Aberrant functional connectivity in anterior cingulate gyrus subregions in migraine without aura patients.

Background: The anterior cingulate gyrus (ACG) is an important regulatory region for pain-related information. However, the ACG is composed of subregions with different functions. The mechanisms underlying the brain networks of different subregions of the ACG in patients with migraine without aura (MwoA) are currently unclear. Methods: In the current study, resting-state functional magnetic resonance imaging (rsfMRI) and functional connectivity (FC) were used to investigate the functional characteristics of ACG subregions in MwoA patients. The study included 17 healthy volunteers and 28 MwoA patients. The FC calculation was based on rsfMRI data from a 3 T MRI scanner. The brain networks of the ACG subregions were compared using a general linear model to see if there were any differences between the two groups. Spearman correlation analysis was used to examine the correlation between FC values in abnormal brain regions and clinical variables. Results: Compared with healthy subjects, MwoA patients showed decreased FC between left subgenual ACG and left middle cingulate gyrus and right middle temporal gyrus. Meanwhile, MwoA patients also showed increased FC between pregenual ACG and right angular gyrus and increased FC between right pregenual ACG and right superior occipital gyrus. The FC values between pregenual ACG and right superior occipital gyrus were significantly positively correlated with the visual analogue scale. Conclusion: Disturbances of FC between ACG subregions and default model network and visual cortex may play a key role in neuropathological features, perception and affection of MwoA. The current study provides further insights into the complex scenario of MwoA mechanisms.

Headache-related disability as a function of migraine aura: A daily diary study.

OBJECTIVE: To examine the unique role of migraine aura in predicting day-to-day levels of headache-related disability. BACKGROUND: Migraine symptoms and psychological variables contribute to headache-related disability. Migraine aura may be associated with more severe symptom profiles and increased risk of psychiatric comorbidities, but the impact of aura on daily functioning is unknown. The present study sought to evaluate the role of migraine aura in predicting same-day and subsequent-day migraine-related disability while accounting for demographic, headache, and psychological variables. METHODS: This was an observational prospective cohort study among 554 adults with migraine. For each participant, data on migraine symptoms and psychological variables were collected daily for 90 days using the N-1 Headache™ digital app (N = 11,156 total migraine days). Analyses assessed whether the presence of aura predicted daily ratings of migraine-related disability independently of other headache and psychological variables. Given the number of predictors examined, statistical significance was set at p < 0.01. RESULTS: The mean (standard deviation, range) patient-level Migraine Disability Assessment questionnaire score across days of the migraine episode was 1.18 (1.03, 0-3). Aura was significantly associated with higher disability ratings on all days of the migraine episode (odds ratio [OR] 1.40, 99% confidence interval [CI] 1.13-1.74; p < 0.001). This relationship remained unchanged after adjusting for patient-level variables (OR 1.40, 99% CI 1.13-1.73; p < 0.001) and day-level psychological variables (OR 1.39, 99% CI 1.12-1.73; p < 0.001) but was fully negated after controlling for day-level headache variables (OR 1.19, 99% CI 0.95-1.49; p = 0.039). Aura on the first day of the episode was associated with increased odds of allodynia (OR 1.87, 99% CI 1.22-2.86; p < 0.001), phonophobia (OR 1.62, 99% CI 1.17-2.25; p < 0.001), photophobia (OR 1.89, 99% CI 1.37-2.59; p < 0.001), and nausea/vomiting (OR 1.54, 99% CI 1.17-2.02; p < 0.001) on all days of the episode, but not episode duration (p = 0.171), peak severity (p = 0.098), or any examined psychological variables (sleep duration [p = 0.733], sleep quality [p = 0.186], stress [p = 0.110], anxiety [p = 0.102], or sadness [p = 0.743]). CONCLUSION: The presence of aura is predictive of increased headache-related disability during migraine episodes, but this effect is attributable to associated non-pain symptoms of migraine.

Average steps per day as marker of treatment response with anti-CGRP mAbs in adults with chronic migraine: a pilot study.

Physical activity can worsen migraine, leading to reduced activity levels in adults with chronic migraine. This study investigated the change in average steps per day, as a surrogate marker of physical activity, in adults with chronic migraine successfully treated with monoclonal antibodies against calcitonin gene-related peptide or its receptor. Data were obtained from adults with chronic migraine, who were classified as responders to preventive treatment with monoclonal antibodies. The primary endpoint was the difference in a mean number of steps per day between the 3 months prior to treatment initiation and the first 3 months after treatment initiation. The secondary endpoint was the correlation between the change in steps per day and the change in monthly migraine days. Twenty-two (20 females) participants with a median age of 48.5 years were enrolled. The median number of steps per day increased from 4421 at baseline to 5241 after treatment (P = 0.039). We found a positive correlation between the increase in steps per day and the treatment response (P = 0.013). In conclusion, an increase in physical activity, based on steps per day, positively correlated with treatment response to monoclonal antibodies. Automatically registered daily step count data might be used to monitor physical activity as a response to preventive treatment in adults with chronic migraine.

Resolution of Sporadic Hemiplegic Migraine by Correcting a Cervical Spine Kyphosis Utilizing the Chiropractic BioPhysics® (CBP®) Technique: A Case Report With Long-Term Follow-Up.

A 19-year-old male suffered from sporadic hemiplegic migraine (SHM) for several years and experienced significant pain and disability with sensory and motor disturbances during the migraine headaches. Weakness, abnormal vision, abnormal sensation, one-sided disabling motor weakness, and other signs of SHM were diagnosed. The patient had received previous physical therapy, chiropractic and over-the-counter medications, as well as migraine-specific prescriptions without lasting improvements. Chiropractic BioPhysics® (CBP®) spinal structural rehabilitation protocols were used to increase cervical lordosis and improve cervical muscular strength, mobility, and posture. These protocols include spine-specific prescriptions for Mirror Image® postural exercises, traction, and spinal manipulative therapy. After 24 treatments over eight weeks, all subjective and objective outcomes improved dramatically with a near resolution of all initial symptoms of SHM. There were a significant increase in cervical lordosis and a reduction in forward head posture. The neck disability index improved from 26% to 6%, and all pain scores for all regions improved following treatment. A 10-month follow-up exam showed the outcomes were maintained. SHM is rare and debilitating, is part of the global burden of disease, and is a major cause of disability in the world. Reports of successful conservative and non-conservative long-term treatments for SHM are rare, and there are no clinical trials showing successful treatments for SHM. This successful case demonstrates preliminary evidence that CBP spinal structural rehabilitation may serve as a treatment option for SHM. Future studies are needed to replicate the findings from this case.

Ocular Manifestations and Complications of Patent Foramen Ovale: A Narrative Review.

Patent foramen ovale (PFO) is a prevalent congenital cardiac anomaly associated with a persistent opening between the atrial septum, allowing communication between the left and right atria. Despite often being asymptomatic, PFO can lead to various clinical presentations, including cryptogenic stroke and other embolic events. Transient visual disturbances, alterations in the visual field, migraine with aura, impaired eye movement and endogenous eye infections may prompt patients to seek ophthalmological consultation. Understanding these diverse clinical scenarios is crucial for early detection, appropriate management and mitigating the morbidity burden associated with PFO. This narrative review aims at examining the spectrum of clinical presentations of ocular pictures associated with PFO. The pathophysiology, diagnosis and treatment methods for PFO will be described, emphasizing the importance of a multidisciplinary approach involving ophthalmologists, cardiologists, neurologists and imaging specialists. In the future, prospective studies and clinical trials are warranted to provide further insights into the preventive role and optimal therapeutic strategies for managing PFO-related ocular complications, ultimately guiding clinical decision making and optimizing patient care.

The involvement of the piriform cortex in non-lesional temporal lobe epilepsy: an uncommon component of the epileptogenic network.

The piriform cortex is recognized as highly epileptogenic in rodents, yet its electrophysiological role in human epilepsy remains understudied. Recent surgical outcomes have suggested potential benefits in resecting the piriform cortex for cases of medial temporal lobe epilepsy. However, little is known about its electrophysiological activity in human epilepsy. This case-series study aimed to explore the electrophysiological role of the piriform cortex within the epileptogenic network among patients with suspected temporal lobe epilepsy. Participants were recruited from Emory University Hospital or Children's Healthcare of Atlanta, with non-lesional frontotemporal or temporal lobe hypotheses, undergoing stereoelectroencephalographic studies. Specifically, focus was placed on patients with one or more electrode contacts in the piriform cortex. Primary objectives included determining piriform cortex involvement within the electrophysiologically defined epileptogenic network and assessing the effects of electrical stimulation. Twenty-two patients were included in the study. Notably, only one patient exhibited piriform cortex involvement at seizure onset, associated with an olfactory aura. Two patients showed early piriform cortex involvement, while others displayed late or no involvement. Electrical stimulation of the piriform cortex induced after-discharges in three patients and replicated a habitual seizure in one. These findings present a contrast to surgical outcome studies, suggesting that the piriform cortex may not typically play a significant role in the epileptogenic network among patients with non-lesional temporal lobe epilepsy.

Evaluation of retinal perfusion density and foveal avascular zone in migraine subjects with and without aura.

Migraine, classified as a neurovascular disease, has been identified as a potential risk factor for ocular vascular complications. Our study aimed to compare retinal vessel density and perfusion density between subjects with migraine and healthy subjects using optical coherence tomography angiography (OCTA). In this cross-sectional case-control study, we enrolled 30 migraine subjects with aura (MWA), 30 migraine subjects without aura (MWOA) and 30 age and gender-matched healthy controls (HC). The foveal avascular zone (FAZ) in superficial capillary plexus (SCP), Vessel density (VD) and perfusion density (PD) in SCP and deep capillary plexus (DCP) were assessed in a 3 × 3 mm scan of the macula with the swept source OCT. Results indicated that the FAZ of MWA and MWOA subjects was significantly larger from HC. Also, FAZ of MWA was larger from MWOA. VD and PD in both SCP and DCP were significantly reduced in both MWA and MWOA groups compared to HC. However, VD and PD did not show significant differences among MWA and MWOA. Additionally, the duration of disease was the main determinant of the FAZ. In conclusion, the FAZ in the SCP, VD and PD in the SCP and DCP of the macula were affected in both MWA and MWOA. FAZ, specifically, was increased with the evolution of the disease. These findings might contribute to an increased risk of ocular vascular complications among subjects with migraine and could potentially use OCTA as a biomarker for this population.

CGRP Modulating Therapies: An Update.

INTRODUCTION: Calcitonin-gene related peptide (CGRP) is a vasoactive neuropeptide involved in the pathophysiology ofmigraine. CGRP has been targeted for both preventive and acute treatment of migraine. OBJECTIVE: Provide a summary of the most clinically relevant literature surrounding CGRP modulating therapies. METHODS: This update on CGRP modulating therapies includes articles selected as most clinically relevant by theauthors. CONCLUSION: CGRP modulating therapies are an exciting new addition to migraine treatment given their safety andtolerability. Additionally, compared to traditional migraine preventive medication these treatments are migrainespecific.Further real-world and clinical data is ongoing to better understand these treatments that continue to gainfavor in the management of migraine.

Profile of Sensory Integration Disorders in Migraine Patients-New Perspectives of Therapy.

Background: The involvement of sensory integration disorders in the pathophysiology of migraine has been suggested. This study aims to analyze the relationship between symptoms of sensory integration disorders and migraine in a broad scope, including all sensory domains, and examine its impact on migraine attacks. Methods: The study included 372 people diagnosed with migraine. The Daniel Travis Questionnaire was used to assess symptoms of sensory integration disorders and their severity across six domains. The relationships between the severity of these symptoms and headache features, as well as accompanying headache symptoms, were the subject of statistical analysis. Results: Current impairment in all sensory domains was significantly associated with headaches exacerbated by everyday life activities. A significant inverse relationship was found between the occurrence of throbbing headaches and symptoms of sensory integration disorders in terms of current sensory discrimination, current motor skills, and current emotional/social skills. Past under-responsiveness and past disturbances in emotional/social abilities were significantly associated with migraine aura. Conclusions: The severity of symptoms of sensory integration disorders affects the clinical picture of migraine. The significant association between migraine and emotional/social disorders, as well as under-responsiveness in the past, needs further research to assess whether this is a cause-and-effect relationship. There is a need for in-depth diagnostics of sensory integration disorders in migraine patients, which could be an additional target of their therapy.

Inflammatory response of leptomeninges to a single cortical spreading depolarization.

BACKGROUND: Neurogenic meningeal inflammation is regarded as a key driver of migraine headache. Multiple evidence show importance of inflammatory processes in the dura mater for pain generation but contribution of the leptomeninges is less clear. We assessed effects of cortical spreading depolarization (CSD), the pathophysiological mechanism of migraine aura, on expression of inflammatory mediators in the leptomeninges. METHODS: A single CSD event was produced by a focal unilateral microdamage of the cortex in freely behaving rats. Three hours later intact cortical leptomeninges and parenchyma of ipsi-lesional (invaded by CSD) and sham-treated contra-lesional (unaffected by CSD) hemispheres were collected and mRNA levels of genes associated with inflammation (Il1b, Tnf, Ccl2; Cx3cl1, Zc3h12a) and endocannabinoid CB2 receptors (Cnr2) were measured using qPCR. RESULTS: Three hours after a single unilateral CSD, most inflammatory factors changed their expression levels in the leptomeninges, mainly on the side of CSD. The meninges overlying affected cortex increased mRNA expression of all proinflammatory cytokines (Il1b, Tnf, Ccl2) and anti-inflammatory factors Zc3h12a and Cx3cl1. Upregulation of proinflammatory cytokines was found in both meninges and parenchyma while anti-inflammatory markers increased only meningeal expression. CONCLUSION: A single CSD is sufficient to produce pronounced leptomeningeal inflammation that lasts for at least three hours and involves mostly meninges overlying the cortex affected by CSD. The prolonged post-CSD inflammation of the leptomeninges can contribute to mechanisms of headache generation following aura phase of migraine attack.

A thorough investigation into the correlation between migraines and the gut microbiome: an in-depth analysis using Mendelian randomization studies.

Objective: A growing body of evidence underscores a significant association between neurological disorders, particularly migraines, and the gut microbiota. However, a research gap persists in understanding the cause-and-effect dynamics between these elements. Therefore, we employed robust methodologies aimed at thoroughly exploring the causal relationship between the gut microbiome and migraines. Methods: Employing bidirectional Two Sample Mendelian Randomization (TSMR) analysis, we investigated the causal association between the composition of the gut microbiota and migraines. Data summarizing the relationship between gut microbiota and migraines were extracted from one or more genome-wide association studies. The TSMR analysis employed five methods to assess the correlation between the gut microbiota and migraines, with the inverse variance-weighted method serving as the primary approach for analyzing causal links. Sensitivity analyses were applied to address horizontal pleiotropy and heterogeneity. Simultaneously, a meta-analysis was performed to strengthen the robustness of the findings. Additionally, a reverse TSMR was carried out to explore potential occurrences of reverse causal relationships. Results: The ongoing TSMR analysis identified a collection of 14 bacterial taxa connected to migraines. Among these, 8 taxa exhibited a protective effect, while 5 taxa had a detrimental impact, and 1 taxon maintained a neutral relationship. The reverse Mendelian randomization analysis highlighted stable outcomes for only one bacterial taxonomic group. Conclusion: The study confirms a causal relationship between the gut microbiota and migraines, offering a new perspective for migraine research. Strategically targeting specific bacterial taxa with dysregulation may be effective in both preventing and treating migraines, thus opening new avenues for therapeutic strategies.

Red ear syndrome: a case series and review of the literature.

BACKGROUND: Red Ear Syndrome is a burning sensation and erythema of the ear, associated with a various number of disorders including migraine, trigeminal neuralgia, autoimmune disorders etc. Theories for RES pathophysiology have developed from current understandings of comorbid conditions. Characterizing the underlying mechanism of RES is crucial for defining effective treatments. CASE PRESENTATION: Three caucasian patients, ages 15, 47, and 67 years, with migraine, one with erythromelalgia are reported in this manuscript. RES pathophysiology is not fully understood due to its variable clinical presentation and numerous comorbid conditions, making it difficult to identify effective treatments. CONCLUSION: RES seems to be largely treatment-resistant, and most options involve treating the associated disorders and minimizing pain. Further investigation of future cases should lead to a more comprehensive understanding of the fundamental cause of RES and, hopefully, successful treatments.

The Burden of Stroke Mimics Among Hyperacute Stroke Unit Attendees with Special Emphasis on Migraine: A 10-Year Evaluation.

BACKGROUND AND OBJECTIVES: Stroke and migraine are common neurological illnesses that cause tremendous suffering for patients. Certain diseases can mimic the clinical manifestations of an actual stroke. Migraine is one of the most commonly reported stroke mimics. The main goals of this study are to look at the prevalence of stroke mimics on the stroke pathway of Sheffield Teaching Hospitals and how many of them are migraines. MATERIALS AND METHODS: A retrospective service evaluation was conducted at the hyperacute stroke unit (HASU) of the Royal Hallamshire Hospital (RHH) in the United Kingdom. The total admissions from 2013 to 2022 were collected from the Sentinel Stroke National Audit Programme database, and the number of stroke mimics was evaluated each year. The burden of migraine stroke mimics was also evaluated. Then, a one-year sample of stroke mimics was extracted to look for the types of each mimic. RESULTS: From 2013 to 2022, 45.75% (n = 12156) of the stroke pathway patients (n = 26573) were stroke mimics, with an increment of up to 55% in the years 2021 and 2022. During these 10 years, migraine stroke mimics accounted for 10.21% of admissions (n = 1240). The three most common mimics in a one-year sample of stroke pathway patients were migraine (14.70%) (n = 373), functional neurological disorders (FNDs) (7.17%) (n = 182), and Guillain-Barré syndrome (6.66%) (n = 169). Seizures, syncope, and metabolic derangements were reported as mimics in 4.17% (n = 106), 3.14% (n = 80), and 1.77% (n = 45), respectively. CONCLUSIONS: About half of the HASU attendees were stroke mimics rather than actual strokes, and the most common mimics were migraines.

Shunt-mediated decompression sickness in a compressed air worker with an atrial septal defect.

We report a compressed air worker who had diffuse cutaneous decompression sickness with pain in his left shoulder and visual disturbance characteristic of migraine aura after only his third hyperbaric exposure. The maximum pressure was 253 kPa gauge with oxygen decompression using the Swanscombe Oxygen Decompression Table. He was found to have a very large right-to-left shunt across a 9 mm atrial septal defect. He had transcatheter closure of the defect but had some residual shunting with release of a Valsalva manoeuvre. Thirty-two other tunnel workers undertook the same pressure profile and activities in the same working conditions during the maintenance of a tunnel boring machine for a total of 233 similar exposures and were unaffected. As far as we are aware this is the first report of shunt-mediated decompression sickness in a hyperbaric tunnel worker in the United Kingdom and the second case reported worldwide. These cases suggest that shunt-mediated decompression sickness should be considered to be an occupational risk in modern compressed air working. A right-to-left shunt in a compressed air worker should be managed in accordance with established clinical guidance for divers.

[The hereditary vessel disease CADASIL].

Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is a hereditary small vessel disease of the brain characterized by progressive white matter lesions, subcortical infarcts, and cognitive decline. This autosomal dominant disorder is caused by mutations in the NOTCH3 gene located on chromosome 19, resulting in the accumulation of granular osmiophilic material within the walls of small arteries and arterioles. Clinically, CADASIL typically manifests in mid-adulthood with recurrent ischemic events, migraine with aura, mood disturbances, and cognitive impairment. Neuroimaging plays a crucial role in the diagnosis of CADASIL, with characteristic findings including white matter hyperintensities particularly in the anterior temporal lobe and external capsule.

Investigating migraine phenotype and dynamics in women with endometriosis: an observational pilot study.

INTRODUCTION: Migraine and endometriosis are chronic disabling pain conditions. There is evidence for a shared genetic background. Migraine phenotype and course in patients with the comorbidity are insufficient investigated. Both conditions can be treated with progestins. METHODS: For this observational study we included women with migraine and endometriosis, visiting our clinic from 2015 to 2021. We collected available information from charts and complemented these data by a structured phone interview to collect more specific information on migraine and the course of both diseases. RESULTS: From 344 patients fulfilling the inclusion criteria, 94 suffered from both, endometriosis and migraine. Migraine with aura was reported by 41% of the patients and was associated with earlier onset of migraine (age < 17 years (OR 6.54) and with a history of medication overuse headache (OR 9.9, CI 1.6-59.4). Present monthly migraine frequency (1.5 ± 2.6) was significantly lower than five years before the interview (2.9 ± 4.64). There was a correlation between medication overuse headache and use of analgesics more than 3 days/months for dysmenorrhoea (p < 0.03). ASRM endometriosis score was not associated with migraine characteristics. CONCLUSIONS: We conclude that the comorbidity of endometriosis is highly linked to migraine with aura. Migraine onset in these patients was earlier. Further studies are needed to explore, if the observed decrease in migraine frequency can be attributed to recent endometriosis surgery and to understand if early diagnosis and treatment of both conditions may contribute to improve the course of both conditions. Trial registration BASEC Nr. 2021-00285.

Migraine-like headache with aura induced by a small infarct in the parieto-occipital cortex: A case report.

A 56-year-old right-handed man was referred to our hospital for evaluation of sudden-onset transient quadrantanopia, which was followed by throbbing headache consistent with migraine with aura (MA). Magnetic resonance imaging (MRI) of the right parieto-occipital cortex on admission showed a hyperintense region on diffusion-weighted imaging, which disappeared 7 days later. A small cortical infarct in the parieto-occipital cortex can cause MA-like headache, and the present infarct lesion was only detectable on MRI during the acute phase. Performing MRI for patients with suspected acute MA might help identify the cause of MA-like headache and ensure appropriate management of patients.

Clinical Characteristics of Migraine and Their Association With the Retinal Nerve Fiber Layer Thickness.

BACKGROUND: Migraine is characterized by recurrent episodes of unilateral, pulsating headaches. At the cerebral and ocular levels, it is recognized that the vascular narrowing and loss of blood flow are transient; however, the chronic nature of migraine may result in long-term functional and structural changes in these structures. It could result in axonal loss and an alteration in the thickness of the retinal nerve fiber layers (RNFL). This study aimed to measure the RNFL thickness, which provides a useful indication of the state of the axons and the loss of ganglion cells in migraine patients, and to find out if RNFL thickness and the clinical features of migraine are correlated. MATERIALS AND METHODS: Sixty patients with migraine and 60 age-gender-matched controls were recruited. A complete neurological and ophthalmological examination was performed, and spectral-domain optical coherence tomography (SD-OCT) was done to measure RNFL. RESULTS: All quadrants of the retina on both sides showed non-statistically significant differences in RNFL thickness between migraine patients and controls (p-value >0.05). Furthermore, in all retinal quadrants on both sides, there was no statistically significant difference in RNFL thickness between migraine patients with aura and those without aura (p-value >0.05). Significant correlations were found between the duration of migraine disease and the superior RNFL thickness of both eyes, as well as the inferior RNFL in the right eye. There was also a significant correlation between the headache attack duration and RNFL thickness of the superior retina (p<0.05), Conclusion: Our key finding was that when comparing migraine patients to controls, RNFL thickness did not significantly change; however, the duration of migraine disease did significantly affect RNFL thickness.

[Prophylaxis of migraine without aura of liver yang hyperactivity treated with acupuncture at the points selected using the "seven lines of the neck" method: a randomized controlled trial].

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.
