Risk Factors for Headache in Youth Identified
, new data from a population-based study showed.
Children and teens with anxiety or mood disorders had twice the risk for frequent headaches, defined as occurring once or more per week, and those who regularly ate breakfast and dinners with their family had an 8% lower risk for frequent headaches than those who did not eat regular meals.
“It is not uncommon for children and teens to have headaches, and while medications are used to stop and sometimes prevent headaches, lifestyle changes also may offer an effective route to relief by preventing headaches from happening and improving quality of life,” study investigator Serena L. Orr, MD, MSc, University of Calgary in Alberta, Canada, said in a press release.
The findings were published online in Neurology.
Negative Consequences
Previous research shows frequent recurrent headaches occur in up to 30% of children and adolescents and can lead to lower academic achievement and lower quality of life.
Treatment recommendations often focus on adjusting lifestyle behaviors, such as sleep and meal timing or smoking.
To further investigate these links, researchers used data from the 2019 Canadian Health Survey on Children and Youth and included about 5 million children and teens aged 5-17 years. In most cases, a parent or guardian answered the survey questions.
In addition to assessing participants for headache frequency in the past week, the survey included questions about how often they had breakfast, were physically active, or spent playing video games or with a mobile device, for instance. Parents/guardians were also asked whether the youth had ever been diagnosed with a mood or anxiety disorder.
For participants aged between 12 and 17 years, there were also questions about smoking, alcohol consumption, and substance use.
The mean age of participants was 11 years, and 48% were female. About 6% of the participants had frequent recurrent headaches.
Investigators found that meal regularity was inversely associated with frequent headaches (P < .001). In an adjusted model, youth who often ate breakfast and dinner with their families had an 8% lower risk for frequent headaches than those who didn’t dine with their families regularly.
“It is possible regular family meals may lead to greater connectedness and communication within the family and better mental health outcomes, which in turn may impact headache frequency,” Dr. Orr noted.
Youth who spent more than 21 hours per week in front of computer screens or with video games had higher odds for frequent headaches (P < .001), but this association did not survive statistical adjustment for demographics or lifestyle factors.
Both mood and anxiety disorders were associated with twice the risk for frequent headaches, and this risk survived adjustment for age, sex, household income, and other lifestyle factors.
In adolescents aged 12-17 years, there was an association between drinking alcohol and frequent headache, with higher alcohol consumption increasing the likelihood of frequent headache. For instance, those who drank once or more per week had three times the risk for frequent headache (P < .001), and those who indulged in binge drinking at least five times per month had five times the risk for frequent headache (P < .001).
Smoking cannabis was also associated with frequent headache in a dose-dependent manner. Daily users had a threefold increased risk for frequent headache vs those who didn’t use cannabis (P < .001).
Similarly, those who smoked or used e-cigarettes daily also had a threefold increased risk for frequent headaches versus nonusers.
One of the study’s limitations was that it didn’t include participants living in foster homes, institutions or on First Nation reserves. Investigators also were not able to determine headache type and did not assess hydration, which can be an important lifestyle factor in headache etiology.
Prioritize Questions About Lifestyle?
In an accompanying editorial, Irene Patniyot, MD, of Baylor College of Medicine in Houston, Texas, noted that lifestyle advice is an important part of managing headache disorders in children and youth and questioned whether neurologists should prioritize discussions about lifestyle habits in this patient population. However, she noted, given the heavy demands on neurologists’ time, this may be “idealistic.”
One potential solution may lie in automating electronic questionnaires for inclusion in patients’ medical records. “Data extraction from electronic questionnaires has already led to new data on symptoms associated with headache in youth and can potentially lead to earlier identification and treatment of mental health disorders and lifestyle habits that negatively affect headache burden and overall well-being,” Dr. Patniyot wrote.
The study was funded by the Social Sciences and Humanities Research Council of Canada, the Canadian Institutes of Health Research, the Canada Foundation for Innovation, and Statistics Canada. Dr. Orr reported receiving royalties from Cambridge University Press; serving on the editorial boards of Headache, Neurology, and the American Migraine Foundation; and receiving research funding from the Canadian Institutes of Health Research and the Alberta Children’s Hospital Research Institute.

Neurological Disorders Now Top Global Cause of Illness, Disability
, a new comprehensive analysis showed.
In 2021, neurological conditions were responsible for 443 million years of healthy life lost due to illness, disability, and premature death — a measurement known as disability-adjusted life years (DALY) — making them the top contributor to the global disease burden, ahead of cardiovascular diseases.
Some 3.4 billion people — 43% of the entire global population — had a neurological illness in 2021, the report noted.
“As the world’s leading cause of overall disease burden, and with case numbers rising 59% globally since 1990, nervous system conditions must be addressed through effective, culturally acceptable, and affordable prevention, treatment, rehabilitation, and long-term care strategies,” lead author Jaimie Steinmetz, PhD, from the Institute of Health Metrics and Evaluation (IHME), University of Washington, Seattle, said in a news release.
The findings, from the Global Burden of Disease, Injuries, and Risk Factors Study (GBD) 2021, “have important health service and policy implications and serve as evidence that global neurological heath loss has been under-recognized and is increasing and unevenly distributed geographically and socioeconomically,” the authors noted.
The study was published online in The Lancet: Neurology.
The Top 10
The top 10 contributors to neurological health loss in 2021 were stroke, neonatal encephalopathy, migraine, Alzheimer’s disease and other dementias, diabetic neuropathy, meningitis, epilepsy, neurological complications from preterm birth, autistic spectrum disorders, and nervous system cancers.
Neurological consequences of COVID-19 ranked 20th out of 37 unique conditions assessed.
In 2021, there were more than 23 million global cases of COVID-19 with long-term cognitive symptoms or Guillain-Barré syndrome, accounting for 57% of all infectious neurological disease cases and contributing to 2.48 million years of healthy life lost, the study found.
The most prevalent neurological disorders were tension-type headache (about 2 billion cases) and migraine (about 1.1 billion cases), while diabetic neuropathy is the fastest-growing of all neurological conditions.
“The number of people with diabetic neuropathy has more than tripled globally since 1990, rising to 206 million in 2021. This is in line with the increase in the global prevalence of diabetes,” co-senior author Liane Ong, PhD, from IHME, said in the release.
The data showed striking differences in the burden of neurological conditions between world regions and national income levels, with over 80% of neurological deaths and health loss occurring in low- and middle-income countries.
Regions with the highest burden of neurological conditions were central and western sub-Saharan Africa, while high-income Asia Pacific and Australasia had the lowest burden.
“Nervous system health loss disproportionately impacts many of the poorest countries partly due to the higher prevalence of conditions affecting neonates and children under 5, especially birth-related complications and infections,” co-senior author Tarun Dua, MD, with the World Health Organization (WHO) brain health unit, noted in the news release.
“Improved infant survival has led to an increase in long-term disability, while limited access to treatment and rehabilitation services is contributing to the much higher proportion of deaths in these countries,” Dr. Dua said.
Prioritize Prevention
The analysis also provides estimates of the proportion of neurological conditions that are potentially preventable by eliminating known risk factors for stroke, dementia, multiple sclerosis, Parkinson’s disease, encephalitis, meningitis, and intellectual disability.
It shows that modifying 18 risk factors over a person’s lifetime — most importantly high systolic blood pressure — could prevent 84% of global DALYs from stroke. Controlling lead exposure could lower intellectual disability cases by 63% and reducing high fasting plasma glucose to normal levels could cut dementia by roughly 15%.
“Because many neurological conditions lack cures, and access to medical care is often limited, understanding modifiable risk factors and the potentially avoidable neurological condition burden is essential to help curb this global health crisis,” co-lead author Katrin Seeher, PhD, mental health specialist with WHO’s brain health unit, said in the release.
It’s important to note that nervous system conditions include infectious and vector-borne diseases and injuries as well as noncommunicable diseases and injuries, Dr. Steinmetz said, “demanding different strategies for prevention and treatment throughout life.”
“We hope that our findings can help policymakers more comprehensively understand the impact of neurological conditions on both adults and children to inform more targeted interventions in individual countries, as well as guide ongoing awareness and advocacy efforts around the world,” Dr. Steinmetz added.
In an accompanying editorial, Wolfgang Grisold, MD, president of the World Federation of Neurology, London, noted that the study builds on previous findings and expands the number of neurological conditions studied from 15 to 37.
“This important new GBD report highlights that the burden of neurological conditions is greater than previously thought,” wrote Dr. Grisold, who was not a part of the study. “In the next iteration, more attention should be given to neuromuscular diseases, the effects of cancer in the nervous system, and neuropathic pain. Comparing the disability caused by conditions with episodic occurrence versus those that cause permanent and progressive disease will remain challenging because the effects on the individuals vary substantially.”

FROM THE LANCET NEUROLOGY
Neurologists Read Signs to Diagnose Functional Neurological Disorders
They have gone by many different names over the centuries: hysteria, psychosomatic illnesses, psychogenic neurological disorders, conversion disorders, dissociative neurological symptom disorders. The terminology may change, but functional neurological disorders by any other name are still real and serious yet treatable phenomena.
Functional neurological disorders, or FNDs, live at the crossroads of neurology and psychiatry, and they are as much a product of the body as they are of the brain, say neurologists who specialize in treating these complex and clinically challenging conditions.
“Whether they’re easily recognized or not depends on someone’s training and experience in this regard,” said Mark Hallett, MD, of the Human Motor Control Section of the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland.
“The difficulty has been that there hasn’t been very good education about functional disorders over the last 50 years or so,” he said in an interview.
However, with training and experience, clinicians can learn to identify these common and disabling conditions, Dr. Hallett said.
Varying Definitions
The Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) labels FND as “conversion disorder,” and lists diagnostic criteria that include “one or more symptoms of altered voluntary motor or sensory function; clinical findings provide evidence of incompatibility between the symptom and recognized neurological or medical conditions; the symptom or deficit is not better explained by another medical or mental disorder;” and “the symptom or deficit causes clinically significant distress or impairment in social, occupational, or other important areas of functioning or warrants medical evaluation.”
Dr. Hallett offers his own definition of FND, which includes the following characteristics:
- A neurological disorder, characterized by almost any type of neurological symptom
- Not voluntarily produced
- Caused by a brain network dysfunction that does not exclude the possibility of normal function
- Sometimes due in part to a psychological cause, and not explained by other neurological pathology that may or may not be present
- Symptoms may be inconsistent (variable) or incompatible (incongruent) with other known neurological disorders or human anatomy and physiology.
The two most common types of FND are psychogenic nonepileptic seizures and functional movement disorders, but patients may also have functional sensory, visual, auditory, speech, and urologic disorders, and even functional coma.
Dr. Hallett cited studies showing that an estimated 9% of neurology hospital admission are for FNDS, and that among patients in neurology clinics 5.4% had a diagnosis of FND, and 30% had an FND as part of the diagnosis.
Women comprise between 60% and 75% of the population with FNDs.
Diagnosis
FND is not, as once thought, a diagnosis of exclusion, but is based on signs and symptoms, which may be either inconsistent or irreversible and may occur in the absence of a stressor, said Sara Finkelstein, MD, MSc, of the Functional Neurological Disorder Unit in the Department of Neurology at Massachusetts General Hospital in Boston.
She emphasized that there are several diagnostic pitfalls that clinicians need to be aware of.
For example, “just because a patient has a psychiatric history does not mean that they have a functional neurological disorder,” she said in an interview.
Clinicians may also make unwarranted assumptions about a given patient, excluding an FND diagnosis in, say, a young woman with symptoms of anxiety. Alternatively, clinicians may either include or exclude a diagnosis based on personality factors or on a prior stressor, neither of which alone are sufficiently diagnostic.
Additionally, a clinician may be tempted to make the diagnosis of an FND based on the absence of findings on standard exams rather than on rule-in signs and symptoms, she emphasized.
Functional seizures
A definitive diagnosis can depend on the type of disorder.
“Many functional seizures have some clinical manifestations that are apparent, but as seizures are intermittent the doctor may not see one, and it may depend upon someone taking a video of the person with the seizure perhaps, or bringing them into a hospital and watching them until they do have the seizure,” Dr. Hallett said.
There are some manifestations that indicate the likelihood that a seizure has a functional origin, and when there is uncertainty EEG can help to nail down a diagnosis, he added.
Dr. Finkelstein noted that exam signs with good reliability for functional seizures include eye closure or resistance to opening; duration longer than 2 minutes; stopping and starting; asynchronous limb movements; patient maintenance of awareness during a generalized event; and ictal weeping.
Differential diagnoses included migraine with complex aura, dissociation related to posttraumatic stress disorder, or anxiety.
Functional movement disorders
Dr. Finkelstein cautioned that when evaluating patients for potential functional movement disorders, it’s important to not jump to conclusions.
For example, the amplitude of tremor can vary in Parkinson’s disease and essential tremor as well as in functional tremor. The clinician should not read too much into the observation that a patient’s tremor gets worse with increasing stress as stress can exacerbate most tremor types, she said.
One sign that tremor could be functional (dystonic tremor) is irregularity of amplitude and frequency, she noted.
When assessing patients with gait disorder, it’s important to understand that there is no single sign that is specially characteristic for a given disorder, and just because a patient has a “bizarre” gait, it doesn’t necessarily signal a functional disorder.
“A dystonic gait may improve with an alternate motor pattern or be inconsistent over time,” Dr. Finkelstein said.
Treatment
In a comprehensive review published in The Lancet: Neurology in 2022, Dr. Hallett and colleagues said that good doctor-patient communications and understanding of each patient’s needs and goals are essential for effective treatment of all FNDs.
“Neurologists have traditionally avoided taking responsibility for people with FND, although are often most appropriate to engage patients in treatment. Explaining the diagnosis with clarity, confidence, using the principles of a ‘rule in’ process, is a key step in treatment,” they wrote.
Treatment can take several forms, depending on the FND, and may include physiotherapy for patients with functional movement disorders and psychological therapy for patients with functional seizures.
“With increasing evidence-based treatment, the diagnosis of FND should be seen as a process of looking for potentially reversible cause of disability and distress whether or not an individual has abnormalities on conventional laboratory or radiological testing,” Dr. Hallett and colleagues concluded.
This article was based on interviews and from presentations by Dr. Hallett and Dr. Finkelstein at a 2023 meeting of the Indiana Neurological Society. Dr. Hallett and Dr. Finkelstein declared no conflicts of interest.
They have gone by many different names over the centuries: hysteria, psychosomatic illnesses, psychogenic neurological disorders, conversion disorders, dissociative neurological symptom disorders. The terminology may change, but functional neurological disorders by any other name are still real and serious yet treatable phenomena.
Functional neurological disorders, or FNDs, live at the crossroads of neurology and psychiatry, and they are as much a product of the body as they are of the brain, say neurologists who specialize in treating these complex and clinically challenging conditions.
“Whether they’re easily recognized or not depends on someone’s training and experience in this regard,” said Mark Hallett, MD, of the Human Motor Control Section of the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland.
“The difficulty has been that there hasn’t been very good education about functional disorders over the last 50 years or so,” he said in an interview.
However, with training and experience, clinicians can learn to identify these common and disabling conditions, Dr. Hallett said.
Varying Definitions
The Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5) labels FND as “conversion disorder,” and lists diagnostic criteria that include “one or more symptoms of altered voluntary motor or sensory function; clinical findings provide evidence of incompatibility between the symptom and recognized neurological or medical conditions; the symptom or deficit is not better explained by another medical or mental disorder;” and “the symptom or deficit causes clinically significant distress or impairment in social, occupational, or other important areas of functioning or warrants medical evaluation.”
Dr. Hallett offers his own definition of FND, which includes the following characteristics:
- A neurological disorder, characterized by almost any type of neurological symptom
- Not voluntarily produced
- Caused by a brain network dysfunction that does not exclude the possibility of normal function
- Sometimes due in part to a psychological cause, and not explained by other neurological pathology that may or may not be present
- Symptoms may be inconsistent (variable) or incompatible (incongruent) with other known neurological disorders or human anatomy and physiology.
The two most common types of FND are psychogenic nonepileptic seizures and functional movement disorders, but patients may also have functional sensory, visual, auditory, speech, and urologic disorders, and even functional coma.
Dr. Hallett cited studies showing that an estimated 9% of neurology hospital admission are for FNDS, and that among patients in neurology clinics 5.4% had a diagnosis of FND, and 30% had an FND as part of the diagnosis.
Women comprise between 60% and 75% of the population with FNDs.
Diagnosis
FND is not, as once thought, a diagnosis of exclusion, but is based on signs and symptoms, which may be either inconsistent or irreversible and may occur in the absence of a stressor, said Sara Finkelstein, MD, MSc, of the Functional Neurological Disorder Unit in the Department of Neurology at Massachusetts General Hospital in Boston.
She emphasized that there are several diagnostic pitfalls that clinicians need to be aware of.
For example, “just because a patient has a psychiatric history does not mean that they have a functional neurological disorder,” she said in an interview.
Clinicians may also make unwarranted assumptions about a given patient, excluding an FND diagnosis in, say, a young woman with symptoms of anxiety. Alternatively, clinicians may either include or exclude a diagnosis based on personality factors or on a prior stressor, neither of which alone are sufficiently diagnostic.
Additionally, a clinician may be tempted to make the diagnosis of an FND based on the absence of findings on standard exams rather than on rule-in signs and symptoms, she emphasized.
Functional seizures
A definitive diagnosis can depend on the type of disorder.
“Many functional seizures have some clinical manifestations that are apparent, but as seizures are intermittent the doctor may not see one, and it may depend upon someone taking a video of the person with the seizure perhaps, or bringing them into a hospital and watching them until they do have the seizure,” Dr. Hallett said.
There are some manifestations that indicate the likelihood that a seizure has a functional origin, and when there is uncertainty EEG can help to nail down a diagnosis, he added.
Dr. Finkelstein noted that exam signs with good reliability for functional seizures include eye closure or resistance to opening; duration longer than 2 minutes; stopping and starting; asynchronous limb movements; patient maintenance of awareness during a generalized event; and ictal weeping.
Differential diagnoses included migraine with complex aura, dissociation related to posttraumatic stress disorder, or anxiety.
Functional movement disorders
Dr. Finkelstein cautioned that when evaluating patients for potential functional movement disorders, it’s important to not jump to conclusions.
For example, the amplitude of tremor can vary in Parkinson’s disease and essential tremor as well as in functional tremor. The clinician should not read too much into the observation that a patient’s tremor gets worse with increasing stress as stress can exacerbate most tremor types, she said.
One sign that tremor could be functional (dystonic tremor) is irregularity of amplitude and frequency, she noted.
When assessing patients with gait disorder, it’s important to understand that there is no single sign that is specially characteristic for a given disorder, and just because a patient has a “bizarre” gait, it doesn’t necessarily signal a functional disorder.
“A dystonic gait may improve with an alternate motor pattern or be inconsistent over time,” Dr. Finkelstein said.

FROM THE INDIANA NEUROLOGICAL SOCIETY’S FUNCTIONAL NEUROLOGICAL DISORDERS CONFERENCE
Long-term Fremanezumab Effective and Safe in Hard-to-Treat Migraine
Key clinical point: Long-term fremanezumab treatment appears to be highly effective, safe, and well tolerated in patients with high-frequency episodic migraine (HFEM) or chronic migraine (CM) who have experienced multiple (more than three) treatment failures and have various comorbidities.
Major finding: At 48 weeks, fremanezumab led to significant reductions in the monthly migraine days in patients with HFEM (mean change −6.4 days) and monthly headache days in patients with CM (mean change −14.5 days; both P < .001). Overall, 7.8% of patients reported mild and transient treatment-emergent adverse events, and none of the patients discontinued the treatment for any reason.
Study details: This prospective, multicenter, cohort study included 130 patients with migraine (49 with HEFM; 81 with CM) and multiple treatment failures who received fremanezumab for at least 48 weeks (≥ 12 doses).
Disclosures: This study was partially supported by the Italian Ministry of Health (Institutional Funding Ricerca Corrente) San Raffaele and Fondazione Italiana Cefalee. Several authors declared receiving travel grants, research support, or honoraria from or having other ties with various sources. Twenty authors declared no conflicts of interest.

Endometriosis and Concomitant Migraine Tied to Severe Pain and Disability
Key clinical point: Untreated women with endometriosis and concomitant migraine (EM-MO) experienced more severe symptoms and frequent painful days than those with endometriosis alone (EM-O) or migraine alone (MG-O).
Major finding: The prevalence of severe adenomyosis (14% vs 4%; P = .027) and posterior (48% vs 30%; P = .031) and anterior (10% vs 2%; P = .029) deep infiltrating endometriosis was higher in women with EM-MO vs EM-O. Women with EM-MO vs MG-O had significantly higher pain intensity (visual analogue scale scores 8.44 vs 7.74; P = .004), monthly migraine days (6.68 vs 5.44 days; P = .042), and Headache Impact Test-6 scores (62.33 vs 57.38; P = .010).
Study details: This prospective case-control study included 50 women with EM-MO and matched control patients with EM-O (n = 100) and MG-O (n = 100) who underwent pelvic and neurologic examination.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.

Higher Prevalence of Migraine in Women with Inflammatory Bowel Disease
Key clinical point: Migraine is more prevalent among patients with inflammatory bowel disease (IBD), especially women, suggesting an influence of sex-related factors.
Major finding: The prevalence of migraine was significantly higher in patients with IBD (20.8%; P < .0001) than in the general population (12.6%; P < .0001), and this association was statistically significant in women (29.8%; P < .0001) but not in men (9.6%; P = .30). However, there were no significant differences in migraine prevalence between patients with ulcerative colitis and those with Crohn’s disease (P = .88).
Study details: This cross-sectional study included 283 patients age 18-65 years with IBD, of whom 20.85% had definite (11.66%) or probable (9.18%) migraine based on their response to the ID-Migraine questionnaire.
Disclosures: This study was funded by the Instituto de Salud Carlos III, Spain, and Fondos Europeos de Desarrollo Regional. The authors declared no conflicts of interest.

Increased Headache Burden With Left vs Right-Sided Migraine
Key clinical point: Patients with migraine experiencing typically left-sided headache during attacks had a higher burden of headache frequency and severity than those experiencing typically right-sided headache.
Major finding: Patients with left-sided vs right-sided migraine had 3.5 (95% CI 0.6-6.4) fewer headache-free days and 3.3 (95% CI 1.3-5.4) more severe headache days per 4 weeks. There were no other significant differences in migraine characteristics or psychiatric comorbidities between patients with left- and right-sided migraine.
Study details: This cross-sectional study included 340 patients with migraine, of whom 166 (48.8%) and 174 (51.2%) had left- and right-sided migraines, respectively.
Disclosures: The study did not disclose any funding source. The authors declared no conflicts of interest.

Erenumab May Worsen Hypertension in Patients with Migraine
Key clinical point: Nearly a quarter of patients with migraine who initiated erenumab experienced worsening blood pressure (BP), especially those with atrial fibrillation, highlighting the need for routine BP monitoring among these patients.
Major finding: Among patients with migraine receiving erenumab, 23.3% had worsening BP and 3.9% had an improvement in BP, with the risk of worsening BP being significantly higher among those with atrial fibrillation (adjusted odds ratio 4.72; P = .040). However, worsening BP was not associated with preexisting hypertension, sex, body mass index, and age.
Study details: This single-center observational retrospective cohort study included patients with migraine with (n = 70) and without (n = 265) preexisting hypertension who were treated with erenumab.

Comparing Efficacy and Safety of Atogepant and Rimegepant for Migraine Prevention
Key clinical point: Atogepant led to greater improvements in efficacy and quality of life than rimegepant in patients with episodic migraine (EM), although both treatments had comparable safety profiles.
Major finding: Atogepant vs rimegepant led to significantly greater reductions in mean monthly migraine days (mean difference [MD] −1.65; P < .001) and acute medication use days (MD −2.08; P < .0001) across 1-12 weeks and significantly greater improvements in Migraine-Specific Quality of Life questionnaire version 2.1 Role Function-Restrictive domain scores at 12 weeks (MD 7.36; P < .01). Both treatments had comparable safety or tolerability profiles.
Study details: This anchored matching-adjusted indirect comparison analysis compared the efficacy and safety or tolerability of once-daily atogepant (60 mg) and once-every-other-day rimegepant (75 mg) for EM prevention using data from two phase 3 trials for atogepant (ADVANCE and PROGRESS) and one phase 2/3 trial for rimegepant.
Disclosures: This study was funded by AbbVie. Four authors declared being employees of or holding stocks in AbbVie at the time of the study. Two authors are employees of Luminity, which was paid by AbbVie for the statistical analyses in this study. The other authors declared ties with various sources, including AbbVie. One author is an associate editor of Cephalalgia.

OnabotulinumtoxinA Reduces Interictal Burden and Allodynia Severity in Chronic Migraine
Key clinical point: OnabotulinumtoxinA (BoNTA) had beneficial effects in reducing frequency or severity of interictal burden and cutaneous allodynia in patients with chronic migraine (CM).
Major finding: After three courses of BoNTA treatment, median Migraine Interictal Burden Scale-4 scores significantly reduced from 9 at baseline to 2 (z −7.222), median Allodynia Symptom Checklist-12 scores significantly reduced from 6 at baseline to 1 (z −5.393), and median pain intensity numerical rating scale scores for hair brushing significantly reduced from 5 at baseline to 1 (z −5.398; all P < .001).
Study details: This prospective open-label study included 70 BoNTA-naive patients with CM who received three consecutive cycles of BoNTA.
Disclosures: This study did not receive any funding. Several authors declared receiving investigator fees or travel grants from or serving as advisory board members or consultants for various sources.
