Headache & Migraine

The use of opiates in the treatment of headache has a controversial history, and it remains a matter of debate today. Some believe that the medications, though risky, can be a useful tool in the neurologist’s treatment arsenal, while others argue that opioids are just too risky when there are other, safer alternatives available.

Those were the cruxes of arguments put forward by Paul Rizzoli, MD, and Christopher H. Gottschalk, MD, who conducted individual talks at the 2021 Scottsdale Headache Symposium. Dr. Rizzoli, associate professor of neurology at Harvard Medical School, Boston, argued in favor of the use of opioids and butalbital-containing medications. Dr. Gottschalk, assistant professor of neurology at Yale University, New Haven, Conn., argued against their use.

In certain situations opioids are worth the risk

Whether or not to use opioids in the treatment of headache is “a reasonable question, because these medications can clearly be seen as having risk. So perhaps another way to frame this question is as a risk-benefit issue. Are these medications worth the risk? How useful is the benefit of opioids, if the consequence is dependence or addiction?” Dr. Rizzoli began.

Although reviews show effectiveness of opioids in treating migraine, a three-part review in 2012 found greater efficacy of dihydroergotamine (DHE), ketorolac, and chlorpromazine. That’s not surprising, said Dr. Rizzoli, since those competing drugs are migraine-specific.

Dr. Rizzoli quoted a 2014 review indicating that there were incomplete data on the relative efficacy of opioids versus other analgesics, and for some patients opioids would likely be the optimal treatment, such as those who have contraindications to ergot-type medications or neuroleptic medications, pregnant women, or patients who don’t respond to other medications.

Dr. Rizzoli noted that The International Association for the Study of Pain has concluded that no other oral medications provide immediate and effective pain relief, and that short-term use rarely leads to addiction.

“So, to me, the answer is not to avoid opioids or outlaw them but instead to use them judiciously and infrequently, and in a short term or rescue fashion,” said Dr. Rizzoli.

He pointed out that physicians accept risks of other medications, and act to mitigate those risks. He said that risk mitigation with opioids can take the form of avoiding prescriptions in some situations, like when patients have a personal or family history of substance abuse, or in cases of some behavioral or emotional disorders.

Dr. Rizzoli went on to discuss the use of butalbital, which acts as a CNS depressant and has a variety of effects, including sedation, anxiolytic, hypnotic, and antiepileptic effects, but it is only a weak analgesic, but it nevertheless works in headache, said Dr. Rizzoli, citing patient reports and personal experience.

“It’s difficult to appreciate this theme of efficacy behind all the hype in the literature and in the press against butalbital, and the fact that it has not been adequately studied. But I would submit that the fact that we are even having this discussion is support enough for the use of butalbital. If butalbital either didn’t work or was simply a drug of abuse, it would likely have faded away by now,” said Dr. Rizzoli. He conceded that butalbital can be overused and may lead episodic headache to become chronic daily headache, but he noted that Seymour Solomon, MD, professor emeritus at Albert Einstein College of Medicine, New York, has estimated that removal of butalbital from the market would reduce chronic headache in the general population by only a small fraction of one percent.

Butalbital also has another interesting effect, which is that patients may quickly return to normal functioning after the headache resolves. “Maybe this is all due to management of anxiety, the presumed mechanism of action of barbiturates. So, instead of lobbying for its removal, I would propose that we should take a closer look at what’s going on here, and what the mechanism of action of this fairly interesting compound might be,” said Dr. Rizzoli.

Dr. Rizzoli also said there is some evidence that migraine-specific drugs also affect the tolerance to opioid drugs. “Somehow, they seem to interact with the opioid pain system. If that’s true, the implication is that you probably cannot escape the opioid receptors in the management of migraine,” said Dr. Rizzoli.

Ultimately, he supports the judicious use of opioids and butalbital containing-medications for headache relief. “My argument is that it is just too simplistic to cease use of these meds. Yes, they should be used in a restricted and careful way, but not abandoned,” said Dr. Rizzoli.
 

Opiates should be avoided

Following Dr. Rizzoli’s presentation, Dr. Gottschalk presented an argument against the use of opioids in the treatment of headache.

He began by quoting the ABIM Choosing Wisely Campaign of 2012, which concluded that fioricet and narcotics should be avoided in headache unless the patient is desperate. “As a headache specialist, I can tell you that I have not faced situations sufficiently desperate to use any of these. The American Headache Society in a series of evidence assessments has concluded similarly, that they are of no use,” said Dr. Gottschalk.

Opiates and barbiturates may also increase risk of migraine chronification. One study found that triptans are associated with low rates of chronification, at just a few percent when used fewer than 4 days a month, and about 20% per year when used 10-14 days per month. Opiate use showed a broadly similar pattern, while barbiturates showed a particularly alarming pattern: “Every level of use was associated with astronomically high rates and measurably higher at the highest level of use. For opiates, the odds ratio was about 2 – statistically significant. For barbiturates it was clearly greater than 2, whereas with triptans, the odds ratio showed a nonsignificant, slight increase in risk. And for NSAIDs, the odds ratio was, if anything, less than 1,” said Dr. Gottschalk.

He also discussed aspects of behavioral pharmacology, in which positive reinforcement associated with decreased headache may encourage repeated use of the drug. “Given these, it should be no surprise to anyone that emergency room treatment with opiates for acute migraine is clearly associated with increased recidivism for patients given those drugs,” said Dr. Gottschalk.

Opiate use is associated with increased pain sensitivity, and in the case of migraine, it may interfere with the activity of other treatments.

As for butalbital-containing compounds, they are positive-reinforcing drugs, and they are not indicated for migraine, only tension headache. There is no evidence of benefit in migraine, but butalbital is anxiolytic, which could lead an individual to increase its use.

A recent meta-analysis of therapies for episodic migraine found that hydromorphone and meperidine are less effective than standard therapies such as prochlorperazine or metoclopramide. Another study suggested that opioid use may interfere with the efficacy of NSAIDs in the emergency room environment, while a post hoc analysis of rizatriptan clinical trials found that recent opiate use was associated with a lower response rate, and the effect was more pronounced in women.

Among patients with chronic migraine, a 2004 study found that opiates were the most commonly used medication, and other studies found that chronic migraine does not arise in nonmigraine patients treated with opiates, “suggesting that migraine is specifically prone to opiate-induced hyperalgesia of migraine itself,” said Dr. Gottschalk.

Even under careful monitoring, misuse occurs in more than 50% of patients, “suggesting that even under the best circumstances, it is difficult to use this class of drugs safely in long term,” said Dr. Gottschalk.

He pointed out that the risk of drug addiction rises with various clinical and socioeconomic factors, including living in impoverished environments, adverse childhood experiences, low socioeconomic status, exposure to pollutants, and stressors. “In other words, all features associated with systemic racism are clearly associated with an increased risk of addiction,” said Dr. Gottschalk. Other factors include availability of the drug, such as whether or not a physician prescribes it, and repeated use.

These concerns, combined with positive-reinforcing properties of opiates and association with migraine progression and refractoriness, and the lack of progression risk found with use of NSAIDs and triptans, and the fact that effective acute therapy is associated with a lower risk of progression, argue against the use of opiates, said Dr. Gottschalk.

There is even a potential risk that the experience of migraine and its relief due to self-administration may become a rewarding experience that propagates the problem. It’s possible that anticipatory anxiety related to fear stressors could lead to migraine, or to physical sensations interpreted as migraine prodrome. “[It] raises the question of whether or not positive reinforcement by drugs makes migraine itself a rewarding experience and therefore more likely to occur as a cue for drug self-administration. The question I pose is: Is there any reason to test this theory in drugs of no proven benefit in the treatment of migraine? I would say very clearly, No,” said Dr. Gottschalk.
 

Clarifying the finer points of the debate

In the Q&A session after the talk, Dr. Rizzoli said that he doesn’t advocate for long-term use of opiates, except in rare cases where the diagnosis gets changed to a chronic pain syndrome. “We’re talking about intermittent use for treatment of an acute event. Do we put limits on them? I think the answer is clearly Yes, and the limits are more strict than those for triptans. My own sense as a clinician is I want all of the available tools. From a clinical perspective, there are a large number of people who do just fine with intermittent use of these medicines, and so I wouldn’t restrict them,” said Dr. Rizzoli.

Dr. Gottschalk agreed that opiates may make sense for some patients, but expressed concerns about any and all physicians prescribing them. “The part about the tools is partly a question of: Who gets to use them? In the hands of a headache specialist in those isolated cases with careful restrictions, sure. But what I’m making is a slippery slope argument: What we know is that in emergency rooms, these are used routinely, and that [those] patients are precisely the ones who are at higher risk of addiction. So in some sense, I’m just saying I think we need to have much clearer boundaries,” he said.

Dr. Rizzoli has no relevant financial disclosures. Dr. Gottschalk has been on the advisory boards of Alder, AbbVie, Amgen/Novartis, Biohaven, Theranica, Upsher-Smith, Axsome, Vorso, Currax, and Impel. He has been a consultant for Alder, Alexion, and Spherix Global Insights. He has received research support from Relivion.

‘Grainy’ or ‘pixelated’ vision can be an alarming symptom for patients. The phenomenon is called visual snow, and although it was first described only recently, it is fairly common.

“This is a symptom of vision where patients describe numerous flickering dots throughout their vision. Sometimes they’ll use the term grainy or pixelated vision. Many times there’s a dynamic moving component to this. Many patients will describe this as like a TV static overlay on their vision,” Carrie Robertson, MD, said during a presentation on the topic at the 2021 Scottsdale Headache Symposium. Dr. Robertson is a neurologist at the Mayo Clinic in Rochester, Minn.

“It turns out that a little over 3% of us probably see this in our vision. So even if you haven’t seen this in the clinic yet, it’s likely that you will in the future,” said Dr. Robertson.

The first report describing visual snow appeared in 1995, among migraine patients. As of 2014 there were only 10 cases described in the literature. Although the condition was initially thought of as an unusual feature of migraine, a 2014 combined chart review and survey found that 15 of 22 patients had additional visual symptoms, such as photophobia or difficulty with night vision. Twenty of the 22 patients had comorbid migraine. Other symptoms include visual ghosts that persist after looking away from an object, as well as a higher frequency of experiencing floaters.

Symptoms aren’t restricted to the visual domain. Migraine, tinnitus, dizziness, and impaired concentration also occur.

The condition is more common than many suspect. “We used to think it was very rare. Now we assume that this was just under recognized,” said Dr. Robertson. One survey in the United Kingdom found that 3.7% of respondents reported visual snow, and 2.2% met the criteria for the syndrome.
 

A common and typically benign problem

It is a common clinical problem, according to Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program. “Almost every week I personally see somebody and then in our group, we have a whole host of them,” he said.

“When you see these patients in clinic, it’s important to remember that this is a heterogeneous disorder,” said Dr. Robertson. “Some patients will say, ‘Oh yeah, I’ve seen visual snow for as long as I can remember, I didn’t even know it was abnormal.’ Some will describe a family history of visual snow. Others will show up in clinic panicked because their visual snow just started or sometimes it’ll start after a triggering events like a head injury or hallucinogen use, and they’re worried that they’re going to go blind.”

It’s important to rule out other potential causes. Dr. Robertson’s group examined 248 cases of visual snow and found that 89 had a comorbidity that explained the condition. Issues within the retina, cornea, and the optical nerve can cause visual snow, which makes it critical that patients be seen by an ophthalmologist.

Some patients reported improvement when they stopped a new medication. “I always ask if there was a specific medicine that they started at the onset of their symptoms,” said Dr. Robertson. Other rare conditions associated with visual snow include idiopathic intracranial hypertension, posterior cortical atrophy, and even the Heidenhain variant of Creutzfeldt-Jakob disease.

In the absence of a secondary cause, and the if condition doesn’t worsen, physicians should reassure patients that the condition is typically benign. “Many of these patients are panicked that they’re going to lose their vision, and that’s what brings them to your office. It’s important to stress that visual snow is real, that you believe them, that they’re seeing what they say that they’re seeing. It’s not a migraine aura, but it’s typically benign. I like to give the analogy that it’s similar to tinnitus because I think that that’s helpful for patients to put it in that category of benign but very annoying,” said Dr. Robertson.
 

Limited treatment options

Unfortunately, there is little evidence on medications to treat the problem. According to Dr. Robertson, the best available evidence – from case reports – is for lamotrigine. Nearly 20% of patients achieve a partial response, and complete responses are rare.

Clinical trials are a possibility, but patients should be made aware that medications have the potential to worsen visual snow.

Nonpharmaceutical approaches include visual and mental distraction, along with manipulation of lighting at work and at home. Stress reduction may help, and Dr. Robertson may send patients with dizziness for visual vestibular therapy to work on visual motion desensitization exercises.

There are visual snow relief videos available on YouTube, which may provide temporary relief. “It’s probably similar to white noise therapy for tinnitus,” said Dr. Robertson.

Colored glass lenses may be helpful. “I’m having the best success at this point with FL-41 lenses. Some prefer amber, and others prefer the rose-tinted, just like migraine. I usually start with that,” said Dr. Robertson. Yellow lenses may help with nyctalopia.

She recommends that patients avoid consuming too much caffeine, and that they avoid stimulants, especially attention-deficit disorder (ADD) medications. “I’ve had a lot of patients worsen with ADD medication,” said Dr. Robertson. She also warns patients away from marijuana and hallucinogens.

There is a large community available for patients with visual snow, including more than 60 Facebook groups, and many YouTube videos of patients describing their experiences. There is even a visual snow simulator that neurologists can show patients to confirm what they are seeing. “It’s very validating for the patient,” said Dr. Robertson.

Dr. Charles noted the relatively few treatment options and poor understanding of the mechanisms behind the condition. “It’s incredibly frustrating that we have to tell them that we have so little understanding of basic mechanisms, and no really clear therapeutic strategy that we can apply across all patients and expect results,” said Dr. Charles.

The heightened interest in the condition does represent some hope. “It’s very much reassuring to people that, number one, we’re starting to understand it – but number two, that they’re not crazy. It’s very much validating to hear that it’s now a topic of much more rigorous investigation,” said Dr. Charles.

‘Grainy’ or ‘pixelated’ vision can be an alarming symptom for patients. The phenomenon is called visual snow, and although it was first described only recently, it is fairly common.

“This is a symptom of vision where patients describe numerous flickering dots throughout their vision. Sometimes they’ll use the term grainy or pixelated vision. Many times there’s a dynamic moving component to this. Many patients will describe this as like a TV static overlay on their vision,” Carrie Robertson, MD, said during a presentation on the topic at the 2021 Scottsdale Headache Symposium. Dr. Robertson is a neurologist at the Mayo Clinic in Rochester, Minn.

“It turns out that a little over 3% of us probably see this in our vision. So even if you haven’t seen this in the clinic yet, it’s likely that you will in the future,” said Dr. Robertson.

The first report describing visual snow appeared in 1995, among migraine patients. As of 2014 there were only 10 cases described in the literature. Although the condition was initially thought of as an unusual feature of migraine, a 2014 combined chart review and survey found that 15 of 22 patients had additional visual symptoms, such as photophobia or difficulty with night vision. Twenty of the 22 patients had comorbid migraine. Other symptoms include visual ghosts that persist after looking away from an object, as well as a higher frequency of experiencing floaters.

Symptoms aren’t restricted to the visual domain. Migraine, tinnitus, dizziness, and impaired concentration also occur.

The condition is more common than many suspect. “We used to think it was very rare. Now we assume that this was just under recognized,” said Dr. Robertson. One survey in the United Kingdom found that 3.7% of respondents reported visual snow, and 2.2% met the criteria for the syndrome.
 

A common and typically benign problem

It is a common clinical problem, according to Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program. “Almost every week I personally see somebody and then in our group, we have a whole host of them,” he said.

“When you see these patients in clinic, it’s important to remember that this is a heterogeneous disorder,” said Dr. Robertson. “Some patients will say, ‘Oh yeah, I’ve seen visual snow for as long as I can remember, I didn’t even know it was abnormal.’ Some will describe a family history of visual snow. Others will show up in clinic panicked because their visual snow just started or sometimes it’ll start after a triggering events like a head injury or hallucinogen use, and they’re worried that they’re going to go blind.”

It’s important to rule out other potential causes. Dr. Robertson’s group examined 248 cases of visual snow and found that 89 had a comorbidity that explained the condition. Issues within the retina, cornea, and the optical nerve can cause visual snow, which makes it critical that patients be seen by an ophthalmologist.

Some patients reported improvement when they stopped a new medication. “I always ask if there was a specific medicine that they started at the onset of their symptoms,” said Dr. Robertson. Other rare conditions associated with visual snow include idiopathic intracranial hypertension, posterior cortical atrophy, and even the Heidenhain variant of Creutzfeldt-Jakob disease.

In the absence of a secondary cause, and the if condition doesn’t worsen, physicians should reassure patients that the condition is typically benign. “Many of these patients are panicked that they’re going to lose their vision, and that’s what brings them to your office. It’s important to stress that visual snow is real, that you believe them, that they’re seeing what they say that they’re seeing. It’s not a migraine aura, but it’s typically benign.

Post–COVID-19 headache is a common and sometimes persistent problem. It may take the form of new-onset headache, or exacerbations of preexisting headache conditions such as migraine.

The Centers for Disease Control and Prevention has identified it as a sentinel symptom of COVID-19 disease. “A lot of the recommendations surrounding post-COVID headache is that if you identify a patient who has headaches associated with fever, and myalgia, and other systemic symptoms, the specificity of a COVID-19 diagnosis goes up. So [COVID-19] is a really important feature to look out for in patients with headache,” Deena Kuruvilla, MD, said during a presentation on post–COVID-19 headache at the 2021 Scottsdale Headache Symposium.

Estimates of the prevalence of headache in COVID-19 range widely, from 6.5% to 71%, but Dr. Kuruvilla has plenty of personal experience with it. “During my stint on the inpatient neurology service during the peak of COVID, I saw patients with headache being one of the most frequent complaints, [along with] dizziness, stroke, and seizure among many other neurological manifestations,” said Dr. Kuruvilla, director of the Westport (Conn.) Headache Institute.

One meta-analysis showed that 47% of patients with COVID-19 complain of headache within 30 days of diagnosis, and this drops to around 10% at 60-90 days, and around 8% at 180 days.

A survey of 3,458 patients, published in the Journal of Headache Pain, found that migraine is the most common type of post–COVID-19 headache phenotype, and patients reporting anosmia-ageusia were more likely to have post–COVID-19 headache (odds ratio [OR], 5.39; 95% confidence interval, 1.66-17.45).

A case-control study of post–COVID-19 headache patients with and without a history of migraine found that those with a history of migraine were more likely to have post–COVID-19 symptoms (OR, 1.70; P < .001) and fatigue (OR, 2.89; P = .008). “Interestingly, they found no difference in headache as post-COVID symptoms in people who had a history of migraine compared with people without a history of migraine,” said Dr. Kuruvilla.
 

Headache and COVID-19: What is the connection?

Several mechanisms have been proposed for direct invasion of the central nervous system, either via infection through the angiotensin-converting enzyme 2 (ACE-2) receptor, which is expressed in brain regions including the motor cortex, the posterior cingulate cortex, and the olfactory bulb, among other locations. Another potential mechanism is direct entry through the olfactory nerve and the associated olfactory epithelium. There are various potential mechanisms for spread among the peripheral nervous system, and the blood-brain barrier can be compromised by infection of vascular endothelial cells. According to the literature, neuronal damage seems to occur directly from viral damage rather than from the immune response, said Dr. Kuruvilla.

The virus may also gain entry to the CNS indirectly, as a result of hypoxia and metabolic disturbances, as well as dehydration and systematic inflammation. The cytokine storm associated with COVID-19 infection can activate C-reactive protein and calcitonin gene-related peptide (CGRP), which plays a key role in migraine pathology. The CGRP receptor antagonist vazegepant is being studied in a phase 2 clinical trial for the treatment of COVID-19–related lung inflammation.
 

Testing and treatment

“If I see patients with new headache, worsening headache from their baseline, or headache with systemic symptoms, I often consider screening them for COVID. If that screening is positive, I proceed with PCR testing. I also consider an MRI of the brain with and without gadolinium just to rule out any secondary causes for headache,” said Dr. Kuruvilla, noting that she has diagnosed patients with venous sinus thrombosis, ischemic stroke, and meningitis following COVID-19.

The existing literature suggests that lumbar puncture in patients with SARS-CoV-2 typically returns normal results, but Dr. Kuruvilla proceeds with it anyway with viral, bacterial, fungal, and autoimmune studies to rule out potential secondary causes for headache.

There are few studies on how to treat post–COVID-19 headache, and the general recommendation is that headache phenotype should drive treatment decisions.

In a case series, three patients with persistent headache following mild COVID-19 infection were treated with onabotulinumtoxinA and amitriptyline. They had daily headaches, along with post–COVID-19 symptoms including fatigue and insomnia. After treatment, each patient converted to episodic headaches.

One retrospective study of 37 patients found that a 5-day course of indomethacin 50 mg twice per day and pantoprazole 40 mg once per day was associated with a 50% or greater improvement in headache on the third day in 36 of the 37 patients. Five patients were free of pain by day 5.
 

A common problem

Neurologists have been involved in the treatment of COVID-19 since the beginning, and post–COVID-19 headache has added another layer. “It’s been a remarkably common clinical problem. And the fact that it’s actually reached the level of headache specialist actually shows that in some cases, it’s really quite a significant problem, in both its severity and persistence. So I think it’s a very, very significant issue,” said Andrew Charles, MD, professor of neurology at the University of California, Los Angeles, and director of the UCLA Goldberg Migraine Program.

Dr. Kuruvilla also discussed the question of whether neurological damage is due to direct damage from the virus, or indirect damage from an immune response. This was debated during the Q&A session following Dr. Kuruvilla’s talk, and it was pointed out that headache is a frequent side effect of the Pfizer and Moderna vaccines.

“It’s a huge open question about how much is direct invasion or damage or not even damage, but just change in function with the viral infection, as opposed to inflammation. The fact that very often the response to the vaccine is similar to what you see with COVID suggests that at least some component of it is inflammation. I wouldn’t commit to one mechanism or the other, but I’d say that it’s possible that it’s really both,” said Dr. Charles.

Dr. Kuruvilla has consulted for Cefaly, Neurolief, Theranica, Now What Media, and KX advisors. She has been on the speakers bureau for Abbvie/Allergan, Amgen/Novartis, and Lilly. She has been on advisory boards for Abbvie/Allergan, Lilly, Theranica, and Amgen/Novartis. Dr. Charles has no relevant financial disclosures.

Erenumab, a calcitonin-gene related peptide receptor (CGRP) inhibitor, is more tolerable and effective than topiramate for treating patients with migraine, according to data from almost 800 patients in the first head-to-head trial of its kind.

The findings suggest that erenumab may help overcome longstanding issues with migraine medication adherence, and additional supportive data may alter treatment sequencing, reported lead author Uwe Reuter, MD, professor at Charité Universitätsmedizin Berlin, and colleagues.

“So far, no study has been done in order to compare the efficacy of a monoclonal antibody targeting the CGRP pathway to that of a standard of care oral preventive drug,” the investigators wrote in Cephalalgia.

The phase 4 HER-MES trial aimed to address this knowledge gap by enrolling 777 adult patients with a history of migraine. All patients reported migraine with or without aura for at least 1 year prior to screening. At baseline, most patients (65%) reported 8-14 migraine days per months, followed by 4-7 days (24.0%), and at least 15 days (11.0%). No patients had previously received topiramate or a CGRP-targeting agent.

“HER-MES includes a broad migraine population with two-thirds of the patients in the high-frequency migraine spectrum,” the investigators noted. “Despite a mean disease duration of about 20 years, almost 60% of the patients had not received previous prophylactic treatment, which underlines the long-standing problem of undertreatment in migraine.”

The trial had a double-dummy design; patients were randomized in a 1:1 ratio to receive either subcutaneous erenumab (70 or 140 mg/month) plus oral placebo, or oral topiramate (50-100 mg/day) plus subcutaneous placebo. The topiramate dose was uptitrated over the first 6 weeks. Treatments were given for a total of 24 weeks or until discontinuation due to adverse events, which was the primary endpoint. The secondary endpoint was efficacy over months 4-6, defined as at least 50% reduction in monthly migraine days, compared with baseline. Other patient-reported outcomes were also evaluated.

After 24 weeks, 95.1% of patients were still enrolled in the trial. Discontinuations due to adverse events were almost four times as common in the topiramate group than the erenumab group (38.9% vs. 10.6%; odds ratio [OR], 0.19; confidence interval, 0.13-0.27; P less than .001). Efficacy findings followed suit, with 55.4% of patients in the erenumab group reporting at least 50% reduction in monthly migraine days, compared with 31.2% of patients in the topiramate group (OR, 2.76; 95% CI, 2.06-3.71; P less than.001).

Erenumab significantly improved monthly migraine days, headache impact test (HIT-6) scores, and short form health survey version (SF-35v2) scores, including physical and mental components (P less than .001 for all).

Safety profiles aligned with previous findings.

“Compared to topiramate, treatment with erenumab has a superior tolerability profile and a significantly higher efficacy,” the investigators concluded. “HER-MES supports the potential of erenumab in overcoming issues of low adherence in clinical practice observed with topiramate, lessening migraine burden, and improving quality of life in a broad migraine population.”
 

Superior tolerability

Commenting on the study, Alan Rapoport, MD, clinical professor of neurology at the University of California, Los Angeles, and editor-in-chief of Neurology Reviews, said this is “a very important, very well conducted trial that documents what many of us already suspected; erenumab clearly has better tolerability than topiramate as well as better efficacy.”

Dr. Rapoport, a past president of the International Headache Society, said the study highlights an area of unmet need in neurology practice.

“Despite most patients in the trial having chronic headaches for 20 years, 60% of them had never received preventive treatment,” he said, noting that this reflects current practice in the United States.

Dr. Rapoport said primary care providers in the United States prescribe preventive migraine medications to 10%-15% of eligible patients. Prescribing rates for general neurologists are slightly higher, he said, ranging from 35% to 40%, while headache specialists prescribe 70%-90% of the time.

“How can we improve this situation?” Dr. Rapoport asked. “For years we have tried to improve it with education, but we need to do a better job. We need to educate our primary care physicians in more practical ways. We have to teach them how to make a diagnosis of high frequency migraine and chronic migraine and strongly suggest that those patients be put on appropriate preventive medications.”

Barriers to care may be systemic, according to Dr. Rapoport.

“One issue in the U.S. is that patients with commercial insurance are almost always required to fail two or three categories of older oral preventive migraine medications before they can get a monoclonal antibody or gepants for prevention,” he said. “It would be good if we could change that system so that patients that absolutely need the better tolerated, more effective preventive medications could get them sooner rather than later. This will help them feel and function better, with less pain, and eventually bring down the cost of migraine therapy.”

While Dr. Reuter and colleagues concluded that revised treatment sequencing may be warranted after more trials show similar results, Dr. Rapoport suggested that “this was such a large, well-performed, 6-month study with few dropouts, that further trials to confirm these findings are unnecessary, in my opinion.”

The HER-MES trial was funded by Novartis. Dr. Reuter and colleagues disclosed additional relationships with Eli Lilly, Teva Pharmaceutical, Allergan, and others. Dr. Rapoport was involved in early topiramate trials for prevention and migraine, and is a speaker for Amgen.

Most cases of new daily persistent headache (NDPH) are moderate to severe and many feature characteristics often associated with migraine, according to a new retrospective chart review.

“Future prospective studies are needed to better understand this disabling disorder,” wrote Randolph W. Evans, MD, of Baylor College of Medicine of Houston, and Dana P. Turner, PhD, of Massachusetts General Hospital and Harvard Medical School in Boston. Their study was published Oct. 28 in Headache.

To categorize the infrequently reported clinical features of NDPH, the researchers launched a retrospective study of patients who were provisionally diagnosed with NDPH by Dr. Evans at an outpatient clinic in Houston from Sept. 1, 2011, to Feb. 28, 2020. Of the 328 patients whose diagnosis ultimately matched the ICHD-3 criteria, the average age at onset was 40.3 years (range 12-87 years). Approximately 70% were White, and nearly 66% were women. Two hundred and sixty were diagnosed with the migraine phenotype and 68 were diagnosed with the tension-type phenotype.
 

Key features

The median duration of NDPH at the time of the initial consult with Dr. Evans was 0.7 years, and it was 1.9 years at the time of the last visit. Almost 33% of patients with the migraine phenotype had a history of episodic migraine compared with 16.2% with the tension-type phenotype. Headaches were side-locked unilateral in 8.5% (n = 28) of all patients, and 3.6% (n = 12) had a thunderclap onset.

The most common clinical features across all patients included noise sensitivity (72.1%), light sensitivity (71%), moderate pain at the time of initial consult (57.9%), pressure pain (54.9%), and throbbing pain (50.9%). Nausea was reported in 157 patients and vomiting was reported in 48 patients, all of whom were in the migraine phenotype group. Thunderclap onset was far more prevalent in the migraine phenotype group (11 patients) compared with the tension-type phenotype group (1 patient), as was vertigo (19 patients compared with 1) and visual aura (21 compared with 0).

The top precipitating factors across all patients included stressful life events (20.4%), an antecedent upper respiratory infection or flu-like illness (10.1%), and antecedent extracranial surgery (1.5%). Exacerbating or aggravating factors were far more prevalent in the migraine phenotype group compared with the tension-type phenotype group, with stress (14.6% vs. 5.9%), bright or flashing light (10.4% vs. 1.5%), loud noise (8.5% vs. 0%), and lack of sleep (6.5% vs. 4.4%) leading the way.

The months with the most onsets were June (8.5%), January (7.6%), and February (7.6%); there was no clear seasonal or cyclical variation. The most common prognostic type across all patients was persisting (refractory) at 93%, followed by remitting (self-limiting) at 4.3% and relapsing-remitting at 2.7%.
 

Unlocking a medical mystery

“This is the largest case review study ever published on NDPH, especially because most people think it’s a fairly rare disorder when it’s actually not,” Herbert G. Markley, MD, of the New England Regional Headache Center in Worcester, Mass., said in an interview.

“The thing people need to understand is that they may have a lot of these patients in their practice and not realize it,” he added. “They keep trying one medication after another, and the patients are giving up, and the doctors are giving up. It’s terrible. We don’t know what causes it, and we don’t know how to treat it. It’s one of the biggest mysteries left in medical science.”

“My idea about this condition, and this is shared by others, is that NDPH is not a diagnosis that describes a cohesive group of patients but rather a group of people who share certain features,” Morris Levin, MD, director of the Headache Center at the University of California, San Francisco, said in an interview. “And they would be better served if this diagnosis was split into different categories.”

While praising Dr. Evans and Dr. Turner for their categorization and classification work, Dr. Levin asked, “Let’s say you diagnose someone with NDPH; does that in any way help you with management of this person? The answer is no. Some might say, ‘If you put the patients in the migraine phenotype group, then you can use migraine treatments.’ My point would be: then call it migraine.

“I believe another way to approach NDPH might be to create subcategories of migraine and tension-type headaches,” he added. “A migraine that is either intermittent or nonexistent suddenly becomes daily. That could be a subcategory; rather than being called NDPH, call it ‘new persistent chronic migraine.’ Or ‘new persistent chronic tension-type headache.’ Perhaps that would serve us better in terms of grasping the underlying mechanisms and the best treatment for these patients.”

Along the same lines, Dr. Markley echoed Dr. Evans’ call for more prospective studies and more research on possible medication, hoping to fuel further understanding of this debilitating disorder.

“I think this will be a landmark study for people to look back on,” he said, “especially for anyone going into the headache specialty who has never heard of this type of headache and keeps wondering why they can’t help certain patients, no matter how many medications they try.”

The authors acknowledged their study’s limitations, including its single-center nature and the data abstraction process being performed by just one person. They added, however, that Dr. Evans is a “very experienced researcher with more than 30 years of experience in headache medicine who was abstracting his own patients, data that were very familiar to him.”

Dr. Evans and Dr. Turner declared no potential conflicts of interest.

Oral drug administration was significantly associated with a shorter length of stay for patients treated for headache in the emergency department setting, based on data from approximately 7,000 patients.

Headache is the fourth-most common chief complaint in the ED, accounting for approximately 3% of all ED visits, said Philip Wang, a medical student at the Cleveland Clinic, in a presentation at the annual meeting of the American College of Emergency Physicians.

A variety of pharmacotherapies are used to manage headache, which leads to a range of resource use, he said.

To understand the association between route of drug administration and length of ED stay, Mr. Wang and colleagues reviewed data from 7,233 visits by 6,715 patients at any of the 21 Cleveland Clinic Health System EDs in 2018 with headache as the primary discharge diagnosis. Patients admitted to the hospital were excluded; those treated with opioids, antiemetics, and/or NSAIDs were included. The average age of the study population was 31 years, 57% were White, and approximately half were Medicaid or Medicare patients.

Approximately 68% of patients received antiemetics, 66.8% received NSAIDs, and 9.8% received opioids. Approximately 42% of patients received parenteral-only treatment and 42% received oral-only treatment; 15% received mixed treatment. The average length of ED stay was 202 minutes.

In a multivariate analysis adjusted for sex, age, income, race, insurance status, ED type, and arrival time, treatment with oral drugs only was associated with an 11% reduction of length of stay, compared with treatment with parenteral medication only (P < .001). However, the length of stay for patients treated with mixed route of administration was 10% longer, compared with parenteral only (P < .001).

In terms of drug class (a secondary outcome), patients treated with opioids had a 10% increase in length of stay (P < .01) and those treated with antiemetics had a 14% increase in length of stay; however, patients treated with NSAIDs had a 7% decrease in length of stay.

The study findings were limited in part by the challenge of isolating patients presenting with a primary headache diagnosis, Mr. Wang noted in the presentation.

The challenge of controlling for all the potential factors impacting length of stay, which is “provider, resource, and situation dependent,” is an additional limitation, he said.

However, the results show that route of administration has a significant impact on length of ED stay in patients presenting with headache, he concluded.

The study received no outside funding. The researchers disclosed no relevant financial relationships.

Self-administered external trigeminal nerve stimulation (E-TNS) that is available over the counter is superior to sham stimulation in relieving pain for patients with episodic migraine, results from a phase 3 study show.

This is great news for headache patients who want to explore nondrug treatment options, said study investigator Deena E. Kuruvilla, MD, neurologist and headache specialist at the Westport Headache Institute, Connecticut.

She added that such devices “aren’t always part of the conversation when we’re discussing preventive and acute treatments with our patients. Making this a regular part of the conversation might be helpful to patients.”

The findings were presented at ANA 2021: 146th Annual Meeting of the American Neurological Association (ANA), which was held online.
 

A key therapeutic target

The randomized, double-blind trial compared E-TNS with sham stimulation for the acute treatment of migraine.

The E-TNS device (Verum Cefaly Abortive Program) stimulates the supraorbital nerve in the forehead. “This nerve is a branch of the trigeminal nerve, which is thought to be the key player in migraine pathophysiology,” Dr. Kuruvilla noted.

The device has been cleared by the U.S. Food and Drug Administration for acute and preventive treatment of migraine.

During a run-in period before randomization, patients were asked to keep a detailed headache diary and to become comfortable using the trial device to treat an acute migraine attack at home.

The study enrolled 538 adult patients at 10 centers. The patients were aged 18 to 65 years, and they had been having episodic migraines, with or without aura, for at least a year. The participants had to have received a migraine diagnosis before age 50, and they had to be experiencing an attack of migraine 2 to 8 days per month.

The patients used the device only for a migraine of at least moderate intensity that was accompanied by at least one migraine-associated symptom, such as photophobia, phonophobia, or nausea. They were asked not to take rescue medication prior to or during a therapy session.

Study participants applied either neurostimulation or sham stimulation for a continuous 2-hour period within 4 hours of a migraine attack over the 2-month study period.

The two primary endpoints were pain freedom and freedom from the most bothersome migraine-associated symptoms at 2 hours.

Compared to sham treatment, active stimulation was more effective in achieving pain freedom (P = .043) and freedom from the most bothersome migraine-associated symptom (P = .001) at 2 hours.

“So the study did meet both primary endpoints with statistical significance,” said Dr. Kuruvilla.

The five secondary endpoints included pain relief at 2 hours; absence of all migraine-associated symptoms at 2 hours; use of rescue medication within 24 hours; sustained pain freedom at 24 hours; and sustained pain relief at 24 hours.

All but one of these endpoints reached statistical significance, showing superiority for the active intervention. The only exception was in regard to use of rescue medication.

The most common adverse event (AE) was forehead paresthesia, discomfort, or burning, which was more common in the active-treatment group than in the sham-treatment group (P = .009). There were four cases of nausea or vomiting in the active-treatment group and none in the sham-treatment group. There were no serious AEs.
 

Available over the counter

Both moderators of the headache poster tour that featured this study – Justin C. McArthur, MBBS, from Johns Hopkins University, Baltimore, and Steven Galetta, MD, from NYU Grossman School of Medicine – praised the presentation.

Dr. Galetta questioned whether patients were receiving preventive therapies. Dr. Kuruvilla said that the patients were allowed to enter the trial while taking preventive therapies, including antiepileptic treatments, blood pressure medications, and antidepressants, but that they had to be receiving stable doses.

The investigators didn’t distinguish between participants who were taking preventive therapies and those who weren’t, she said. “The aim was really to look at acute treatment for migraine,” and patients taking such medication “had been stable on their regimen for a pretty prolonged period of time.”

Dr. McArthur asked about the origin of the nausea some patients experienced.

It was difficult to determine whether the nausea was an aspect of an individual patient’s migraine attack or was an effect of the stimulation, said Dr. Kuruvilla. She noted that some patients found the vibrating sensation from the device uncomfortable and that nausea could be associated with pain at the site.

The device costs $300 to $400 (U.S.) and is available over the counter.

Dr. Kuruvilla is a consultant for Cefaly, Neurolief, Theranica, Now What Media, and Kx Advisors. She is on the speakers bureau for AbbVie/Allergan, Amgen/Novartis, Lilly, the American Headache Society, Biohaven, and CME meeting, and she is on an advisory board at AbbVie/Allergan, Lilly, Theranica, and Amgen/Novartis. She is editor and associate editor of Healthline and is an author for WebMD/Medscape, Healthline.

New classes of antimigraine drugs demonstrate efficacy and improved tolerability for patients with chronic migraine, a new systematic review and meta-analysis finds.

“[T]he lack of cardiovascular risks of these new classes of migraine-specific treatments may provide alternative treatment options for individuals for whom currently available acute treatments have failed or for those with cardiovascular contraindications,” write lead author Chun-Pai Yang, MD, PhD, of Taichung (Taiwan) Veterans General Hospital and colleagues, in the paper, published online in JAMA Network Open.
 

Methods

The new study compared the outcomes for acute migraine management using the ditan, lasmiditan (a 5-hydroxytryptamine [5HT]1F–receptor agonist), and the two gepants, rimegepant, and ubrogepant (calcitonin gene–related peptide [CGRP] antagonists), with standard triptan (selective 5-HT1B/1D–receptor agonist) therapy.

The researchers evaluated 64 double-blind randomized clinical trials which included 46,442 patients, the majority of whom (74%-87%) were women with an age range of 36-43 years.

The primary outcome evaluated was the odds ratio for freedom from pain at 2 hours after a single dose and secondary outcomes were the OR for pain relief at 2 hours following a dose, as well as any adverse events.
 

Results

Dr. Yang and colleagues found that virtually all medications with widespread clinical use, regardless of class, were associated with higher ORs for pain freedom when compared with placebo.

Compared to ditan and gepant agents, however, triptans were associated with significantly higher ORs for pain freedom. The odds ratio ranges were 1.72-3.40 for lasmiditan, 1.58-3.13 for rimegepant, and 1.54-3.05 for ubrogepant.

With respect to pain relief at 2 hours, while all medications were more effective than placebo, triptans were associated with higher ORs when compared with the other drug classes: lasmiditan (range: OR, 1.46; 95% confidence interval, 1.09-1.96 to OR, 3.31; 95% CI, 2.41-4.55), rimegepant (range: OR, 1.33; 95% CI, 1.01-1.76 to OR, 3.01; 95% CI, 2.33-3.88), and ubrogepant (range: OR, 1.38; 95% CI, 1.02-1.88 to OR, 3.13; 95% CI, 2.35-4.15)

When assessing tolerability, the researchers found that overall, triptans were associated with the higher ORs for any adverse events (AE) with a trend of dose-response relationship. Lasmiditan (in the ditan class) was associated with the highest risk for AEs among all treatments. Most of the AEs were mild to moderate and included chest pain, tightness, heaviness, and pressure.

Dr. Yang and colleagues note that, “although these two new classes of antimigraine drugs may not be as efficacious as triptans, these novel abortive agents without cardiovascular risks might offer an alternative to current specific migraine treatments for patients at risk of cardiovascular disease.”
 

Balancing efficacy and tolerability

“When choosing an acute medication for a patient there is always a balance between efficacy and tolerability,” headache specialist and associate director of North Shore Headache and Spine Lauren Natbony, MD, said in an interview.

“A medication can only be effective if a patient is able to tolerate it and will actually use it,” Dr. Natbony said.

With respect to the current review, Dr. Natbony pointed out, “response to acute therapy can differ between migraine attacks and may be based on variables not controlled for, such as how early in an attack the medication was taken, associated symptoms such as nausea that may make oral medications less efficacious, etc.”

The authors acknowledge that the focus on short-term responses and AEs after a single dose is a limitation of the study. They also pointed out what they considered to be a strength of the study, which was its network meta-analysis design. According to the authors, this design allowed for “multiple direct and indirect comparisons, ranking the efficacy and safety of individual pharmacologic interventions and providing more precise estimates than those of RCTs and traditional meta-analysis.”

Funding for this study was provided through grants from the Ministry of Science and Technology, Taiwan; the Brain Research Center; and National Yang Ming Chiao Tung University.

Dr. Yang has received personal fees and grants from various pharmaceutical companies. He has also received grants from the Taiwan Ministry of Technology and Science, the Brain Research Center, National Yang Ming Chiao Tung University, and Taipei Veterans General Hospital outside the submitted work. The other authors and Dr. Natbony disclosed no relevant financial relationships.

With respect to pain relief at 2 hours, while all medications were more effective than placebo, triptans were associated with higher ORs when compared with the other drug classes: lasmiditan (range: OR, 1.46; 95% confidence interval, 1.09-1.96 to OR, 3.31; 95% CI, 2.41-4.55), rimegepant (range: OR, 1.33; 95% CI, 1.01-1.76 to OR, 3.01; 95% CI, 2.33-3.88), and ubrogepant (range: OR, 1.38; 95% CI, 1.02-1.88 to OR, 3.13; 95% CI, 2.35-4.15)

When assessing tolerability, the researchers found that overall, triptans were associated with the higher ORs for any adverse events (AE) with a trend of dose-response relationship. Lasmiditan (in the ditan class) was associated with the highest risk for AEs among all treatments. Most of the AEs were mild to moderate and included chest pain, tightness, heaviness, and pressure.

Dr. Yang and colleagues note that, “although these two new classes of antimigraine drugs may not be as efficacious as triptans, these novel abortive agents without cardiovascular risks might offer an alternative to current specific migraine treatments for patients at risk of cardiovascular disease.”
 

Balancing efficacy and tolerability

“When choosing an acute medication for a patient there is always a balance between efficacy and tolerability,” headache specialist and associate director of North Shore Headache and Spine Lauren Natbony, MD, said in an interview.

“A medication can only be effective if a patient is able to tolerate it and will actually use it,” Dr. Natbony said.

With respect to the current review, Dr. Natbony pointed out, “response to acute therapy can differ between migraine attacks and may be based on variables not controlled for, such as how early in an attack the medication was taken, associated symptoms such as nausea that may make oral medications less efficacious, etc.”

The authors acknowledge that the focus on short-term responses and AEs after a single dose is a limitation of the study. They also pointed out what they considered to be a strength of the study, which was its network meta-analysis design. According to the authors, this design allowed for “multiple direct and indirect comparisons, ranking the efficacy and safety of individual pharmacologic interventions and providing more precise estimates than those of RCTs and traditional meta-analysis.”

Funding for this study was provided through grants from the Ministry of Science and Technology, Taiwan; the Brain Research Center; and National Yang Ming Chiao Tung University.

Dr. Yang has received personal fees and grants from various pharmaceutical companies. He has also received grants from the Taiwan Ministry of Technology and Science, the Brain Research Center, National Yang Ming Chiao Tung University, and Taipei Veterans General Hospital outside the submitted work. The other authors and Dr. Natbony disclosed no relevant financial relationships.

Many pediatric patients with headache experienced increased headache frequency, increased anxiety, and worsening mood through the first year of the COVID-19 pandemic, a newly released survey finds. But some actually found the pandemic era to be less stressful since they were tightly wound and could more easily control their home environments, a researcher said.

“We need to be very mindful of the connections between school and home environments – and social situations – and how they impact headache frequency,” said Marc DiSabella, DO, a pediatric neurologist at Children’s National Hospital/George Washington University, Washington. He is coauthor of a poster presented at the 50th annual meeting of the Child Neurology Society.

Dr. DiSabella and colleagues launched the survey to understand what headache patients were experiencing during the pandemic. They expected that “things were going to go really terrible in terms of headaches – or things would go great, and then things would crash when we had to reintegrate into society,” he said in an interview.

The team surveyed 113 pediatric patients who were evaluated at the hospital’s headache clinic between summer 2020 and winter 2021. Most of the patients were female (60%) and were aged 12-17 years (63%). Twenty-one percent were younger than 12 and 16% were older than 17. Chronic migraine (37%) was the most common diagnosis, followed by migraine with aura (22%), migraine without aura (19%), and new daily persistent headache (15%).

Nearly half (46%) of patients said their headaches had worsened during the pandemic. Many also reported more anxiety (55%), worsened mood (48%) and more stress (55%).

Dr. DiSabella said it’s especially notable that nearly two-thirds of those surveyed reported they were exercising less during the pandemic. Research has suggested that exercise and proper diet/sleep are crucial to improving headaches in kids, he said, and the survey findings suggest that exercise may be especially important. “Engaging in physical activity changes their pain threshold,” he said.

The researchers also reported that 60% of those surveyed said they looked at screens more than 6 hours per day. According to Dr. DiSabella, high screen use may not be worrisome from a headache perspective. “We have another study in publication that shows there’s not a clear association between frequency of screen use and headache intensity,” he said.

The survey doesn’t examine what has happened in recent weeks as schools have reopened. Anecdotally, Dr. DiSabella said some patients with migraine are feeling the stress of returning to normal routines. “They tend to be type A perfectionists and do well when they’re in control of their environment,” he said. “Now they’ve lost the control they had at home and are being put back into a stressful environment.”
 

Pandemic effects mixed

Commenting on the study, child neurologist Andrew D. Hershey, MD, PhD, of Cincinnati Children’s Hospital Medical Center, questioned the finding that many children suffered from more headaches during the pandemic. In his experience, “headaches were overall better when [children] were doing virtual learning,” he said in an interview. “We had fewer admissions, ED visits declined, and patients were maintaining better healthy habits. Some did express anxiety about not seeing friends, but were accommodating by doing this remotely.”

He added: “Since their return, kids are back to the same sleep deprivation issue since schools start too early, and they have more difficulty treating headaches acutely since they have to go to the nurse’s office [to do so]. They self-report a higher degree of stress and anxiety.”

On the other hand, Jack Gladstein, MD, a child neurologist at the University of Maryland, Baltimore, said in an interview that most of his patients suffered more headaches during the pandemic, although a small number with social anxiety thrived because they got to stay at home.

He agreed with Dr. DiSabella about the value of exercise. “At every visit we remind our youngsters with migraine to eat breakfast, exercise, get regular sleep, and drink fluids,” he said.

No study funding was reported. The study authors, Dr. Hershey, and Dr. Gladstein reported no disclosures.

Women with a history of migraine are more likely to experience severe or very severe hot flashes than women without migraines, according to research presented Sept. 24 at the hybrid annual meeting of the North American Menopause Society. An estimated one in five women experience migraine, and women tend to have greater migraine symptoms and disability, the authors note in their background information. Since migraines are also linked to a higher risk of cardiovascular disease, the authors sought to learn whether migraines were associated with vasomotor symptoms, another cardiovascular risk factor.

“The question in my mind is, can we do better at predicting cardiovascular risk in women because the risk prediction models that we have really don’t work all that well in women because they were designed for use in men,” Stephanie S. Faubion, MD, MBA, Penny and Bill George Director for Mayo Clinic’s Center for Women’s Health said in an interview. “My ultimate goal is to see if we can somehow use big data, artificial intelligence to figure out how to weight some of these female-specific or female-predominant factors to come up with a better model for cardiovascular risk prediction.”

The researchers analyzed cross-sectional data from 3,308 women who participated in the Data Registry on the Experiences of Aging, Menopause and Sexuality (DREAMS) study through Mayo Clinic sites in Rochester, Minn.; Scottsdale, Ariz.; and Jacksonville, Fla.. The women ranged in age from 45 to 60 years old, with an average age of 53, and the vast majority of them were white (95%) and had at least some college (93%). Most were also in a long-term relationship (85%), and a majority were employed (69%) and postmenopausal (67%).

The data, collected between May 2015 and December 2019, included a self-reported history of migraine and questionnaires that included the Menopause Rating Scale of menopause-related symptoms.

The researchers adjusted their findings to account for body mass index (BMI), menopause status, smoking status, depression, anxiety, current use of hormone therapy, and presence of low back pain within the past year. ”The diagnosis of low back pain, another pain disorder, was used to test the specificity of the association of migraine and vasomotor symptoms,” the authors write.

Just over a quarter of the women (27%) reported a history of migraine, and these women’s Menopause Rating Scale scores were an average 1.36 points greater than women without a history of migraines (P < .001). Women with self-reported migraine were also 40% more likely than women without migraines to report severe or very severe flashes versus reporting no hot flashes at all (odds ratio, 1.4; P = .02).

“The odds of reporting more severe hot flashes increased monotonically in women with a history of migraine,” the authors report. “In addition, women with low back pain had higher Menopause Rating Scale scores, but were no more likely to have severe/very severe hot flashes than those without back pain, confirming the specificity of the link between vasomotor symptoms and migraine.”

It’s not clear if migraine or hot flashes are risk factors that add to a woman’s existing cardiovascular risk profile or whether they are simply biomarkers of a shared pathway, Dr Faubion said in an interview. She speculates that the common link between migraine and vasomotor symptoms could be neurovascular dysregulation.

Rachael B. Smith, DO, of the department of ob.gyn. at the University of Arizona, Phoenix, was not involved in the research but found that hypothesis plausible as well.

“Our neurologic and vascular systems are coordinated physiologic processes working together for basic brain and body function,” Dr. Smith said in an interview. Some of the symptoms of migraines and menopause are similar and both are often explained by the dysfunction of these systems. The association between history of migraines and severity of vasomotor symptoms is very likely to be explained by this dysregulation between the neurologic and vascular systems.”

Dr. Smith also pointed out, however, that the largely homogeneous study population, all from the same national clinic system, makes it difficult to know how generalizable these findings are.

The primary clinical implications of these findings are that women’s providers need to be sure they’re asking their patients about migraine history and symptoms.

“The counseling we provide on menopausal symptoms should be better tailored to our patients’ medical history, specifically inquiring about history of migraines and how this may impact their symptoms,” Dr. Smith said.
