Comparison of the effects of dietary factors in the management and prophylaxis of migraine

Dietary Patterns and Migraine: Insights and Impact

Migraine is a prevalent neurological disorder characterized by significant disability and triggered by various factors, including dietary habits. This review explores the complex relationship between diet and migraine, highlighting both triggering and protective roles of dietary patterns and specific nutrients. Evidence suggests that certain foods, such as alcohol, caffeine, chocolate, MSG, nitrates, and tyramine, can trigger migraines in susceptible individuals. Conversely, dietary interventions, including carbohydrate-restricted diets, ketogenic diets, vitamin D3 supplementation, omega-3 fatty acids, Mediterranean dietary patterns, and increased water intake, have shown potential in reducing migraine frequency and severity. Observational studies also indicate that maintaining a healthy diet, rich in fruits and vegetables and low in processed foods, is associated with better migraine outcomes. The effectiveness of these interventions varies among individuals, underscoring the importance of personalized approaches. Future studies should further explore the role of diet in migraine management, focusing on randomized trials to establish causality and refine dietary recommendations for patients.

2023 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline for the Management of Headache

DESCRIPTION

Headache medicine and therapeutics evidence have been rapidly expanding and evolving since the 2020 U.S. Department of Veterans Affairs (VA) and U.S. Department of Defense (DoD) clinical practice guideline (CPG) for the management of headache. Therefore, the CPG was revised in 2023, earlier than the standard 5-year cycle. This article reviews the 2023 CPG recommendations relevant to primary care clinicians for treatment and prevention of migraine and tension-type headache (TTH).

METHODS

Subject experts from the VA and the DoD developed 12 key questions, which guided a systematic search using predefined inclusion and exclusion criteria. After reviewing evidence from 5 databases published between 6 March 2019 and 16 August 2022, the work group considered the strength and quality of the evidence, patient preferences, and benefits versus harms on critical outcomes before making consensus recommendations.

RECOMMENDATIONS

The revised CPG includes 52 recommendations on evaluation, pharmacotherapy, invasive interventions, and nonpharmacologic interventions for selected primary and secondary headache disorders. In addition to triptans and aspirin-acetaminophen-caffeine, newer calcitonin gene-related peptide (CGRP) inhibitors (gepants) are options for treatment of acute migraine. Medications to prevent episodic migraine (EM) include angiotensin-receptor blockers, lisinopril, magnesium, topiramate, valproate, memantine, the newer CGRP monoclonal antibodies, and atogepant. AbobotulinumtoxinA can be used for prevention of chronic migraine but not EM. Gabapentin is not recommended for prevention of EM. Ibuprofen (400 mg) and acetaminophen (1000 mg) can be used for treatment of TTH, and amitriptyline for prevention of chronic TTH. Physical therapy or aerobic exercise can be used in management of TTH and migraines.

Associations between adherence to Mediterranean dietary pattern and frequency, duration, and severity of migraine headache: A cross-sectional study

BACKGROUND

The present study was conducted to explore the association between adherence to Mediterranean dietary pattern and migraine headache features including frequency, duration, and severity, as well as patients' migraine-related disabilities among the Iranian population diagnosed with migraine.

METHODS

 In the present cross-sectional study on 262 migraine patients aged 20-50 years old, a validated 168-item, food frequency questionnaire was used to assess the dietary intakes of participants. The Mediterranean diet score was calculated for each subject using nine pre-defined dietary components and ranged from 0-9. The headache severity, duration, frequency, migraine headache index score (MHIS), and headache impact test-6 (HIT-6) were measured using related questionnaires.

RESULTS

 After controlling for potential confounders, Mediterranean diet tended to be associated with lower headache frequency (β = -1.74, 95% CI: -3.53,0.03) and duration (β = -0.28, 95% CI: -0.59, -0.02) and was significantly associated with lower MHIS (β = -29.32, 95% CI: -51.22, -7.42), and HIT-6 score (β = -2.86, 95% CI: -5.40, -0.32) for those in the highest category of Mediterranean diet scores compared to the lowest category. A subgroup analysis of women also revealed a negative association between Mediterranean diet and headaches frequency (β = -2.30, 95% CI: -4.27, -0.32), duration (β = -0.42, 95% CI: -0.78, -0.07), scores of MHIS (β = -47.44, 95% CI: -71.90, -22.99), and HIT-6 (β = -3.45, 95% CI: -6.29, -0.61), after controlling for potential confounders.

CONCLUSIONS

The present study suggests that adherence to the Mediterranean dietary pattern is associated with lower headache frequency, duration, MHIS, and HIT-6 score.

The Primary Care Management of Headache: Synopsis of the 2020 U.S. Department of Veterans Affairs and U.S. Department of Defense Clinical Practice Guideline

INTRODUCTION

In June of 2020, the U.S. DVA and DoD approved a new joint clinical practice guideline for assessing and managing patients with headache. This guideline provides a framework to evaluate, treat, and longitudinally manage the individual needs and preferences of patients with headache.

METHODS

In October of 2018, the DVA/DoD Evidence-Based Practice Work Group convened a guideline development panel that included clinical stakeholders and conformed to the National Academy of Medicine's tenets for trustworthy clinical practice guidelines.

RESULTS

The guideline panel developed key questions, systematically searched and evaluated the literature, created a 1-page algorithm, and advanced 42 recommendations using the Grading of Recommendations Assessment, Development, and Evaluation system.

CONCLUSION

This synopsis summarizes the key features of the guideline in three areas: prevention, assessing and treating medication overuse headache, and nonpharmacologic and pharmacologic management of headache.

Effects of the Dietary Approaches to Stop Hypertension (DASH) diet on clinical, quality of life, and mental health outcomes in women with migraine: A randomised controlled trial

The relationship between the Dietary Approaches to Stop Hypertension (DASH) diet and clinical, quality of life, and mental health outcomes in migraine is unknown. To address this knowledge gap, we conducted a parallel-group, randomised controlled trial to evaluate the effect of the DASH diet on these health outcomes in women with migraine. Of 102 eligible women (20-50 years), 51 randomised to the DASH and 51 to the usual dietary advice (control) groups completed a 12-week intervention. The DASH diet was designed using a 7-day menu cycle to provide 15-20% of total daily energy requirements from proteins, 25-30% from fats, and 55-60% from carbohydrates. Dietary records and serum vitamin C levels were used to assess women's compliance with the DASH diet. The clinical symptoms of migraine (i.e., frequency, duration, severity) and quality of life and mental health (i.e., depression, anxiety, stress) outcomes were assessed in groups pre-and post-intervention. We observed greater decreases in the frequency (-3.00 vs. -1.40, P=0.025) and severity (-1.76 vs. -0.59, P<0.001) of migraine in the DASH vs. control group post-intervention. Similarly, the DASH group exhibited a tendency toward greater decreases in migraine duration (-0.58 vs -0.33 days, P=0.053) and had lower scores of depression (-4.50 vs. -2.73, P=0.019) and stress (-5.84 vs -2.98, P=0.011) vs. controls. However, the quality of life and anxiety outcomes remained comparable in groups post-intervention. Together, evidence supports the benefits of the DASH diet on improving migraine health outcomes in reproductive-aged women. Further research is needed to confirm our findings.

The effects of the dietary approaches to stop hypertension (DASH) diet on oxidative stress and clinical indices of migraine patients: a randomized controlled trial

AIMS

The relationship between the Dietary Approaches to Stop Hypertension (DASH) diet and oxidative stress (OS) in patients diagnosed with migraine is unknown and remains to be examined. Hence, we conducted a parallel-group, randomized controlled trial to investigate this issue.

METHODS

Of the 102 women who met all the inclusion criteria, 51 individuals were randomized to the DASH diet group and 51 to the usual dietary advice group to receive allocated intervention for three months. In order to assess the compliance of participants to the DASH diet, dietary records, and serum vitamin C levels were examined. Parameters of OS status (e.g. nitric oxide (NO), total antioxidant capacity (TAC), total oxidative status (TOS), malondialdehyde (MDA), and oxidative stress index (OSI)) and clinical indices of migraine (e.g. migraine index (MI), headache dairy result (HDR), and migraine headache index score (MHIS)) were assessed at the beginning and the end of the study.

RESULTS

There was a significant reduction in NO (-5.75 vs. + 4.18, P = 0.025) and TOS (-1.55 vs. + 0.71, P = 0.034), and a marginally significant reduction in OSI (-0.10 vs. + 0.14, P = 0.060) in the DASH group compared with the control. Compliance with the DASH diet resulted in a significant decrease in the score of MI (-31.33 vs. - 15.09), HDR (-5.04 vs. -2.51), and MHIS (-44.21 vs. -26.74). Moreover, no significant change was observed in TAC, MDA, and total thiol content.

CONCLUSION

This type of dietary approach can be considered as a complementary treatment for migraine patients, also further investigations are needed to replicate our findings.Trial registration: Iranian Registry of Clinical Trials identifier: IRCT20121216011763N38.

The quality and inflammatory index of the diet of patients with migraine

BACKGROUND

The association between diet and migraine has been reported in the literature, but only a few studies have evaluated whether the diet consumed by patients with migraine differs from individuals without migraine.

OBJECTIVE

Herein, we aimed to investigate whether the quality and the Dietary Inflammatory Index (DII) of diet consumed by migraine patients differ from that consumed by healthy controls. We also evaluated whether the severity of migraine and headache frequency were associated with these parameters.

METHODS

Patients of both sexes, aged between 18 and 65, with episodic migraine and healthy controls were enrolled in this cross-sectional study. Disability and impact caused by migraine and depressive symptoms were evaluated. Dietary intake was assessed using a 24-hour dietary recall and a three-day non-consecutive food record. The quality of the diet was calculated using the Healthy Eating Index (HEI)-2015 adapted to the Brazilian population, and DII was calculated based on the method developed by Shivappa et al. (2014).

RESULTS

Ninety patients with migraine and 62 individuals without migraine were included in this study. The groups did not differ regarding age, sex, marital status, years of schooling, anthropometric characteristics, and depressive symptoms. Patients with migraine had lower HEI total score than controls, indicating that these patients have a lower quality of the diet. Patients with migraine also had higher DII than controls. Nevertheless, HEI and DII scores did not correlate with migraine frequency and severity.

CONCLUSION

This study corroborates the view that the characteristics of the diet might be involved in migraine pathophysiology.

Dietary trigger factors of migraine and tension-type headache in a South East Asian country

BACKGROUND

The literature on the dietary trigger factors of headache among the South East Asians is limited.

OBJECTIVE

The objective of the study was to examine the dietary trigger factors of migraine and tension-type headache (TTH) in Malaysian patients, consisting of Malays, Chinese and Indians.

METHODS

In this prospective cross-sectional study, patients presenting with migraine and TTH to a neurology clinic between April 2010 and June 2017 were recruited. The patients were given a comprehensive dietary list consisting of 25 specified types of food and drink items as well as other unspecified types of food and drink items which were possible dietary triggers. The data on these dietary triggers and missing meals were collected.

RESULTS

A total of 684 patients with headache (319 migraine and 365 TTH patients) were recruited. One hundred and fifty-eight (23.1%) patients had missing meals as trigger. Two hundred and fifty-five (37.3%) patients had dietary triggers; 141 (44.2%) patients with migraine and 114 (31.2%) patients with TTH had dietary triggers. Eighty-four (52.8%) Malay, 28 (41.8%) Chinese, 25 (32.5%) Indian migraine patients and five (38.5%) migraine patients from other ethnic groups, had dietary triggers. Some 58 (40.0%) Malay, 27 (25.2%) Chinese, 22 (23.9%) Indian patients and 7 (29.2%) patients from other ethnic groups with TTH had dietary triggers. The most common dietary trigger factors were coffee (19.9%), chocolate (7.5%) and food rich in monosodium glutamate (5.6%). Logistic regression showed that chocolate (OR 2.16, 95% CI 1.06-4.41, p = 0.035) and coffee (OR 1.73, 95% CI 1.12-2.68, p = 0.014) were significantly associated with migraine compared to TTH.

CONCLUSION

Chocolate and coffee significantly triggered migraine compared to TTH. Inter-ethnic differences were observed for dietary trigger factors.
