Plain language summary
Migraine is considered as an intense unilateral throbbing headache, often accompanied by nausea, vomiting, photophobia and phonophobia, which can be exacerbated by routine physical activity. It has been shown that cytokines levels are altered in migraineurs. Cytokines are inflammatory mediators that can stimulate calcitonin gene-related peptide (CGRP) [amino acid] transcription. The aim of this study was to investigate the effects of soy isoflavones supplementation on migraine headache characteristics, mental status, quality of life and CGRP concentration in adult women with migraine. This study is a double-blind, placebo-controlled clinic trial. Participants (n=88 women) were randomly assigned to one of the two groups: intervention or placebo groups (1:1). Patients in the intervention group received one tablet containing 50 mg isoflavones. Results indicate that consumption of 50 mg/day soy isoflavones supplementation for 8 weeks led to significant reduction in frequency, duration, and clinical indices of migraine and improved quality of life and CGRP levels. However, severity of migraine headache and mental status including depression, stress and anxiety were not affected by supplementation. Authors conclude that even though their findings were promising, further studies focusing on the mental status dimensions including depression, stress and anxiety are needed.
Abstract
BACKGROUND Literature suggests a relationship between estrogen levels and migraine headache pathogenesis. However, the effect of soy isoflavones on migraine characteristic remains unclear. This study aimed to investigate the effect of soy isoflavones on migraine characteristics and calcitonin gene-related peptide (CGRP) levels in women with migraine. METHODS Eighty-three participants completed a randomized double-blind controlled trial, receiving 50 mg per day soy isoflavones or placebo supplementation for 8 weeks. Migraine severity, migraine days per month, frequency and duration of attacks, mental status, quality of life and serum CGRP levels were measured at baseline and the end of the intervention. Bivariate comparison and intention-to-treat (ITT) were used for analysis. RESULTS Soy isoflavones intake resulted in a significant decrease in mean frequency (-2.36 vs -0.43, P < 0.001), duration (-2.50 vs -0.02, P < 0.001) of migraine attacks and CGRP level (-12.18 ng/l vs -8.62, P = 0.002) in compared to placebo group. Also, a significant improvement was found in quality of life (16.76 vs 2.52, P < 0.001). Although, reduction in the migraine severity and mental status did not reach a statistically significant level (P > 0.05). CONCLUSION soy isoflavones supplementation may be considered as a complementary treatment for women with migraine to improve migraine characteristics and reduce the burden of disease.

Plain language summary
Migraine is a disabling disorder characterized by recurrent attacks affecting the patient’s quality of life. Clinical studies show obesity is an important risk factor for the progression of migraine attacks which is mainly related to inflammatory mediators and adipokines. The aim of this study was to investigate the effects of nano-curcumin supplementation on adipokines levels in obese and overweight patients with migraine. This study is a double-blind randomized clinical trial study. Forty-four episodic migraine patients (42 females and 2 males) were enrolled and underwent 2-months nanocurcumin or placebo supplementation. Results show that nano-curcumin significantly reduced MCP-1 levels, attack frequencies, pain severity, and duration of headaches. Authors conclude that targeting curcumin can be a promising approach to migraine management. However further research is needed to determine the gene expression and western blot of the examined adipokines.
Abstract
OBJECTIVE The present study aimed to investigate the effects of nano-curcumin supplementation on adipokines levels and clinical signs in obese and overweight patients with migraine. RESULTS Forty-four patients with episodic migraine participated in this clinical trial and were divided into two groups nano-curcumin (80 mg/day) and the control group over 2-month period. At the baseline and the end of the research, the serum levels of MCP-1, Resistin, and Visfatin were measured using the ELISA method. In addition, the headache attack frequencies, severity, and duration of pain were recorded. The results of the present study showed that nano-curcumin can significantly reduce MCP-1 serum levels in the nano-curcumin supplemented group (P = 0.015, size effect = 13.4%). In the case of resistin and visfatin, nano-curcumin supplementation exerted no statistically significant changes in serum levels (P > 0.05). Nano-curcumin also significantly reduced the attack frequencies, severity, and duration of headaches (P < 0.05). These findings indicate that targeting curcumin can be a promising approach to migraine management. However, further comprehensive human trials are needed to confirm these findings.

Patients with migraine may experience neck pain, worsened performance of cervical muscles, reduced cervical spine range of motion, and increased muscle sensitivity in the craniocervical region. Physiotherapy is an important nonpharmacological treatment option for reducing the duration and frequency of migraine attacks and may include manual therapy, soft-tissue techniques, and strength and endurance training. The aim of this study was to verify the effectiveness of craniocervical muscle-strengthening exercise (CMSE) in reducing the frequency and intensity of headache in migraine patients. This study is a two-armed, parallel-group randomized controlled trial. Men and women aged between 18 and 55 years, diagnosed only with migraine and at least three days of pain per month were included. Participants were randomly assigned to one of the two groups; intervention (n=21) or placebo (n=21) group. Results show that CMSE neither reduced the frequency and intensity of headache nor improved the performance and sensitivity of the cervical muscles, cervical range of motion, and migraine and neck pain-related disabilities. However, a significant improvement for pressure pain threshold was noticed in the sensitivity of the frontal muscle in favour of the intervention group. Authors conclude that performing CMSE is not enough to reduce the frequency and intensity of headache or improve the performance of the cervical muscles and reduce migraine and neck pain related disabilities.
Abstract
BACKGROUND Migraine patients have musculoskeletal disorders and pain in the cervical. And, despite the pathophysiology demonstrating the relationship between migraine and the cervical spine, the effectiveness of craniocervical exercises in these patients has not been verified. So, the aimed of this study was verify the effectiveness of craniocervical muscle-strengthening exercise (CMSE) in reducing the frequency and intensity of headache in migraine patients. METHODS A two-armed, parallel-group randomized controlled trial with a 3-month follow-up was performed. For eight weeks, the volunteers in the intervention group (n = 21) performed a protocol of CMSE, while those in the sham ultrasound group (n = 21) received the application of disconnected therapeutic ultrasound in the upper trapezius and guideline for home-stretching. The primary outcomes were the frequency and intensity of the headache. The secondary outcomes were questionnaires about migraine and neck disability, and satisfaction with the treatment, cervical range of motion, the pressure pain threshold, craniocervical flexion test (CCFT), cervical muscle strength and endurance test, and the cervical muscle activity during the physical tests. RESULTS No differences were observed for the changes observed in primary outcomes after eight weeks and at the 3-months follow up (p > 0.05). For the secondary outcomes, craniocervical exercises improved the sensitivity of the frontal muscle (p = 0.040) and promoted a reduced amplitude of muscle activity of the anterior scalene and upper trapezius in the last stages of CCFT (p ≤ 0.010). There was also reduced muscle activity of the anterior scalene and splenius capitis in the endurance test (p ≤ 0.045), as evaluated by surface electromyography. CONCLUSION CMSE were insufficient in reducing the frequency and intensity of headache, improving the performance of the cervical muscles, or reducing migraine and neck pain-related disabilities. This was found despite a decreased electromyographic activity of the cervical muscles during the last stages of CCFT and increased median frequency during the endurance test.

Plain language summary
Mindfulness-based stress reduction (MBSR), a standardized mind-body treatment that teaches momentary awareness with decreased sensory percept judgment, is associated with improvements in many chronic pain conditions. Mindfulness may be particularly helpful for migraine, as it diminishes affective responses to stress, the most common migraine trigger. This study is a double-blinded, randomized clinical trial of MBSR vs headache education for adults with migraine. The study enrolled 96 participants out of which 89 participants attended at least 1 class and completed at least 1 headache log (MBSR, 45; headache education, 44) across 7 cohorts. Participants were randomly assigned to one of the two arms. Results indicate that participants in both groups demonstrated a reduction of migraine days per month from baseline at 12 weeks. Furthermore, both groups sustained reductions in frequency of migraine and headache without group differences. Compared with headache education, MBSR participants had improvements in headache-related disability, quality of life, depression scores, self-efficacy, pain catastrophizing, and decreased experimentally induced pain intensity and unpleasantness out to 36 weeks. Authors conclude that mindfulness may help treat the total burden of migraine. However, a larger, more definitive study is needed to understand the impact of mindfulness on migraine.
Abstract
Importance: Migraine is the second leading cause of disability worldwide. Most patients with migraine discontinue medications due to inefficacy or adverse effects. Mindfulness-based stress reduction (MBSR) may provide benefit. Objective: To determine if MBSR improves migraine outcomes and affective/cognitive processes compared with headache education. Design, Setting, and Participants: This randomized clinical trial of MBSR vs headache education included 89 adults who experienced between 4 and 20 migraine days per month. There was blinding of participants (to active vs comparator group assignments) and principal investigators/data analysts (to group assignment). Interventions: Participants underwent MBSR (standardized training in mindfulness/yoga) or headache education (migraine information) delivered in groups that met for 2 hours each week for 8 weeks. Main Outcomes and Measures: The primary outcome was change in migraine day frequency (baseline to 12 weeks). Secondary outcomes were changes in disability, quality of life, self-efficacy, pain catastrophizing, depression scores, and experimentally induced pain intensity and unpleasantness (baseline to 12, 24, and 36 weeks). Results: Most participants were female (n = 82, 92%), with a mean (SD) age of 43.9 (13.0) years, and had a mean (SD) of 7.3 (2.7) migraine days per month and high disability (Headache Impact Test-6: 63.5 [5.7]), attended class (median attendance, 7 of 8 classes), and followed up through 36 weeks (33 of 45 [73%] of the MBSR group and 32 of 44 [73%] of the headache education group). Participants in both groups had fewer migraine days at 12 weeks (MBSR: -1.6 migraine days per month; 95% CI, -0.7 to -2.5; headache education: -2.0 migraine days per month; 95% CI, -1.1 to -2.9), without group differences (P = .50). Compared with those who participated in headache education, those who participated in MBSR had improvements from baseline at all follow-up time points (reported in terms of point estimates of effect differences between groups) on measures of disability (5.92; 95% CI, 2.8-9.0; P < .001), quality of life (5.1; 95% CI, 1.2-8.9; P = .01), self-efficacy (8.2; 95% CI, 0.3-16.1; P = .04), pain catastrophizing (5.8; 95% CI, 2.9-8.8; P < .001), depression scores (1.6; 95% CI, 0.4-2.7; P = .008), and decreased experimentally induced pain intensity and unpleasantness (MBSR group: 36.3% [95% CI, 12.3% to 60.3%] decrease in intensity and 30.4% [95% CI, 9.9% to 49.4%] decrease in unpleasantness; headache education group: 13.5% [95% CI, -9.9% to 36.8%] increase in intensity and an 11.2% [95% CI, -8.9% to 31.2%] increase in unpleasantness; P = .004 for intensity and .005 for unpleasantness, at 36 weeks). One reported adverse event was deemed unrelated to study protocol. Conclusions and Relevance: Mindfulness-based stress reduction did not improve migraine frequency more than headache education, as both groups had similar decreases; however, MBSR improved disability, quality of life, self-efficacy, pain catastrophizing, and depression out to 36 weeks, with decreased experimentally induced pain suggesting a potential shift in pain appraisal. In conclusion, MBSR may help treat total migraine burden, but a larger, more definitive study is needed to further investigate these results.

Plain language summary
Chronic migraine (CM) is a highly disabling condition in both adults and adolescents. Behavioural approaches are considered helpful for younger patients with high frequency episodic migraine (HFEM) and CM to manage pain, to reduce the number of analgesics and to reduce the use of preventive medications. The main aim of this study was to examine the effect of a mindfulness-based intervention in adolescents with CM or HFEM. Secondary aims include the evaluation of mindfulness effects on medication intake, disability, anxiety, depression, catastrophizing, and caregivers’ burden. This study is a single-arm open-label study which enrolled 37 adolescents aged 12–18 years. After enrolment, patients were followed up for 12 months, with visits at 6 and 12 months (in which patients filled-in the whole protocol), and a phone contact at 3 months. Results indicate that participants who attended the mindfulness-based meditation program and were not prescribed any pharmacological prophylaxis, underwent an improvement of both headache frequency and medication intake at both 6- and 12-months follow-up. They also improved in catastrophizing, symptoms of depression, trait anxiety and disability. Authors conclude that group-based mindfulness intervention merits attention for the management of adolescents with CM and HFEM without aura.
Abstract
In this single-arm pilot open-label study we examined the effect of a mindfulness-based intervention on reduction of headache frequency after 12 months in adolescents aged 12-18 with chronic or high-frequency migraine without aura. Adolescents were recruited at the headache center of the C. Besta Neurological Institute and followed-up for 12 months. The mindfulness-based intervention was delivered in small groups and consisted of six weekly group sessions of guided meditation, and one booster session 15 days after. Patients filled in questionnaires assessing headache frequency (primary endpoint), medication intake, disability, anxiety, depression, catastrophizing, and caregivers' burden. Within-person ANOVA was used to address variation of endpoints over time. Thirty-five out of 37 patients completed the study for primary endpoints, and 33 for secondary endpoints. Headache frequency dropped from 21.3 (95% CI 18.5; 24.1) to 9.6 (95% CI 6.1; 13.1) days per month at 12 months (F = 30.5, p < 0.001); 23 patients out of 35 (65.7%) achieved a headache frequency reduction greater than or equal to 50%. Significant improvements were also reported for medication intake (F = 18.7, p < 0.001), disability (F = 3.8, p = 0.027), trait anxiety (F = 5.1, p = 0.009), symptoms of depression (F = 9.5, p < 0.001), and catastrophizing (F = 23.6, p < 0.001). In conclusions, our study shows a reduction of headache attacks in adolescents who follow a mindfulness-based program, suggesting benefit of this nonpharmacological approach.

Plain language summary
Migraine is a disabling primary headache disorder with 2 major subtypes: migraine without aura and migraine with aura. Certain foods, such as chocolate, caffeine, milk, cheese and alcoholic beverages, have been identified as common triggers of migraine attacks. The aim of this study was to qualitatively summarize data from randomized controlled trials or observational studies on the role of diet patterns, diet-related triggers, and dietary interventions in adults with migraine. This study is a systematic review of forty-three articles. Of the studies included in the review, 11 outlined the evidence on diet patterns, 20 outlined the evidence on diet-related triggers, and 12 outlined evidence on diet as interventions in people with migraine. Results show that evidence regarding the effect of general diet patterns in people with migraine varied in the studies identified. Furthermore, limited high-quality evidence was found. Authors conclude that certain dietary interventions may help to improve clinical outcomes in some people with migraine, but these findings still need to be supported with robust evidence before being recommended for use in clinical practice.
Abstract
BACKGROUND Migraine is a disabling primary headache disorder often associated with triggers. Diet-related triggers are a common cause of migraine and certain diets have been reported to decrease the frequency of migraine attacks if dietary triggers or patterns are adjusted. OBJECTIVE The systematic literature review was conducted to qualitatively summarize evidence from the published literature regarding the role of diet patterns, diet-related triggers, and diet interventions in people with migraine. METHODS A literature search was carried out on diet patterns, diet-related triggers, and diet interventions used to treat and/or prevent migraine attacks, using an a priori protocol. MEDLINE and EMBASE databases were searched to identify studies assessing the effect of diet, food, and nutrition in people with migraine aged ≥18 years. Only primary literature sources (randomized controlled trials or observational studies) were included and searches were conducted from January 2000 to March 2019. The NICE checklist was used to assess the quality of the included studies of randomized controlled trials and the Downs and Black checklist was used for the assessment of observational studies. RESULTS A total of 43 studies were included in this review, of which 11 assessed diet patterns, 12 assessed diet interventions, and 20 assessed diet-related triggers. The overall quality of evidence was low, as most of the (68%) studies assessing diet patterns and diet-related triggers were cross-sectional studies or patient surveys. The studies regarding diet interventions assessed a variety of diets, such as ketogenic diet, elimination diets, and low-fat diets. Alcohol and caffeine uses were the most common diet patterns and diet-related triggers associated with increased frequency of migraine attacks. Most of the diet interventions, such as low-fat and elimination diets, were related to a decrease in the frequency of migraine attacks. CONCLUSIONS There is limited high-quality randomized controlled trial data on diet patterns or diet-related triggers. A few small randomized controlled trials have assessed diet interventions in preventing migraine attacks without strong results. Although many patients already reported avoiding personal diet-related triggers in their migraine management, high-quality research is needed to confirm the effect of diet in people with migraine.

Plain language summary
Migraine is a chronic neurovascular disorder. Patients with this disorder suffer from severe headaches and also nausea, vomiting, photophobia, and phonophobia during a migraine attack. Several supplementary treatments have been suggested for the management of migraine symptoms. Among these methods, there is the supplementation with micronutrients. The aim of this study was to examine the effect of zinc supplementation on characteristics of migraine attacks in migraine patients. This study is a double-blind randomized clinical trial which included migraine patients, with an age range between 20 and 60 years. Patients were stratified based on age (20–40 and 40–60 years), gender (male and female), and body mass index (18.5–24.9 and 25–30) into different blocks. Then, they were randomly allocated to the intervention or control groups. Results show that when compared to the placebo group, zinc supplementation resulted in a significant reduction in headache severity and migraine attacks frequency. However, the effect on headache severity became statistically non-significant when baseline values of headache severity and potential confounders were taken into account. Authors conclude that zinc supplementation was beneficial for migraine attack frequency but not for migraine attack duration and headache daily results.

Summary Review:
Migraines, characterised by severe headaches, nausea, vomiting, photophobia, and phonophobia affect approximately 10-20% of the global population. The authors refer to observational studies that have identified a moderate rate of zinc deficiency amongst migraine sufferers.
Zinc, an essential trace mineral, may prove beneficial as a supplement to reduce migraine symptoms and frequency possibly due to its effects on the nervous system and its antioxidant and anti-inflammatory capacity..
This double blind randomised clinical trial analysed the effects of 220mg of zinc sulphate (50mg of elemental zinc) combined with a routine migraine treatment versus a control group receiving a placebo and the routine treatment on symptoms of migraine attacks. The study duration was 8 weeks occurring from January 2016 to April 2016. Each group consisted of 40 participants between the ages of 20 and 60 with >5 years of migraines or migraine symptoms.
When compared to the placebo group, zinc supplementation demonstrated:
- A reduction in headache severity (− 1.75 ± 1.79 vs. -0.80 ± 1.57; P = 0.01). This result became statistically non-significant when the analysis was adjusted for potential confounders and baseline values of headache severity.
- A reduction in migraine attacks frequency (− 2.55 ± 4.32 vs. -0.42 ± 4.24; P = 0.02).
Clinical practice applications:
This randomised controlled trial highlights that zinc supplementation combined with routine migraine treatment (200/500 mg sodium valproate (such as Depakin), 50/100 mg sumatriptan, or 1 mg ergotamine) may assist in the reduction of migraine attack frequency amongst migraine sufferers within 8 weeks.
Compliance rate for this study was very high at 100% and there were no adverse effects reported suggesting a potentially safe and convenient treatment for migraine sufferers.
Considerations for future research:
- Further trials with better dietary controls would be useful to eliminate potential confounders.
- Use of CONSORT guidelines for reporting randomised trials would strengthen research reporting.
- Analysis of biomarkers may assist in identifying the mechanisms in which zinc may relieve migraine symptoms..
- Larger randomised controlled trials with increased sample sizes and longer durations are needed in order to definitively determine the effect of zinc supplementation on migraine attacks and any differences between genders.
- Additional studies trialling various zinc dosages and forms may provide insight into an optimal zinc dose and form for migraine attacks.
Abstract
BACKGROUND Observational 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. METHODS This 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. RESULTS Compared 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. CONCLUSION Zinc 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 CODE IRCT20121216011763N23 at www.irct.ir .

Plain language summary
The ketogenic diet (KD) constitutes high-fat, adequate protein, and low-carbohydrate, and has been proven to be efficacious for the treatment of drug-resistant epilepsy. Recently, KD showed promising results for treating other neurological conditions. The aim of this study was to analyse the effects of very low-calorie ketogenic diets (VLCKDs) in overweight episodic migraine patients during a weight-loss intervention. This study is a double-blind cross-over design randomised trial (of five phases). Participants eligible for trial participation were overweight/obese adults, aged 18 to 65 years, who had at least 12 months’ history of migraines with or without aura. Subjects alternated randomly between a very low-calorie ketogenic diet and a very low-calorie non-ketogenic diet (VLCnKD) each for one month. Results indicate that a 4-week period VLCKD, despite inducing similar weight loss and glycaemic profile, was significantly more effective than VLCnKD in preventing migraine attacks, as evidenced by a decrease in the frequency of migraine days and attacks, and a greater than 50% response rate. Authors conclude that VLCKD is effective for rapid, short-term improvement of migraines in overweight patients, while VLCnKD is not.
Abstract
Here we aimed at determining the therapeutic effect of a very low-calorie diet in overweight episodic migraine patients during a weight-loss intervention in which subjects alternated randomly between a very low-calorie ketogenic diet (VLCKD) and a very low-calorie non-ketogenic diet (VLCnKD) each for one month. In a nutritional program, 35 overweight obese migraine sufferers were allocated blindly to 1-month successive VLCKD or VLCnKD in random order (VLCKD-VLCnKD or VLCnKD-VLCD). The primary outcome measure was the reduction of migraine days each month compared to a 1-month pre-diet baseline. Secondary outcome measures were 50% responder rate for migraine days, reduction of monthly migraine attacks, abortive drug intake and body mass index (BMI) change. Only data from the intention-to-treat cohort (n = 35) will be presented. Patients who dropped out (n = 6) were considered as treatment failures. Regarding the primary outcome, during the VLCKD patients experienced -3.73 (95% CI: -5.31, -2.15) migraine days respect to VLCnKD (p < 0.0001). The 50% responder rate for migraine days was 74.28% (26/35 patients) during the VLCKD period, but only 8.57% (3/35 patients) during VLCnKD. Migraine attacks decreased by -3.02 (95% CI: -4.15, -1.88) during VLCKD respect to VLCnKD (p < 0.00001). There were no differences in the change of acute anti-migraine drug consumption (p = 0.112) and BMI (p = 0.354) between the 2 diets. A VLCKD has a preventive effect in overweight episodic migraine patients that appears within 1 month, suggesting that ketogenesis may be a useful therapeutic strategy for migraines.

In the age group 15–49 years, migraine is the top cause of years lived with disability, magnifying its impact on the working population. The aim of this study was to summarise the literature published after 2004 on the effect of aerobic exercise in patients with migraine on the number of migraine days, attack duration and pain intensity. This study is a systematic review and meta-analysis of six studies. Result indicate that aerobic exercise can reduce pain intensity (20–54%) in patients with migraine (moderate quality evidence). Furthermore, low quality evidence indicates that aerobic exercise can decrease pain intensity or duration of migraine attacks. Authors conclude that there is moderate evidence that aerobic exercise decreases the number of migraine days.
Abstract
BACKGROUND In patients with frequent migraine, prophylactic treatments are used. Patients often request non-pharmacological alternatives. One treatment option can be aerobic exercise. The value of aerobic exercise as prophylactic treatment however needs to be determined. METHODS A systematic review and meta-analysis was performed to investigate the result of aerobic exercise on the number of migraine days, duration and pain intensity in patients with migraine. After screening three online databases, PubMed, Cochrane library and Web of Science, using predefined in- and exclusion criteria, six studies were retained. Pooling of data was performed when possible. RESULTS Significant reductions in the number of migraine days after aerobic exercise treatment were found with a mean reduction of 0.6 ± 0.3 migraine days/month. Other outcomes were too variable to pool due to heterogeneity of outcome measurements. Unpooled data revealed small to moderate reductions in attack duration (20-27%) and pain intensity (20-54%) after aerobic exercise intervention. Various exercise intensities are applied. CONCLUSION There is moderate quality evidence that in patients with migraine aerobic exercise therapy can decrease the number of migraine days. No conclusion for pain intensity or duration of attacks can be drawn. Effect sizes are small due to a lack of uniformity. For future studies, we recommend standardized outcome measures and sufficiently intense training programs. TRIAL REGISTRATION CRD42018091178 .

Plain language summary
Migraine is a neurological disease characterized by moderate-to-severe headache and accompanying autonomic, affective, and sensory features. It is also comorbid with several diseases, including obesity. The aim of this study was to assess the impact of a standardized behavioural weight loss (BWL) intervention on migraine headache frequency. This study is a parallel-group, single-blinded randomised controlled trail. The participants were randomized to one of the two groups: BWL or migraine education (ME). Results show that changes in migraine headache frequency at post-treatment and follow-up were not significantly different between the BWL and ME control interventions. In fact, both BWL and ME had significant reductions in monthly migraine headache days from baseline to post-treatment and follow-up. Authors conclude that further research is required to better understand treatment mechanisms and whether BWL can enhance effects of standard pharmacologic and/or non-pharmacologic migraine therapies in patients with comorbid overweight/obesity.
Abstract
OBJECTIVE The objective of this study was to test whether behavioral weight loss (BWL) intervention decreases headaches in women with comorbid migraine and overweight or obesity. METHODS This randomized, single-blind trial allocated women 18 to 50 years old with 4 to 20 migraine days per month and a BMI = 25.0-49.9 kg/m2 to 16 weeks of BWL (n = 54), which targeted exercise and eating behaviors for weight loss, or to migraine education control (ME, n = 56), which delivered didactic instruction on migraine and treatments. Participants completed a 4-week smartphone headache diary at baseline, posttreatment (16-20 wk), and follow-up (32-36 wk). The primary outcome was posttreatment change in migraine days per month, analyzed via linear mixed effects models. RESULTS Of 110 participants randomly assigned, 85 (78%) and 80 (73%) completed posttreatment and follow-up. Although the BWL group achieved greater weight loss (mean [95% CI] in kilograms) than the ME group at posttreatment (-3.8 [-2.5 to -5.0] vs. + 0.9 [-0.4 to 2.2], P < 0.001) and follow-up (-3.2 [-2.0 to -4.5] vs. + 1.1 [-0.2 to 2.4], P < 0.001), there were no significant group (BWL vs. ME) differences (mean [95% CI]) in migraine days per month at posttreatment (-3.0 [-2.0 to -4.0] vs. -4.0 [-2.9 to -5.0], P = 0.185) or follow-up (-3.8 [-2.7 to -4.8] vs. -4.4 [-3.4 to -5.5], P = 0.378). CONCLUSIONS Contrary to hypotheses, BWL and ME yielded similar, sustained reductions in migraine headaches. Future research should evaluate whether adding BWL to standard pharmacological and/or nonpharmacological migraine treatment approaches yields greater benefits.
