Sex Differences in the Expression of Central Sensitization Symptoms in Migraine: An Observational Study.

Background: Migraine is the fourth most common cause of disability in women and the eighth most common cause in men. Central sensitization phenomena predispose to chronic migraine and are generally more pronounced in women. Objective: The aim of this retrospective observational study was to look for sex differences in a population of migraine subjects attending a tertiary headache center, focusing on symptoms of central sensitization such as allodynia and pericranial tenderness. Methods: This study is based on data collected at a tertiary headache center between January 1, 2018, and December 31, 2022. The clinical interview included the main features of migraine, allodynia, a disability questionnaire, the pericranial tenderness score, and anxiety and depression scales. Results: We selected a total of 1,087 migraine subjects (233 men). Osmophobia predominated in women, as did nausea. Disability scores, headache intensity, allodynia, anxiety, and depression predominated in women, without menopausal age playing a role. The frequency of symptomatic medication use was similar in both sexes. Allodynia score was the largest discriminating factor between women and men. Conclusions: Women with migraine are more likely than men to report acute allodynia, nausea, and osmophobia and are also more likely to be anxious, depressed, and disabled. These features appear to be independent of fertile age and are probably related to sex-specific genetic characteristics. These symptoms represent a tendency toward sensory hypersensitivity and central sensitization that should be carefully assessed in both women and men with migraine with a view to possibly predicting chronic development.

Use of medications for migraine in Aotearoa New Zealand.

To document and assess acute and preventive medication use in people with migraine disease in Aotearoa New Zealand. Online survey of people with migraine in Aotearoa New Zealand (n=530), run from 22 August to 7 October 2022, including questions on current and previous acute and preventive medication use, reasons for medication discontinuation and use of new migraine medications. Most respondents had used simple analgesics for acute treatment; 55% were currently using a triptan; 27% were currently using an opioid. Overall, 27% of survey respondents had over-used at least one acute medication in the last month. Half of respondents were taking at least one preventive medication but only 57% of those eligible for preventive treatment were currently taking it. In those who had previously tried preventives, side effects and lack of efficacy were common reasons for stopping. Cost, lack of knowledge and awareness were the main barriers to use of new migraine medications. Many people with migraine in Aotearoa New Zealand are not receiving optimal treatment, which increases the burden and cost of migraine disease. More effective and tolerable acute and preventive medications are needed that are affordable and available in Aotearoa New Zealand. Greater awareness of best practice prescribing is also needed.

Efficacy and safety of atogepant, a small molecule CGRP receptor antagonist, for the preventive treatment of migraine: a systematic review and meta-analysis

BackgroundMigraine is one of the most common diseases worldwide while current treatment options are not ideal. New therapeutic classes of migraine, the calcitonin gene-related peptide (CGRP) antagonists, have been developed and shown considerable effectiveness and safety. The present study aimed to systematically evaluate the efficacy and safety of atogepant, a CGRP antagonist, for migraine prophylaxis from the results of randomized controlled trials (RCTs).MethodsThe Cochrane Library, Embase, PubMed and https://www.clinicaltrials.gov/ were searched for RCTs that compared atogepant with placebo for migraine prophylaxis from inception of the databases to Feb 1, 2024. Outcome data involving efficacy and safety were combined and analyzed using Review Manager Software version 5.3 (RevMan 5.3). For each outcome, risk ratios (RRs) or standardized mean difference (SMD) were calculated.Results4 RCTs with a total of 2813 subjects met our inclusion criteria. The overall effect estimate showed that atogepant was significantly superior to placebo in terms of the reduction of monthly migraine (SMD − 0.40, 95% CI -0.46 to -0.34) or headache (SMD − 0.39, 95% CI -0.46 to -0.33) days, the reduction of acute medication use days (SMD − 0.45, 95% CI -0.51 to -0.39) and 50% responder rate (RR 1.66, 95% CI 1.46 to 1.89), while no dose-related improvements were found between different dosage groups. For the safety, significant number of patients experienced treatment-emergent adverse events (TEAEs) with atogepant than with placebo (RR 1.10, 95% CI 1.02–1.21) while there was no obvious difference between the five dosage groups. Most TEAEs involved constipation (RR 2.55, 95% CI 1.91–3.41), nausea (RR 2.19, 95% CI 1.67–2.87) and urinary tract infection (RR 1.49, 95% CI 1.05–2.11). In addition, a high dosage of atogepant may also increase the risk of treatment-related TEAEs (RR 1.64, 95% CI 1.02–2.63) and fatigue (RR 3.07, 95% CI 1.13–8.35).ConclusionsThis meta-analysis suggests that atogepant is effective and tolerable for migraine prophylaxis including episodic or chronic migraine compared with placebo. It is critical to weigh the benefits of different doses against the risk of adverse events in clinical application of atogepant. Longer and multi-dose trials with larger sample sizes are required to verify the current findings.

Migraine epidemiology in collegiate student-athletes: Findings from the Concussion Assessment, Research, and Education (CARE) Consortium.

This cross-sectional study evaluated de-identified data from the National Collegiate Athletic Association-Department of Defense Grand Alliance from 2014 to 2020 to determine the prevalence of migraine and migraine medication and to describe differences in migraine prevalence by sex, race, and sport. Epidemiological studies can help identify underdiagnosed and undertreated populations. Understanding migraine prevalence in collegiate student-athletes is essential for positive healthcare outcomes including development of prevention and treatment plans. From a concussion baseline assessment, participant's self-reported demographics (e.g., age, sex, sport), migraine diagnosis (i.e., yes/no), and migraine medication usage (e.g., yes/no, type) determined prevalence of migraine and medication use in collegiate student-athletes. Migraine was reported in 5.6% (2617/47,060; 95% confidence interval [CI] 5.4%-5.8%) of the student-athletes, with higher prevalence in females, 7.5% (1319/17,628; 95% CI 7.1%-7.9%), than males, 4.6% (1298/28,116; 95% CI 4.4%-4.9%). Medication usage was reported by 36.2% (947/2617; 95% CI 34.3%-38.0%) of individuals with migraine. Migraine reporting differed by race, with Caucasian reporting highest (5.9%; 1990/33,913; 95% CI 5.6%-6.1%) and Asian the lowest (2.7%; 55/2027; 95% CI 2.1%-3.5%). Women's sports, including golf, gymnastics, and lacrosse, and men's diving and squash had higher migraine reporting than other sports. Caucasian females reported higher rates than other groups and sport influenced rates of migraine diagnosis.

Causality between multiple autoimmune disorders and migraine and its subtypes: a two-sample Mendelian randomization study.

Several studies have reported associations between various autoimmune diseases and migraine. Using Mendelian randomization (MR), this study aimed to evaluate the interplay between autoimmune diseases and migraine. Here, instrumental variables, exposure factors, and outcome factors for 10 common autoimmune diseases and migraine and its subtypes were screened. This screening utilized comprehensive statistics from Europe's largest genome-wide association study and performed reverse MR analysis on positive results. The causality between autoimmune diseases and migraine was comprehensively assessed using multiple analytical methods. Additionally, sensitivity analyses, such as the horizontal diversity heterogeneity and leave-one-out method, were performed. Random-effects inverse variance weighting analysis revealed a causal correlation between autoimmune hyperthyroidism and migraine (p = 0.0002), and this association was consistent across both migraine with aura (MA; p = 0.006) and migraine without aura (MO; p = 0.017). In addition, there was a positive causal association between systemic lupus erythematosus (SLE) and MA (p = 0.001) and between hypothyroidism and MO (p = 0.038). There is insufficient evidence to substantiate a causal link between outcomes and other autoimmune-related disorders, and reverse MR results did not reveal a causal relationship between migraines and these autoimmune disorders. The validity of the results was demonstrated by a sensitivity analysis; horizontal pleiotropy and heterogeneity were not observed. This study observed a positive genetic association between autoimmune hyperthyroidism and migraines. In addition, SLE positively affects MA, and hypothyroidism contributes to the incidence of MO. These results have great significance for future research and prevention of migraine.

Impact of duration of chronic migraine on long-term effectiveness of monoclonal antibodies targeting the calcitonin gene-related peptide pathway-A real-world study.

We assessed whether the effectiveness of monoclonal antibodies (mAbs) targeting the calcitonin gene-related peptide (CGRP) pathway changes according to the duration of chronic migraine (CM) over 12 months. In most patients, CM is a progressive disease starting with episodic migraine. Longer CM duration might be associated with more difficult treatment, probably because the mechanisms underlying chronicization are strengthened. Therefore, early treatment of CM could lead to better outcomes compared with later treatment. This cohort study included individuals with CM treated with anti-CGRP mAbs in two tertiary headache centers from April 2019 to May 2023. The primary outcome included a change in monthly migraine days (MMDs) from baseline to the third trimester of treatment, 10-12 months. Secondary outcomes established whether response to anti-CGRP mAbs has a more rapid onset in individuals with shorter CM duration compared with longer duration; they included change in MMDs, monthly headache days (MHDs), and days and number of intakes of acute medication during each trimester compared to baseline. Additional outcomes included persisting MMDs, MHDs, and days and number of intakes of acute medication during each trimester of treatment. Patients were compared across tertiles of the overall CM duration. The study included 335 individuals with CM, with a median (interquartile range [IQR]) age of 48 (39-57) years; 270 (80.6%) were women. Patients in the highest tertile of CM duration (aged 18-60 years) were older than patients in the lower duration tertiles (0-7 years and 8-18 years, respectively), with a median (IQR) age of 56 (48-64) years compared with 42 (31-50) years, and 48 (39-56)years, respectively (p = 0.025); however, this difference was likely due to a correlation between age and disease duration. The change in MMDs from baseline to the last trimester of treatment (10-12 months) was comparable across tertiles of CM duration (median [IQR] -12 [-18 to -5] days, -12 [-17 to -6] days, and -12 [-18 to -4] days; p = 0.946). No difference emerged in secondary outcomes, suggesting a similar time to onset of anti-CGRP mAbs effect across all tertiles of CM duration. Our data showed that anti-CGRP mAbs are effective and have a rapid onset of action in CM regardless of disease duration.

Association of dietary and lifestyle inflammation score (DLIS) with chronic migraine in women: a cross-sectional study

Due to more frequent and intense attacks, chronic migraine (CM) sufferers usually report more disability compared to patients with episodic migraine (EM). There is increasing evidence that points to inflammatory diet and lifestyle as a probable underlying cause of migraine. The present study investigated the association of dietary and lifestyle inflammation scores (DLIS) with the odds of CM in Iranian women. In the current study, 285 women with migraine enrolled. Migraine was diagnosed by a single neurologist based on the third edition of the International Classification of Headache Disorders (ICHD-III). The women were categorized into CM and EM groups based on their attack frequency per month. Adherence to the dietary inflammation score (DIS), Lifestyle Inflammatory Score (LIS), and DLIS (DIS + LIS) was assessed based on last year’s dietary intakes collected using a semi-quantitative food frequency questionnaire (FFQ). The Odds Ratio (OR) for CM across the DIS, LIS, and DLIS tertiles were assessed through logistic regression. Most of the participants were overweight or obese (74.4%). The percentage of women with CM was 40.7%. Women with CM had significantly higher DIS (P = 0.002) and DLIS (P = 0.04) than women with EM. There was a significant positive association between CM and DIS. Those in the third tertile of the DIS had almost two times higher chance of experiencing chronic migraine compared with those in the first tertile [OR = 2.02; 95% CI 1.06–3.82; P = 0.03]. the P-value for the trend also was significant (0.03). In terms of LIS and DLIS tertiles, no significant association was observed. Adherence to the more inflammatory diets was associated with higher chances of experiencing CM in women.

Surgical resection of pediatric craniocervical junction Rosai-Dorfman histiocytosis-a case report and literature review.

Rosai-Dorfman disease (RDD) with craniocervical junction involvement is a rare clinical entity. We present herein a case of a pediatric patient with craniocervical junction RDD which was surgically treated. A 10-year-old female with a history of B-cell acute lymphoblastic leukemia (B-ALL) in remission and RDD presented with frontal migraine headaches. She previously had a right posterior chest wall lesion which was biopsy-proven RDD. She was found on imaging to have a dural-based right craniocervical junction lesion. Given her history of B-ALL, after a multidisciplinary discussion, the decision was made to proceed with resection with possible initiation of cobimetinib or clofarabine. The patient underwent a suboccipital craniotomy, C1 laminectomy, and resection of the dural-based lesion. Gross total resection was achieved, and histopathology confirmed the diagnosis of RDD. She was discharged home on postoperative day 4. No recurrence was seen on follow-up imaging at 3months. We conducted a systematic literature review examining all cases of pediatric intracranial RDD and all cases of craniocervical junction RDD. This represents, to the best of our knowledge, only the second case of pediatric craniocervical junction RDD. Although RDD is often self-limiting, medical treatment is often considered for intracranial disease, but tissue confirmation is necessary. Surgical resection provides histopathologic diagnosis and can sometimes serve as definitive treatment for a particular lesion.

Inflammatory response of leptomeninges to a single cortical spreading depolarization

BackgroundNeurogenic 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.MethodsA 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.ResultsThree 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.ConclusionA 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.

Measurement of Serum Ceruloplasmin, Lipid Hydroperoxide Level and Prolidase Activity in Children with Primary Headache

Introduction Primary headache is a significant health problem in children as it remarkably negatively affects the child and his/her family. Migraine and tension-type headaches constitute the majority of primary headaches in childhood. Studies regarding adult migraine patients suggest that oxidative stress has a significant role in the pathogenesis. This study aimed to investigate the relationship between primary headache in chidhood and the levels of oxidative stress markers. Materials and methods Pediatric patients diagnosed with primary headache and healthy controls in the pediatric age range were recruited. Data regarding age, gender, height, weight, and body mass index (BMI) were recorded. The levels of ceruloplasmin, lipid hydroperoxide, and prolidase activity were measured in plasma using the ELISA method. Statistical analyses were conducted using the SPSS 11.5 statistical program. A p-value of less than 0.05 was considered significant. Results The study included 76 patients with primary headache and 61 healthy controls. The mean ages of the patients and healthy controls were 14.4±3.2 and 13.6±2.9 years. The patient and control groups were similar in terms of gender distribution (p=0.948), age (p=0.079), and BMI (p=0.196). Migraine accounted for 35.5% (n=27), while tension-type headache accounted for 64.5% (n=49) of the patients. Serum ceruloplasmin (p=0.033), lipid hydroperoxide (p<0.001), and prolidase (p=0.010) levels were higher in patients compared to the control group. Lipid hydroperoxide (p=0.021) and prolidase (p=0.013) levels were higher in migraine patients than in tension-type headache patients, while ceruloplasmin levels were similar between patients with different headache types (p=0.581). Conclusion In this study, oxidative stress markers were shown to be increased in pediatric patients with primary headache. These findings support the hypothesis that patients with primary headaches are exposed to oxidative stress. Future studies may elucidate the role of oxidative stress in the etiopathogenesis of childhood migraine and other headache types.

Pharmacological investigation of genistein for its therapeutic potential against nitroglycerin-induced migraine headache.

Migraine, typically occurs on one side of the head, lasts for hours to days. Trigemino-vascular system (TVS) plays a vital role in pain generation, with neurogenic inflammation and oxidative stress playing key roles in its pathophysiology. This study aimed to investigate genistein's potential as anti-inflammatory and anti-oxidant agent in mitigating migraine pain. Genistein (20 and 50mg/kg) was administered intraperitoneally (IP) to nitroglycerin (NTG; 10mg/kg)-induced migraine model in rats. Behavioral analysis, antioxidant assay, immunohistochemistry (IHC), histopathological examination, ELISA, and RT-PCR were conducted to evaluate the antimigraine potential of genistein. In-silico analysis showed genestien's ACE values of -4.8 to -9.2 Kcal/mol against selected protein targets. Genistein significantly reversed mechanical and thermal nociception, light phobicity, and head scratching; increased the intensities of GST, GSH, catalase; and down regulated lipid peroxidase (LPO) in cortex and trigeminal nucleus caudalis (TNC). It also reduced Nrf2, NF-kB, and IL6 expression, analyzed through IHC, improved histopathological features, and increased COX-2 and decreased PPAR-γ expressions, while RT-PCR analysis revealed increased PPAR-γ expressions in genistein-treated rats. Genistein exhibited potent antioxidant and anti-inflammatory properties in migraine treatment, acting through multifactorial mechanisms by modulating the expression of numerous proteins in the region cortex and TNC.

Comparison of patients with chronic and episodic migraine with healthy individuals by brain volume and cognitive functions

Objectives: Migraine is a complex neurological disease. In addition to headache, individuals with migraine may develop structural changes inside the brain and cognitive impairment. There is increased evidence associated with impairments in brain volume and cognitive functions in patients with migraine. The present study aimed to investigate the impairment in memory function in individuals with migraine using brain magnetic resonance imaging, volume measurement, and neuropsychological tests. Methods: The study included 20 patients with episodic migraine, 20 patients with chronic migraine, and 20 healthy controls. Subcortical volumes of all participants were measured by FreeSurfer, an automatic segmentation method. The Wechsler Memory Scale-Revised Form (WMS-R), Stroop test, Raven’s Standard Progressive Matrices, Verbal Fluency Test, and Lines Orientation Test were applied in all the study participants. Results: Putamen volume decreased as migraine duration increased, and subcortical gray matter, left cerebellar cortex, and bilateral thalamus volumes were lower in the chronic and episodic group compared to the control group, bilateral putamen and right cerebellar cortex volumes were lower in patients with chronic migraine compared to patients in episodic migraine and control groups. Upon neuropsychological examination, delayed memory was affected as the duration of migraine increased, and there was impairment in patients with chronic migraine upon fluency tests and mental control tests. Conclusions: Changes in subcortical volume and cognitive effects in patients with migraine raise questions about whether migraine qualifies as a benign disease. Structural changes and cognitive impairment may contribute to migraine-associated disability, and therefore, these causalities should be investigated by future studies. Silent infarcts, white matter damage, and cortical spreading depression, which occur in migraine cases, may be associated with subcortical volume changes and thus, cognitive effects. In the context, studies with larger samples to achieve a better understanding are needed.

Response to Botulinum Toxin Type-A in Patients with Refractory Chronic Migraine

Background: Due to its debilitating nature, refractory chronic migraine (RCM) is primarily associated with a poor quality of life. However, controversy remains regarding the efficacy and safety of botulinum toxin for treating RCM. Objectives: The aim of this study was to investigate the efficacy of botulinum toxin type A (BTX-A) in patients with RCM. Methods: In this retrospective cross-sectional study conducted between April 2016 and March 2021, RCM patients who were resistant to conventional therapies and received BTX-A injections were followed for 7 and 14 days after the injection. The outcome variables included the frequency, duration, and severity of migraine episodes, the need for painkillers, adverse events, and the patient's perceived improvement. Data were analyzed using SPSS. Results: In total, 52 RCM patients with a mean age of 31.84 years participated, of whom 69.2% were female. The frequency of migraine episodes decreased from a baseline of 9.84 to 3.94 and 1.25 at 7 and 14 days after injection, respectively (P < 0.001). The duration of migraine episodes dropped from 3 hours at baseline to 1.74 and 1.17 hours at 7 and 14 days post-BTX-A injection, respectively (P < 0.001). The severity of migraines alleviated from 8.07 at baseline to 6.48 and 3.38 at the respective follow-up times (P < 0.001). The need for painkillers also decreased at follow-ups (P < 0.001). Males achieved better treatment outcomes regarding the frequency of migraine episodes and the need for medications compared to females following BTX-A treatment (P < 0.05). Frontotemporal and frontotemporal-occipital headache distributions showed fewer migraine episodes, shorter duration, less severity, and lower need for painkiller consumption compared to other migraine types (P < 0.05). The most common adverse event was localized pain (42.3%), followed by itching (25.0%). A considerable number of patients felt improvement. Conclusions: According to our findings, BTX-A is a safe and well-tolerated treatment for patients with RCM. Validation of these results requires adequately precise studies investigating the effect of BTX-A in detail.

Effects of aerobic and resistance exercises on psychological and cognitive functions in patients with post-stroke migraine

ABSTRACT Objective To investigate the impact of a combination of aerobic and resistance exercises on the psychological and cognitive functions of post-stroke migraine patients. Methods This study recruited 100 patients suffering from post-stroke migraine pain who were admitted to the hospital, categorizing them into a control group (n = 50) and an intervention group (n = 50). The control group received conventional drug treatment, while the intervention group received the exercise-based intervention that combined aerobic exercise with resistance exercise. Results Before treatment, both groups displayed similar Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Disorder-7 (GAD-7), Mini-mental State Examination (MMSE) and MoCA scores. However, after the intervention, the intervention group exhibited lower scores on these measures compared to the control group (all p < 0.05). Additionally, there were no discernible disparity in Migraine Disability Assessment (MIDAS) and Headache Impact Test (HIT-6) scores between the two cohorts of patients before treatment (p > 0.05), whereas the intervention group demonstrated significantly lower MIDAS and HIT-6 scores following the intervention (p < 0.05). Although there were no discernible distinctions in National Institute of Health stroke scale (NIHSS) and Stroke Specialized Quality of Life Scale (SS-QOL) measurements between the two patient groups before treatment (p > 0.05), the intervention group exhibited a significant decrease in NIHSS scores and a notable increase in SS-QOL scores after the intervention (p > 0.05). Moreover, the satisfaction rate and overall satisfaction rate were significantly higher in the intervention group (p < 0.05). Conclusion The combination of aerobic and resistance exercises demonstrated positive effects on the psychological well-being and overall quality of life for post-stroke migraine patients.

Efficacy and Safety of Atogepant for Preventing Chronic and Episodic Migraines: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Efficacy and Safety of Atogepant for Preventing Chronic and Episodic Migraines: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

The Modern Clinician as an "Argonaut" Guiding Through the "Symplegades" of Evidence for PFO Closure in Patients With Migraine.

Patent foramen ovale (PFO) has been associated with migraine, especially migraine with aura, and 30-50% of individuals with migraine with aura have a PFO, suggesting it could be more than just an "innocent bystander''. Observational data showed a reduction of the frequency and severity of migraine attacks, particularly those with aura, following transcatheter PFO closure for established indications. Three small randomized controlled trials have demonstrated significant benefits of PFO closure in most of their secondary endpoints, such as reductions in the mean number of monthly migraine attacks and migraine days. Since a significant proportion of patients experience important side effects from traditional migraine medications and newer highly effective migraine prevention strategies may need to be instituted. PFO closure could in this regard to be a valuable add-on in the armamentarium of migraine treatment, improving the quality of life by alleviating the need for medications. The effect of percutaneous PFO closure on migraine treatment is needed to be clarified. As the underlying pathophysiology remains poorly understood and largely hypothetical, future investigations, focusing on the causal relationship between PFO and migraine, will help to define the subgroup of patients most likely to benefit from PFO closure. More accurate patient recruitment may lead to greater postprocedural benefits and more significant symptom improvement. Additionally, randomized controlled trials need to be reported adequately with more realistic endpoints, sufficient duration of follow-up, and statistical power to detect differences between closure and placebo groups to ensure precise and reliable findings.

Poor Adherence to the Mediterranean Diet and Sleep Disturbances Are Associated with Migraine Chronification and Disability among an Adult Population in the Lazio Region, Italy.

Lifestyle factors, such as diet and sleep quality, are receiving increasing interest as accessible therapeutic approaches to migraine. The Mediterranean diet (MD) has shown clear benefits in cardiovascular and metabolic diseases, as well as in sleep patterns. Here, our objective was to identify the impact of adherence to the MD and other lifestyle factors on the clinical burden of migraine. For this purpose, we enrolled 170 migraine patients and 100 controls, assessing the clinical disability of headache using standardized clinical scales (HIT-6 and MIDAS) in the migraineur cohort and lifestyle patterns in both groups through the PREDIMED score for MD adherence, the IPAQ scale for physical activity, and BMI. Subjects were also screened for sleep-wake disturbances based on the Pittsburgh Sleep Quality Index (PSQI). We found that migraine patients had lower adherence to the MD compared to the controls and that the HIT-6 scale had a significant negative relationship with MD adherence in patients with high-frequency episodic and chronic migraine. Additionally, in the same migraine patients, the presence of sleep-wake disturbances was correlated with greater migraine disability as assessed by the MIDAS score. In conclusion, this study found that among different lifestyle factors, poor adherence to the MD and the presence of sleep-wake disturbances were closely associated with migraine disability and chronification.

Neuromodulation treatments for migraine: a contemporary update.

Neuromodulation approaches have been a part of a revolution in migraine therapies with multiple devices approved or in development. These devices vary in the nerve(s) being targeted, implantable versus noninvasive form factors as well as their effectiveness for acute pain reduction or migraine prevention. This review will summarize these recent advancements and approaches that are being developed which build upon prior work and improved technology that may help enhance the effectiveness as well as the patient experience. Both noninvasive and implantable devices primarily targeting cranial nerves have shown the ability to help alleviate migraine symptoms. Multiple prospective and retrospective studies have demonstrated clinically meaningful reductions in headache intensity with noninvasive approaches, while prevention of migraine demonstrates more modest effects. Implantable neuromodulation technologies focusing on occipital and supraorbital stimulation have shown promise in migraine/headache prevention in chronic migraine patients, but there is a need for improvements in technology to address key needs for surgical approaches. Electrical neuromodulation approaches in the treatment of migraine is undergoing a transformation towards improved outcomes with better technologies that may suit various patient needs on a more individualized basis.

CARPAL TUNNEL SYNDROME AND MIGRAINE LATERALIZATION

Abstract Background/Aims: Within the scope of this research, we aimed to elucidate the relationship between carpal tunnel syndrome and migraine to explore both the pain intensity and the localization of carpal tunnel syndrome (CTS) in concomitant migraine. The primary outcome variable was elaborated as the pain lateralization, and the secondary outcome variable was the pain intensity. Methods: This was a cross-sectional, observational prospective study of 500 patients with a preliminary carpal tunnel syndrome diagnosis in our institution. After patients with missing data were excluded from the study, 413 remained, 365 (88.4%) women and 48 (11.6%) men. After recording the demographic characteristics, the patient's migraine pain year of onset of pain, pain characteristics, localization, frequency, duration, severity, triggering factors, symptoms, and findings accompanying the pain were recorded. Results: The lateralization of migraine was on the right side (only on the right or mostly on the right) in 25.9% and on the left side (only on the left or mostly on the left) in 26.4% of the patients. Almost half of the patients (47.7%) experienced bilateral migraine headaches. Carpal tunnel syndrome was in the right hand in 13.3%, in the left hand in 11.6%, and bilateral in 75.1%. Of 197 patients with bilateral pain, 68 (34.5%) had mild, 116 (58.9%) had moderate, and 13 (6.6%) had severe CTS. The VAS level of migraine pain was higher only in patients with CTS in the left hand and in those with moderate CTS. Conclusion: It has been determined that those with carpal tunnel syndrome on the right side have migraines mostly on the right, those with carpal tunnel syndrome on the left have migraines on the left, and those with carpal tunnel syndrome in both directions have migraines predominantly in both directions.
