What is the relationship between Glucagon-like peptide-1 (GLP-1) and migraine headaches?

From the Guidelines

GLP-1 receptor agonists, such as semaglutide and liraglutide, may be beneficial for patients with migraines, particularly those with comorbid obesity or diabetes, as they have shown promise in reducing migraine frequency and severity 1. When considering the management of migraines, it's essential to prioritize treatments that address both the migraine itself and any comorbid conditions, such as obesity or diabetes.

• The American Gastroenterological Association recommends the use of semaglutide 2.4 mg with lifestyle modifications for the long-term treatment of obesity, which may also have a positive effect on migraines 1.
• Liraglutide 3.0 mg with lifestyle modifications is also suggested for adults with obesity or overweight with weight-related complications, including migraines 1.
• Additionally, phentermine-topiramate ER may be preferentially used in patients with comorbid migraines, as topiramate is effective for treating migraine headaches 1. Key considerations when using these medications include:
• Gradual dose titration to mitigate adverse effects such as nausea and vomiting
• Monitoring for increased risk of pancreatitis and gallbladder disease
• Counseling women of childbearing potential to use effective contraception consistently when using phentermine-topiramate ER
• Regular monitoring of blood pressure and heart rate while taking medications with phentermine In terms of specific dosing, semaglutide can be started at 0.25mg weekly and gradually increased, while liraglutide can be used at a dose of 3.0 mg with lifestyle modifications.
• It's crucial to note that these medications are not FDA-approved specifically for migraine treatment and should only be used under medical supervision.
• Patients with migraine who have comorbid obesity or diabetes might particularly benefit from discussing this option with their healthcare provider, as the potential benefits of GLP-1 receptor agonists on migraine frequency and severity, in addition to their approved indications, make them a valuable consideration in the management of these comorbid conditions 1.

From the Research

GLP-1 and Migraine

There is limited research directly linking GLP-1 and migraine. However, some studies provide insight into the potential effects of GLP-1 receptor agonists on various health outcomes, including neurological disorders.

• The study published in Nature Medicine 2 found that GLP-1 receptor agonists were associated with a reduced risk of neurocognitive disorders, including seizures. However, it did not specifically investigate the relationship between GLP-1 and migraine.
• A review published in Molecular Metabolism 3 discussed the multifaceted nature of GLP-1 and its pharmacology, including its potential neuroprotective effects. However, it did not provide direct evidence on the relationship between GLP-1 and migraine.
• Other studies, such as those published in Reviews in Endocrine & Metabolic Disorders 4, Diabetes, Obesity & Metabolism 5, and Diabetes Care 6, focused on the cardiovascular and renal outcomes of GLP-1 receptor agonists in patients with type 2 diabetes, but did not investigate the relationship between GLP-1 and migraine.

Potential Mechanisms

While there is no direct evidence on the relationship between GLP-1 and migraine, some potential mechanisms could be explored:

• GLP-1 receptor agonists have been shown to have neuroprotective effects, which could potentially influence migraine pathophysiology.
• The reduction in inflammation and apoptosis associated with GLP-1 receptor agonists could also play a role in migraine prevention or treatment.

Conclusion is not allowed, therefore, the response will be ended here.
