Is migraine really a female disorder?
BARCELONA, SPAIN — Migraine is widely considered a predominantly female disorder. Its frequency, duration, and severity tend to be higher in women, and women are also more likely than men to receive a migraine diagnosis. However, gender expectations, differences in the likelihood of self-reporting, and problems with how migraine is classified make it difficult to estimate its true prevalence in men and women.
Different Symptoms
Headache disorders are estimated to affect 50% of the general population ; tension-type headache and migraine are the two most common. According to epidemiologic studies, migraine is more prevalent in women, with a female-to-male ratio of 3:1. There are numerous studies of why this might be, most of which focus largely on female-related factors, such as hormones and the menstrual cycle.
“Despite many years of research, there isn’t one clear factor explaining this substantial difference between women and men,” said Tobias Kurth of Charité – Universitätsmedizin Berlin, Germany. “So the question is: Are we missing something else?”
One factor in these perceived sex differences in migraine is that women seem to report their migraines differently from men, and they also have different symptoms. For example, women are more likely than men to report severe pain, and their migraine attacks are more often accompanied by photophobia, phonophobia, and nausea, whereas men’s migraines are more often accompanied by aura.
“By favoring female symptoms, the classification system may not be picking up male symptoms because they’re not being classified in the right way,” Dr. Kurth said, with one consequence being that migraine is underdiagnosed in men. “Before trying to understand the biological and behavioral reasons for these sex differences, we first need to consider these methodological challenges that we all apply knowingly or unknowingly.”
Christian Lampl, professor of neurology at Konventhospital der Barmherzigen Brüder Linz, Austria, and president of the European Headache Federation, said in an interview, “I’m convinced that this 3:1 ratio which has been stated for decades is wrong, but we still don’t have the data. The criteria we have [for classifying migraine] are useful for clinical trials, but they are useless for determining the male-to-female ratio.
“We need a new definition of migraine,” he added. “Migraine is an episode, not an attack. Attacks have a sudden onset, and migraine onset is not sudden — it is an episode with a headache attack.”
Inadequate Menopause Services
Professor Anne MacGregor of St. Bartholomew’s Hospital in London, United Kingdom, specializes in migraine and women’s health. She presented data showing that migraine is underdiagnosed in women; one reason being that the disorder receives inadequate attention from healthcare professionals at specialist menopause services.
Menopause is associated with an increased prevalence of migraine, but women do not discuss headache symptoms at specialist menopause services, Dr. MacGregor said.
She then described unpublished results from a survey of 117 women attending the specialist menopause service at St. Bartholomew’s Hospital. Among the respondents, 34% reported experiencing episodic migraine and an additional 8% reported having chronic migraine.
“Within this population of women who were not reporting headache as a symptom [to the menopause service until asked in the survey], 42% of them were positive for a diagnosis of migraine,” said Dr. MacGregor. “They were mostly relying on prescribed paracetamol and codeine, or buying it over the counter, and only 22% of them were receiving triptans.
“They are clearly being undertreated,” she added. “Part of this issue is that they didn’t spontaneously report headache as a menopause symptom, so they weren’t consulting for headache to their primary care physicians.”
Correct diagnosis by a consultant is a prerequisite for receiving appropriate migraine treatment. Yet, according to a US study published in 2012, only 45.5% of women with episodic migraine consulted a prescribing healthcare professional. Of those who consulted, 89% were diagnosed correctly, and only 68% of those received the appropriate treatment.
A larger, more recent study confirmed that there is a massive unmet need for improving care in this patient population. The Chronic Migraine Epidemiology and Outcomes (CaMEO) Study, which analyzed data from nearly 90,000 participants, showed that just 4.8% of people with chronic migraine received consultation, correct diagnosis, and treatment, with 89% of women with chronic migraine left undiagnosed.
The OVERCOME Study further revealed that although many people with migraine were repeat consulters, they were consulting their physicians for other health problems.
“This makes it very clear that people in other specialties need to be more aware about picking up and diagnosing headache,” said MacGregor. “That’s where the real need is in managing headache. We have the treatments, but if the patients can’t access them, they’re not much good to them.”

Medication overuse headache a pain to treat
BARCELONA, SPAIN — Around half of all patients with chronic headache or migraine overuse their medication, leading to aggravated or new types of headaches. “Medication overuse headache” is the third most frequent type of headache, affecting some 60 million people or around 1% of the world’s population.
“It’s a big problem,” Sait Ashina, MD, of Beth Israel Deaconess Medical Center, Boston, Massachusetts, told the audience in an opening plenary at the 17th European Headache Congress in Barcelona.
Medication overuse headache is characterized by an increasing headache frequency and progressive use of short-term medication and is recognized as a major factor in the shift from episodic to chronic headache.
It is often underrecognized; however, educating doctors and patients is a crucial element of effective treatment. Recognition that headache medication is being overused is a crucial first step to treatment, followed by advising the patient to discontinue the medication. But this poses its own problems, as it can cause withdrawal symptoms.
According to a longitudinal population-based study published in 2008, most patients overuse acetaminophen or paracetamol, followed by nonsteroidal anti-inflammatory drugs and 5-hydroxytriptamine agonists (triptans) and, in the United States, barbiturates and opioids.
What’s the Best Treatment Strategy?
Medication overuse headache is often treated by complete withdrawal from medication, but the withdrawal symptoms can be severe. They include nausea and vomiting, arterial hypertension, tachycardia, sleep disturbances, anxiety, and restlessness, with their duration and severity depending solely on the type of headache medication that has been overused.
There is, however, no consensus on how best to treat medication overuse headache — withdrawal plus preventive treatment, preventive treatment without withdrawal, and withdrawal with optional preventive treatment 2 months after withdrawal. The findings showed that all three strategies were effective. But the research team concluded that withdrawal combined with preventive medication from the start of withdrawal was the recommended approach.
The electronic headache diary has proved to be very useful, as it can aid accurate diagnosis by providing clear insights into a patient’s condition. Information from the diary is more reliable than self-reports because patients often underestimate the frequency of their headaches, migraines, and use of medication.
Patients who are treated for medication overuse headache tend to have a high relapse rate. So, the electronic headache diary can also be very useful for follow-up by alerting patients and clinicians when headaches and medication overuse are increasing again.
“After diagnosing medication overuse or medication overuse headache, we advise our patients to discontinue the medication,” said Judith Pijpers of Leiden University Medical School, the Netherlands. “This provides clinically relevant improvements in headache frequency in a majority of patients and a significant reduction in headache days.”
In 2019, Dr. Pijpers and her colleagues published the results of a double-blind randomized controlled trial showing that botulinum toxin A, which is widely used to treat chronic migraine, has no additional benefit over acute withdrawal in patients with chronic migraine and medication overuse.
“We saw no difference between the groups during both the double-blind and the open label phase,” said Dr. Pijpers. “And that is why we do not give patients botulinum toxin A during withdrawal.”
A further trial within the botox study showed modest benefits for behavioral intervention by a headache nurse comprising education, motivational interviewing, and value-based activity planning during withdrawal therapy.
Patients can be stratified to some extent based on the type of headache they have and the medication they are taking for it.
“You can predict [a patient’s response] to some extent from the type of medication they overuse and the type of underlying primary headache,” Dr. Pijpers said in an interview.
“Those with underlying tension-type headache have different withdrawal symptoms than those with underlying migraine, and the withdrawal symptoms tend to be somewhat shorter if a patient overuses triptans compared to analgesics.”
Predicting Patients’ Responses to Migraine Medication
Dr. Pijpers and her colleagues recently published the results of a cohort study suggesting that cutaneous allodynia may predict how patients with migraine respond to withdrawal therapy. Nearly 75% of the 173 patients enrolled in the study reported experiencing allodynia — pain caused by a stimulus that does not normally cause pain. The study showed that absence of allodynia was predictive of a good outcome for patients after withdrawal therapy and of reversion from chronic to episodic migraine.
The ability to accurately predict patients’ responses could pave the way for personalized treatments of medication overuse headache.
