RESUMEN
OBJECTIVE: To observe the clinical effect of prophylaxis on migraine without aura differentiated as liver yang hyperactivity undergoing acupuncture at the points selected using the "seven lines of the neck" method. METHODS: Fifty-eight patients with migraine without aura of liver yang hyperactivity at remission stage were randomly divided into an observation group (29 cases, 3 cases dropped out) and a control group (29 cases, 4 cases dropped out). In the observation group, acupuncture was delivered at Dazhui (GV 14), Fengfu (GV 16), bilateral Fengchi (GB 20), Gongxue (Extra), etc., selected using the "seven lines of the neck" method. In the control group, conventional acupuncture was applied to ashi point, Sizhukong (TE 23), Shuaigu (GB 8), Taiyang (EX-HN 5) and others on the affected side. The treatment was given once every other day or every two days, 3 interventions weekly, for consecutive 8 weeks. Before treatment, after 4 and 8 weeks of treatment, and after 4 weeks of treatment completion (follow-up visit), the days of migraine episodes, the frequency of migraine episodes, the score of visual analogue scale (VAS) for pain intensity, and the score of migraine specific quality of life questionnaire (MSQ) were observed in the patients of the two groups. Before treatment and after 8 weeks of treatment, the score of TCM syndrome was observed. After 4 and 8 weeks of treatment and after 4 weeks of treatment completion (follow-up visit), the response rates of 50% reduction in the days and the frequency of migraine episodes were calculated in the two groups. RESULTS: After 4 and 8 weeks of treatment and during follow-up visit, the days and the frequency of migraine episodes were decreased (P<0.01) and VAS scores were declined (P<0.01) when compared with those before treatment in the two groups. The days and the frequency of migraine episodes in the observation group were lower during the follow-up visit (P<0.05) and VAS scores were lower after 8 weeks of treatment and during the follow-up visit (P<0.05) when compared with those in the control group. After 4 and 8 weeks of treatment, and during follow-up visit, the scores of "role function-preventive" and "emotional function" of MSQ were increased in comparison with those before treatment in the observation group (P<0.05). After 8 weeks of treatment and during the follow-up visit, the scores of "role function-restrictive" of MSQ were increased in comparison with those before treatment in the observation group (P<0.05), and the scores of "role function-restrictive" "role function-preventive" and "emotional function" were higher when compared with those before treatment in the control group (P<0.05). After 8 weeks of treatment, the scores of TCM syndrome were decreased in comparison with those before treatment in the two groups (P<0.01). In the observation group, the response rate of 50% reduction in the days of migraine episodes after 8 weeks of treatment and that of the frequency of migraine episodes during the follow-up visit were higher than those of the control group (P<0.05). CONCLUSION: Acupuncture at the points selected using the "seven lines of the neck" method can reduce the days and frequency of migraine episodes and pain intensity, ameliorate the syndrome of TCM and improve the quality of life of the patients with migraine without aura of liver yang hyperactivity.

OBJECTIVE: To compare the clinical effect between heat-sensitive moxibustion and mild moxibustion for migraine without aura. METHODS: A total of 54 patients with migraine without aura were randomized into an observation group (27 cases, 2 cases dropped off) and a control group (27 cases, 2 cases dropped off). The basic western medication treatment was adopted in the two groups. In the control group, mild moxibustion was applied at Shuaigu (GB 8), Fengchi (GB 20) and Yanglingquan (GB 34) on the affected side. In the observation group, the frequent acupoint areas of the affected side i.e. Shuaigu (GB 8), Fengchi (GB 20), Taiyang (EX-HN 5), Taichong (LR 3), Yanglingquan (GB 34) were determined, 3 acupoints with strong heat-sensitive sensation were selected each time and mild moxibustion was adopted. The treatment was given once a day, 5 times of treatment was as one course and 2 courses were required in the two groups. Before and after treatment, the scores of migraine symptom, visual analogue scale (VAS), migraine specific quality of life questionnaire (MSQ) were observed, and the clinical efficacy was evaluated after treatment in the two groups. RESULTS: After treatment, the scores of migraine symptom and VAS were decreased compared with those before treatment (P<0.01), while the MSQ scores were increased compared with those before treatment (P<0.01) in the two groups. After treatment, the scores of migraine symptom and VAS in the observation group were lower than those in the control group (P<0.05), while the MSQ score in the observation group was higher than that in the control group (P<0.01). The total effective rate was 92.0% (23/25) in the observation group, which was superior to 72.0% (18/25) in the control group (P<0.05). CONCLUSION: Both heat-sensitive moxibustion and mild moxibustion can effectively alleviate the clinical symptoms, improve the headache degree and life quality in patients with migraine without aura, the clinical efficacy of heat-sensitive moxibustion is superior to that of mild moxibustion.

Transcutaneous auricular vagus nerve stimulation (taVNS) shows excellent effects on relieving clinical symptoms in migraine patients. Nevertheless, the neurological mechanisms of taVNS for migraineurs remain unclear. In recent years, voxel-wise degree centrality (DC) and functional connectivity (FC) methods were extensively utilized for exploring alterations in patterns of FC in the resting-state brain. In the present study, thirty-five migraine patients without aura and thirty-eight healthy controls (HCs) were recruited for magnetic resonance imaging scans. Firstly, this study used voxel-wise DC analysis to explore brain regions where abnormalities were present in migraine patients. Secondly, for elucidating neurological mechanisms underlying taVNS in migraine, seed-based resting-state functional connectivity analysis was employed to the taVNS treatment group. Finally, correlation analysis was performed to explore the relationship between alterations in neurological mechanisms and clinical symptoms. Our findings indicated that migraineurs have lower DC values in the inferior temporal gyrus (ITG) and paracentral lobule than in healthy controls (HCs). In addition, migraineurs have higher DC values in the cerebellar lobule VIII and the fusiform gyrus than HCs. Moreover, after taVNS treatment (post-taVNS), patients displayed increased FC between the ITG with the inferior parietal lobule (IPL), orbitofrontal gyrus, angular gyrus, and posterior cingulate gyrus than before taVNS treatment (pre-taVNS). Besides, the post-taVNS patients showed decreased FC between the cerebellar lobule VIII with the supplementary motor area and postcentral gyrus compared with the pre-taVNS patients. The changed FC of ITG-IPL was significantly related to changes in headache intensity. Our study suggested that migraine patients without aura have altered brain connectivity patterns in several hub regions involving multisensory integration, pain perception, and cognitive function. More importantly, taVNS modulated the default mode network and the vestibular cortical network related to the dysfunctions in migraineurs. This paper provides a new perspective on the potential neurological mechanisms and therapeutic targets of taVNS for treating migraine.

Migraine without aura (MWoA) is a major neurological disorder with unsatisfactory adherence to current medications. Acupuncture has emerged as a promising method for treating MWoA. However, the brain mechanism underlying acupuncture is yet unclear. The present study aimed to examine the effects of acupuncture in regulating brain connectivity of the key regions in pain modulation. In this study, MWoA patients were recruited and randomly assigned to 4 weeks of real or sham acupuncture. Resting-state functional magnetic resonance imaging (fMRI) data were collected before and after the treatment. A modern neuroimaging literature meta-analysis of 515 fMRI studies was conducted to identify pain modulation-related key regions as regions of interest (ROIs). Seed-to-voxel resting state-functional connectivity (rsFC) method and repeated-measures two-way analysis of variance were conducted to determine the interaction effects between the two groups and time (baseline and post-treatment). The changes in rsFC were evaluated between baseline and post-treatment in real and sham acupuncture groups, respectively. Clinical data at baseline and post-treatment were also recorded in order to determine between-group differences in clinical outcomes as well as correlations between rsFC changes and clinical effects. 40 subjects were involved in the final analysis. The current study demonstrated significant improvement in real acupuncture vs sham acupuncture on headache severity (monthly migraine days), headache impact (6-item Headache Impact Test), and health-related quality of life (Migraine-Specific Quality of Life Questionnaire). Five pain modulation-related key regions, including the right amygdala (AMYG), left insula (INS), left medial orbital superior frontal gyrus (PFCventmed), left middle occipital gyrus (MOG), and right middle cingulate cortex (MCC), were selected based on the meta-analysis on brain imaging studies. This study found that 1) after acupuncture treatment, migraine patients of the real acupuncture group showed significantly enhanced connectivity in the right AMYG/MCC-left MTG and the right MCC-right superior temporal gyrus (STG) compared to that of the sham acupuncture group; 2) negative correlations were established between clinical effects and increased rsFC in the right AMYG/MCC-left MTG; 3) baseline right AMYG-left MTG rsFC predicts monthly migraine days reduction after treatment. The current results suggested that acupuncture may concurrently regulate the rsFC of two pain modulation regions in the AMYG and MCC. MTG and STG may be the key nodes linked to multisensory processing of pain modulation in migraine with acupuncture treatment. These findings highlighted the potential of acupuncture for migraine management and the mechanisms underlying the modulation effects.

INTRODUCTION: Migraine is a common neurological disorder with a higher prevalence occurring in women. Migraine without aura (MwoA) is the most common type of migraine. In recent years, the safety and effectiveness of acupuncture for migraines have been internationally recognised. Contralateral acupuncture (CAT) (Jùcì) is an ancient classic acupuncture technique from Huang Di Nei Jing that refers to the acupoints on the right side (healthy side) selected for diseases on the left (affected side) and vice versa. Some studies have shown that efficacy of CAT on the painful disorder is even better than ipsilateral acupuncture (IAT), but there remains a lack of high-quality evidence to support it. METHODS AND ANALYSIS: This is a single-centre, randomised and sham-controlled clinical trial in China with three parallel groups that aim to evaluate the efficacy of CAT in women with unilateral MwoA. 243 participants will be randomly divided into the experimental group (CAT group), control group 1 (IAT group) and control group 2 (sham acupuncture group) (1:1:1 allocation ratio). Each group will be given 30-minute treatment sessions, once every other day, approximately three times per week, for a total of 24 treatments and follow-up visits two times. The primary outcome is the changes in days of migraine attacks. The secondary outcomes are frequency of migraine attacks, intensity of migraine, migraine duration, the dose of intake of acute medication, the Migraine-Specific Quality of Life Questionnaire, the Migraine Disability Assessment Score, the Headache Impact Test-6 and the Pittsburgh Sleep Quality Index. The data will be collected at the baseline time (week 0), end of treatment (week 4-8) and the follow-up time (week 12-16). Adverse events will be collected and recorded during each treatment. ETHICS AND DISSEMINATION: Ethics approval was obtained from the Ethics Committee of the Sports Trauma Specialist Hospital of Yunnan Province (2021-01). All participants will provide written informed consent before randomisation. The results of this study will be published in a peer-reviewed journal and presented at conferences. TRIAL REGISTRATION NUMBER: Chinese Clinical Trial Registration Center (ChiCTR2100051479).

OBJECTIVE: To observe therapeutic effect of acupuncture on migraine without aura and the changes of brain functional connectivity (FC) using resting-state functional magnetic resonance imaging (rs-fMRI). METHODS: Thirty-four patients with migraine without aura were included into an observation group and treated with acupuncture at Baihui (GV 20), Xuanlu (GB 5), Shuaigu (GB 8), Taiyang (EX-HN 5), etc. Using G6805-â ¡ electric acupuncture apparatus, the ipsilateral Fengchi (GB 20) and Shuaigu (GB 8) were connected and stimulated with continuous wave, 2 Hz in frequency and 0.1 mA to 1.0 mA in current intensity, depending on patient's tolerance. Acupuncture stimulation lasted 20 min each time, twice weekly (at the interval>2 days). A total of 6 weeks of treatment (12 times) was required. Matching the gender and age as those of the observation group, 16 healthy subjects were recruited into a control group and no any intervention was provided. The headache days, the score of visual analogue scale (VAS) for headache severity, the total score of headache symptoms, the score of migraine-specific quality of life questionnaire (MSQ), the score of self-rating anxiety scale (SAS), and the score of self-rating depression scale (SDS) were compared before and after acupuncture, and the clinical efficacy was assessed in the observation group. The data of the resting-state functional magnetic resonance were collected in the observation group before and after treatment as well as the control group at baseline. The periaqueductal gray (PAG) was taken as the seed to analyze the effect of acupuncture on the brain FC and the correlation between FC and VAS scores, headache days in the patients of migraine without aura. RESULTS: After treatment, the headache days, VAS score, the total score of headache symptoms, SAS score and SDS score were all reduced (P<0.01); and the scores of the restrictive, preventive, and emotional functional domains of the MSQ were increased (P<0.01) in the observation group compared with those before treatment. The total effective rate was 94.1% (32/34). Compared with the control group, FC between PAG and the right cerebellum â § was decreased in the observation group before treatment (P<0.05). FC of PAG with the bilateral cerebellum â § and the left precuneus was increased in the observation group after treatment compared with those before treatment (P<0.05). In the observation group, the FC intensity of PAG and the right cerebellum â § was negatively correlated with VAS score (r =-0.41, P<0.05) before treatment, while the FC intensity of PAG and the left precuneus was positively correlated with the improvement in headache days (r =0.40, P<0.05) after treatment. CONCLUSION: Acupuncture is effective on migraine without aura. The brain functional connectivity is abnormal in the patients. The effect onset of acupuncture is obtained probably by regulating the abnormal brain regions and activating brain regions relevant with pain and emotions.

OBJECTIVE: We compared the incremental effects of adding acceptance and commitment therapy (ACT) to pharmacological treatment as usual (TAU) in a sample of patients with high frequency episodic migraine without aura (HFEM), assessing impact on a spectrum of measures across multiple domains. BACKGROUND: Patients with HFEM are at risk of developing chronic migraine and medication overuse headache. ACT has been shown to be effective for the treatment of various chronic pain conditions, but little attention has been given to its therapeutic value in the management of recurring headaches. METHODS: In this single-blind (masking for outcome assessor), open-label, randomized clinical trial, 35 patients with HFEM, with a monthly headache frequency ranging from 9 to 14 days, were recruited at the headache center of C. Besta Neurological Institute and randomized to either TAU (patient education and pharmacological prophylaxis; n = 17) or TAU + ACT (n = 18). Patients assigned to the combined treatment arm additionally received six 90-min weekly group sessions of ACT therapy and two supplementary "booster" sessions. All patients were on a stable course of prophylactic medication in the 3 months prior to initiating either treatment. Monthly headache frequency served as the primary outcome measure, with all other data collected being considered as secondary measures (medication intake, disability, headache impact, anxiety and depression, catastrophizing, allodynia, cognitive inflexibility, pain acceptance, mindful attention and awareness). RESULTS: A total of 35 patients were enrolled: 17 randomized to TAU, of whom three dropped out, and 18 to TAU + ACT (no dropouts in this group). Headache frequency and medication intake decreased in both groups over 12 months, with patients in the TAU + ACT group showing statistically significant reduction earlier, that is, by month 3. Headache frequency was reduced by 3.3 days (95% CI: 1.4 to 5.2) among those randomized to ACT + TAU, whereas it increased by 0.7 days (95% CI: -2.7 to 1.3) among those randomized to TAU only (p = 0.007, partial η2 = 0.21), the difference being 4 days (95% CI: 1.2 to 6.8). Medication intake was reduced by 4.1 intakes (95% CI: 2.0 to 6.3) among those randomized to ACT + TAU and by 0.4 intakes (95% CI: -1.8 to 2.5) among those randomized to TAU only (p = 0.016; partial η2 = 0.17), the difference being 3.8 intakes (95% CI: 0.7 to 6.8). At 6 and 12 months, the variations were not different between the two groups for headache frequency and medication intake. The opposite was found for measures of headache impact and pain acceptance, where the differences over time favored patients allocated to TAU. Both groups improved with regard to measures of disability, anxiety and depression, catastrophizing, and cognitive inflexibility, whereas measures of allodynia and pain acceptance were stable over time. CONCLUSIONS: Our preliminary findings indicate that supplementing TAU with ACT can enhance the main clinical outcomes, namely headache frequency and medication intake of patients with HFEM.

OBJECTIVE: To observe the clinical effect of penetrating moxibustion on migraine without aura (MO) patients. METHODS: Totally 60 MO patients from the Acupuncture Clinic of the Third Affiliated Hospital of Henan University of Chinese Medicine were collected from November 2015 to February 2017. All patients were assigned to a treatment group and a control group using a random number table, 30 cases in each group. The treatment group was treated with penetrating moxibustion, and the control group was treated with mild moxibustion, thrice a week for 4 consecutive weeks. The total effective rate, Visual Analogue Scale (VAS) scores, headache intensity, and Migraine Specific Quality of Life Questionnaire (MSQ) scores of patients after treatment were compared between the two groups. The moxibustion sensation and reaction after moxibustion were observed, and the adverse reactions were evaluated. All patients were followed up at 4 and 16 weeks after treatment. RESULTS: The total effective rate of the treatment group was significantly higher than that of the control group (93.33% vs. 80.00%, P<0.05). The improvement of VAS scores, headache intensity, and the role restrictive and role preventive scores in MSQ in the treatment group was better than those in the control group (P<0.05). The person-time of moxibustion sensations of itching, numbness and cold as well as flushing and sweating after moxibustion in the treatment group was all significantly higher than that in the control group (P<0.01). There was no significant difference in safety evaluation between the two groups (P>0.05). CONCLUSIONS: Penetrating moxibustion can significantly relieve pain and improve quality of life of MO patients. After penetrating moxibustion, flushing and sweating of patients were obvious, and the curative effect was superior to the mild moxibustion.

OBJECTIVES/BACKGROUND: Auriculotemporal neuralgia is a rare headache disorder. Anesthetic nerve blockade seems to be effective in most cases; however, literature is scarce about the management of refractory cases. METHODS: Case report. RESULTS: We report a 44-year-old woman with migraine without aura presented with moderate-to-severe right temporoparietal headache. The pain was refractory to multiple pharmacological strategies, including intravenous analgesia. A more throughout examination lead to the diagnosis of auriculotemporal neuralgia and anesthetic nerve blocks were performed. Due to early pain recrudescence, botulinum toxin (BoNT) was tried with better and longstanding pain control. CONCLUSION: BoNT may be a useful treatment option in refractory auriculotemporal neuralgia. The best approach is yet to be established; however, the "follow-the-pain" protocol may be a reasonable option.

OBJECTIVE: The relation between migraine and vascular risk factors is an unclear issue. Furthermore, the reasons for chronification are still unknown. Probably, the age-related risk and other factors leading to migraine progression will also change in the future. Under these questions, we aimed to investigate whether or not there is a specific association with vascular risk factors between several age groups and subtypes of migraine and also in their families. METHODS: A dataset (the Turkish Headache Database) from four tertiary headache centres in Turkey was used. This database included headache-defining features according to ICHD criteria based on face-to-face interviews and examinations by a Neurologist. Vascular risk factors of migraine without aura (MwoA), migraine with aura (MwA) and chronic migraine (CM) were compared between three age groups (under 30 years, 30-50 years and over 50 years) and in first-degree relatives of the patients. Our study included 2712 patients comprising 1868 (68.9 %), 246 (9.1 %) and 598 (22.1 %) subjects with MwoA, MwA and CH, respectively. RESULTS: This study showed that both the patients and the first-degree relatives were more frequently associated with vascular risk factors in CM than episodic MwA and MwoA. MwoA showed a weaker association with vascular risk factors than MwA and CM. CONCLUSION: Chronic migraine was associated with vascular risk factors at all ages and first-degree relatives as well. Vascular risk factors should be investigated with greater focus on chronic migraine.

Background: A growing body of evidence suggests that both auricular acupuncture and transcutaneous auricular vagus nerve stimulation (taVNS) can induce antinociception and relieve symptoms of migraine. However, their instant effects and central treatment mechanism remain unclear. Many studies proved that the amygdalae play a vital role not only in emotion modulation but also in pain processing. In this study, we investigated the modulation effects of continuous taVNS at acupoints on the FC of the bilateral amygdalae in MwoA. Methods: Thirty episodic migraineurs were recruited for the single-blind, crossover functional magnetic resonance imaging (fMRI) study. Each participant attended two kinds of eight-minute stimulations, taVNS and sham-taVNS (staVNS), separated by seven days in random order. Finally, 27 of them were included in the analysis of seed-to-voxel FC with the left/right amygdala as seeds. Results: Compared with staVNS, the FC decreased during taVNS between the left amygdala and left middle frontal gyrus (MFG), left dorsolateral superior frontal gyrus, right supplementary motor area (SMA), bilateral paracentral lobules, bilateral postcingulum gyrus, and right frontal superior medial gyrus, so did the FC of the right amygdala and left MFG. A significant positive correlation was observed between the FC of the left amygdala and right SMA and the frequency/total time of migraine attacks during the preceding four weeks. Conclusion: Continuous taVNS at acupoints can modulate the FC between the bilateral amygdalae and pain-related brain regions in MwoA, involving the limbic system, default mode network, and pain matrix, with obvious differences between the left amygdala and the right amygdala. The taVNS may produce treatment effects by modulating the abnormal FC of the amygdala and pain networks, possibly having the same central mechanism as auricular acupuncture.

Migraine headache (MH) is a common disorder affecting millions of people in the United States. MH is substantially more prevalent in women compared to men. An association between migraine with or without aura and risk of cardiovascular disease (CVD) has been extensively reported. There are several proposed theories that may explain the pathophysiologic relationship between MH and CVD. This review will summarize the recent literature on this topic and provide an evidence-based perspective regarding the current knowledge and controversies regarding association of MH and CVD.

BACKGROUND: The American Registry for Migraine Research (ARMR) is a multicenter, prospective, longitudinal patient registry, biorepository, and neuroimaging repository that collects clinical data, electronic health record (EHR) data, blood samples, and brain imaging data from individuals with migraine or other headache types. In this manuscript, we outline ARMR research methods and report baseline data describing an initial cohort of ARMR participants. METHODS: Adults with any International Classification of Headache Disorders (ICHD) diagnosis were prospectively enrolled from one of the 8 participating headache specialty centers. At baseline, ARMR participants complete web-based questionnaires, clinicians enter the participant's ICHD diagnoses, an optional blood specimen is collected, and neuroimaging data are uploaded to the ARMR neuroimaging repository. Participants maintain the ARMR daily headache diary longitudinally and follow-up questionnaires are completed by participants every 3 months. EHR data are integrated into the ARMR database from a subset of ARMR sites. Herein, we describe the ARMR methodology and report the summary data from ARMR participants who had, from February 2016 to May 2019, completed at least 1 baseline questionnaire from which data are reported in this manuscript. Descriptive statistics are used to provide an overview of patient's sociodemographics, headache diagnoses, headache characteristics, most bothersome symptoms other than headache, headache-related disability, comorbidities, and treatments. RESULTS: Data were available from 996 ARMR participants, enrolled from Mayo Clinic Arizona, Dartmouth-Hitchcock Medical Center, University of Utah, University of Colorado, Thomas Jefferson University, University of Texas Health Science Center at Houston, Georgetown University Medical Center, and DENT Neurological Institute. Among ARMR participants, 86.7% (n = 864) were female and the mean age at the time of enrollment was 48.6 years (±13.9; range 18-84). The most common provider-reported diagnosis was chronic migraine (n = 622), followed by migraine without aura (n = 327), migraine with aura (n = 196), and medication overuse headache (n = 65). Average headache frequency was 19.1 ± 9.2 days per month (n = 751), with 68% reporting at least 15 headache days per month. Sensitivity to light was the most frequent (n = 222) most bothersome symptom overall, other than headache, but when present, cognitive dysfunction was most frequently (n = 157) the most bothersome symptom other than headache. Average migraine disability assessment (MIDAS) score was 52 ± 49 (n = 760), (very severe headache-related disability); however, 17% of the ARMR population had MIDAS scores suggesting "no" or "mild" disability. The most common non-headache health issues were allergies (n = 364), back pain (n = 296), neck pain (n = 296), depression (n = 292), and anxiety (n = 278). Nearly 85% (n = 695) of patients were using preventive medications and 24.7% were using non-medication preventive therapy (eg, vitamins and neuromodulation). The most common preventive medication classes were neurotoxins, anticonvulsants, antidepressants, vitamins/supplements, and anticalcitonin gene-related peptide ligand or receptor-targeted monoclonal antibodies. Nearly 90% (n = 734) of ARMR participants was taking medications to treat migraine attacks, with the most common classes being triptans, non-steroidal anti-inflammatory drugs, antiemetics, acetaminophen, and combination analgesics. CONCLUSIONS: ARMR is a source of real-world patient data, biospecimens, and brain neuroimaging data that provides comprehensive insight into patients with migraine and other headache types being seen in headache specialty clinics in the United States. ARMR data will allow for longitudinal and advanced analytics that are expected to lead to a better characterization of patient heterogeneity, healthcare resource utilization, identification of endophenotypes, factors that predict treatment outcomes and clinical course, and ultimately advance the field toward precision headache medicine.

Migraine is a major public health problem afflicting approximately 10% of the general population and is a leading cause of disability worldwide, yet our understanding of the basis mechanisms of migraine remains incomplete. About a third of migraine patients have attacks with aura, consisting of transient neurological symptoms that precede or accompany headache, or occur without headache. For patients, aura symptoms are alarming and may be transiently disabling. For clinicians and scientists, aura represents an intriguing neurophysiological event that may provide important insight into basic mechanisms of migraine. Several observations point toward important differences between migraine with and without aura. Compared with migraine without aura, migraine with aura has different heritability, greater association with different conditions including stroke, different alterations of brain structure and function as revealed by imaging studies. A number of studies also indicate that migraine with aura may respond differently to acute and preventive therapies as compared to migraine without aura. The purpose of this review is to provide an overview of these differences in treatment responses, and to discuss the possibility of different therapeutic strategies for migraine with vs. without aura.

BACKGROUND: In the context of a causal relationship between stress and migraine, coping strategies are aimed at managing stressful life events and reducing the distressing emotions connected to them. METHODS: Sixty-one consecutive patients with migraine without aura (MwoA) and sixty-one healthy controls (HCs) completed three self-report questionnaires assessing a broad range of coping (cognitive and behavioural) strategies: the Coping Orientation to Problems Experienced (COPE), the Coping Inventory for Stressful Situation (CISS), and the Proactive Coping Inventory (PCI). Moreover, the Perceived Stress Scale (PSS), a scale measuring self-perception of stress, global cognitive functioning, depressive symptoms, apathy, state, and trait anxiety, was administered to all participants. RESULTS: No significant difference was found on the scales and subscales of PCI and CISS as well as in the PSS between MwoA patients and HCs. However, the two groups showed different scores in the subscale "turning to religion" of COPE (22.08 ± 5.19 in migraineurs vs. 24.70 ± 4.44 in HCs, p = 0.003). A significant negative correlation of the turning to religion score with the HIT-6 score was found. CONCLUSIONS: The present study revealed that MwoA patients show a significantly reduced use of the "turning to religion" approach, an emotion-focused coping strategy. Although migraine patients appeared to be less oriented to transcendent (that means a reduced utilization of an adaptive coping strategy), they did not perceive daily living as more stressful than HCs. Finally, the reduced utilization of the "turning to religion" coping strategy is associated with a great impact of migraine on ability to function on the job or at school, at home, and in social situations in migraine patients.

To investigate whether interindividual variability of white matter (WM) tract microstructure of the medial prefrontal cortex (mPFC)-amygdala circuit could predict 8-week placebo treatment outcomes in patients with migraine without aura (MO) using diffusion tensor imaging (DTI) with a tractography atlas-based analysis algorithm and a linear support vector machine algorithm. This study received institutional review board approval, and all subjects gave informed consent. One hundred and twenty-four MO had an 8-week sham acupuncture treatment. Patients were subdivided into recovering (MOr, >50% improvement in migraine attack frequency after treatment) and persisting (MOp, <50% reduction in number of migraine days). Neuroimaging was collected via magnetic resonance imaging (MRI) in all subjects. Patients were imaged during the interictal phase of migraine (at least 72 hr after, and not within 24 hr of a migraine) before the treatment. WM microstructures were quantified along the selected fiber pathway and were used to evaluate the discrimination performance for classifying MOr and MOp. The combined features of diffusion measures from vertices along the pathways of the mPFC-amygdala accurately discriminated MOr from MOp migraineurs with an accuracy of 84.0% (p < .005, permutation test). The most discriminative WM features that contributed to the classification were located in the external capsule and ACC/mPFC. Our findings suggested that the variability of placebo treatment outcomes in migraineurs could be predicted from priori diffusion measures along the fiber pathways of the mPFC-amygdala, which may demonstrate a potential of WM neuroimaging features as imaging markers for identifying placebo responders in migraine patients.

PURPOSE OF REVIEW: To review the pathophysiologic, epidemiologic, and clinical evidence for similarities and differences between migraine with and without aura. RECENT FINDINGS: The ICHD-3 has recently refined the diagnostic criteria for aura to include positive symptomatology, which better differentiates aura from TIA. Although substantial evidence supports cortical spreading depression as the cause of visual aura, the role (if any) of CSD in headache pain is not well understood. Recent imaging evidence suggests a possible hypothalamic origin for a headache attack, but further research is needed. Migraine with aura is associated with a modest increase in the risk of ischemic stroke. The etiology for this association remains unclear. There is a paucity of evidence regarding treatments specifically aimed at the migraine with aura subtype, or whether migraine with vs without aura responds to treatment differently. Migraine with typical aura is therefore often treated similarly to migraine without aura. Lamotrigine, daily aspirin, and flunarizine have evidence for efficacy in prevention of migraine with aura, and magnesium, ketamine, furosemide, and single-pulse transcranial magnetic stimulation have evidence for use as acute treatments. Although triptans have traditionally been contraindicated in hemiplegic migraine and migraine with brainstem aura, this prohibition is being reconsidered in the face of evidence suggesting that use may be safe. The debate as to whether migraine with and without aura are different entities is ongoing. In an era of sophisticated imaging, genetic advancement, and ongoing clinical trials, efforts to answer this question are likely to yield important and clinically meaningful results.

INTRODUCTION: Connectivity within the primary motor cortex can be measured using the paired-pulse transcranial magnetic stimulation (TMS) paradigm. This evaluates the effect of a first conditioning stimulus on the motor evoked potential (MEP) elicited by a second test stimulus when different interstimulus intervals are used. Aim of the present study was to provide, in patients suffering from migraine without aura (MwoA), additional information on intracortical facilitation (ICF), short intracortical inhibition (SICI), and long intracortical inhibition (LICI), using different intensities of the test stimulus (TS). METHODS: We enrolled 24 patients with episodic MwoA and 24 age- and sex-matched healthy volunteers. Both patients and controls were randomly assigned to two different experimental groups: the first group underwent evaluation of ICF, while in the second group we assessed SICI and LICI. All these measures were assessed by using three different suprathreshold intensities of the TS (110%, 130% and 150% of the resting motor threshold, RMT). Interstimulus intervals (ISIs) of 10 ms were used for testing ICF, while SICI and LICI were carried out by using 2 ms and 100 ms ISIs respectively. All migraine patients underwent the experimental protocol while in the interictal pain-free state. RESULTS: A main finding of the study was that an increased ICF could be seen in migraineurs as compared to the healthy subjects only by using a 110% intensity of the TS. Instead, no significant differences were observed between patients and controls as regards both measures of intracortical inhibition. CONCLUSION: We show that hyperresponsivity of the glutamatergic intracortical circuits can be detected in the migraine motor cortex only by applying a low suprathreshold intensity of stimulation. Our results strengthen the notion that, to be reliable, the assessment of cortical excitability in migraine should always include evaluation of the cortical response to different stimulation intensities.
