Migraine ICYMI

The age at which a patient develops migraine with aura may be an important factor in assessing stroke risk, according to a prospective cohort study published in Headache.

Patients who had onset of migraine with visual aura after age 50 years had an increased risk of ischemic stroke, compared with patients with no headache, the researchers found. Patients with longer exposure to migraine with visual aura – that is, onset before age 50 years – did not have significantly increased ischemic stroke risk, said X. Michelle Androulakis, MD, of the department of neurology at the University of South Carolina in Columbia, and her colleagues.

“Migraine, especially migraine with aura, is associated with increased risk of ischemic stroke,” but whether age of migraine onset affects the risk of cardiovascular disease has been unclear, the researchers said.

To examine the risk of ischemic stroke in migraineurs with and without aura with onset before and after age 50 years, the investigators conducted a post hoc analysis of data from the ongoing Atherosclerosis Risk in Communities (ARIC) study. The researchers adjusted for potential confounders, including diabetes, body mass index, hypertension, and hyperlipidemia.

In ARIC, participants completed a questionnaire about their migraine history at their third study visit (1993-1995) and were followed for ischemic stroke incidence over 20 years.

Of the 11,592 ARIC participants included in the analysis (mean age, 61 years; 76.5% white; and 55.3% female), 447 had migraine with aura, and 1,128 had migraine without aura. Onset of migraine with aura at age 50 years or older (average duration, 4.75 years) was associated with more than twofold greater risk of ischemic stroke, compared with no headache (multivariable adjusted hazard ratio = 2.17). Onset of migraine with aura before age 50 years (average duration, 28.17 years) was not significantly associated with stroke. A logistic regression model yielded consistent results.

In addition, patients with migraine without aura did not have an increased risk of stroke, regardless of the age of onset. The absolute risk for stroke in migraine with aura was 8.27%, and the absolute risk in migraine without aura was 4.25%.

“We found unexpected results suggesting that the onset of migraine with aura before age 50 is not associated with ischemic stroke. ... These results are specific to first-time ischemic stroke incidents that occurred in mid- to late life; therefore, it cannot be generalized to stroke in younger patients,” the authors wrote.

It could be that migraine with aura symptoms that start at a later age are a red flag for paradoxical emboli from a patent foramen ovale or microemboli, Dr. Androulakis and her colleagues noted. It also is possible that the degree of cortical spreading depression required to induce migraine with aura symptoms is different later in life versus earlier in life.

“This study underscores the importance of MA symptoms onset in evaluation of ischemic stroke risk in late life,” the researchers concluded.

The authors had no relevant conflicts of interest. ARIC has been funded by the National Heart, Lung, and Blood Institute.

One-hour treatment with external trigeminal nerve stimulation resulted in significant headache pain relief compared to sham stimulation and was well tolerated, according to a recent double-blind, randomized, sham-controlled study conducted across 3 headache centers in the United States. Adult patients who were experiencing an acute migraine attack, with or without aura, were recruited on site and randomly assigned 1:1 to receive either verum or sham external trigeminal nerve stimulation treatment for 1 hour. Pain intensity was scored using a visual analog scale. Researchers found:

• One hundred and six patients were randomized and included in the intention-to-treat analysis (verum: n=52; sham: n=54).
• The primary outcome measure was significantly more reduced in the verum group than in the sham group: −3.46 ± 2.32 vs −1.78 ± 1.89, or −59% vs −30%.
• With regards to migraine subgroups, there was a significant difference in pain reduction between verum and sham for “migraine without aura” attacks.
• For “migraine with aura” attacks, pain reduction was numerically greater for verum vs sham, but did not reach significance: mean visual analog scale reduction at 1 hour was −4.3 ± 1.8 for the verum group vs −2.6 ± 1.9 for the sham group.

Alcoholic beverages, especially red wine, are recognized as a migraine trigger factor by patients with migraine and have a substantial effect on alcohol consumption behavior, according to a recent study. Researchers conducted a cross‐sectional, web‐based, questionnaire study among 2197 patients with migraine from the well‐defined Leiden University MIgraine Neuro‐Analysis (LUMINA) study population. They assessed alcoholic beverage consumption and self‐reported trigger potential, reasons behind alcohol abstinence, and time between alcohol consumption and migraine attack onset. They found:

• Alcoholic beverages were reported as a trigger by 35.6% of participants with migraine.
• In addition, more than 25% of patients with migraine who had stopped consuming or never consumed alcoholic beverages did so because of presumed trigger effects.
• Wine, especially red wine (77.8% of participants), was recognized as the most common trigger among the alcoholic beverages.
• However, red wine consistently led to an attack in only 8.8% of participants.
• Time of onset was rapid (<3 hours) in one‐third of patients and almost 90% had an onset of less than 10 hours independent of beverage type.

Adolescents with migraine and healthy adolescents have similar inhibitory pain modulation capability despite having marked differences in pain sensitivity, according to a recent study. Although participants with a family history of migraine (Fam-His) were asymptomatic, they demonstrated alterations in pain processing, which may serve as markers for prediction of migraine development. In order to determine if inhibitory pain modulation occurs in youth as it does in adults, researchers performed a quantitative sensory testing investigation in adolescents with migraine (n=19). These patients were compared to healthy adolescents with (n=20) or without (n=29) Fam-His of migraine (eg, first degree relative with migraine). They found:

• In response to graded heat stimuli, Fam-His participants reported higher pain intensity ratings compared to migraine patients, who in turn, reported higher pain intensity ratings than the healthy controls.
• For heat- and pressure- conditioned pain modulation (CPM), there was no significant group difference in the magnitude of CPM responses.

CHICAGO—Child neurologists differ in their approach to diagnosing and managing posttraumatic headache, according to survey results presented at the 47th Annual Meeting of the Child Neurology Society.

For example, practice differs as to when posttraumatic headaches are considered persistent and when to recommend preventive therapy.

“As there are no established guidelines on management of posttraumatic headache, it is not surprising that diagnosis and management vary considerably,” said Rachel Pearson, MD, a child neurology resident at Children’s Hospital of Orange County in Orange, California, and colleagues. “Further studies are needed to define the best evidence-based practices for pediatric posttraumatic headache.”

Research indicates that about 7% of children ages 3 to 17 experience a significant head injury, and headache is the most common postconcussive symptom. Headache persists at three months in as much as 43% of cases, according to current studies. To better understand the current clinical practices of child neurologists in the diagnosis and treatment of posttraumatic headache, Dr. Pearson and colleagues sent all active, nonresident members of the Child Neurology Society a link to an online survey. The survey covered diagnosis, management, and return-to-play guidelines. Ninety-five members responded to the survey.

Persistence Threshold: Four Weeks or Three Months?

Although 39% of respondents reported that they always use ICHD diagnostic criteria to diagnose posttraumatic headache, and 31% sometimes use ICHD criteria, “only 19% of respondents correctly defined persistent posttraumatic headache per ICHD diagnostic criteria” as lasting more than three months, the researchers said. “The largest number of participants considered posttraumatic headache to be persistent at four weeks,” they said. “This may have implications for when prophylactic headache medications are considered.”

More than 90% recommend NSAIDs as abortive therapy. One-third consider starting preventive headache therapy within one month, and one-third between one and two months.

The most commonly used preventive medications are amitriptyline and nortriptyline (93.7%) and topiramate (71.6%). Amitriptyline and nortriptyline may be widely used because they “can also address other postconcussive symptoms, such as sleep or mood disturbance,” the investigators noted.

Treatment Options

In addition, 59% of providers use vitamins and supplements (eg, magnesium, riboflavin, melatonin, and CoQ10) as preventive treatments. “These are considered generally safe and have few adverse effects,” and “families may prefer these treatment options as they are perceived as ‘natural,’” Dr. Pearson and colleagues said. More than half of respondents use nonmedicinal therapies such as physical therapy, pain-focused cognitive behavioral therapy, and biofeedback.

Thirty-eight percent use injection-based therapies (eg, nerve blocks, botulinum toxin, and trigger point injections), and 14% of providers administer injections themselves.

One-third of respondents recommend cognitive and physical rest for one to three days, followed by a progressive return to activities, consistent with evidence-based recommendations. Approximately one-third advise patients to rest for seven to 14 days before returning to play.

“As a whole, these findings can guide additional research in this area and serve as a platform on which to base future randomized controlled trials,” said Dr. Pearson and colleagues.

Steven M. Baskin, PhD, a clinical psychologist at the New England Institute for Neurology and Headache in Stamford, Connecticut, recently answered the Migraine Resource Center’s questions about the benefits of behavioral therapy in the treatment of migraine and tension-type headache.
 

Alan M. Rapoport, MD: Could you please give a brief description of the 5 best modalities of behavioral therapy for migraine and tension-type headache? 
 

Steven M. Baskin, PhD: The most researched modalities that have a good evidence base for both migraine and tension-type headache (TTHA) are relaxation therapies that often combine abdominal breathing with some form of progressive relaxation, electromyography (EMG) biofeedback therapy where headache patients learn to decrease scalp and neck muscle tension utilizing muscular biofeedback, thermal biofeedback where migraine sufferers learn a way to warm their hands which often creates a low arousal state that may reduce brain hyperexcitability, and cognitive behavioral therapy (CBT) techniques to learn stress management. The combination of behavioral medicine techniques plus preventive pharmacological treatment has been showed to be more efficacious than either treatment alone. (Holroyd KA, et al. Effect of preventive (β blocker) treatment, behavioural migraine management, or their combination on outcomes of optimised acute treatment in frequent migraine: randomised controlled trial. BMJ. 2010;1-12)

CBT to treat insomnia has also been shown to reverse many chronic migraine sufferers back to episodic migraine. (Smitherman TA, et al. Cognitive-Behavioral Therapy for Insomnia to Reduce Chronic Migraine: A Sequential Bayesian Analysis. Headache 2018;58:1052-1059)
 

Dr. Rapoport: How do you identify a patient who may benefit from behavioral therapy over acute medication, and what is the first step that you suggest?
 

Dr. Baskin: Behavioral therapies for migraine management are typically preventive therapies that can and should be combined with medications to control acute attacks. There are behavioral principles that can maximize adherence to abortive agents in order to optimize acute care.
 

Dr. Rapoport: Which tends to work the best for migraine?
 

Dr. Baskin: What works best is to first do a good behavioral assessment of the frequency, duration, intensity, and disability level of their headaches as well as current stress levels, history, and adherence to drug and nondrug therapies, and psychiatric comorbidities. A program should then be developed that includes some combination of pharmacological and behavioral interventions to address these issues. It is important to increase self-efficacy: patients’ belief in the ability to control the headache, belief in the ability to manage emotional reactivity to pain, and belief that they can achieve functionality in the presence of a significant headache disorder.
 

Dr. Rapoport: Who should not have biofeedback therapy?
 

Dr. Baskin: Biofeedback has shown to be effective in treating migraine and TTHA. It has not been shown to be effective in treating trigeminal autonomic cephalgias (TACs) such as cluster headache. Like pharmacological therapies, it is less effective in chronic migraine that is daily and constant. A patient with severe psychiatric disorder should be treated for their psychiatric disorder before beginning biofeedback therapy.
 

Dr. Rapoport: Some doctors see patients twice per week for several months. What is your typical routine for behavioral therapy?
 

Dr. Baskin: We have a variety of programs. For complicated patients, we tend to see them weekly and have a very systematic program of biofeedback and CBT for approximately 12 to 15 sessions. This may include treating psychiatric comorbidities. We see many other patients for 1 or 2 sessions of biofeedback to try to effect physiological learning and for 1 or 2 sessions of CBT to help them manage stressors and learn coping skills that they can use to help manage migraines and life stress.
 

Dr. Rapoport: Does behavioral medicine work best in conjunction with preventive medications, or on its own?

Dr. Baskin: Many patients do well with a behavioral treatment as a preventive therapy and a pharmacologic agent to optimize acute care. I believe that many patients with higher frequency migraine with psychological issues or ongoing stressors do best with a combination of preventive pharmacologic therapy and behavior therapy. Any migraine patient with sleep issues should learn CBT for insomnia. 

Dr. Rapoport: Is there evidence that suggests behavioral therapy can help patients at various ages manage their migraines?

Dr. Baskin: There is both adult and child data on behavioral therapy for migraine.  An excellent study was done in children and adolescents by Powers et al. It showed that adding 10 sessions of CBT to preventive amitriptyline therapy, compared to adding headache education, significantly reduced the number of headache days, level of disability, and kids with a better than 50% decrease in days of headache compared to amitriptyline, plus headache education control in chronic migraine patients.  (Powers SW et al. Cognitive Behavioral Therapy Plus Amitriptyline for Chronic Migraine in Children and Adolescents: A Randomized Clinical Trial. JAMA 2013;310(24):2622-2630)

Dr. Rapoport: A recent MedPage Today article noted that “anxiety may complicate migraine more than depression with greater long-term persistence, greater headache-related disability, and reduced satisfaction with acute therapies.” Could you please elaborate on why this may be the case? 

Dr. Baskin: Anxiety disorders are often based on feeling threat. They are always associated with avoidance behaviors. Headache sufferers with significant anxiety tend to overestimate the probability of danger (migraine) and perceive it as more unmanageable and threatening than objective reality. They are often very sensitive to medication side effects and benign somatic sensations. They sometimes take medications pre-emptively, because of their fear of getting a migraine, which may lead to medication misuse or overuse. The lifetime prevalence of anxiety disorders in migraineurs (ranging from 51-58%) is almost twice that of major depression.

Steven M. Baskin, PhD, a clinical psychologist at the New England Institute for Neurology and Headache in Stamford, Connecticut, recently answered the Migraine Resource Center’s questions about the benefits of behavioral therapy in the treatment of migraine and tension-type headache.
 

Alan M. Rapoport, MD: Could you please give a brief description of the 5 best modalities of behavioral therapy for migraine and tension-type headache? 
 

Steven M. Baskin, PhD: The most researched modalities that have a good evidence base for both migraine and tension-type headache (TTHA) are relaxation therapies that often combine abdominal breathing with some form of progressive relaxation, electromyography (EMG) biofeedback therapy where headache patients learn to decrease scalp and neck muscle tension utilizing muscular biofeedback, thermal biofeedback where migraine sufferers learn a way to warm their hands which often creates a low arousal state that may reduce brain hyperexcitability, and cognitive behavioral therapy (CBT) techniques to learn stress management. The combination of behavioral medicine techniques plus preventive pharmacological treatment has been showed to be more efficacious than either treatment alone. (Holroyd KA, et al.

In order to provide healthcare professionals with updated guidance in the use of novel preventive and acute treatments for migraine in adults, a recent position statement released by the American Headache Society updates prior recommendations and outlines the indications for initiating, continuing, combining, and switching preventive and acute treatments. Input was sought from health insurance providers, employers, pharmacy benefit service companies, device manufacturers, pharmaceutical and biotechnology companies, patients, and patient advocates. In addition, expert clinicians and researchers in the field of headache medicine from across North America and the European Union provided input and feedback.

The principles of pharmacologic preventive treatment of migraine with oral treatments have been as follows:

• Use evidence‐based treatments when possible and appropriate.
• Start with a low dose and titrate slowly; newer injectable treatments may work faster and may not need titration.
• Reach a therapeutic dose if possible.
• Allow for an adequate treatment trial duration.
• Establish expectations of therapeutic response and adverse events and maximize adherence.

The principles of acute treatment include:

• Use evidence‐based treatments when possible and appropriate.
• Treat early after the onset of a migraine attack.
• Choose a non-oral route of administration for selected patients.
• Account for tolerability and safety issues.
• Consider self‐administered rescue treatments.
• Avoid overuse of acute medications.

Migraine with aura was associated with increased risk of incident atrial fibrillation (AF), according to a recent study, which may potentially lead to ischemic strokes. In the Atherosclerosis Risk in Communities (ARIC) study, participants were interviewed for migraine history from 1993 through 1995 and were followed for incident AF through 2013. AF was adjudicated using electrocardiograms (ECGs), discharge codes, and death certificates. Multivariable Cox proportional hazards models were used to study the relation between migraine and its subtypes with incident AF, compared with controls without headaches. Researchers found:

• Of 11,939 participants assessed for headache and without prior AF or stroke, 426 reported migraine with visual aura, 1090 migraine without visual aura, 1018 non-migraine headache, and 9405 no headache.
• Over a 20-year follow-up period, incident AF was noted in 232 (15%) of 1516 with migraine and 1623 (17%) of 9405 without headache.
• After adjustment for multiple confounders, migraine with visual aura was associated with increased risk of AF compared to no headache as well as when compared to migraine without visual aura.

Women with active migraine have a lower risk of developing type 2 diabetes (T2D), according to a recent study, and a decrease in active migraine prevalence prior to diabetes diagnosis. Researchers used data from a prospective population-based study initiated in 1990 on a cohort of women born between 1925 and 1950. From eligible women in the study, researchers included those who completed a 2002 follow-up questionnaire with information available on migraine. They then excluded prevalent cases of T2D, leaving a final sample of women who were followed up between 2004 and 2014. All potential occurrences of T2D were identified through a drug reimbursement database. They found:

• From the 98,995 women in the study, 76,403 women completed the 2002 follow-up survey.
• Of these, 2156 were excluded because they had T2D, leaving 74,247 women.
• During 10 years of follow-up, 2372 incident T2D cases occurred.
• A lower risk of T2D was observed for women with active migraine compared with women with no migraine history (univariate hazard ratio, 0.80, multivariable-adjusted hazard ratio, 0.7).

Changes in speech occurred in almost half of individuals experiencing migraine attacks who were evaluated in a recent prospective, longitudinal, observational study. Participants provided speech samples 3 times per day using a speech elicitation tool included within a mobile app. Six complementary speech features that capture articulation and prosody were extracted from speech samples. Participants with migraine maintained a daily headache diary using the same app. A total of 56,767 speech samples were collected, including 43,102 from 15 individuals with migraine and 13,665 from matched healthy controls. They found:

• Significant group-level differences in speech features were identified between those with migraine and healthy controls and within the migraine group during the pre-attack vs attack vs interictal periods.
• Most consistently, speech changes occurred in the speaking rate, articulation rate and precision, and phonatory duration.
• Within-subject analysis revealed that 7 of 15 individuals with migraine showed significant change in at least 1 speech feature when comparing the migraine attack vs interictal phase and 4 showed similar changes when comparing the pre-attack vs interictal phases.
