Headache & Migraine

Key clinical point: Erenumab is effective and well tolerated in patients with chronic migraine who did not respond to previous migraine treatments.

Major finding: Overall, 71.4% of patients treated with erenumab achieved ≥30% reduction in monthly migraine days from baseline to 9-12 weeks and 34.0% of patients at all assessment periods through 52 weeks. Constipation was the most common adverse event and 13.7% of patients discontinued treatment because of a lack of tolerability.

Study details: The data come from a 52-week, prospective, observational study including 300 patients with chronic migraine who received ≥1 dose of erenumab, of which 273 and 119 patients completed 12 and 52 weeks of treatment, respectively.

Disclosures: This study was funded by and conducted in collaboration with Novartis Pharma AG, Basel, Switzerland. Some authors reported being consultants, speakers, or scientific advisors for or receiving personal fees from various sources, including Novartis.

Key clinical point: Intravenous (IV) ketorolac plus metoclopramide failed to improve pain intensity in children presenting to the emergency department (ED) for the acute treatment of migraine compared with metoclopramide monotherapy.

Major finding: The mean change in pain intensity as assessed by a 100 mm Visual Analog Scale at 120 minutes was −44 mm (95% CI 32-57 mm) in the monotherapy group and −36 mm (95% CI 23-49 mm) in the ketorolac group, corresponding to a mean difference of 8 mm between the groups (P = .355), with no significant between-group difference in headache recurrence and adverse events.

Study details: Findings are from a double-blind, randomized placebo-controlled trial including 53 children aged 6-17 years presenting to the ED for the acute treatment of migraine. They were randomly assigned to receive IV ketorolac plus metoclopramide (n = 26) or IV metoclopramide plus placebo (n = 27).

Contrary to previous research findings, the stress of the COVID-19 pandemic has been linked to an increased headache burden in teens.

Investigators found factors contributing to headache for preteens and teens during the pandemic included increased screen time for online learning, depression, anxiety, female sex, and weight gain.

“The stressors and pressures of the pandemic may have eventually taken their toll,” lead author Ayşe Nur Özdağ Acarli, MD, Ermenek State Hospital, department of neurology, Karaman, Turkey, told this news organization.

“Limiting screen time and providing more psychosocial supports would help lessen the burden of the COVID-19 pandemic on adolescents with headache.”

The findings were presented at the Congress of the European Academy of Neurology (EAN) 2022.
 

Most common neurological problem in kids

Headache is the most common neurological problem in children and adolescents. Potential factors contributing to headache in this population include lack of sleep and physical activity, mental health problems, and socioeconomic conditions.

The COVID-19 pandemic has had a “striking” impact on every aspect of life for young people, said Dr. Acarli.

Some studies reported an improvement in headache prevalence among adolescents during COVID-19, which was attributed to less school-related stress. However, said Dr. Acarli in her personal clinical experience, young patients suffered more frequent and severe headaches during the pandemic.

She noted previous research examining the impact of the pandemic on headache in youth was conducted only in the early days of the pandemic and examined shorter-term effects. Research examining the long-term effects of the pandemic on headache in this patient population has been “lacking,” she said.

The study included 851 participants aged 10-18 years (mean age 14.9 years and 62% female) who were seen at a neurology or pediatric outpatient clinic from August-December 2021. The study excluded subjects with neurological problems, intellectual deficits, autism spectrum disorder, and epilepsy.

Participants completed detailed questionnaires providing data on demographics, exposure to COVID-19, and electronics, as well as information on depressive symptoms as assessed by the Patient Health Questionnaire-9 and anxiety symptoms using the Generalized Anxiety Disorder-7 and COVID-related anxiety.

“We used two distinct scales for anxiety: one for generalized anxiety and the other for COVID-related anxiety,” said Dr. Acarli.

Of the total study population, 756 (89%) reported headaches. This headache prevalence in children and adolescents is like that found in other studies.

Dr. Acarli noted several differences in the headache group versus the non-headache group. The female/male ratio was 2:1 versus 1:1, the mean age was 15.0 versus 14.4, and depression and generalized anxiety scores were significantly higher. There was no significant difference in COVID-19 history in those with and without headache.

Researchers categorized those with headache into four groups: worsening headaches (27%), improved headaches (3%), new onset headaches (10%), and stable headaches (61%).

Compared with the other groups, the worsened headache group included significantly more females and older individuals with more severe and frequent headaches. This group also had more participants reporting at least 15 headache attacks a month and using painkillers at least once a month.

The study showed headache severity was significantly increased with age, headache duration, depression, generalized anxiety (all P < .001), and COVID-19 anxiety (P < .01). Headache frequency, measured as attacks per month, was significantly increased with age, depression, and generalized anxiety (all P < .001).

Worsening headache outcomes during the pandemic were associated with longer exposure to computer screens (odds ratio, 1.7; 95% confidence interval, 1.2-2.3; P < .01), lack of suitable conditions for online learning (OR, 2.6; 95% CI, 1.8-3.8; P < .001), depression (OR, 2.0; 95% CI, 1.4-2.8; P < .001); and COVID-19 anxiety (OR, 3.2; 95% CI, 1.3-8.0; P < .01). Other contributing factors included school exams, living in a city, female sex, and weight gain.

There may be a link between COVID-related headaches and anxiety or depression, but it’s unclear what’s causing what. “We don’t know which is the chicken and which is the egg,” said Dr. Acarli.
 

Headache triggers

Commenting for this news organization, Raquel Gil-Gouveia, MD, PhD, head of the neurology department, Hospital da Luz, Lisbon, Portugal, who co-chaired the session where the research was presented, said the information collected for the study was “extensive.”

Some results were expected, including the fact that patients with headaches were more anxious and depressed, said Dr. Gil-Gouveia.

“Anxiety and depression are frequent comorbidities of headache and can act as a triggering factor for headache attacks but can also be a consequence of intense or chronic pain,” she said.

She agreed the new results differ from those of studies carried out during the first pandemic lockdown, which showed an improvement in headache, but noted online learning was not fully implemented at that time, “so it was much like being on vacation.”

In addition to isolation, anxiety, and prolonged screen exposure, the lack of peer contact and fewer sports and leisure activities may also have contributed to worsening headaches during the COVID lockdown, but these were not explored in this study, said Dr. Gil-Gouveia.

The study was supported by the Global Migraine and Pain Society. The investigators and Dr. Gil-Gouveia report no relevant financial relationships.

She noted previous research examining the impact of the pandemic on headache in youth was conducted only in the early days of the pandemic and examined shorter-term effects. Research examining the long-term effects of the pandemic on headache in this patient population has been “lacking,” she said.

The study included 851 participants aged 10-18 years (mean age 14.9 years and 62% female) who were seen at a neurology or pediatric outpatient clinic from August-December 2021. The study excluded subjects with neurological problems, intellectual deficits, autism spectrum disorder, and epilepsy.

Participants completed detailed questionnaires providing data on demographics, exposure to COVID-19, and electronics, as well as information on depressive symptoms as assessed by the Patient Health Questionnaire-9 and anxiety symptoms using the Generalized Anxiety Disorder-7 and COVID-related anxiety.

“We used two distinct scales for anxiety: one for generalized anxiety and the other for COVID-related anxiety,” said Dr. Acarli.

Of the total study population, 756 (89%) reported headaches. This headache prevalence in children and adolescents is like that found in other studies.

Dr. Acarli noted several differences in the headache group versus the non-headache group. The female/male ratio was 2:1 versus 1:1, the mean age was 15.0 versus 14.4, and depression and generalized anxiety scores were significantly higher. There was no significant difference in COVID-19 history in those with and without headache.

Researchers categorized those with headache into four groups: worsening headaches (27%), improved headaches (3%), new onset headaches (10%), and stable headaches (61%).

Compared with the other groups, the worsened headache group included significantly more females and older individuals with more severe and frequent headaches. This group also had more participants reporting at least 15 headache attacks a month and using painkillers at least once a month.

The study showed headache severity was significantly increased with age, headache duration, depression, generalized anxiety (all P < .001), and COVID-19 anxiety (P < .01). Headache frequency, measured as attacks per month, was significantly increased with age, depression, and generalized anxiety (all P < .001).

Worsening headache outcomes during the pandemic were associated with longer exposure to computer screens (odds ratio, 1.7; 95% confidence interval, 1.2-2.3; P < .01), lack of suitable conditions for online learning (OR, 2.6; 95% CI, 1.8-3.8; P < .001), depression (OR, 2.0; 95% CI, 1.4-2.8; P < .001); and COVID-19 anxiety (OR, 3.2; 95% CI, 1.3-8.0; P < .01). Other contributing factors included school exams, living in a city, female sex, and weight gain.

There may be a link between COVID-related headaches and anxiety or depression, but it’s unclear what’s causing what. “We don’t know which is the chicken and which is the egg,” said Dr. Acarli.
 

Headache triggers

Commenting for this news organization, Raquel Gil-Gouveia, MD, PhD, head of the neurology department, Hospital da Luz, Lisbon, Portugal, who co-chaired the session where the research was presented, said the information collected for the study was “extensive.”

Some results were expected, including the fact that patients with headaches were more anxious and depressed, said Dr. Gil-Gouveia.

“Anxiety and depression are frequent comorbidities of headache and can act as a triggering factor for headache attacks but can also be a consequence of intense or chronic pain,” she said.

She agreed the new results differ from those of studies carried out during the first pandemic lockdown, which showed an improvement in headache, but noted online learning was not fully implemented at that time, “so it was much like being on vacation.”

In addition to isolation, anxiety, and prolonged screen exposure, the lack of peer contact and fewer sports and leisure activities may also have contributed to worsening headaches during the COVID lockdown, but these were not explored in this study, said Dr. Gil-Gouveia.

The study was supported by the Global Migraine and Pain Society. The investigators and Dr. Gil-Gouveia report no relevant financial relationships.

Contrary to previous research findings, the stress of the COVID-19 pandemic has been linked to an increased headache burden in teens.

Investigators found factors contributing to headache for preteens and teens during the pandemic included increased screen time for online learning, depression, anxiety, female sex, and weight gain.

“The stressors and pressures of the pandemic may have eventually taken their toll,” lead author Ayşe Nur Özdağ Acarli, MD, Ermenek State Hospital, department of neurology, Karaman, Turkey, told this news organization.

“Limiting screen time and providing more psychosocial supports would help lessen the burden of the COVID-19 pandemic on adolescents with headache.”

The findings were presented at the Congress of the European Academy of Neurology (EAN) 2022.
 

Most common neurological problem in kids

Headache is the most common neurological problem in children and adolescents. Potential factors contributing to headache in this population include lack of sleep and physical activity, mental health problems, and socioeconomic conditions.

DENVER – A new study finds that females with male twins are more likely to suffer from migraines without aura than are those with female twins, even though testosterone is thought to be protective. The findings, presented at the annual meeting of the American Headache Society, also hint at a possible role played by the prenatal environment.

The study marks the first time a large-scale twin dataset has been used to assess sex differences in underlying genetic factors of migraine, lead author Morgan Fitzgerald, a senior research associate at the University of California at San Diego, said in a presentation at the conference. The findings were previously published in Frontiers in Pain Research.
 

More than genetics

The researchers analyzed data regarding 51,872 participants in the Swedish Twin Registry. According to Dr. Fitzgerald, the database is ideal because it is large and includes both genders.

Per the database, female twins were more likely to have migraines without aura than were male twins (17.6% vs. 5.5%, respectively), reflecting global numbers that suggest 18% of females and 6% of males have migraines each year.

To better understand heritability, the researchers compared identical twins with fraternal twins, and looked for gender-related correlations, Dr. Fitzgerald said.

One analysis suggests that migraine is equally heritable in men and women with a broad sense heritability of 0.45 (95% confidence interval [CI], 0.40-0.50). However, another analysis model provides evidence “that there are differences in the underlying genetic factors contributing to migraine across males and females,” she said.

Unexpectedly, the researchers also found that females with male twins were more likely to have migraines than were those with female twins (odds ratio, 1.51, 95% CI, 1.26-1.81) even though males are less affected by the headaches.

“These results suggest that the prominent sex difference in migraine prevalence is not entirely accounted for by genetic factors, while demonstrating that masculinization of the prenatal environment may increase migraine risk for females,” the authors wrote in the published study. “This effect points to a potential prenatal neuroendocrine factor in the development of migraine.”
 

Probing the migraine gender gap

Commenting on the research, University of Texas at Dallas neuroscientist and headache researcher Gregory Dussor, PhD, said the new study is “a very unique approach to address the question of nature versus nurture in migraine. It was well designed and used robust statistical modeling.”

As for the findings, “the conclusion that genetics do not explain sex differences in migraine risk by themselves is not surprising given how big of a role hormones in later life are likely to play in the disease and how many factors there are that can influence hormone levels,” he said.

“On the other hand, the surprising part of the findings was that the presence of a male co-twin increases risk of migraine in females. I would have expected to see the opposite, given the lower prevalence of migraine in males and the seemingly protective role that male hormones can play in migraine.”

Overall, the study adds to data implicating environment and hormones in the migraine gender gap, he said. “One thing I wonder from this study is what influence a female co-twin growing up with a male co-twin can have on migraine susceptibility. That female co-twin may end up with a very different set of childhood experiences than if she was with another female co-twin. Twins generally spend an enormous amount of time together and the same sex versus opposite sex experiences are likely to be quite different. This may have an influence on migraine later in life.”

As for the value of the study in terms of diagnosis, treatment, or prevention of migraine, Dr. Dussor said, “it’s possible it could help to identify risk factors for higher migraine susceptibility but it’s far too early to know how this could be used.”

The authors have no disclosures. Dr. Dussor disclosed an NIH-funded grant to study the role of the hormone prolactin in preclinical migraine models.

Acupuncture deep needling provides significant, long-term relief from chronic tension type headache (TTH), new research suggests. Result of a randomized trial showed that though the majority of participants reported some relief from TTH after 8 weeks of acupuncture treatment, those who received needling at a depth of 12.5-20.0 mm reported the greatest reduction in headache frequency and severity.

At this depth, acupuncture promotes deqi sensation, a feeling of numbness, soreness, heaviness, or irritating pain in the needling site that is considered key to successful acupuncture treatment in traditional Chinese acupuncture theory.

“Our study showed that deqi sensation could enhance the effect of acupuncture in the treatment of chronic TTH, and the effect of acupuncture lasted at least 6 months when the treatment was stopped,” said co-investigator Ying Li, MD, PhD, The Third Hospital/Acupuncture and Tuina School, Chengdu University of Traditional Chinese Medicine, China.

The findings were published online in Neurology.
 

Deqi sensation key

TTH is the most common type of headache, with a lifetime prevalence of up to 78% in some studies. The pain is often described as throbbing or a vice-like tightness on both sides of the head. TTH is considered chronic when it occurs at least 15 days a month.

Previous studies have suggested that acupuncture can offer relief from headache pain, but specific information on TTH, especially chronic TTH, has been lacking.

To address the issue, researchers designed a parallel-design, patient-and-assessor blinded randomized controlled trial with 218 individuals with a history of chronic TTH. All were untreated with prophylactic treatment in the previous 3 months.

The treatment group (n = 110) received 20 sessions of true acupuncture (TA) over 8 weeks. This included three sessions per week in the first 4 weeks and two sessions per week in the last 4 weeks. The depth of needling at each point ranged from 12.5 to 20 mm, which is needed to achieve deqi sensation.

The control group (n = 108) received superficial acupuncture (SA) on the same schedule as the TA group and at traditional acupuncture points. However, this was done at a maximum depth of 2 mm, which is not deep enough for deqi sensation.

At week 16, 68.2% of the participants receiving TA reported a greater than 50% reduction in monthly headache days, compared with 48.1% of those receiving SA (odds ratio, 2.65; P < .001).

Mean monthly headache days decreased from 20.38 days at baseline to 7.48 days at week 32 in the TA group versus 22.6 days at baseline to 11.94 days in the SA group.

Headache intensity and severity decreased in both groups, although those who achieved deqi sensation reported the most improvement.

Only four patients reported adverse effects, all of which were mild and none requiring treatment.

Patients in both groups reported some pain relief, suggesting that those who are not comfortable with deqi sensation may still benefit from superficial acupuncture, although to a lesser extent, Dr. Li said.

“We assume that the point-specific effect and placebo effect were combined to give the patients relief of headaches,” Dr. Li added. “Further, the effect of deqi sensation added more treatment effect. This might be explained by gate-control theory or other unknown mechanisms.”
 

Deeper understanding?

Commenting on the research, Jennifer Bickel, MD, a senior member of neurology at Moffit Cancer Center and professor of oncologic sciences at University of South Florida, Tampa, said that the study provides a deeper understanding of acupuncture’s efficacy for chronic TTH, which could aid clinicians who are unfamiliar with the therapy or when and how to refer treatment.

“This study provides a more descriptive outline for what type of acupuncture treatment and duration can be effective for patients so doctors can prep patients on what to expect and so doctors can better assess if patients received appropriate acupuncture for their headaches,” said Dr. Bickel, who was not involved with the research.

However, she noted that the acupuncture sites and techniques did not vary during the trial. Although that makes sense for a controlled study, it may not reflect real-world clinical practice, she added.

“The downside is that the study didn’t fully reflect that most acupuncturists in clinical practice would alter treatments during the 20 sessions based on the patient’s response and accompanying symptoms or comorbidities,” Dr. Bickel said.

The study also lacked information on medication overuse headache or patients’ prior history of TTH treatments.

“This could be helpful to understand which patients in clinical practice are most likely to benefit from treatment,” Dr. Bickel said.

Study authors received funding from the Department of Science and Technology of Sichuan Province and the National Natural Science Foundation of China. Dr. Li, Dr. Bickel, and Dr. Vickers report no relevant financial relationships.

“The downside is that the study didn’t fully reflect that most acupuncturists in clinical practice would alter treatments during the 20 sessions based on the patient’s response and accompanying symptoms or comorbidities,” Dr. Bickel said.

The study also lacked information on medication overuse headache or patients’ prior history of TTH treatments.

“This could be helpful to understand which patients in clinical practice are most likely to benefit from treatment,” Dr. Bickel said.

Study authors received funding from the Department of Science and Technology of Sichuan Province and the National Natural Science Foundation of China. Dr. Li, Dr. Bickel, and Dr. Vickers report no relevant financial relationships.
