Diabetes Drug Liraglutide Shows Promise in Reducing Migraine Days

Helsinki, Finland – A medication typically used to treat diabetes is showing remarkable promise in reducing the frequency of migraines. Results from a new study, unveiled today at the European Academy of Neurology (EAN) Congress 2025, indicate that the drug liraglutide can cut monthly migraine days by more than half.

The research, conducted at the Headache Center of the University of Naples “federico II,” explored the impact of the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide on 26 adults dealing with both obesity and chronic migraines. Chronic migraine is defined as experiencing 15 or more headache days per month.

Important reduction in Migraine Frequency

The study participants reported an average decrease of 11 headache days per month after treatment with liraglutide. Furthermore,their scores on the Migraine Disability Assessment Test (MIDAS) dropped by 35 points. This considerable reduction signifies a clinically relevant enhancement in their ability to function at work, in academic pursuits, and in social settings.

Glucagon-like peptide-1 (GLP-1) agonists have recently revolutionized treatment strategies for various conditions,including diabetes and cardiovascular ailments. Liraglutide, in particular, aids in managing type 2 diabetes by lowering blood sugar levels and promoting weight loss through appetite suppression and reduced energy consumption.

Though the participants’ body-mass index saw a slight dip (from 34.01 to 33.65), this shift wasn’t statistically noteworthy. An analysis showed that this slight weight reduction did not correlate with the decrease in headache frequency,bolstering the theory that it is indeed the modulation of pressure,rather than weight loss,that provides the therapeutic effect.

improved Quality of Life

“Most patients felt better within the first two weeks and reported quality of life improved significantly,” said lead researcher Dr. Simone Braca. “The benefit lasted for the full three-month observation period, even though weight loss was modest and statistically non-significant.”

Before the study began, patients underwent screening to rule out papilledema (optic disc swelling caused by heightened intracranial pressure) and sixth nerve palsy, thereby excluding idiopathic intracranial hypertension (IIH) as a contributing variable. Emerging evidence suggests a strong connection between minor elevations in intracranial pressure and the occurrence of migraine attacks.

Did You know? Idiopathic Intracranial Hypertension (IIH) is also being effectively treated with GLP-1 receptor agonists.

GLP-1-receptor agonists like liraglutide diminish cerebrospinal fluid secretion and have demonstrated efficacy in treating IIH. Building upon these findings, Dr.Braca and his team posited that leveraging this mechanism could mitigate cortical and trigeminal sensitization that precipitate migraines.

Intracranial Pressure and Migraines: A New Pathway

“We think that, by modulating cerebrospinal fluid pressure and reducing intracranial venous sinuses compression, these drugs produce a decrease in the release of calcitonin gene-related peptide (CGRP), a key migraine-promoting peptide,” Dr. Braca explained. “That would pose intracranial pressure control as a brand-new, pharmacologically targetable pathway.”

Key Finding	Details
Migraine Day Reduction	Average of 11 fewer headache days per month
MIDAS Score Betterment	35-point decrease, indicating better functionality
Primary Mechanism	Modulation of cerebrospinal fluid pressure
Side Effects	Mild gastrointestinal issues in 38% of participants

Next Steps in Research

In the study, 38% of participants experienced mild gastrointestinal side effects, mainly nausea and constipation; though, these issues did not lead anyone to discontinue the treatment.

Following this initial 12-week pilot study, the research team in Naples, under the guidance of Professor Roberto De Simone, is organizing a randomized, double-blind trial that will involve direct or indirect measurement of intracranial pressure. “We also want to determine whether other GLP-1 drugs can deliver the same relief,possibly with even fewer gastrointestinal side effects,” Dr. Braca added.

If these findings are substantiated, GLP-1-receptor agonists could present a novel treatment avenue for the estimated one in seven individuals globally who grapple with migraines, particularly those for whom current preventive measures are ineffective.Given liraglutide’s established use in treating type 2 diabetes and obesity, it may signify a promising instance of drug repurposing within neurology.

Pro Tip: Consult with your healthcare provider before starting any new medication, especially if you have pre-existing health conditions.

The Broader Impact of Glp-1 Agonists

Glp-1 agonists, initially developed for diabetes management, have showcased potential extending to other neurological conditions.The ability of these drugs to modulate intracranial pressure opens new avenues for treating conditions beyond migraines, such as idiopathic intracranial hypertension. Researchers are actively exploring these possibilities, aiming to refine treatments and minimize side effects.

Future of Migraine Treatment

The exploration of intracranial pressure as a therapeutic target could fundamentally change how migraines are managed. As ongoing trials investigate various Glp-1 drugs, there is hope for more effective and tolerable treatments. This approach may particularly benefit those who have not found relief through conventional migraine therapies.

Frequently Asked Questions About Liraglutide and Migraines

Can liraglutide completely eliminate migraines?

While liraglutide has shown promise in reducing the frequency and severity of migraines, it may not eliminate them entirely. The extent of relief can vary among individuals.

What are the common side effects of liraglutide?

The most commonly reported side effects in the study were mild gastrointestinal issues such as nausea and constipation. These side effects typically did not lead to treatment discontinuation.

Is liraglutide safe for long-term use in migraine treatment?

The long-term safety and efficacy of liraglutide for migraine treatment are still being investigated.Ongoing and future clinical trials will provide more insights into this aspect.

How does liraglutide compare to other migraine medications?

Liraglutide offers a novel mechanism of action by modulating cerebrospinal fluid pressure, which differs from many traditional migraine medications. This may make it a valuable option for those who haven’t responded well to other treatments. GLP-1 agonists, like liraglutide, have demonstrated effectiveness in reducing pain mediators and inflammation linked to migraine in animal models.

Who is a good candidate for liraglutide treatment for migraines?

Individuals with chronic migraines, particularly those who are also obese or have type 2 diabetes, might be good candidates. However, it is essential to consult with a healthcare provider to determine individual suitability.

How quickly can one expect to see results with liraglutide in migraine treatment?

In the study, many patients reported feeling better within the first two weeks of treatment. The benefits appeared to sustain over the three-month observation period.

Are there any contraindications for using liraglutide in migraine patients?

Patients should be screened to rule out papilledema and sixth nerve palsy. Individuals with a history of certain medical conditions should discuss this with their healthcare provider before starting liraglutide.
