Nearly 20% of migraineurs use opioids for migraine
PHILADELPHIA – People with 4 or more migraine headache days per month are more likely to use opioids, compared with people with fewer migraine headache days per month, researchers said. Opioid use for migraine “remains alarmingly high,” the investigators said at the annual meeting of the American Headache Society.
Although opioid use for the treatment of migraine typically is discouraged, studies indicate that it is common. Evidence suggests that opioids may increase the risk of progression from episodic to chronic migraine.
To evaluate opioid use in people with migraine, Sait Ashina, MD, of Harvard Medical School and Beth Israel Deaconess Medical Center in Boston, and the research colleagues analyzed data from 21,143 people with migraine who participated in the OVERCOME (Observational Survey of the Epidemiology, Treatment and Care of Migraine), a Web-based study of a representative U.S. sample. OVERCOME enrolled participants in the fall of 2018.
The researchers classified self-reported opioid use for migraine as current use in the past 12 months, former use, or never. Participants had a mean age of 42 years, and 74% were female. The researchers used a multivariable logistic regression model adjusted for age and sex in their analyses.
“Strikingly, we were able to find 19% of people with migraine were reporting current use of opioids,” Dr. Ashina said.
Among 12,299 patients with 0-3 migraine headache days per month, 59% were never, 26% former, and 15% current users of opioids for migraine. Among 8,844 patients with 4 or more migraine headache days per month, 44.9% were never, 31.2% former, and 23.9% current users of opioids for migraine.
There was an increased likelihood of opioid use for migraine in people with pain comorbidities such as back pain, neck pain, and fibromyalgia and in people with anxiety and depression.
Approximately 30%-40% of those who used opioids for migraine were using strong opioids, as defined by the World Health Organization, Dr. Ashina noted. Preliminary analyses indicate that patients tended to receive opioids in a primary care setting, he said.
Eli Lilly funded the OVERCOME study. Dr. Ashina has consulted for Novartis, Amgen, Promius, Supernus, Satsuma, and Allergan. He is on the Editorial Advisory Board for Neurology Reviews.

EXPERT ANALYSIS FROM AHS 2019
A plurality of migraineurs seeks care from primary care physicians
PHILADELPHIA – according to an investigation presented at the annual meeting of the American Headache Society.
The largest group of these patients consults primary care physicians. The acute and preventive migraine treatment that these patients receive vary according to the type of provider that they see. Nevertheless, treatment is generally suboptimal, compared with the standards of current guidelines, said the investigators.
Migraine is underdiagnosed and undertreated, said Dawn C. Buse, PhD, clinical professor of neurology at Albert Einstein College of Medicine, New York, and colleagues. Recent changes in health care policy and the expanded array of treatments for migraine warrant an investigation of the current state of migraine care, they added. They examined survey data to understand where patients with migraine in the United States seek care, which characteristics are associated with seeking care in the previous 12 months, and which treatments are prescribed.
Dr. Buse and colleagues analyzed data from the OVERCOME (Observational Survey of the Epidemiology, Treatment, and Care of Migraine) study. These data were obtained in 2018 using a Web-based survey of a representative U.S. sample of 21,143 patients with migraine. The investigators focused on care seeking and medication use in a subsample of 8,844 patients with 4 or more migraine headache days per month to better understand those with the greatest care needs.
The mean age of this subsample was 42.0 years. Approximately 78% of participants were female, and 74.8% were white. In the preceding 12 months, 61.1% of the patients sought care for migraine; 38.3% sought care from more than two types of provider. Provider types included primary care physicians (45.5%), neurologists (20.2%), emergency medicine clinicians (19.2%), urgent care providers (14.4%), pain specialists (12.8%), headache specialists (12.0%), and retail (nonurgent) clinics (10.4%).
Dr. Buse and colleagues found that sociodemographic factors such as age, sex, education, income, and health insurance type influenced participants’ likelihood of seeking care. Seeking care was positively associated with the number of headache days, pain severity, allodynia, aura, and prodrome. When the researchers examined migraine characteristics, they found that nausea and vomiting (68.8%) was more likely to prompt a patient to seek care, compared with phonophobia and photophobia (64.3%). Participants who sought care from a headache specialist (55.0%) or a neurologist (50.1%) were most likely to be using migraine preventive medication. More than 20% of migraineurs seeking care from primary care, urgent care, or retail clinic professionals were undiagnosed.
Primary care doctors were most likely to prescribe triptans, followed by opioids and preventive medications. Neurologists and headache specialists were most likely to prescribe preventive medications and unlikely to prescribe opioids.
Eli Lilly funds the OVERCOME study. Dr. Buse consults for Lilly on this study, but she and her coauthors who do not work in the industry did not receive any funding for any work related to writing, publishing, or presenting any abstracts, posters, platforms, or manuscripts.

Alzheimer’s disease raises risk for recurrent seizures
LOS ANGELES – Seizures are not uncommon among patients with Alzheimer’s disease – particularly as patients live longer with the disease – and are often associated with worse cognitive and functional performance, according to research findings presented at the Alzheimer’s Association International Conference.
Jonathan Vöglein, MD, of the German Center for Neurodegenerative Diseases and Ludwig-Maximilian University in Munich presented results from a cohort of 9,127 patients with Alzheimer’s disease (AD), of whom 287 had experienced a seizure, and more than 10,000 non-AD control subjects recruited at clinics during 2005-2016.
Dr. Vöglein and colleagues found that seizure risk increased with duration of disease, from 1.5% of patients at 4.8 years with the disease to 5.4% at 11 years, with likelihood of a seizure increasing steadily over time.
Moreover, 70% of AD patients who experienced a seizure had a second one within 7.5 months. People who had seizures fared worse on cognitive and functional tests: a mean 16.6 on the Mini Mental State Examination, compared with 19.6 for patients without seizures. On a severity rating scale, the Clinical Dementia Rating Sum of Boxes, patients with seizures also fared worse, with scores of 9.3, compared with 6.8 for patients without seizures (P less than .0001 for all, with results adjusted for age and disease duration).
“The data of our study show that there’s an association of seizures with worse cognitive and functional performance,” Dr. Vöglein said in an interview.
“It’s important for clinicians to know that Alzheimer’s patients are at an increased risk for seizures,” Dr. Vöglein said. “In my clinical care experience, seizures are rarely the main complaint of patients with Alzheimer’s disease.” Detailed interviews with the patient and a proxy are important, he added, because patients with Alzheimer’s disease may not always remember events that could be a seizure.
Dr. Vöglein noted that, to his knowledge, there are no reliable data showing that treating seizures with antiepileptic drugs slows cognitive decline. “The results of our study suggest that an antiepileptic treatment after a first seizure in patients with Alzheimer’s dementia may be considered,” he said.
Also at the conference, researcher Ruby Castilla-Puentes, MD, DrPH, of Janssen Pharmaceuticals in Hopewell, N.J., along with Miguel Habeych, MD, MPH, of the University of Cincinnati presented findings on dementia and seizure risk from a large U.S. national managed care database of nearly 3 million people aged 60 years and older, of whom 56% were women.
The researchers analyzed this cohort during 2005-2014 and identified 80,000 people (2.8% of the cohort) as having any dementia diagnosis. The overall incidence of new-onset seizures in patients with dementia was 12.3% per year. In general, all subtypes of seizures and epileptic disorders (partial, generalized, or undifferentiated) occurred more frequently in patients with dementia, compared against patients without dementia (P less than .0001).
People with dementia had more than six times greater risk for experiencing recurring epileptic seizures than did people without dementia (95% confidence interval, 4.4-9.5). They were at six times higher risk for partial seizures (95% CI, 5.5-6.6); fivefold higher risk for generalized (95% CI, 4.9-5.5) and undifferentiated epilepsy (95% CI, 4.8-5.2); and 4.75 times higher risk for generalized seizures (95% CI, 4.5-5.0) and partial epilepsy (95% CI, 4.4-5.1).
“Although there are limitations with the use of administrative claims databases to calculate incidence rates, this analysis suggests that patients of 60 years of age or older have higher risks of new-onset seizures associated with a dementia diagnosis,” Dr. Castilla-Puentes commented.
The findings, she said, reinforce the need for clinicians to monitor for seizures to ensure that patients with dementia receive appropriate treatment.
Dr. Vöglein disclosed no financial conflicts of interest. Dr. Castilla-Puentes disclosed being an employee of Janssen, which funded her study.

Changes in sleep-wake timing accompany cerebral glucose hypometabolism and cognitive function
LOS ANGELES – Dysregulated sleep-wake cycles may be linked to cerebral glucose hypometabolism and subtle cognitive changes, both of which are early signs of Alzheimer’s disease–like neurodegeneration, according to a 2-year study of older Korean adults.
The association was particularly strong in subjects who experienced delayed acrophase, the peak of the normal sleep-wake cycle, So-Yeon Jeon, MD, said at the Alzheimer’s Association International Conference. It’s not yet clear whether the changes are a risk factor for dementia or a prodromal sign of neurodegeneration, but even without full elucidation, the findings could have value as a signal of impending neurodegeneration, said Dr. Jeon of Seoul (South Korea) National University.
“Our findings suggest that delayed acrophase may be used as a predictor for the progression of Alzheimer’s-type neurodegeneration and cognitive decline in the near future in old individuals with diverse cognitive status,” she said. “But the relationship between circadian phases and neurodegeneration is complex and not yet well understood.”
The 24-month study comprised 215 elderly adults enrolled in the Korean Brain Aging Study for the Early Diagnosis and Prediction of Alzheimer’s Disease (KBASE). They were a mean of 70 years old at baseline; 143 were cognitively normal, 40 had mild cognitive impairment, and 32 had Alzheimer’s dementia. Both at baseline and 2 years, everyone underwent a comprehensive neuropsychological assessment, amyloid PET brain imaging with Pittsburgh compound B, and an [18F]-fluorodeoxyglucose PET scan to determine brain glucose metabolic rate.
Before each assessment, the investigators measured sleep and circadian rhythms with 8 days of actigraphy. This assessed sleep variables (total sleep time, sleep latency, sleep efficiency, and wakefulness after sleep); rest-activity rhythm variables (midline estimated statistic of rhythm, amplitude, and acrophase), and some nonparametric values including interdaily stability, intradaily variability, and relative amplitude of sleep cycles. Subjects also completed sleep diaries during these periods.
The study’s main outcomes were 2-year changes in the Mini Mental State Exam (MMSE) score and in Alzheimer’s imaging biomarkers, including glucose metabolism and amyloid deposition. All analyses controlled for age, sex, Clinical Dementia Rating score, apolipoprotein E allele status, and baseline cognition.
At baseline, lower total sleep time was significantly associated with hypometabolism in areas associated with Alzheimer’s pathology as well as lower mean MMSE scores. Circadian variables showed no significant associations with these characteristics. However, the relative amplitude of circadian rhythm was significantly associated with hypometabolism and with lower MMSE score. There were no associations with brain amyloid load.
At 2 years, acrophase was associated with declines in cerebral glucose metabolism and further changes in the MMSE, even after the researchers controlled for the potential confounders. Delayed acrophase, although not associated with either metabolic rate or cognition at baseline, did significantly influence both at 2 years, suggesting a rapidly eroding clinical picture.
“Neurodegeneration over 2 years means the disease is progressing rapidly and subjects are likely to have tauopathies or other proteinopathy,” Dr. Jeon said. “These pathologies may either be resulting in delayed acrophase followed by neurodegeneration, or they may be prodromal symptoms of impending neurodegeneration. Whether they are early symptoms or early risk factors is not currently known, however. Two years is too short of a follow-up to determine these questions.”
Dr. Jeon had no financial declarations.

Delayed acrophase, although not associated with either metabolic rate or cognition at baseline, did significantly influence both at 2 years, suggesting a rapidly eroding clinical picture.
“Neurodegeneration over 2 years means the disease is progressing rapidly and subjects are likely to have tauopathies or other proteinopathy,” Dr. Jeon said. “These pathologies may either be resulting in delayed acrophase followed by neurodegeneration, or they may be prodromal symptoms of impending neurodegeneration. Whether they are early symptoms or early risk factors is not currently known, however. Two years is too short of a follow-up to determine these questions.”

LOS ANGELES – Dysregulated sleep-wake cycles may be linked to cerebral glucose hypometabolism and subtle cognitive changes, both of which are early signs of Alzheimer’s disease–like neurodegeneration, according to a 2-year study of older Korean adults.
The association was particularly strong in subjects who experienced delayed acrophase, the peak of the normal sleep-wake cycle, So-Yeon Jeon, MD, said at the Alzheimer’s Association International Conference. It’s not yet clear whether the changes are a risk factor for dementia or a prodromal sign of neurodegeneration, but even without full elucidation, the findings could have value as a signal of impending neurodegeneration, said Dr. Jeon of Seoul (South Korea) National University.
“Our findings suggest that delayed acrophase may be used as a predictor for the progression of Alzheimer’s-type neurodegeneration and cognitive decline in the near future in old individuals with diverse cognitive status,” she said. “But the relationship between circadian phases and neurodegeneration is complex and not yet well understood.”
The 24-month study comprised 215 elderly adults enrolled in the Korean Brain Aging Study for the Early Diagnosis and Prediction of Alzheimer’s Disease (KBASE). They were a mean of 70 years old at baseline; 143 were cognitively normal, 40 had mild cognitive impairment, and 32 had Alzheimer’s dementia. Both at baseline and 2 years, everyone underwent a comprehensive neuropsychological assessment, amyloid PET brain imaging with Pittsburgh compound B, and an [18F]-fluorodeoxyglucose PET scan to determine brain glucose metabolic rate.
Before each assessment, the investigators measured sleep and circadian rhythms with 8 days of actigraphy. This assessed sleep variables (total sleep time, sleep latency, sleep efficiency, and wakefulness after sleep); rest-activity rhythm variables (midline estimated statistic of rhythm, amplitude, and acrophase), and some nonparametric values including interdaily stability, intradaily variability, and relative amplitude of sleep cycles. Subjects also completed sleep diaries during these periods.
The study’s main outcomes were 2-year changes in the Mini Mental State Exam (MMSE) score and in Alzheimer’s imaging biomarkers, including glucose metabolism and amyloid deposition. All analyses controlled for age, sex, Clinical Dementia Rating score, apolipoprotein E allele status, and baseline cognition.
At baseline, lower total sleep time was significantly associated with hypometabolism in areas associated with Alzheimer’s pathology as well as lower mean MMSE scores. Circadian variables showed no significant associations with these characteristics. However, the relative amplitude of circadian rhythm was significantly associated with hypometabolism and with lower MMSE score. There were no associations with brain amyloid load.
At 2 years, acrophase was associated with declines in cerebral glucose metabolism and further changes in the MMSE, even after the researchers controlled for the potential confounders. Delayed acrophase, although not associated with either metabolic rate or cognition at baseline, did significantly influence both at 2 years, suggesting a rapidly eroding clinical picture.

Obesity tied to relapse in young patients with multiple sclerosis
, results of a recent large, single-center study show. The rate of switching to second-line disease-modifying therapy was consequently about 50% higher among the obese children in the study, which included a total of 453 pediatric patients.
The link between obesity and treatment response suggests that the management of these younger patients with MS could be improved through weight loss or body mass index (BMI)-adjusted dosing, according to Peter Huppke, MD, of Georg August University in Göttingen, Germany, and co-investigators.
“The findings do not indicate that obesity promotes greater disease activity, but pharmacokinetic factors are more likely associated with treatment response,” Dr. Huppke and co-authors said in a report on their study, which was published online ahead of print July 15 in JAMA Neurology.
This is believed to be the first-ever study to find an association between BMI and treatment response in pediatric patients with MS, according to the authors, who said they also confirmed a link between obesity and MS.
Specifically, obesity increased MS susceptibility by two-fold as compared with healthy controls, a finding that they said adds to a small but growing body of evidence that high BMI is associated with increased risk of the disease in these younger individuals.
This retrospective study included 453 pediatric patients with MS treated at the Center for MS in Childhood and Adolescence in Göttingen, Germany between 1990 and 2016. About two-thirds were female and the mean age at MS diagnosis was about 14 years.
Of those patients, 126 (27.8%) were classified as obese based on a BMI greater than the 90th percentile, according to the report.
Dr. Huppke and co-investigators found that high BMI was linked to a significantly increased odds of pediatric MS, with odds ratios of 2.19 (95% CI, 1.5-3.1; P < 0.001) in girls and 2.14 (95% CI, 1.3-3.5; P = 0.003) in boys.
A total of 277 of these pediatric patients received a first-line disease-modifying therapy for 6 months or longer, including 249 treated with interferon beta and 51 treated with glatiramer.
Relapses were more common in obese patients, according to the report. with an annualized relapse rate of 1.29, compared to just 0.72 for those who were not overweight (P < 0.001).
Consequently, likelihood of receiving a second-line treatment was about 1.5 times higher in the obese or extremely obese patients, investigators said.
“A healthy weight may potentially optimize treatment outcomes and reduce disease-related burden and health care costs,” they concluded in the report, adding that BMI-adjusted dosing may “increase the value” of first-line disease-modifying therapies.
Dr. Huppke reported disclosures related to Bayer Health Care, Merck Serono, and Novartis not associated with the current study.

Can mindfulness-based cognitive therapy treat migraine?
PHILADELPHIA – , according to randomized clinical trial results.
“The fact that people can improve how they live their daily life even with the same amount of headache days and the same pain intensity is remarkable,” said study investigator Elizabeth K. Seng, PhD, associate professor of psychology at Yeshiva University and research associate professor of neurology at Albert Einstein College of Medicine, both in New York. “I think this gives us a little bit of a clue about when to use these kinds of treatments.”
Dr. Seng presented findings from the phase 2b pilot trial at the annual meeting of the American Headache Society.
To study the efficacy of mindfulness-based cognitive therapy for migraine, Dr. Seng and her research colleagues recruited participants with migraine in the New York City area between 2015 and 2018. In all, 60 patients were randomized to receive 8 weekly individual 75-minute mindfulness-based cognitive therapy for migraine sessions or 8 weeks on a wait list with treatment as usual.
Primary outcomes were Month 0 to Month 4 changes in perceived disability, measured using the Henry Ford Disability Inventory (HDI) and functional disability measured using the Migraine Disability Assessment Scale (MIDAS). Secondary outcomes included changes in headache days per 30 days and headache pain intensity.
Participants had a mean age of about 40 years, about 92% were women, and approximately half of the patients had chronic migraine. Participants had an average baseline HDI of 51.4, and 83.3% had MIDAS scores indicating severe disability. Patients averaged 10.4 headache attack days per month, and mean headache attack severity on a 0-10 scale was 6.2. Attrition did not significantly differ between the mindfulness-based cognitive therapy and control groups.
Patients who received mindfulness-based cognitive therapy for migraine experienced an approximately 15-point reduction on the HDI scale at 4 months, whereas wait-listed patients did not experience much of a change, Dr. Seng said. The difference between groups was statistically significant.
At 4 months, a smaller proportion of patients in the mindfulness-based cognitive therapy group had a MIDAS score of 21 or greater, but the difference between groups was not statistically significant. The data indicate a large effect that the study was underpowered to detect, Dr. Seng said.
A planned subgroup analysis found that mindfulness-based cognitive therapy produced changes in disability that were greater in patients with episodic migraine, compared with patients with chronic migraine. A reduction in MIDAS scores was statistically significant among patients with episodic migraine.
During the trial, one patient experienced increased headache frequency and intensity and changed their preventive treatment regimen, which investigators considered unrelated to mindfulness-based cognitive therapy. In addition, one patient experienced flooding – a vivid recollection of a traumatic event – which is an expected effect of meditation and relaxation therapy, Dr. Seng said. The patient completed the study and was satisfied with the mindfulness-based cognitive therapy training, she said.
“Preliminary evidence suggests that mindfulness-based cognitive therapy could be recommended to reduce headache-related disability in people with episodic migraine or people who have some kind of effective prevention on board, but they are still experiencing high levels of disability,” Dr. Seng said.
Although flooding may occur in patients with a trauma history who use meditation and relaxation, the techniques still may be useful, Dr. Seng said. “In the VA setting, we use meditation and relaxation all the time. But it helps to forewarn patients that they might experience distressful flooding and [to provide] techniques that they can use to reduce the impact of that.”

EXPERT ANALYSIS FROM AHS 2019
Opioid use is common among migraineurs who take prescription medication
PHILADELPHIA – , according to a study presented at the annual meeting of the American Headache Society. Opioid use among migraineurs is associated with indicators of poor health, such as high body mass index (BMI), high pain scores, and cardiovascular comorbidities. Some variables associated with opioid use are modifiable.
Medical associations do not recommend opioid use for migraine because it may increase the risks of dependence, suboptimal outcomes, and new-onset chronic migraine. Richard B. Lipton, MD, Edwin S. Lowe Chair in neurology at Albert Einstein College of Medicine in Bronx, New York, and colleagues analyzed data from the Chronic Migraine Epidemiology and Outcomes (CaMEO) study to identify variables associated with opioid use among patients who treat their headaches with acute prescription medications.
Using a web panel that was demographically similar to the U.S. population, CaMEO identified people with migraine, based on the criteria of the International Classification of Headache Disorders, 3rd Edition. Dr. Lipton and colleagues examined participants who reported currently using or having on hand acute prescription pain medication to treat headaches. The researchers compared the features (e.g., demographics, attack frequency, treatment choices, headache-related disability, and comorbidity) of self-reported opioid users with those of nonusers. They created nested, multivariable, binary logistic regression models to evaluate opioid use or nonuse as the outcome. Dr. Lipton and colleagues entered covariates in blocks (i.e., sociodemographics, headache and respondent characteristics, psychiatric comorbidities, emergency facility use for headache in the preceding 6 months, and one or more cardiovascular [CV] comorbidity) and removed nonsignificant sociodemographic variables from the model.
The researchers identified 2,388 respondents with migraine who currently used acute prescription medications for headache. Of this group, 867 (36.3%) used opioids. Compared with opioid nonusers, opioid users had significant increases in monthly headache days; frequency of emergency care use for headache within the past 6 months; medication overuse frequency; presence of allodynia, depression, anxiety, and CV comorbidity; Total Pain Index (TPI) scores; and diabetes diagnoses.
Factors significantly associated with opioid use included male sex (odds ratio [OR], 1.74); increasing body mass index BMI (OR, 1.02); allodynia (OR, 1.39); increasing monthly headache day frequency; increasing TPI scores excluding the head, face, and neck (1.32); anxiety (OR, 1.37); depression (OR, 1.50); one or more CV comorbidity (OR, 1.56); and emergency facility use for headache in the past 6 months (OR, 1.73). The OR of opioid use was 1.37 in patients with a monthly headache frequency of 10-14 days and 1.62 in patients with a frequency of 15 or more days, compared with patients with a monthly headache frequency of 0-4 days.
Receiving a diagnosis of migraine or chronic migraine was associated with a significantly lower likelihood of opioid use (OR, 0.38).

REPORTING FROM AHS 2019
Thelarche and menarche are associated with increased prevalence of migraine
PHILADELPHIA – , according to research presented at the annual meeting of the American Headache Society. The results suggest that earlier exposure to estrogen increases the risk for migraine in adolescent girls, said Vincent Martin, MD, director of the Headache and Facial Pain Center at the University of Cincinnati Gardner Neuroscience Institute.
Previous studies observed an association between earlier onset of menarche and greater prevalence of migraine in adolescent girls, but no investigators had examined the relationship between earlier stages of pubertal development, such as thelarche and pubarche, and migraine.
Dr. Martin and colleagues included participants in the Breast Cancer and Environment Research Program puberty cohort in their study. Physicians examined the girls every 6 to 12 months from the time that they were aged 6-8 years to the time of late adolescence. During the last examination, participants responded to a validated questionnaire to determine whether they met International Classification of Headache Disorders–3 criteria for a diagnosis of migraine. Dr. Martin and colleagues performed logistic regression to examine whether age at thelarche, pubarche, or menarche predicted migraine.
Of 761 girls included in this study, 85 (11.2%) received a diagnosis of migraine. The mean age at which the questionnaire was administered was 15.6 years. After adjusting the data for potential confounders, the researchers found that an earlier age of onset of thelarche and menarche was associated with a higher prevalence of migraine. A 1-year decrease in the age of onset of thelarche or menarche was associated with a 32.8% or 33.8% increase in the odds of migraine headache, respectively. Pubarche was not associated with migraine.

PHILADELPHIA – , according to research presented at the annual meeting of the American Headache Society. The results suggest that earlier exposure to estrogen increases the risk for migraine in adolescent girls, said Vincent Martin, MD, director of the Headache and Facial Pain Center at the University of Cincinnati Gardner Neuroscience Institute.

EXPERT ANALYSIS FROM AHS 2019
Nerve transfer improves function after spinal cord injury
according to research published online July 4 ahead of print in the Lancet. Combining nerve transfer with tendon transfer may maximize the functional benefit of surgery.
The loss of upper extremity function after cervical spinal cord injury can reduce independence and social and vocational engagement. People with tetraplegia rank improvement in hand function as their most important goal. Tendon transfers have been the traditional method of restoring function, but interest in nerve transfers has been increasing with the publication of successful results. Nerve transfers can reanimate several muscles at once and require a smaller incision and shorter immobilization, compared with tendon transfers.
Injury had occurred less than 18 months previously
Natasha van Zyl, MBBS, a plastic and reconstructive surgeon at Austin Health in Melbourne, and colleagues conducted a prospective case series to examine the clinical and functional outcomes of nerve transfer surgery for the reanimation of upper limb function in patients with tetraplegia. The investigators also sought to compare these outcomes with published outcomes for tendon transfer surgery.
Between April 14, 2014, and Nov. 22, 2018, Dr. van Zyl and colleagues recruited consecutive patients of any age with early cervical spinal cord injury of motor level C5 and below. Injury was required to have occurred fewer than 18 months before enrollment. Eligible participants had been referred to a single center for upper extremity reanimation and were considered candidates for nerve transfer.
Every participant underwent single or multiple nerve transfers in one or both upper limbs, and some participants also underwent tendon transfers. The goal of surgery was the restoration of elbow extension, grasp, pinch, and hand opening. An independent assessor evaluated participants at baseline and at 12 months and 24 months after surgery. The primary outcome measures were the action research arm test (ARAT), the grasp release test (GRT), and the spinal cord independence measure (SCIM).
Grasp function improved significantly
Dr. van Zyl and colleagues recruited 16 participants with traumatic spinal cord injury who underwent 59 nerve transfers. Ten participants also underwent tendon transfers. The population’s mean age at time of injury was 27.3 years. Three patients were female. Motor vehicle accidents were the most common cause of injury (31%). Follow-up data at 24 months were unavailable for three patients.
Participants’ median ARAT total score significantly improved from 16.5 at baseline to 34.0 at 24 months. Median GRT total score significantly improved from 35.0 at baseline to 125.2 at 24 months. The population’s mean total SCIM score and mobility in the room and toilet SCIM score improved by more than the minimal detectable change and the minimal clinically important difference. The mean self-care SCIM score improved by more than the minimal detectable change between baseline and 24 months.
The researchers observed six adverse events related to the surgery, but none had sustained functional consequences. No patients had an increase in musculoskeletal or neuropathic pain. Four of the 50 nerve transfers with 24-month follow-up failed.
A novel technique
“This project is the first to comprehensively examine outcomes for early, multiple nerve transfer surgery in the upper limbs of people with tetraplegia following traumatic spinal cord injury and is the largest prospective series of nerve transfers reported in this population to date,” said Dr. van Zyl and colleagues. Study limitations included the small sample size, the high variability of spinal cord injury patterns, and the potential for the multiple procedures that each participant underwent to confound data analysis.
Future research could explore whether nerve transfers are beneficial at more than 24 months after spinal cord injury, wrote the authors. In addition, it is unclear whether function and strength continue to improve beyond 24 months after surgery.
The study was funded by the Institute for Safety, Compensation, and Recovery Research in Australia. The authors had no competing interests.

The data from van Zyl et al. suggest that nerve transfers restore more natural movement and finer motor control than tendon transfers do, said Elspeth J.R. Hill, MD, PhD, and Ida K. Fox, MD, plastic and reconstructive surgeons at Washington University in St. Louis, in an accompanying editorial. Patients can engage in light activity immediately after surgery, and cortical plasticity enables function to improve over time. Two disadvantages of nerve transfers, however, are that it takes months before new motion can be observed, and years before full strength can be regained.
The heterogeneity of cervical spinal cord injury requires an individualized approach to surgical assessment and management, they continued. Physicians and patients should make treatment decisions collaboratively. “We envisage a role for nerve transfers in settings where the intensive therapy and immobilization required to optimize complementary tendon transfers are unavailable,” wrote Dr. Hill and Dr. Fox.
Continuing research will be necessary to improve surgical technique and outcomes. “This research should include efforts to compare nerve transfer with tendon transfer, find the optimal timing of such surgeries, and determine which approach produces the greatest functional improvement,” they wrote. “Detailed study of the reasons for nerve transfer failure is also required, as is improving our understanding of the effects of biopsychosocial factors, including access to information and care, psychological readiness, and social support, on patient decision making and outcomes.”
Nerve transfers are a “huge advance” in the restoration of function after spinal cord injury, the authors added. “Surgeons who integrate nerve transfers into their spinal cord injury practice should take a careful and measured approach and rigorously study and disseminate their outcomes to advance this growing field,” they concluded.

Maternal migraine is associated with infant colic
PHILADELPHIA – , according to research presented at the annual meeting of the American Headache Society. Fathers with migraine are not more likely to have children with colic, however. These findings may have implications for the care of mothers with migraine and their children, said Amy Gelfand, MD, associate professor of neurology at the University of California, San Francisco.
Smaller studies have suggested associations between migraine and colic. To examine this relationship in a large, national sample, Dr. Gelfand and her research colleagues conducted a cross-sectional survey of biological parents of 4- to 8-week-olds in the United States. The researchers analyzed data from 1,419 participants – 827 mothers and 592 fathers – who completed online surveys in 2017 and 2018.
Parents provided information about their and their infants’ health. The investigators identified migraineurs using modified International Classification of Headache Disorders 3rd edition criteria and determined infant colic by response to the question, “Has your baby cried for at least 3 hours on at least 3 days in the last week?”
In all, 33.5% of the mothers had migraine or probable migraine, and 20.8% of the fathers had migraine or probable migraine. Maternal migraine was associated with increased odds of infant colic (odds ratio, 1.7). Among mothers with migraine and headache frequency of 15 or more days per month, the likelihood of having an infant with colic was even greater (OR, 2.5).
“The cause of colic is unknown, yet colic is common, and these frequent bouts of intense crying or fussiness can be particularly frustrating for parents, creating family stress and anxiety,” Dr. Gelfand said in a news release. “New moms who are armed with knowledge of the connection between their own history of migraine and infant colic can be better prepared for these often difficult first months of a baby and new mother’s journey.”
