes of transcutaneous nerve stimulation for migraine headaches: a systematic review and meta-analysis.

Implanted and transcutaneous nerve stimulators have shown promise as novel non-pharmacologic treatment for episodic and chronic migraines. The purpose of this study was to summarize the reported efficacy of transcutaneous single nerve stimulators in management of migraine frequency and severity. A systematic review of five databases identified studies treating migraines with transcutaneous stimulation of a single nerve. Random effects model meta-analyses were conducted to establish the effect of preventive transcutaneous nerve stimulation on headache days per month and 0-10 numeric rating scale pain severity of headaches for both individuals with episodic and chronic migraines. Fourteen studies, which treated 995 patients, met inclusion criteria, including 7 randomized controlled trials and 7 uncontrolled clinical trials. Transcutaneous nerve stimulators reduced headache frequency in episodic migraines (2.81 fewer headache days per month, 95% CI 2.18-3.43, I2 = 21%) and chronic migraines (2.97 fewer headache days per month, 95% CI 1.66-4.28, I2 = 0%). Transcutaneous nerve stimulators reduced headache severity in episodic headaches (2.23 fewer pain scale points, 95% CI 1.64-2.81, I2 = 88%). Preventive use of transcutaneous nerve stimulators provided clinically significant reductions in headache frequency in individuals with chronic or episodic migraines. Individuals with episodic migraines also experienced a reduction in headache pain severity following preventive transcutaneous nerve stimulation.

Outcomes of Surgical Treatment of Migraines: A Systematic Review & Meta-Analysis.

Background: Migraine surgery at 1 of 6 identified "trigger sites" of a target cranial sensory nerve has rapidly grown in popularity since 2000. This study summarizes the effect of migraine surgery on headache severity, headache frequency, and the migraine headache index score which is derived by multiplying migraine severity, frequency, and duration. Materials and Methods: This is a PRISMA-compliant systematic review of 5 databases searched from inception through May 2020 and is registered under the PROSPERO ID: CRD42020197085. Clinical trials treating headaches with surgery were included. Risk of bias was assessed in randomized controlled trials. Meta-analyses were performed on outcomes using a random effects model to determine the pooled mean change from baseline and when possible, to compare treatment to control. Results: 18 studies met criteria including 6 randomized controlled trials, 1 controlled clinical trial, and 11 uncontrolled clinical trials treated 1143 patients with pathologies including migraine, occipital migraine, frontal migraine, occipital nerve triggered headache, frontal headache, occipital neuralgia, and cervicogenic headache. Migraine surgery reduced headache frequency at 1 year postoperative by 13.0 days per month as compared to baseline (I2 = 0%), reduced headache severity at 8 weeks to 5 years postoperative by 4.16 points on a 0 to 10 scale as compared to baseline (I2 = 53%), and reduced migraine headache index at 1 to 5 years postoperative by 83.1 points as compared to baseline (I2 = 2%). These meta-analyses are limited by a small number of studies that could be analyzed, including studies with high risk of bias. Conclusion: Migraine surgery provided a clinically and statistically significant reduction in headache frequency, severity, and migraine headache index scores. Additional studies, including randomized controlled trials with low risk-of-bias should be performed to improve the precision of the outcome improvements.

Case Report on Cerebral Venous Sinus Thrombosis

Introduction: Cerebral venous sinus Thrombosis is the unusual cause of a stroke affecting both reproductively old and genetically or thrombotic risk factors (CVST). The superior sagittal sinus and the cross sinus are two most common places for thrombus formation. A 26-year-old Man was taken to the Acharya Vinoba Bhave Rural Hospital with a new-onset complex-partial convulsion with secondary generalization, headache, and emesis seven days before presentation. Later on he experienced headache which was acute in onset and continuous in nature which was associated with fever. Patient had 1 episode of seizers lasting for 3-4 mints. Which was associated with fall on ground. He complained about weakness in left upper limb.&#x0D; The patient was then transferred to our care institution for definitive management. On arrival, the patient’s neurological examination was done and he reported a severe headache. MRI imaging performed at our institution. The patient was followed clinically, and no posttreatment imaging studies were performed. Following a 3-day hospital stay, the patient reported a significant reduction in headache severity and was discharged home.

A Randomized Controlled Trial of High Rate rTMS Versus rTMS and Amitriptyline in Chronic Migraine

The patients with chronic migraine (CM) respond poorly to pharmacological agents including tricyclic antidepressants, beta-blockers, anticonvulsants, calcium channel blockers, flunarizine, and melatonin. The combination of 2 or more pharmacological agents has not shown better efficacy but increased side effects. High rate repetitive transcranial magnetic stimulation (rTMS) has been reported effective in episodic migraine and converts CM to episodic migraine. A combination of high rate rTMS with a pharmacological agent may be more effective compared to rTMS alone. We evaluate the efficacy and safety of 10 Hz rTMS compared to rTMS and amitriptyline in CM. Randomized controlled trial. Tertiary care teaching institute in India. Patients with CM as per International Classification of Headache Disorder third edition (ICHD-3) beta criteria were included whose age was between 18 years and 55 years. CM was defined if there were 15 headache days per month and at least 8 of these attacks having migraine characteristics for a period of more than 3 months. Patients with major psychiatric, other neurological or systemic disease, and those on migraine prophylaxis were excluded. The demographic details, frequency of headache attacks and headache days per month, migraine triggers, and associated symptoms were noted. The severity of headache was noted using a 0-10 Visual Analog Scale and the number of abortive drugs per month was noted. CM patients were randomly assigned to rTMS (group I) or rTMS and amitriptyline (group II). 10 Hz rTMS was applied using a figure of eight magnetic stimulation coil. The coil was placed over the left frontal cortex corresponding to the hot spot of the right abductor digiti minimi, which is approximately 7 cm lateral from the midline and 2 cm anterior to interaural line. The motor threshold was measured, and 70% of it was used for rTMS. Ten trains of 10 Hz rTMS, each train comprising of 60 pulses with an inter-train interval of 45 seconds were delivered in one session. Three such sessions were delivered on an alternate day and were repeated every month for 3 months. Amitriptyline was prescribed in a dose of 10mg, increased to 25mg after 2 weeks; thereafter increase in dose to 50 mg was optional. The primary outcome was > 50% reduction in headache days, and secondary outcomes were the reduction in severity of headache, abortive drug, and side effects. Forty-one patients were included in group I and 42 in group II, and their baseline characteristics were comparable. A higher proportion of group II patients had more than 50% reduction in headache days at 3 months (76.2 vs 31.7%; P < 0.001) compared to group I. More than 50% reduction in headache severity was also greater in group II compared to group I at 3 months (47.6% vs 19.5%; P = 0.01). Side effects were comparable, and none had to be withdrawn. A higher proportion of patients was shifted from group I to group II. Combination of rTMS and amitriptyline is safe and more effective in CM compared to rTMS alone.

Cannabinoid Use in a Tertiary Headache Clinic: A Cross-Sectional Survey.

This study seeks to determine the prevalence and nature of cannabis use in patients with headache in a tertiary headache clinic and to explore patients' empiric experience in using cannabinoids therapeutically. Many patients with headache report cannabinoid use as an effective abortive and/or preventive therapy. Mounting evidence implicates cannabinoids in pain mechanisms pertaining to migraine and other headache types. A cross-sectional study surveyed 200 patients presenting with any headache disorder to a tertiary headache clinic in Calgary, Alberta. Descriptive analyses were applied to capture information about headache diagnoses and the frequency, doses and methods of cannabinoid delivery employed, as well as patients' perceptions of therapeutic benefit and selected negative side effects. Active cannabinoid users comprised 34.0% of respondents. Approximately 40% of respondents using cannabinoids engaged in very frequent use (≥300 days/year). Of cannabinoid modalities, liquid concentrates were most popular (39.2%), followed by smoked cannabis (33.3%). Patients endorsed cannabinoid use for both prevention and acute therapy of headaches, often concurrently. Sixty percent of respondents felt cannabinoids reduced headache severity, while 29.2% perceived efficacy in aborting headaches. Nearly 5% of respondents volunteered that they had encountered a serious problem such as an argument, fight, accident, or work issue as a result of their cannabis use. Approximately 35.4% of users had attempted to reduce their use. This survey shows that over one-third of patients with headache disorders in a tertiary headache clinic use cannabis as a treatment for their headaches. Of these, about 25% and 60% perceive improvements in headache frequency and severity, respectively. The results of this survey will aid neurologists and headache specialists in understanding the landscape of cannabinoid use in a more severely affected population and inform future-controlled studies of cannabinoids in headache patients.

Overall trend towards headache remission during the COVID-19 pandemic among Chinese patients with pre-existing headache highlights the role of family support

BackgroundThe global status of the COVID-19 pandemic is not optimistic. This is a particularly vulnerable time for patients with pre-existing headache disorders. The present study aimed to investigate the impact of the COVID-19 pandemic on headache patients in China.MethodsA survey was conducted through an online survey platform on June 6, 2020. Demographic characteristics, the PHQ-9, the ISI, a COVID-19 questionnaire and a headache profile survey were included in the online questionnaire.ResultsEventually, a total of 15,000 participants from China completed the online questionnaire. Among them, 2806 participants had pre-existing headache disorders. Our analysis showed reductions in the duration of headaches (3.414 ± 6.859 vs 4.033 ± 7.325 h, P<0.001), number of headache days per month (1.788 ± 2.989 vs 2.092 ± 3.694, P<0.001), and headache intensity (4.110 ± 1.609 vs 4.290 ± 1.680, P<0.001) during the COVID-19 pandemic. Smoking (OR = 1.397, 95% CI 1.090 to 1.790, P = 0.008) and getting support from family members during social isolation (OR = 1.656, 95% CI 1.075 to 2.550, P = 0.022) were independent factors affecting the reduction in the duration of headaches. Education level (OR = 1.478, 95% CI 1.103 to 1.980, P = 0.009) and having a relative or acquaintance who contracted COVID-19 (OR = 0.643, 95% CI 0.458 to 0.902, P = 0.011) were the independent factors affecting the reduction in headache severity. Living in the Wuhan area, having symptoms or a diagnosis of COVID-19 and having relatives or acquaintances who had contracted COVID-19 were associated with the worsening of headaches.ConclusionsParticipants experienced an overall trend towards the improvement of headaches during the COVID-19 pandemic. Family support might play an important role in the improvement of headaches.

Reduction in the severity and duration of headache following fremanezumab treatment in patients with episodic and chronic migraine.

ObjectiveTo evaluate the impact of fremanezumab on the severity and duration of remaining migraine attacks in patients with chronic migraine (CM) or episodic migraine (EM).BackgroundFremanezumab is a fully humanized monoclonal antibody (IgGΔa) that selectively targets calcitonin gene‐related peptide and is efficacious in reducing migraine frequency.MethodsThis exploratory post hoc analysis included data from three randomized, double‐blind, 12‐week, phase 3 studies (HALO CM, HALO EM, and FOCUS). In all three studies, patients with CM or EM were randomized 1:1:1 to receive subcutaneous quarterly fremanezumab (month 1/2/3: 675 mg/placebo/placebo), monthly fremanezumab (month 1/2/3: 675 mg [CM], 225 mg [EM]/225 mg/225 mg), or matched monthly placebo. Changes from baseline were evaluated in the proportion of headache days of at least moderate severity, peak severity of headache days, mean monthly headache hours (of any severity and at least moderate severity), and mean headache hours per headache day of any severity.ResultsA total of 2843 patients were randomized with 2823 patients included in the efficacy analyses across all studies (HALO CM, N = 1121; HALO EM, N = 865; FOCUS, N = 837). At study baseline, mean (standard deviation [SD]) monthly number of headache days rated moderate or severe in the quarterly fremanezumab, monthly fremanezumab, and placebo groups, respectively, were 13.2 (5.5), 12.8 (5.8), and 13.3 (5.8) in HALO CM; 7.2 (3.1), 6.8 (2.9), and 6.9 (3.1) in HALO EM; and 12.4 (5.8), 12.7 (5.8), and 12.8 (5.9) in FOCUS. Patients experienced significant least‐squares mean (LSM; 95% confidence interval) percent reductions from baseline in monthly number of headache days rated moderate or severe during the 12 weeks: HALO CM, quarterly fremanezumab, 34.5% (−39.8, −29.2) and monthly fremanezumab, 36.2% (−41.4, −31.0) vs. placebo, 19.6% (−20.0, −14.3); HALO EM, quarterly fremanezumab, 40.7% (−47.8, −33.5) and monthly fremanezumab, 43.4% (−50.4, −36.3) vs. placebo, 17.9% (−24.9, −11.0); and FOCUS, quarterly fremanezumab, 36.5% (−41.9, −31.1) and monthly fremanezumab, 38.6% (−44.0, −33.3) vs. placebo, 3.5% (−8.9, 1.8); all p < 0.0001. At study baseline, mean (SD) number of monthly headache hours rated moderate or severe in the quarterly fremanezumab, monthly fremanezumab, and placebo groups, respectively, were 66.4 (58.8), 68.0 (53.9), and 68.5 (57.0) in HALO CM; 33.3 (25.4), 31.7 (23.7), and 31.6 (23.2) in HALO EM; and 59.2 (54.7), 64.3 (65.2), and 65.9 (70.2) in FOCUS. Significant reductions were observed in LSM (standard error) number of monthly headache hours of at least moderate severity: HALO CM, quarterly fremanezumab, 24.4 (2.5) and monthly fremanezumab, 26.4 (2.3) vs. placebo, 14.1 (2.5); HALO EM, quarterly fremanezumab, 14.5 (1.4) and monthly fremanezumab, 15.5 (1.3) vs. placebo, 8.1 (1.3); and FOCUS, quarterly fremanezumab, 16.8 (3.0) and monthly fremanezumab, 18.3 (3.0) vs. placebo, 2.3 (3.0); all p < 0.001.ConclusionThese analyses demonstrated that quarterly or monthly treatment with fremanezumab significantly reduced headache severity and duration in patients with CM or EM, including in patients with documented inadequate response to two to four prior migraine preventive medication classes.

Telemedicine in Pediatric Headache: A Review and Practical Implementation

Purpose of ReviewThe purpose of this review was to summarize the current literature about telemedicine in pediatric headache and to provide practical guidance for its implementation.Recent FindingsThere are few studies dedicated to telemedicine in pediatric headache, and existing studies are small. Patients and families report high levels of satisfaction with telemedicine, and most are willing to continue telemedicine visits in the future. Telemedicine demonstrated similar reductions in headache frequency, severity, and duration as patients treated in-person. Remotely delivered psychologic interventions have some utility in reducing headache severity acutely. Families feel telemedicine reduces geographic and financial barriers to care.SummaryTelemedicine in pediatric headache is a growing field. While there is limited research available, it appears safe, efficacious, and feasible. Headache-related outcomes, including frequency, severity, and duration, were similar amongst telemedicine and in-person visits. Future studies should include larger sample sizes and detailed analysis of adverse outcomes.

Comparing propofol with placebo for early resolution of acute migraine in adult emergency department patients: A double-blind randomised controlled trial.

To compare propofol with placebo in adult ED patients with acute migraine. Primary outcome was headache resolution by 1 h. Secondary outcome was reduction in headache severity by two or more points on a numerical rating scale. Double-blind randomised controlled clinical trial comparing propofol (10 mg/mL) with placebo (20% intralipid). Adults with acute migraine without aura were included. The study drug was administered as an initial dose of 4 mL followed by up to five doses of 2 mL, delivered 5 min apart. Pain scores were taken prior to each dose and further administration was ceased when either the pain score was zero or the maximum dosage reached (140 mg of propofol or 14 mL of 20% intralipid). Of 40 recruited patients, 21 received propofol and 19 placebo. Headache resolution occurred for 5 (24%, 95% CI 13-57) and 6 (32%, 95% CI 13-57) patients, respectively, difference 8% (95% CI -20 to 36). Headache severity reduction by two or more numerical rating scale points was reported by 17 (81%, 95% CI 58-95) and 7 (37%, 95% CI 16-62) patients, respectively, difference 44% (95% CI 17-71). Propofol was not superior to placebo for the primary outcome of early headache resolution. Superiority of propofol for the secondary outcome of headache severity reduction suggests that further research may be warranted.

Zinc supplementation affects favorably the frequency of migraine attacks: a double-blind randomized placebo-controlled clinical trial

BackgroundObservational studies have shown a link between zinc deficiency and migraine headaches. We aimed to examine the effect of zinc supplementation on the characteristics of migraine attacks in patients with migraine.MethodsThis randomized clinical trial was conducted on 80 patients with migraine. Patients were randomly assigned to receive either zinc sulfate (220 mg/d zinc sulfate) or placebo (lactose) for 8 weeks. Anthropometric measures, serum zinc concentrations, and characteristics of migraine attacks (headache severity, frequency and duration of migraine attacks, and headache daily results) were assessed at baseline and end of the trial.ResultsCompared with the placebo, zinc supplementation resulted in a significant reduction in headache severity (− 1.75 ± 1.79 vs. -0.80 ± 1.57; P = 0.01) and migraine attacks frequency (− 2.55 ± 4.32 vs. -0.42 ± 4.24; P = 0.02) in migraine patients. However, the observed reduction for headache severity became statistically non-significant when the analysis was adjusted for potential confounders and baseline values of headache severity. Other characteristics of migraine attacks including the duration of attacks and headache daily results were not altered following zinc supplementation either before or after controlling for covariates.ConclusionZinc supplementation had a beneficial effect on the frequency of migraine attacks in migraine patients. Additional well-designed clinical trials with a long period of intervention and different dosages of zinc are required.Trial registration codeIRCT20121216011763N23 at www.irct.ir.

Suppression of Menstrual-Related Migraine Attack Severity Using Pyridoxine, Thiamine, and Cyanocobalamin: A Quasi-Experimental Within-Subject Design

Background: B-group vitamins can potentially contribute to migraine prophylaxis through various mechanisms. We conducted a quasi-experimental study to assess the efficacy and tolerability of a combination of vitamins B1, B6, and B12 (Neurobion) for prophylaxis of menstruation-related migraine attacks. Methods: Women diagnosed with menstrual-related migraine, both chronic and episodic headaches, were enrolled. The patients began Neurobion therapy one week before the menstruation cycle, and repeated the injection for three consecutive months; each ampoule contained 100 mg of vitamins B1 and B6 as well as 1000 μg of vitamin B12. Neurobion was used as an add-on therapy for patients receiving the same prophylactic therapy during the last two months before the start of the study. The outcome parameter examined the severity of menstrual-related migraine attacks on a 10-point visual analog scale (VAS). Results: Three hundred eighty-three patients (169 with chronic migraine and 214 with episodic migraine) were included in the final analysis. The patients received treatment with a combination of vitamins B1, B6, and B12 with positive results. The mean intensity of menstrual-related migraine attacks was reduced from 6.7 on the 10-point VAS to 3.2 (P &lt; 0.001) in patients with chronic migraine. The mean severity of menstrual-related migraine attacks was also reduced from 7.2 to 3.7 in patients with episodic migraine (P &lt; 0.001). There was no significant difference in the reduction of headache severity between the two groups of migraineurs (P = 0.985). Conclusions: Neurotropic vitamins, including pyridoxine, thiamine, and cyanocobalamin yielded significant reductions in the severity of menstrual-related migraine attacks. Neurobion as a combination of vitamins B1, B6, and B12 appears to be well-tolerated and beneficial as an adjuvant in treatment and prophylaxis of menstrual-related migraine attacks. Further large-scale trials with long-term follow-up will be required to confirm our results.

Prospective Double-Blinded Randomized Field-Based Clinical Trial of Metoclopramide and Ibuprofen for the Treatment of High Altitude Headache and Acute Mountain Sickness

High altitude headache (HAH) and acute mountain sickness (AMS) are common pathologies at high altitudes. There are similarities between AMS and migraine headaches, with nausea being a common symptom. Several studies have shown ibuprofen can be effective for AMS prophylaxis, but few have addressed treatment. Metoclopramide is commonly administered for migraine headaches but has not been evaluated for HAH or AMS. We aimed to evaluate metoclopramide and ibuprofen for treatment of HAH and AMS. We performed a prospective, double-blinded, randomized, field-based clinical trial of metoclopramide and ibuprofen for the treatment of HAH and AMS in 47 adult subjects in the Mount Everest region of Nepal. Subjects received either 400 mg ibuprofen or 10 mg metoclopramide in a 1-time dose. Lake Louise Score (LLS) and visual analog scale of symptoms were measured before and at 30, 60, and 120 min after treatment. Subjects in both the metoclopramide and ibuprofen arms reported reduced headache severity and nausea compared to pretreatment values at 120 min. The ibuprofen group reported 22 mm reduction in headache and 6 mm reduction in nausea on a 100 mm visual analog scale at 120 min. The metoclopramide group reported 23 mm reduction in headache and 14 mm reduction in nausea. The ibuprofen group reported an average 3.5-point decrease on LLS, whereas the metoclopramide group reported an average 2.0-point decrease on LLS at 120 min. Metoclopramide and ibuprofen may be effective alternative treatment options in HAH and AMS, especially for those patients who additionally report nausea.

Headache Outcomes After Treatment of Unruptured Intracranial Aneurysm: A Systematic Review and Meta-Analysis.

Background and Purpose- While unruptured intracranial aneurysms may be discovered incidentally in the workup of chronic headache, it remains unclear whether their treatment ultimately impacts headache severity. We aim to conduct a systematic review and meta-analysis assessing headache severity after treatment of unruptured intracranial aneurysm. Methods- MEDLINE and EMBASE were systematically reviewed. Results- Data from 7 studies met inclusion criteria (309 nonduplicated patients). The standard mean difference in pre- and post-intervention headache severity was estimated at -0.448 (95% CI, -0.566 to -0.329) under a random effects model. No significant heterogeneity was noted nor was any significant publication bias demonstrated. Conclusions- This is the first systematic review assessing postoperative headache severity following treatment of unruptured intracranial aneurysm. While a significant reduction in headache severity was observed, further investigation into this phenomenon is recommended before it influences clinical practice. Future study should stratify headache outcomes by aneurysm size, location, and treatment modality.
