Atogepant is the first drug from this novel class to undergo efficacy testing in an advanced-phase trial for prevention of migraine headaches, David W. Dodick, MD, said at the annual meeting of the American Headache Society. Two other agents from the gepant class, rimegepant and ubrogepant, have undergone phase 3 testing for acute treatment of migraine headache, and both drugs are now under Food and Drug Administration consideration for an acute-treatment indication.

Three monoclonal antibodies to the calcitonin gene–related peptide (CGRP) receptor have received FDA marketing approval since 2018 for migraine headache prevention. The small-molecule antagonists to the CGRP receptor in the gepant class have an effect similar to the monoclonal antibodies, but with different dosage schedules, an oral route of administration, and with half-lives measured in hours, compared with days and weeks.

“Historically the [gepant] class of drugs was designed for acute treatment, and a couple of drugs from this class didn’t make it because of liver toxicity, but the liver toxicity is not a class effect.” The more recent candidate agents – atogepant, ubrogepant, and rimegepant – have shown hepatic safety as well as overall safety, noted Dr. Dodick, a neurologist and headache specialist at the Mayo Clinic in Phoenix.

If these gepant agents eventually receive FDA approval, which seems likely based on the evidence collected so far, they would collectively form “the only class to have both acute and preventive indications” for migraine, Dr. Dodick said in an interview. The preventive efficacy seen with atogepant in the current study is likely a class effect that has not yet been tested in ubrogepant and rimegepant.

In the multicenter study he reported, 834 patients, 86% of them women, were randomized to placebo or to any of five dosages of atogepant, ranging from 10 mg once daily to 60 mg b.i.d. Study participants had a history of episodic migraine with an average of nearly eight migraine-headache days per month and an average disease duration of about 19 years. The patients’ average age was about 40 years, and 72% had never before used a migraine-preventive treatment. Half had migraine without aura, about a quarter had migraine with aura, and a quarter had migraines of both types.


The researchers had safety data for 825 patients, and efficacy data for 795.

The study’s primary efficacy endpoint was the reduction from baseline in average migraine headache days per month after 12 weeks on treatment. Average migraine headache days fell by 2.85 days in the placebo group and by 3.55-4.23 days in the atogepant treatment groups, a significant difference. The reduction depended on the dosage patients received, but there was no clear dose-response relationship.

At least a 50% drop in average monthly headache day totals was seen in 40% of the placebo patients and in 52%-62% of the patients on atogepant, depending on their dosage. In this case, a signal appeared for a dose-response relationship as only the two subgroups with the patients who received the largest atogepant dosages showed statistically significant improvements in response, compared with placebo.

All patients on atogepant, regardless of their dosage, also had statistically significant reductions in their use of acute migraine medications, compared with placebo patients.

The level of benefit beyond placebo seen in these results was “clinically meaningful,” and roughly comparable with the preventive benefit seen with both the CGRP receptor antagonist monoclonal antibodies, as well as with the three conventional agents most commonly used for migraine headache prevention in current U.S. practice: topiramate, amitriptyline, and propranolol, Dr. Dodick said. Amitriptyline is not approved for this indication.

The adverse event profile among patients who received atogepant was about the same as it was among the placebo recipients. Seven study patients had serious treatment-related adverse effects; two of these patients were in the placebo arm of 186 patients. The most common adverse events were nausea, constipation, and fatigue, and were seen mostly at the highest dosage of atogepant. The incidence of elevated liver enzymes was low and similar in the placebo and drug-treated patients. Two patients, one on placebo and one on atogepant, had their liver enzymes reach at least five times the upper limit of normal. None had their enzymes reach at least 10 times the upper limit of normal, and no patients in the study had a response that fulfilled “Hy’s law,” which flags drug-induced liver injury as patients who develop the combination of elevated liver enzymes, elevated bilirubin, and depressed alkaline phosphatase.

The study was sponsored by Allergan, the company developing atogepant and ubrogepant. Dr. Dodick has been a consultant to Allergan and to several other drug companies.

PHILADELPHIA – People with moderately high levels of riboflavin consumption from food – two to three times the recommended dietary allowance – had a significantly lower prevalence of a recent severe or migraine headache in a study of more than 3,600 younger U.S. adults.

Adults 20-50 years old who consumed 2.07-2.87 mg riboflavin (vitamin B₂) in food a day based on a 24-hour recall questionnaire had an adjusted, statistically significant 27% reduced prevalence of a recent severe or migraine headache, compared with people in the lowest quartile of dietary riboflavin intake, 1.45 mg/day or less, Margaret Slavin, Ph.D., said at the annual meeting of the American Headache Society. Foods particularly high in riboflavin include eggs, milk, and meat.

Dietary riboflavin intakes greater than 2.87 mg/day were not linked to a difference in the prevalence of a recent history of severe or migraine headache, compared with lowest-quartile consumption. Additionally, riboflavin intake from supplements alone at any level of consumption also showed no statistically significant link with the prevalence of a recent, severe headache, said Dr. Slavin, a nutrition and food studies researcher at George Mason University in Fairfax, Va.

The “vast majority” of people in the study had a riboflavin intake that at least matched the U.S. recommended dietary allowance (RDA),1.3 mg/ day for men and 1.1 mg/day for women), “but it’s possible that people with migraine headaches need more riboflavin,” Dr. Slavin suggested. Professional societies in the United States (Neurology. 2012 Apr;78[17]: 1346-53) and Canada (Can J Neurol Sci. 2012 Mar;39[Suppl 2]S8-S28) have gone on record with some level of recommendation for a daily riboflavin supplement of 400 mg to prevent migraine headaches, she said.

A U.S. guideline that included riboflavin has been “retired” because of an issue unrelated to riboflavin, according to the Neurology website.

The new study ran data collected in the biennial National Health and Nutrition Examination Survey (NHANES), specifically the surveys from 2001-2002 and 2003-2004. The combined data included 5,528 adults 20-50 years old, and 3,634 with complete data and without an excluding condition such as pregnancy, diabetes, or menopause. Among the study participants 884 reported having “severe headaches or migraines,” during the 3 months preceding the survey and the remaining 2,750 people served as controls. People who reported recent severe headache or migraine overall had a significantly lower average amount of vitamin B2 in their diet than did the controls, but the two subgroups showed no significant differences in their levels of riboflavin intake from supplements, or from both diet and supplements combined.

The researchers calculated odds ratios for people having severe headaches or migraines relative to their riboflavin-intake quartile, and they adjusted the findings for age, sex, body mass index, and alcohol intake.

Further analysis that looked at total riboflavin intake, from both food and supplements, showed that the two middle quartiles for this metric, with a combined riboflavin intake of 1.6-3.8 mg/day, had a significantly reduced prevalence of recent severe or migraine headaches, compared with the lowest-intake quartile, with an odds ratio that roughly matched the dietary riboflavin analysis.

PHILADELPHIA – Nearly one-fifth of U.S. residents who self-reported symptoms consistent with a diagnosis of migraine also self-reported drug use for their migraine attacks that constituted medication overuse, according to findings from an analysis of 16,789 people with migraine.

Mitchel L. Zoler/MDedge News

About 18% of the people identified with migraine in the study cohort reported a drug consumption pattern that met the prespecified definition of “medication overuse,” Todd J. Schwedt, MD, and his associates reported in a poster at the annual meeting of the American Headache Society. Supplying each migraine patient with a “comprehensive treatment plan” along with “improved acute treatment options ... may help reduce the prevalence and associated burden of medication overuse,” said Dr. Schwedt, a professor of neurology at the Mayo Clinic in Phoenix. The analysis also showed that medication overuse (MO) significantly linked with several markers of worse clinical status.

If patients have “an effective preventive treatment that reduces headaches and migraine attacks then they will, in general, use less acute medications. Many people with migraine never even get diagnosed, and patients who qualify for preventive treatment never get it,” Dr. Schwedt noted in an interview. He described a comprehensive treatment plan as a management strategy that includes lifestyle modifications, a migraine-prevention agent, and the availability of an effective acute treatment for a patient to use when a migraine strikes along with clear instructions on how to appropriately self-administer the medication. Only a small fraction of U.S. migraine patients currently receive this complete package of care, he said.

The analysis he ran used data collected in the CaMEO (Chronic Migraine Epidemiology and Outcomes) study, which used an Internet-based survey to collect data from a representative 58,000-person sample of U.S. residents, which included 16,789 who met the applied migraine definition, with 91% having fewer than 15 headaches/month and the remaining 9% with a monthly headache average of 15 or more (Cephalagia. 2015 Jun;35[7]:563-78).

The researchers defined overuse of a single medication as use 15 times or more a month of an NSAID, aspirin, or acetaminophen, or use at least 10 times a month of a triptan, ergotamine, or opioid. They also had a prespecified definition of multidrug overuse that applied similar monthly thresholds. The patients averaged about 41 years old, three-quarters were women, and 85% were white. Patients identified with MO had a substantially higher rate of headaches per month: an average of nearly 12, compared with an average of about 4 per month among those without overuse. Almost two-thirds of the patients with MO reported having been formally diagnosed as having migraine headaches, compared with 41% of those without overuse.

Among the 13,749 patients (82%) on some headache medication, 67% were on a nonopioid analgesic, including 61% on an NSAID. MO among all people on nonopioid analgesics was 16%, and 12% among those who used NSAIDS. The most overused drug in this subgroup were combination analgesics, overused by 18% of those taking these drugs.

The drug class with the biggest MO rate was opioids, used by 12% of those on any medication and overused by 22% of those taking an opioid. Triptans were taken by 11%, with an MO rate of 11% among these users. Ergotamine was used by less than 1% of all patients, and those taking this drug tallied a 19% MO rate.

“Opioids were the class most often overused, more evidence that opioids should rarely if ever be used to treat migraine,” Dr. Schwedt said.

The analysis also showed that patients who had MO has multiple signs of worse clinical status. Patients with MO had a significantly higher rate of diagnosed depression, 54%, compared with 28% in those without MO; anxiety, 49% compared with 26%; migraine-associated disability, 73% compared with 32%; migraine-associated functional impairment (Migraine Interictal Burden Scale), 65% compared with 32%; and emergency department or urgent care use, 13% compared with 3%. All these between-group differences were statistically significant.

CaMEO was funded by Allergan. Dr. Schwedt has been a consultant to Allergan, and also to Alder, Amgen, Cipla, Dr. Reddy’s, Ipsen, Lilly, Novartis, and Teva. He has stock ownership in Aural Analytics, Nocira, and Second Opinion, and he has received research funding from Amgen.

PHILADELPHIA – Nearly one-fifth of U.S. residents who self-reported symptoms consistent with a diagnosis of migraine also self-reported drug use for their migraine attacks that constituted medication overuse, according to findings from an analysis of 16,789 people with migraine.

About 18% of the people identified with migraine in the study cohort reported a drug consumption pattern that met the prespecified definition of “medication overuse,” Todd J. Schwedt, MD, and his associates reported in a poster at the annual meeting of the American Headache Society. Supplying each migraine patient with a “comprehensive treatment plan” along with “improved acute treatment options ... may help reduce the prevalence and associated burden of medication overuse,” said Dr. Schwedt, a professor of neurology at the Mayo Clinic in Phoenix. The analysis also showed that medication overuse (MO) significantly linked with several markers of worse clinical status.

If patients have “an effective preventive treatment that reduces headaches and migraine attacks then they will, in general, use less acute medications. Many people with migraine never even get diagnosed, and patients who qualify for preventive treatment never get it,” Dr. Schwedt noted in an interview. He described a comprehensive treatment plan as a management strategy that includes lifestyle modifications, a migraine-prevention agent, and the availability of an effective acute treatment for a patient to use when a migraine strikes along with clear instructions on how to appropriately self-administer the medication. Only a small fraction of U.S. migraine patients currently receive this complete package of care, he said.

The analysis he ran used data collected in the CaMEO (Chronic Migraine Epidemiology and Outcomes) study, which used an Internet-based survey to collect data from a representative 58,000-person sample of U.S. residents, which included 16,789 who met the applied migraine definition, with 91% having fewer than 15 headaches/month and the remaining 9% with a monthly headache average of 15 or more (Cephalagia. 2015 Jun;35[7]:563-78).

The researchers defined overuse of a single medication as use 15 times or more a month of an NSAID, aspirin, or acetaminophen, or use at least 10 times a month of a triptan, ergotamine, or opioid. They also had a prespecified definition of multidrug overuse that applied similar monthly thresholds. The patients averaged about 41 years old, three-quarters were women, and 85% were white. Patients identified with MO had a substantially higher rate of headaches per month: an average of nearly 12, compared with an average of about 4 per month among those without overuse. Almost two-thirds of the patients with MO reported having been formally diagnosed as having migraine headaches, compared with 41% of those without overuse.

Among the 13,749 patients (82%) on some headache medication, 67% were on a nonopioid analgesic, including 61% on an NSAID. MO among all people on nonopioid analgesics was 16%, and 12% among those who used NSAIDS. The most overused drug in this subgroup were combination analgesics, overused by 18% of those taking these drugs.

The drug class with the biggest MO rate was opioids, used by 12% of those on any medication and overused by 22% of those taking an opioid. Triptans were taken by 11%, with an MO rate of 11% among these users. Ergotamine was used by less than 1% of all patients, and those taking this drug tallied a 19% MO rate.

“Opioids were the class most often overused, more evidence that opioids should rarely if ever be used to treat migraine,” Dr. Schwedt said.

The analysis also showed that patients who had MO has multiple signs of worse clinical status. Patients with MO had a significantly higher rate of diagnosed depression, 54%, compared with 28% in those without MO; anxiety, 49% compared with 26%; migraine-associated disability, 73% compared with 32%; migraine-associated functional impairment (Migraine Interictal Burden Scale), 65% compared with 32%; and emergency department or urgent care use, 13% compared with 3%.

PHILADELPHIA – Nineteen percent of patients with migraine use opioids to treat migraine, according to a survey of more than 21,000 patients in 2018. People with 4 or more migraine headache days per month are more likely to use opioids, compared with people with fewer migraine headache days per month, researchers said. Opioid use for migraine “remains alarmingly high,” the investigators said at the annual meeting of the American Headache Society.

Although opioid use for the treatment of migraine typically is discouraged, studies indicate that it is common. Evidence suggests that opioids may increase the risk of progression from episodic to chronic migraine.

To evaluate opioid use in people with migraine, Sait Ashina, MD, of Harvard Medical School and Beth Israel Deaconess Medical Center in Boston, and the research colleagues analyzed data from 21,143 people with migraine who participated in the OVERCOME (Observational Survey of the Epidemiology, Treatment and Care of Migraine), a Web-based study of a representative U.S. sample. OVERCOME enrolled participants in the fall of 2018.

The researchers classified self-reported opioid use for migraine as current use in the past 12 months, former use, or never. Participants had a mean age of 42 years, and 74% were female. The researchers used a multivariable logistic regression model adjusted for age and sex in their analyses.

“Strikingly, we were able to find 19% of people with migraine were reporting current use of opioids,” Dr. Ashina said.

Among 12,299 patients with 0-3 migraine headache days per month, 59% were never, 26% former, and 15% current users of opioids for migraine. Among 8,844 patients with 4 or more migraine headache days per month, 44.9% were never, 31.2% former, and 23.9% current users of opioids for migraine.

There was an increased likelihood of opioid use for migraine in people with pain comorbidities such as back pain, neck pain, and fibromyalgia and in people with anxiety and depression.

Approximately 30%-40% of those who used opioids for migraine were using strong opioids, as defined by the World Health Organization, Dr. Ashina noted. Preliminary analyses indicate that patients tended to receive opioids in a primary care setting, he said.

Eli Lilly funded the OVERCOME study. Dr. Ashina has consulted for Novartis, Amgen, Promius, Supernus, Satsuma, and Allergan. He is on the Editorial Advisory Board for Neurology Reviews.

PHILADELPHIA – A majority of migraineurs with 4 or more headache days per month have seen a health care professional for headache in the preceding 12 months, according to an investigation presented at the annual meeting of the American Headache Society.

The largest group of these patients consults primary care physicians. The acute and preventive migraine treatment that these patients receive vary according to the type of provider that they see. Nevertheless, treatment is generally suboptimal, compared with the standards of current guidelines, said the investigators.

Bruce Jancin/MDedge News

Migraine is underdiagnosed and undertreated, said Dawn C. Buse, PhD, clinical professor of neurology at Albert Einstein College of Medicine, New York, and colleagues. Recent changes in health care policy and the expanded array of treatments for migraine warrant an investigation of the current state of migraine care, they added. They examined survey data to understand where patients with migraine in the United States seek care, which characteristics are associated with seeking care in the previous 12 months, and which treatments are prescribed.

Dr. Buse and colleagues analyzed data from the OVERCOME (Observational Survey of the Epidemiology, Treatment, and Care of Migraine) study. These data were obtained in 2018 using a Web-based survey of a representative U.S. sample of 21,143 patients with migraine. The investigators focused on care seeking and medication use in a subsample of 8,844 patients with 4 or more migraine headache days per month to better understand those with the greatest care needs.

The mean age of this subsample was 42.0 years. Approximately 78% of participants were female, and 74.8% were white. In the preceding 12 months, 61.1% of the patients sought care for migraine; 38.3% sought care from more than two types of provider. Provider types included primary care physicians (45.5%), neurologists (20.2%), emergency medicine clinicians (19.2%), urgent care providers (14.4%), pain specialists (12.8%), headache specialists (12.0%), and retail (nonurgent) clinics (10.4%).

Dr. Buse and colleagues found that sociodemographic factors such as age, sex, education, income, and health insurance type influenced participants’ likelihood of seeking care. Seeking care was positively associated with the number of headache days, pain severity, allodynia, aura, and prodrome. When the researchers examined migraine characteristics, they found that nausea and vomiting (68.8%) was more likely to prompt a patient to seek care, compared with phonophobia and photophobia (64.3%). Participants who sought care from a headache specialist (55.0%) or a neurologist (50.1%) were most likely to be using migraine preventive medication. More than 20% of migraineurs seeking care from primary care, urgent care, or retail clinic professionals were undiagnosed.

Primary care doctors were most likely to prescribe triptans, followed by opioids and preventive medications. Neurologists and headache specialists were most likely to prescribe preventive medications and unlikely to prescribe opioids.

Eli Lilly funds the OVERCOME study. Dr. Buse consults for Lilly on this study, but she and her coauthors who do not work in the industry did not receive any funding for any work related to writing, publishing, or presenting any abstracts, posters, platforms, or manuscripts.

Periodontal inflammation is associated with increased circulating levels of calcitonin gene-related peptide (CGRP) in patients with chronic migraine, a new study found. The cohort included 102 chronic migraineurs and 77 age- and sex-matched individuals free of headache/migraine. Full-mouth periodontal parameters were recorded and the periodontal inflamed surface area (PISA) was calculated to quantify the periodontal inflammatory status for each participant. Researchers found:

• In the chronic migraine group, patients with periodontitis had greater levels of serum CGRP and IL-6, while nonsignificant differences were observed with IL-10 concentrations vs those without periodontitis.
• PISA was independently associated with CGRP in patients with chronic migraine.

Individuals with migraine demonstrated a different dry eye (DE) symptom, yet a similar DE sign profile when compared with those without migraine, a new study found. The prospective cross-sectional study of individuals with DE symptoms evaluated symptoms and signs of DE, including symptoms suggestive of nerve dysfunction. Among the details:

• Of 250 individuals, 31 met International Classification of Headache Disorders criteria for migraine based on a validated screen.
• Those with migraine were significantly younger and more likely to be female vs controls.
• Individuals with migraine had more severe DE symptoms and ocular pain vs controls.
• DE symptoms in those with migraine may be driven by nerve dysfunction as opposed to ocular surface abnormalities.

Atypical Interactions of Cortical Networks in Chronic Migraine

The severity of headache is associated with opposite connectivity patterns in frontal executive and dorsal attentional networks in patients with chronic migraine, a new study found. Twenty patients with chronic migraine (CM) without preventive therapy, or acute medication overuse underwent 3T MRI scans and were compared to a group of 20 healthy controls (HC). Researchers used MRI to collect resting-state data in 3 selected networks, identified using group independent component analysis (ICA): the default mode network (DMN), the executive control network (ECN), and the dorsal attention system (DAS). They found:

• Compared to HC, patients with CM had significantly reduced functional connectivity between the DMN and the ECN.
• The DAS showed significantly stronger functional connectivity (FC) with the DMN and weaker FC with the ECN.
• The higher the severity of the headache, the increased strength of DAD connectivity, and the lower the strength of the ECN connectivity.

PHILADELPHIA – The level of exposure to white light is associated with acute risk of headache onset in patients with episodic migraine, according to research presented at the annual meeting of the American Headache Society. The data raise the question of whether modifying light exposure could reduce headache frequency in this population, said Suzanne M. Bertisch, MD, MPH, a physician and clinical investigator in the division of sleep and circadian disorders at Brigham and Women’s Hospital in Boston.

About 40% of patients with migraine identify light as a trigger. Most studies that have examined the association between light and migraine onset have been retrospective and have relied on subjective measures of light exposure.

From March 2016 to August 2017, Dr. Bertisch and colleagues enrolled 101 adults with episodic migraine into a prospective cohort study. For 79 of these participants, light exposure was measured continuously for 6 weeks by actigraph. In the morning and evening, participants recorded data such as headache onset, duration, and intensity in electronic headache diaries. They also recorded data about covariates such as caffeine intake, alcohol intake, sleep, and stress.

Dr. Bertisch and colleagues divided the day into four 6-hour periods and calculated mean light exposure within each period. After researchers adjusted for covariates, they found that higher mean photopic illuminance was associated with a 12% higher risk of headache during the same period. Mean photopic illuminance was not associated with headache onset in the next period, however.

Dr. Bertisch had no disclosures relevant to this study.

They also recorded data about covariates such as caffeine intake, alcohol intake, sleep, and stress.

Dr. Bertisch and colleagues divided the day into four 6-hour periods and calculated mean light exposure within each period. After researchers adjusted for covariates, they found that higher mean photopic illuminance was associated with a 12% higher risk of headache during the same period. Mean photopic illuminance was not associated with headache onset in the next period, however.

PHILADELPHIA – The level of exposure to white light is associated with acute risk of headache onset in patients with episodic migraine, according to research presented at the annual meeting of the American Headache Society. The data raise the question of whether modifying light exposure could reduce headache frequency in this population, said Suzanne M. Bertisch, MD, MPH, a physician and clinical investigator in the division of sleep and circadian disorders at Brigham and Women’s Hospital in Boston.

About 40% of patients with migraine identify light as a trigger. Most studies that have examined the association between light and migraine onset have been retrospective and have relied on subjective measures of light exposure.

From March 2016 to August 2017, Dr. Bertisch and colleagues enrolled 101 adults with episodic migraine into a prospective cohort study. For 79 of these participants, light exposure was measured continuously for 6 weeks by actigraph. In the morning and evening, participants recorded data such as headache onset, duration, and intensity in electronic headache diaries. They also recorded data about covariates such as caffeine intake, alcohol intake, sleep, and stress.

Dr. Bertisch and colleagues divided the day into four 6-hour periods and calculated mean light exposure within each period. After researchers adjusted for covariates, they found that higher mean photopic illuminance was associated with a 12% higher risk of headache during the same period. Mean photopic illuminance was not associated with headache onset in the next period, however.

PHILADELPHIA – A surprisingly large number of patients with migraine who first seek care for migraine in a primary care setting receive an initial migraine diagnosis from a neurologist, said Alice R. Pressman, PhD at the annual meeting of the American Headache Society.

Dr. Pressman, executive director of research, development, and dissemination for Sutter Health, and her research colleagues analyzed data from primary care patients who sought care for migraine in the Sutter Health healthcare network in Northern California. They found that women were 10% more likely than men to consult a neurologist and that Asian patients had a longer time to a first neurology encounter for migraine, compared with Caucasian patients.

“Those who sought care from neurology had more severe migraine symptomology, disability, and comorbidities,” the researchers reported. Furthermore, patients with migraine seen by neurologists were more likely to receive prescriptions for acute and preventive migraine medications, compared with patients only seen by primary care physicians.

The study, known as the Migraine Signature Study, used electronic health records (EHR) and patient-reported questionnaire data to examine the clinical experiences and care of patients with migraine.

The primary care population consisted of 1.4 million adults with at least one office visit to primary care in 2013-2017. Using the validated Migraine Probability Algorithm, the researchers identified approximately 94,000 patients who sought care for migraine.

The investigators also invited 38,536 patients to complete an online survey about migraine criteria, symptomology, health resource utilization, and patient-reported outcomes such as disability, acute treatment optimization, cutaneous allodynia, depression, anxiety, and posttraumatic stress disorder (PTSD).

Of the patients who sought care for migraine, 72,624 patients did not receive migraine care from neurology, and 21,525 did.

Patients with migraine care from a neurologist were more likely to have at least one acute migraine medication order (89.4% vs. 80.6%), at least one preventive migraine medication order (78.6% vs. 49.1%), and any migraine medication order (95.3% vs. 85.9%). In addition, those with at least one medication order in the primary care setting had fewer orders per person per year, compared with those with at least one medication order in the neurology setting (1.1 vs. 1.6).

About one-third of the patients who sought care for migraine had no migraine encounters in the first 12 months of the study. Of the more than 33,000 patients with first migraine consults, approximately two-thirds did not receive a neurology consultation during the study and received their migraine diagnosis in the primary care setting.

Of the 31% of patients with first migraine consults in primary care who later had a neurology consult, two-thirds received a migraine diagnosis from neurology. “The high rate of initial migraine diagnosis within neurology was surprising among this sample with primary care encounters first,” the researchers said.

The investigators also examined patient-reported outcomes from 391 respondents who received migraine care from neurology and 399 respondents who received migraine care from primary care. “Patients who consulted a neurologist were likely to report moderate-to-severe disability, poor acute treatment optimization, and major depression,” they said. “Allodynia, anxiety, and PTSD did not differ by type of provider.”

Confounding may have influenced the results, and the researchers plan to assess factors such as headache frequency and severity using patient-reported survey data in future analyses.
