Lidocaine Nerve Block Effective for Severe, Refractory Migraine in Children
DENVER — , results of a randomized controlled trial show.
Investigators found children receiving bilateral occipital nerve blocks with 2% lidocaine had significantly greater pain relief than that of peers receiving saline injections.
Cases series have shown a benefit of peripheral nerve blocks (PNBs) — injections of local anesthetics over branches of the occipital or trigeminal nerve — for severe, refractory headache in children.
Although 80% of pediatric headache specialists use PNBs, there is “inconsistent insurance coverage” for this treatment, which had not been tested in a randomized controlled trial in children before now, lead investigator Christina Szperka, MD, with the Pediatric Headache Program, Department of Neurology, University of Pennsylvania Perelman School of Medicine, Philadelphia, told delegates attending the 2024 annual meeting of the American Academy of Neurology.
Significant Results
Investigators enrolled 58 children and adolescents with acute status migrainosus. The mean age was 16 years, and reported gender was female for 44 participants, male for 11 participants, and nonbinary or transgender in 3 participants. Participants had a migraine flare duration of 22 days and had not responded to other treatments.
All participants had topical lidocaine cream applied for 30 minutes as a run-in step and could decline injections if they experienced sufficient benefit from cream alone.
“We used a lidocaine cream lead-in for two reasons. One was to try to see if we could address the issue of high placebo response in pediatric trials in particular, and also to see if we could help with blinding to injection,” said Dr. Szperka.
Topical lidocaine cream led to a small decrease in pain score overall (0.2 point on a 0-10 scale), and all participants proceeded to randomized blinded bilateral greater occipital nerve injection with 2% lidocaine or saline, she reported.
On the primary endpoint — change in pain score at 30 minutes — lidocaine was significantly more effective than saline, achieving a 2.3-point decrease on average (on a 0-10 scale) vs a 1.1-point decrease with saline (P = .01).
A 2-point pain reduction was achieved in 69% of patients in the lidocaine group versus 34% in the saline group.
Three quarters (76%) of patients getting lidocaine reported at least partial relief in severity or location of pain compared with 48% of those getting saline (P = .03). Rates of pain freedom at 30 minutes were 17% and 7%, respectively, and at 24 hours were 14% and 0%, respectively.
The majority of adverse events were mild and fairly equal across groups and included anxiety, worsening headache, injection site pain, dizziness, and numbness (more so with lidocaine). There was one case of anaphylaxis after lidocaine injection.
Quite unexpectedly, said Dr. Szperka, patients rated the saline injection as more painful than the lidocaine injection. “This was not what I expected going in, and I think is relevant for future trials,” she said.
Encouraging Results
Reached for comment, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, said that as a neurologist and pain physician, he sees firsthand the “devastating impact of status migrainosus on children.”
“These debilitating headaches can rob them of precious school days, hindering learning and social interaction,” said Dr. Lakhan. “The constant pain and fear of the next attack can also take a toll on their emotional well-being.”
The impact on families is significant as well, highlighting the need to find more effective treatments, Dr. Lakhan said.
“Traditionally, we’ve relied on case studies to see the benefits of nerve blocks for migraine in younger patients. This is the first randomized controlled trial that shows lidocaine injections can be significantly more effective than a placebo for these unrelenting migraines,” he said.
“It’s important to note that this is a relatively small study, and not without safety concerns, including rare but potentially life-threatening anaphylaxis to lidocaine,” Dr. Lakhan added. “More research is needed, but these findings are encouraging. Lidocaine injections could become a valuable tool for managing treatment-resistant migraines in adolescents and young adults.”
The study was supported by a grant from the National Institute of Neurological Disorders and Stroke.

FROM AAN 2024
Vaporized Cannabis for Acute Migraine Yields Rapid, Sustained Relief
DENVER — , new research suggests.
“In this single-center randomized controlled trial across 247 treated migraine attacks, four puffs of vaporized THC-CBD mix were efficacious for acute migraine treatment,” said study investigator Nathaniel Marc Schuster, MD, with University of California San Diego Center for Pain Medicine.
The superiority of THC-CBD over placebo was “unlikely explained by unmasking given that in our blinding analysis most patients who got THC actually did not think they got some THC,” Dr. Schuster said.
He presented the results at the 2024 annual meeting of the American Academy of Neurology.
Sustained Pain Relief
Preclinical and retrospective studies point to antimigraine effects of cannabinoids, yet strong evidence of efficacy from a randomized controlled trial has been lacking.
The researchers tested the efficacy of cannabis for acute migraine in what they report is the first randomized, double-blind, placebo-controlled, crossover trial of adults with migraine.
Participants treated up to four separate moderate to severe migraine attacks, each with one of four different treatments. The four treatments were: 6% THC, 11% CBD, a mix of 6% THC and 11% CBD, or placebo flower from the National Institute on Drug Abuse that has a similar taste and smell to the other products.
The four treatments were vaporized in a randomized order, with at least 1 week washout between treatments. The primary endpoint was pain relief at 2 hours from vaporization. Secondary endpoints were freedom from pain and most bothersome symptom (MBS) at 2 hours from vaporization.
Of the 92 enrolled patients (mean age 41 years, 83% women), 19 treated zero migraine attacks thus leaving 73 patients who treated a total of 247 migraine attacks over the 1-year study.
The THC-CBD mix was superior to placebo at achieving pain relief (67.2% vs 46.6%; P = .016), pain freedom (34.5% vs 15.5%; P = .017), and MBS freedom (60.3% vs 34.5%; P = .005) at 2 hours.
The THC-CBD mix was also superior to placebo for sustained pain freedom at 24 hours and sustained MBS freedom at 24 and 48 hours.
There were no serious adverse events. The THC-CBD mix was better tolerated than THC-only was, with lower rates of euphoria and cognitive impairment and lower subjective highness, Dr. Schuster said.
Adverse events were more common with THC only (vs THC-CBD) “and this is really expected because CBD is known to bring down the side effects of THC,” Dr. Schuster noted.
Summing up his presentation, Dr. Schuster said, “This is one single-center study, and, of course, we need more data. We need to study the rates of medication overuse headache and the rates of cannabis use disorder that may develop with the use of cannabis for migraine.”
Cautious Optimism
Reached for comment, Hsiangkuo (Scott) Yuan, MD, PhD, Department of Neurology, Thomas Jefferson University, and director of clinical research, Jefferson Headache Center, Philadelphia, Pennsylvania, noted that the “statistically significant” differences between THC-CBD versus placebo on 2-hour pain relief, pain freedom and MBS freedom are “certainly very exciting, especially when no serious adverse event was reported.”
“Since THC has a narrow therapeutic window for analgesia (too high causes psychoactive side effects and may even worsen the pain), its dosing needs to be carefully controlled. The study was wisely designed to ensure uniform dosing from the vaporizer, which is usually safer than smoking or a vape pen and has a quicker onset than ingestion for acute usage,” said Dr. Yuan, who was not involved in the study.
“However, the optimal THC-CBD ratio and potency (percent THC) for acute migraine remain to be studied. Perhaps there is an individualized dose that can be obtained by titration. We also don’t know if the effect changes after repeated use,” Dr. Yuan cautioned.
He also noted that cannabis use was associated with medication overuse headache in a retrospective study, “although the causality remains to be determined.”
“While there was no serious adverse event, it is not completely risk-free, especially when cannabis is used repeatedly for a short duration. Since the physician does not have direct control over what happens at the dispensary, we need to counsel our patients more carefully when recommending cannabis/cannabinoids,” Dr. Yuan said.
Overall, he said he is “cautiously optimistic about cannabis use for acute migraine.”
This was an investigator-initiated study, with no commercial funding. Dr. Schuster has disclosed relationships with Schedule 1 Therapeutics, Averitas, Lundbeck, Eli Lilly, ShiraTronics, and Syneos. In the past 24 months, Dr. Yuan has served as a site investigator for Teva, AbbVie, Ipsen, Parema; received advisory/consultant fees from Salvia, Pfizer, AbbVie, Cerenovus; and royalties from Cambridge University Press and MedLink.

FROM AAN 2024
IV Ketamine Promising for Severe Refractory Headache in Children
DENVER — , new research suggests. In a retrospective chart review, IV ketamine led to in a 50% reduction in pain at discharge, with “nearly two-thirds” of patients having no recurrence within 30 days, noted lead investigator Scott Rosenthal, MD, from the University of Colorado Anschutz Medical Campus, Aurora.
Dr. Rosenthal reported the findings at the 2024 annual meeting of the American Academy of Neurology.
Statistically Significant Pain Relief
“IV ketamine has shown benefit in nonheadache chronic pain syndromes and refractory mood disorders. Patients with refractory status migraines are often left with ongoing pain and dysfunction after failing typical interventions,” Dr. Rosenthal said.
“Ketamine has emerged as a potential treatment option in this population. However, there’s very little research on the efficacy and tolerability of it in general as well as the pediatric population,” he noted.
Dr. Rosenthal and colleagues took a look back at patients admitted to Children’s Hospital Colorado between 2019 and 2022 for treatment of severe refractory headache who were treated with continuous IV ketamine.
They analyzed 68 encounters of 41 unique patients aged 5-21 years (median age 16 years; 85% girls). Chronic migraine without aura made up 79% of cases.
On presentation, most patients had an exacerbation or ongoing worsening of pain for about 10 days, and all but two were taking a preventive medication. Nearly 70% had a comorbid psychiatric diagnosis such as anxiety or depression, and 60% had a comorbid chronic pain diagnosis separate from their headache diagnosis.
The primary outcome was percent pain reduction at discharge and headache recurrence within 72 hours, with headache recurrence defined as receipt of neurology care via phone, clinic, or hospital encounter.
Patients received IV ketamine at a median dose of 0.25 mg/kg/hr for a median of 3 days.
Overall, the treatment was “safe and well tolerated,” Dr. Rosenthal said.
There were no serious adverse events and no cardiac side effects; 7% (five out of 68) stopped treatment due to side effects. The most common side effects were dizziness (23%), nausea (16%), blurred vision (12%), hallucinations (19%), cognitive fog (7%), vomiting (6%) and dysphoria (4%), worsening headache (4%), and paresthesia and cramping (1.5%).
‘Exciting Starting Point’
At baseline, pain scores were 8 (on a scale of 0-10) and progressively fell (improved) during treatment. Pain scores were 6 on day 1 and were 5 on day 2, with a slight rebound to 5 at discharge, although the pain reduction at discharge (vs baseline) remained statistically significant (P < .001).
“The median percent pain reduction after 3 days of ketamine was about 40%,” Dr. Rosenthal said.
He noted that on the first day of treatment, 16% of patients responded to treatment (with a > 50% reduction in their initial pain); this doubled to 33% on day 2 and increased to 44% at discharge.
In terms of recurrence, 38% had a recurrence within 1 month, “meaning two thirds did not,” Dr. Rosenthal noted. Median time to recurrence was 7 days. There were no recurrences within 72 hours.
The researchers also tried to tease out which patients might respond best to ketamine.
“Surprisingly,” there wasn’t a strong effect of most demographic variables such as age, sex, gender identity, chronic pain, psychiatric comorbidities, duration of headache, or prior interventions, Dr. Rosenthal noted.
“Interestingly,” he said, patients who were on two or more preventive medications had a 50% reduction in their pain at discharge compared with a 33% reduction in patients taking one or no preventive medication. It’s possible that more preventative medications may “prime” a patient’s response to ketamine, Dr. Rosenthal said.
She added that future randomized studies are needed to further assess IV ketamine for refractory headache in children, but these results are “an exciting starting point.”
‘Still an Unknown’
Seniha Nur Ozudogru, MD, assistant professor of clinical neurology at Penn Medicine in Philadelphia, echoed the need for further study.
The role of IV ketamine in refractory pediatric headache is “still an unknown,” said Dr. Ozudogru, who was not involved in the study.
She noted that currently, there is “no standard protocol for ketamine infusion, even for adults. Every institution has their own protocols, which makes it difficult.”
Dr. Ozudogru also wonders how “doable” in-hospital IV infusions over 3 days may be for children.
“Especially for chronic migraine patients, it can be really tricky to manage expectations in that even if they don’t respond and the headache doesn’t go away, they still may have to be discharged. That requires a specific approach and discussion with the patients,” Dr. Ozudogru said.
Intranasal ketamine is another potential option, she said, with a recent study suggesting that intranasal ketamine is an effective treatment for children hospitalized with refractory migraine.
“However, there is some concern about the potential of addiction and the side effects of hallucinations and what the main protocol will be, so this not a standard treatment and has to be studied further,” she said.
The study had no specific funding. Dr. Rosenthal and Dr. Ozudogru have no relevant disclosures.

Patients received IV ketamine at a median dose of 0.25 mg/kg/hr for a median of 3 days.
Overall, the treatment was “safe and well tolerated,” Dr. Rosenthal said.
There were no serious adverse events and no cardiac side effects; 7% (five out of 68) stopped treatment due to side effects. The most common side effects were dizziness (23%), nausea (16%), blurred vision (12%), hallucinations (19%), cognitive fog (7%), vomiting (6%) and dysphoria (4%), worsening headache (4%), and paresthesia and cramping (1.5%).
‘Exciting Starting Point’
At baseline, pain scores were 8 (on a scale of 0-10) and progressively fell (improved) during treatment. Pain scores were 6 on day 1 and were 5 on day 2, with a slight rebound to 5 at discharge, although the pain reduction at discharge (vs baseline) remained statistically significant (P < .001).
“The median percent pain reduction after 3 days of ketamine was about 40%,” Dr. Rosenthal said.
He noted that on the first day of treatment, 16% of patients responded to treatment (with a > 50% reduction in their initial pain); this doubled to 33% on day 2 and increased to 44% at discharge.
In terms of recurrence, 38% had a recurrence within 1 month, “meaning two thirds did not,” Dr. Rosenthal noted. Median time to recurrence was 7 days. There were no recurrences within 72 hours.
The researchers also tried to tease out which patients might respond best to ketamine.
“Surprisingly,” there wasn’t a strong effect of most demographic variables such as age, sex, gender identity, chronic pain, psychiatric comorbidities, duration of headache, or prior interventions, Dr. Rosenthal noted.
“Interestingly,” he said, patients who were on two or more preventive medications had a 50% reduction in their pain at discharge compared with a 33% reduction in patients taking one or no preventive medication. It’s possible that more preventative medications may “prime” a patient’s response to ketamine, Dr. Rosenthal said.
She added that future randomized studies are needed to further assess IV ketamine for refractory headache in children, but these results are “an exciting starting point.”
‘Still an Unknown’
Seniha Nur Ozudogru, MD, assistant professor of clinical neurology at Penn Medicine in Philadelphia, echoed the need for further study.
The role of IV ketamine in refractory pediatric headache is “still an unknown,” said Dr. Ozudogru, who was not involved in the study.
She noted that currently, there is “no standard protocol for ketamine infusion, even for adults. Every institution has their own protocols, which makes it difficult.”
Dr. Ozudogru also wonders how “doable” in-hospital IV infusions over 3 days may be for children.
“Especially for chronic migraine patients, it can be really tricky to manage expectations in that even if they don’t respond and the headache doesn’t go away, they still may have to be discharged. That requires a specific approach and discussion with the patients,” Dr. Ozudogru said.
Intranasal ketamine is another potential option, she said, with a recent study suggesting that intranasal ketamine is an effective treatment for children hospitalized with refractory migraine.
“However, there is some concern about the potential of addiction and the side effects of hallucinations and what the main protocol will be, so this not a standard treatment and has to be studied further,” she said.
The study had no specific funding. Dr. Rosenthal and Dr. Ozudogru have no relevant disclosures.

DENVER — , new research suggests. In a retrospective chart review, IV ketamine led to in a 50% reduction in pain at discharge, with “nearly two-thirds” of patients having no recurrence within 30 days, noted lead investigator Scott Rosenthal, MD, from the University of Colorado Anschutz Medical Campus, Aurora.
Dr. Rosenthal reported the findings at the 2024 annual meeting of the American Academy of Neurology.
Statistically Significant Pain Relief
“IV ketamine has shown benefit in nonheadache chronic pain syndromes and refractory mood disorders. Patients with refractory status migraines are often left with ongoing pain and dysfunction after failing typical interventions,” Dr. Rosenthal said.
“Ketamine has emerged as a potential treatment option in this population. However, there’s very little research on the efficacy and tolerability of it in general as well as the pediatric population,” he noted.
Dr. Rosenthal and colleagues took a look back at patients admitted to Children’s Hospital Colorado between 2019 and 2022 for treatment of severe refractory headache who were treated with continuous IV ketamine.
They analyzed 68 encounters of 41 unique patients aged 5-21 years (median age 16 years; 85% girls). Chronic migraine without aura made up 79% of cases.
On presentation, most patients had an exacerbation or ongoing worsening of pain for about 10 days, and all but two were taking a preventive medication. Nearly 70% had a comorbid psychiatric diagnosis such as anxiety or depression, and 60% had a comorbid chronic pain diagnosis separate from their headache diagnosis.
The primary outcome was percent pain reduction at discharge and headache recurrence within 72 hours, with headache recurrence defined as receipt of neurology care via phone, clinic, or hospital encounter.

First Long-Term Data on Atogepant for Migraine Prevention
DENVER —
The data show that 70% of patients treated with atogepant 60 mg daily achieved at least a 50% reduction in monthly migraine days at weeks 13-16 and this was maintained over 48 weeks of treatment.
“This is the first long-term study for assessing the safety and efficacy of a drug belonging to the gepant class, atogepant, used in the prevention of migraine in persons with episodic migraine who did not benefit from several previous preventive treatments or with chronic migraine,” said study investigator Cristina Tassorelli, MD, professor and chair of neurology, University of Pavia, Italy.
“It shows consistency of efficacy over 48 weeks and confirms the known safety profile of atogepant reported in randomized controlled trials, without detecting any new signal with the open-label use over 1 year,” Dr. Tassorelli said.
The results were reported at the 2024 annual meeting of the American Academy of Neurology by Sait Ashina, MD, with the Comprehensive Headache Center at Beth Israel Deaconess Medical Center in Boston.
Novel Longer-Term Data
The extension study includes more than 500 patients who completed the phase 3 PROGRESS or ELEVATE randomized placebo-controlled trials of atogepant 60 mg once daily for prevention of episodic or chronic migraine. It will run for 156 weeks.
Dr. Ashina reported safety and tolerability data at 52 weeks of treatment and efficacy data between 13 and 48 weeks of treatment. The mean duration of atogepant exposure was 496.5 days, and the mean number of migraine days at baseline was 14.5.
With atogepant, monthly migraine days improved on average by 8.5 days at weeks 13-16, and this was consistent over 48 weeks, Dr. Ashina reported. Similar improvements were observed for monthly headache days and monthly acute medication use days.
In addition, 70% of patients achieved a 50% or greater reduction in monthly migraine days at weeks 13-16, and this was consistent during the 48 weeks of open-label treatment.
Overall safety results were consistent with the known safety profile of atogepant. “A small percentage of subjects (< 6%) discontinue the treatment because of side effects,” Dr. Tassorelli said.
The most common treatment-emergent adverse events (≥ 5% of participants) were COVID-19 (28.7%), nasopharyngitis (10.9%), and constipation (8.2%).
As the first report of 1-year atogepant data, the results are “very encouraging” for patients and clinicians, Dr. Ashina said in wrapping up his presentation.
Important Advance, but Not Transformative
Reached for comment, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, noted that “[w]hile the anti-CGRP medications represent an important advancement in migraine treatment, the data suggests they have not necessarily transformed the landscape as dramatically as some may have expected.
“The efficacy of the anti-CGRP drugs appears to be generally similar to previous preventive and mostly genericized treatments, offering modest but meaningful improvements in migraine frequency and severity for many patients,” Dr. Lakhan said.
“In terms of safety, the anti-CGRPs do seem to have a somewhat cleaner profile compared to earlier migraine preventives, which is certainly a positive. However, the long-term data is still emerging, so the full safety picture is not yet clear,” Dr. Lakhan added.
“These medications are also associated with significantly higher overall healthcare costs compared to other treatment approaches. The substantial cost implications, both for patients and the healthcare system, deserve careful consideration as we assess their overall value and role in migraine care going forward,” Dr. Lakhan said.
Funding was provided by AbbVie. Several investigators have disclosed financial relationships with the company. Dr. Lakhan has no relevant disclosures.

Tension, Other Headache Types Robustly Linked to Attempted, Completed Suicide
DENVER – , results of a large study suggest.
The risk for suicide attempt was four times higher in people with trigeminal and autonomic cephalalgias (TAC), and the risk for completed suicide was double among those with posttraumatic headache compared with individuals with no headache.
The retrospective analysis included data on more than 100,000 headache patients from a Danish registry.
“The results suggest there’s a unique risk among headache patients for attempted and completed suicide,” lead investigator Holly Elser, MD, MPH, PhD, resident, Department of Neurology, University of Pennsylvania, Philadelphia, said at the 2024 annual meeting of the American Academy of Neurology, where the findings were presented. “This really underscores the potential importance of complementary psychiatric evaluation and treatment for individuals diagnosed with headache.”
Underestimated Problem
Headache disorders affect about half of working-age adults and are among the leading causes of productivity loss, absence from work, and disability.
Prior research suggests headache disorders often co-occur with psychiatric illness including depression, anxiety, posttraumatic stress disorder, and even attempted suicide.
However, previous studies that showed an increased risk for attempted suicide in patients with headache relied heavily on survey data and mostly focused on patients with migraine. There was little information on other headache types and on the risk for completed suicide.
Researchers used Danish registries to identify 64,057 patients with migraine, 40,160 with tension-type headache (TTH), 5743 with TAC, and 4253 with posttraumatic headache, all diagnosed from 1995 to 2019.
Some 5.8% of those with migraine, 6.3% with TAC, 7.2% with TTH, and 7.2% with posttraumatic headache, had a mood disorder (depression and anxiety combined) at baseline.
Those without a headache diagnosis were matched 5:1 to those with a headache diagnosis by sex and birth year.
Across all headache disorders, baseline prevalence of mood disorder was higher among those with headache versus population-matched controls. Dr. Elser emphasized that these are people diagnosed with a mood disorder in the inpatient, emergency department, or outpatient specialist clinic setting, “which means we are almost certainly underestimating the true burden of mood symptoms in our cohort,” she said.
Researchers identified attempted suicides using diagnostic codes. For completed suicide, they determined whether those who attempted suicide died within 30 days of the attempt.
For each headache type, investigators examined both the absolute and relative risk for attempted and completed suicides and estimated the risk at intervals of 5, 10, and 20 years after initial headache diagnosis.
Robust Link
The “power of this study is that we asked a simple, but important question, and answered it with simple, but appropriate, methodologic techniques,” Dr. Elser said.
The estimated risk differences (RDs) for attempted suicide were strongest for TAC and posttraumatic headache and for longer follow-ups. The RDs for completed suicide were largely the same but of a smaller magnitude and were “relatively less precise,” reflecting the “rarity of this outcome,” said Dr. Elser.
After adjusting for sex, age, education, income, comorbidities, and baseline medical and psychiatric diagnoses, researchers found the strongest association or attempted suicide was among those with TAC (adjusted hazard ratio [aHR], 4.25; 95% CI, 2.85-6.33).
“A hazard ratio of 4 is enormous” for this type of comparison, Dr. Elser noted.
For completed suicide, the strongest association was with posttraumatic headache (aHR, 2.19; 95% CI, 0.78-6.16).
The study revealed a robust association with attempted and completed suicide across all headache types, including TTH, noted Dr. Elser. The link between tension headaches and suicide “was the most striking finding to me because I think of that as sort of a benign and common headache disorder,” she said.
The was an observational study, so “it’s not clear whether headache is playing an etiological role in the relationship with suicide,” she said. “It’s possible there are common shared risk factors or confounders that explain the relationship in full or in part that aren’t accounted for in this study.”
Ask About Mood
The results underscore the need for psychiatric evaluations in patients with a headache disorder. “For me, this is just going to make me that much more likely to ask my patients about their mood when I see them in clinic,” Dr. Elser said.
After asking patients with headache about their mood and stress at home and at work, physicians should have a “low threshold to refer to a behavioral health provider,” she added.
Future research should aim to better understand the link between headache and suicide risk, with a focus on the mechanisms behind low- and high-risk subgroups, said Dr. Elser.
A limitation of the study was that headache diagnoses were based on inpatient, emergency department, and outpatient specialist visits but not on visits to primary care practitioners. The study didn’t include information on headache severity or frequency and included only people who sought treatment for their headaches.
Though it’s unlikely the results “are perfectly generalizable” with respect to other geographical or cultural contexts, “I don’t think this relationship is unique to Denmark based on the literature to date,” Dr. Elser said.
Commenting on the study, session co-chair Todd J. Schwedt, MD, professor of neurology, Mayo Clinic Arizona, Phoenix, and president-elect of the American Headache Society, noted that the study offers important findings “that demonstrate the enormous negative impact that headaches can exert.”
It’s “a strong reminder” that clinicians should assess the mental health of their patients with headaches and offer treatment when appropriate, he said.
The study received support from Aarhus University. No relevant conflicts of interest were reported.

After adjusting for sex, age, education, income, comorbidities, and baseline medical and psychiatric diagnoses, researchers found the strongest association or attempted suicide was among those with TAC (adjusted hazard ratio [aHR], 4.25; 95% CI, 2.85-6.33).
“A hazard ratio of 4 is enormous” for this type of comparison, Dr. Elser noted.
For completed suicide, the strongest association was with posttraumatic headache (aHR, 2.19; 95% CI, 0.78-6.16).
The study revealed a robust association with attempted and completed suicide across all headache types, including TTH, noted Dr. Elser. The link between tension headaches and suicide “was the most striking finding to me because I think of that as sort of a benign and common headache disorder,” she said.
The was an observational study, so “it’s not clear whether headache is playing an etiological role in the relationship with suicide,” she said. “It’s possible there are common shared risk factors or confounders that explain the relationship in full or in part that aren’t accounted for in this study.”
Ask About Mood
The results underscore the need for psychiatric evaluations in patients with a headache disorder. “For me, this is just going to make me that much more likely to ask my patients about their mood when I see them in clinic,” Dr. Elser said.
After asking patients with headache about their mood and stress at home and at work, physicians should have a “low threshold to refer to a behavioral health provider,” she added.
Future research should aim to better understand the link between headache and suicide risk, with a focus on the mechanisms behind low- and high-risk subgroups, said Dr. Elser.
A limitation of the study was that headache diagnoses were based on inpatient, emergency department, and outpatient specialist visits but not on visits to primary care practitioners. The study didn’t include information on headache severity or frequency and included only people who sought treatment for their headaches.
Though it’s unlikely the results “are perfectly generalizable” with respect to other geographical or cultural contexts, “I don’t think this relationship is unique to Denmark based on the literature to date,” Dr. Elser said.
Commenting on the study, session co-chair Todd J. Schwedt, MD, professor of neurology, Mayo Clinic Arizona, Phoenix, and president-elect of the American Headache Society, noted that the study offers important findings “that demonstrate the enormous negative impact that headaches can exert.”
It’s “a strong reminder” that clinicians should assess the mental health of their patients with headaches and offer treatment when appropriate, he said.
The study received support from Aarhus University. No relevant conflicts of interest were reported.

Commentary: Migraine and Cardiovascular Risk, April 2024
A recent study, published in the March 2024 issue of Sleep Medicine, identified shift work as one of the risk factors for headache and migraine. The researchers conducted a meta-analysis, including seven studies and involving 422,869 participants. The authors defined shift work as characterized by individuals or teams working consecutively to exceed the standard 8-hour day. They reported that the pooled analysis revealed a significant association between shift work and an increased risk for headache. Specifically, they determined that "individuals working night shifts had a 44% higher risk of developing headaches and a higher incidence of migraines." The authors stated that this association did not establish any causal relationship, and they suggested that future research should investigate the impact of genetics or health behaviors, which could be considered shared risk factors.
An article that had been published in 2019 in Headache included two case reports detailing the effects of shift work on patients with migraine. The authors of the case reports stated that "in the two cases presented, shift work appeared to be associated with chronification of migraine and higher headache-related disability, despite optimal headache management and good patient adherence."[1] They observed that "a switch to only day shifts promoted transition to an episodic, less disabling pattern of migraine."[1] These publications both support the idea that, while patients may have an underlying predisposition to migraine, certain lifestyle factors can play a role in exacerbating symptoms.
Erenumab, one of the relatively new therapies for migraine, was found to have a potential link to worsening hypertension. According to an article published in February in Headache: The Journal of Head and Face Pain, there has not been evidence of hypertension in preclinical models or clinical trials, yet postmarketing data suggest that erenumab may be associated with hypertension. The authors conducted an observational retrospective cohort study that included 335 patients who had been seen at a tertiary headache or neurology department. At baseline, 20.9% (70/335) of patients had a prior diagnosis of hypertension. The researchers observed that 23.3% (78/335) of the patients were found to have worsening hypertension, and 13 patients of the 225 who continued on erenumab experienced an improvement in their blood pressure. The authors noted that there was no association between worsening hypertension and preexisting hypertension, sex, body mass index, or age, but patients with atrial fibrillation were more likely to develop worsening hypertension (odds ratio 4.9; 95% CI 1.12-21.4; P = .035).
Consideration of a relationship between hypertension and anti-calcitonin gene–related peptide migraine (CGRP) therapies has been found in other studies as well. Results of a retrospective study conducted at the University Hospital of Modena, to explore the rate of hypertension among patients treated with anti-CGRP monoclonal antibodies, were published in April 2024 in Neurological Sciences (published online November 6, 2023). Those authors reported that no significant increase in blood pressure was detected overall, yet 5.7% of the patients developed a significant increase in their blood pressure.[2] Specifically, the researchers reported that patients with preexisting hypertension were more likely to have a significant increase in blood pressure.[2] The study authors of the Neurological Sciences publication suggested that patients with preexisting hypertension should be cautiously monitored for signs of hypertension. A more recent publication noted that "CGRP is involved in the regulation of vasomotor tone under physiologic and pathologic conditions, including hypertension," which could explain these findings. As the two studies noted different underlying risk factors for hypertension for patients taking anti-CGRP migraine therapies, it is important to monitor patients for signs of hypertension regardless of their underlying cardiovascular status.
Migraine was also noted to potentially be associated with an increased risk for cerebrovascular disease and stroke among women who have underlying cardiovascular disease risk factors. According to a cross-sectional analysis whose results were published in Mayo Clinic Proceedings in May 2023, women with migraine were significantly more likely to have severe hot flashes compared with women without migraine.[3] Additionally, the authors stated that migraine was associated with a diagnosis of hypertension.[3]
Results of a secondary data analysis of a subset of 1954 women in the Coronary Artery Risk Development in Young Adults (CARDIA) study were published in the April 2024 issue of Menopause. After adjustment for age, race, estrogen use, oophorectomy, and hysterectomy, women with histories of migraine and persistent vasomotor symptoms were found to have a greater risk for cerebrovascular disease (hazard ratio [HR] 2.25; 95% CI 1.15-4.38), and stroke (HR 3.15; 95% CI 1.35-7.34), compared with women without migraine histories and with minimal vasomotor symptoms. After adjustment for cerebrovascular disease risk factors, the associations between migraine/vasomotor symptoms and cerebrovascular disease were attenuated (HR 1.51; 95% CI 0.73-3.10), and associations between migraine/vasomotor symptoms and stroke were similarly attenuated (HR 1.70; 95% CI 0.66-4.38). The authors of this research article concluded that migraine and persistent vasomotor symptoms are jointly associated with greater risk for cerebrovascular disease and stroke, particularly for women who already have traditional risk factors for cerebrovascular disease.
This new research brings the importance of managing migraine risk factors and symptoms to the forefront. Patients who experience migraine may have a higher risk for cerebrovascular disease. Minimizing migraine risk factors could potentially help reduce this risk for cerebrovascular disease for some patients, and effectively treating migraines may also play a role in reducing the risk for cerebrovascular disease. Some migraine therapies could worsen cardiovascular disease for some patients, however — particularly patients who already have underlying risk factors. Therefore, it is crucial for physicians to approach migraine care with a comprehensive strategy to reduce risk factors, assess underlying disease, and monitor for comorbidities.

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.

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.

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.
