Migraine, hormones and the menopausal transition

Relationship between pain activity patterns, and physical and psychological aspects and sleep quality in women with migraine

Migraine can cause different pain activity patterns. This cross-sectional study examines the relationship between pain activity patterns and physical and psychological aspects and sleep quality in women with migraine. Women diagnosed with migraine (n = 129) were reached through social media and announcements. Outcome measures were Pattern of Activity Measure-Pain (POAM-P) (avoidance, overdoing, pacing), Migraine Disability Assessment Scale (MIDAS), International Physical Activity Questionnaire-Short Form (IPAQ-SF), Depression Anxiety Stress Scale-21 (DASS-21), the Pittsburgh Sleep Quality Index (PSQI). While there was a negative correlation between the POAMP-avoidance and the IPAQ-SF rho = -0.178), there were positive correlations between the POAMP-avoidance and the MIDAS (rho = 0.454), the DASS-21-depression (rho = 0.413), the DASS-21-anxiety (rho = 0.321), and the DASS-21-stress (rho = 0.446). There were positive correlations between the POAMP-overdoing, and the DASS-21-depression (rho = 0.229), the DASS-21-stress (rho = 0.207), and the PSQI (rho = 0.217). There were also positive correlations between the POAMP-pacing and the MIDAS (rho = 0.283), the DASS-21-depression (rho = 0.250), and the DASS-21-anxiety (rho = 0.213) (p < .05). Pain activity patterns in women with migraines were associated with their disability, physical activity, psychological state, and sleep quality. Determining treatment based on pain activity patterns can improve migraine treatment outcomes.

Influence of Age and Sex on Post-Craniotomy Headache

Post-craniotomy headache (PCH) is a common postoperative complication, and some of these patients progress to chronic PCH (CPCH). We aimed to identify clinical variables associated with PCH and its progression to CPCH, especially possible associations between age and sex differences. Therefore, we examined clinical information on PCH using the Clinical Data Warehouse over 10 years. Of the 1326 patients included, 927 patients (69.9%) experienced PCH. In multivariate analysis for PCH, age was inversely related to risk (p = 0.003), and being female showed a significant association with an increased risk of PCH (p = 0.002). There was also a significant inverse relationship between age and severity of the worst headache, with younger female patients reporting greater severity of the worst headache (p < 0.001). Of the 927 patients who experienced PCH, 319 (34.4%) progressed to CPCH. Sex was a significant factor, with females having a higher risk of developing CPCH compared to males (p < 0.001). In addition, the presence of preoperative headaches significantly increased the risk of CPCH (p = 0.001). The occurrence of PCH is associated with younger age and female sex. In particular, female sex and preoperative headaches increased the risk of developing CPCH. These clinical factors should be considered in patients undergoing neurosurgery.

Reviewing migraine-associated pathophysiology and its impact on elevated stroke risk

Migraine affects up to 20 percent of the global population and ranks as the second leading cause of disability worldwide. In parallel, ischemic stroke stands as the second leading cause of mortality and the third leading cause of disability worldwide. This review aims to elucidate the intricate relationship between migraine and stroke, highlighting the role of genetic, vascular, and hormonal factors. Epidemiological evidence shows a positive association between migraine, particularly with aura, and ischemic stroke (IS), though the link to hemorrhagic stroke (HS) remains inconclusive. The shared pathophysiology between migraine and stroke includes cortical spreading depression, endothelial dysfunction, and genetic predispositions, such as mutations linked to conditions like CADASIL and MELAS. Genetic studies indicate that common loci may predispose individuals to both migraine and stroke, while biomarkers such as endothelial microparticles and inflammatory cytokines offer insights into the underlying mechanisms. Additionally, hormonal influences, particularly fluctuations in estrogen levels, significantly impact migraine pathogenesis and stroke risk, highlighting the need for tailored interventions for women. The presence of a patent foramen ovale (PFO) in migraineurs further complicates their risk profile, with device closure showing promise in reducing stroke occurrence. Furthermore, white matter lesions (WMLs) are frequently observed in migraine patients, suggesting potential cognitive and stroke risks. This review hopes to summarize the links between migraine and its associated conditions and ischemic stroke, recognizing the profound implications for clinical management strategies for both disorders. Understanding the complex relationship between migraine and ischemic stroke holds the key to navigating treatment options and preventive interventions to enhance overall patient outcomes.

Clinical characterization of pediatric acute confusional migraine: a single-center case series

INTRODUCTION

Acute confusional migraine (ACM) is a rare disorder characteristic of pediatric patients. Our objective was to describe the clinical characteristics of patients diagnosed with ACM who visited our pediatric emergency department (PED).

METHODS

This study was a retrospective review of children who presented to our PED between January 2012 and December 2022 with a discharge diagnosis of ACM.

RESULTS

During the study period, 23 patients were enrolled: 11 males (47.8%) and 12 females (52.2%); median age was 10.8 years (IQR: 8.3-13.6). Eight patients reported a history of headache. The median length of stay of PED was 4.7 h. Onset was abrupt (less than 12 h) in 100% of cases. Changes in the level and content of consciousness occurred in 47.8% and 91.3% of patients, respectively; confusion (73.9%) was the most common neurological manifestation. Eighteen patients had urgent brain CT scans, none showing pathological findings. Four patients required benzodiazepines to control their psychomotor agitation. Nine patients were hospitalized, including one in the intensive care unit. Two patients underwent MRI and one patient underwent EEG during hospitalization, with normal results.

DISCUSSION

ACM is a rare condition in pediatric neurology characterized by acute onset of confusion or altered mental status before, during, or after migraine headache. Clinical features overlap with other neurological disorders, making diagnosis challenging. To improve the diagnosis, treatment, and research of AMC, it is essential to include it in the International Classification of Headache Disorders and establish standardized diagnostic criteria.

Cervical Artery Dissections-A Demographical Analysis of Risk Factors, Clinical Characteristics Treatment Procedures, and Outcomes-A Single Centre Study of 54 Consecutive Cases

Cervical artery dissections (CAD) are a common cause of ischemic cerebrovascular events among the younger and middle-aged population. Altogether, CAD counts for up to 15% of all causes of stroke in patients aged 50 or younger. Among the known etiological causes, especially addressing the younger population with mechanical traumas and whiplash injuries are regarded as the main culprits. However, cases of spontaneous dissection are also widespread, with risk factors such as hypertension, migraine, and lifestyle factors increasing the risk of occurrence. Clinically, the symptoms associated with a cerebrovascular event caused by CADs are highly variable and can be classified as either compressive symptoms (such as Horner's syndrome and cervical pain) or stroke syndromes attributable to cerebral ischemia. Therefore, establishing an early diagnosis might be particularly challenging as it requires particular attention and quick clinical reasoning when interviewing the patient. With these certain particularities, our main focus was to conduct a prospective study involving up to 54 patients who were diagnosed with CAD in our clinical facility between January 2015 and December 2022, with the focus of assessing certain individual parameters attributable to each patient and their influence and prognosis value for their short and long term evolution. An important emphasis was placed on parameters such as topographical localization, clinical presentation, severity of the questioned cerebrovascular event, outcomes, and causative factors. Statistical validity tools were applied when possible.

Considerations for hormonal therapy in migraine patients: a critical review of current practice

INTRODUCTION

Migraine, a neurovascular headache disorder, is a leading cause of disability worldwide. Within the multifaceted pathophysiology of migraine, hormonal fluctuations play an evident triggering and exacerbating role, pointing toward the need for identification and proper usage of both existing and new hormonal targets in migraine treatment.

AREAS COVERED

With a threefold higher incidence of migraine in women than in men, the authors delve into sex hormone-related events in migraine patients. A comprehensive overview is given of existing hormonal therapies, including oral contraceptives, intrauterine devices, transdermal and subcutaneous estradiol patches, gnRH-agonists, oral testosterone, and 5α reductase inhibitors. The authors discuss their effectiveness and risks, noting their suitability for different patient profiles. Next, novel evolving hormonal treatments, such as oxytocin and prolactin, are explored. Lastly, the authors cover hormonal conditions associated with migraine, such as polycystic ovary syndrome, endometriosis, and transgender persons receiving gender affirming hormone therapy, aiming to provide more personalized and effective solutions for migraine management.

EXPERT OPINION

Rigorous research into both existing and new hormonal targets, as well as the underlying pathophysiology, is needed to support a tailored approach in migraine treatment, in an ongoing effort to alleviate the impact of migraine on individuals and society.

Efficacy of Onabotulinum Toxin A on Obsessive–Compulsive Traits in a Population of Chronic Migraine Patients

Background: Drug addiction may play an important role in chronic migraine (CM) with medication-overuse headache (MOH). Psychiatric diseases are associated with CM, but data regarding obsessive–compulsive disorder (OCD) are lacking. We aimed to establish the prevalence of OCD traits in CM patients with MOH and the impact on onabotulinum toxin A (OBT-A) treatment. Methods: A total of 75 patients with CM and MOH undergoing treatment with OBT-A in our Headache Centre were evaluated. At baseline and after four injection sessions, we assessed the migraine burden and the presence of OCD traits with the Obsessive–Compulsive Inventory—Revised (OCI-R) test. Results: At baseline, 28% of patients had OCI-R scores compatible with borderline OCD aspects, while 22.7% were pathological. An improvement in headache was significantly associated with an increase in the number of subjects with a normal OCI-R score at T0 and T1, whereas patients with a pathological OCI-R score at T0 showed a significantly higher prevalence of CM at T1. Conclusions: Our data showed a significant rate of OCD traits at baseline, which could strengthen the hypothesis of an addictive disorder underlying CM with MOH. OCD traits seem to influence the OBT-A response. An OCD assessment could be useful in improving patients’ selections before starting treatments.

Nomogram for Postoperative Headache in Adult Patients Undergoing Elective Cardiac Surgery

Background Postoperative headache (POH) is frequent after cardiac surgery; however, few studies on risk factors for POH exist. The aims of the current study were to explore risk factors related to POH after elective cardiac surgery and to establish a predictive system. Methods and Results Adult patients undergoing elective open-heart surgery under cardiopulmonary bypass from 2016 to 2020 in 4 cardiac centers were retrospectively included. Two thirds of the patients were randomly allocated to a training set and one third to a validation set. Predictors for POH were selected by univariate and multivariate analysis. POH developed in 3154 of the 13 440 included patients (23.5%) and the overall mortality rate was 2.3%. Eight independent risk factors for POH after elective cardiac surgery were identified, including female sex, younger age, smoking history, chronic headache history, hypertension, lower left ventricular ejection fraction, longer cardiopulmonary bypass time, and more intraoperative transfusion of red blood cells. A nomogram based on the multivariate model was constructed, with reasonable calibration and discrimination, and was well validated. Decision curve analysis revealed good clinical utility. Finally, 3 risk intervals were divided to better facilitate clinical application. Conclusions A nomogram model for POH after elective cardiac surgery was developed and validated using 8 predictors, which may have potential application value in clinical risk assessment, decision-making, and individualized treatment associated with POH.

Migraine: A Review on Its History, Global Epidemiology, Risk Factors, and Comorbidities

Migraine affects more than one billion individuals each year across the world, and is one of the most common neurologic disorders, with a high prevalence and morbidity, especially among young adults and females. Migraine is associated with a wide range of comorbidities, which range from stress and sleep disturbances to suicide. The complex and largely unclear mechanisms of migraine development have resulted in the proposal of various social and biological risk factors, such as hormonal imbalances, genetic and epigenetic influences, as well as cardiovascular, neurological, and autoimmune diseases. This review presents a comprehensive review of the most up-to-date literature on the epidemiology, and risk factors, as well as highlighting the gaps in our knowledge.

Incidence, Risk Factors and Outcomes of Postoperative Headache After Stanford Type a Acute Aortic Dissection Surgery

Background: Postoperative headache (POH) is common in clinical practice, however, no studies about POH after Stanford type A acute aortic dissection surgery (AADS) exist. This study aims to describe the incidence, risk factors and outcomes of POH after AADS, and to construct two prediction models.

Methods: Adults who underwent AADS from 2016 to 2020 in four tertiary hospitals were enrolled. Training and validation sets were randomly assigned according to a 7:3 ratio. Risk factors were identified by univariate and multivariate logistic regression analysis. Nomograms were constructed and validated on the basis of independent predictors.

Results: POH developed in 380 of the 1,476 included patients (25.7%). Poorer outcomes were observed in patients with POH. Eight independent predictors for POH after AADS were identified when both preoperative and intraoperative variables were analyzed, including younger age, female sex, smoking history, chronic headache history, cerebrovascular disease, use of deep hypothermic circulatory arrest, more blood transfusion, and longer cardiopulmonary bypass time. White blood cell and platelet count were also identified as significant predictors when intraoperative variables were excluded from the multivariate analysis. A full nomogram and a preoperative nomogram were constructed based on these independent predictors, both demonstrating good discrimination, calibration, clinical usefulness, and were well validated. Risk stratification was performed and three risk intervals were defined based on the full nomogram and clinical practice.

Conclusions: POH was common after AADS, portending poorer outcomes. Two nomograms predicting POH were developed and validated, which may have clinical utility in risk evaluation, early prevention, and doctor-patient communication.

Predictors and nomogram models for postoperative headache in patients undergoing heart valve surgery

Background

Headache is a frequent complication after cardiac surgery. However, studies on the risk factors of postoperative headache (POH) are rare. The purpose of this study was to identify independent risk factors for POH in patients undergoing heart valve surgery (HVS) and to develop and validate risk prediction models.

Methods

Consecutive patients undergoing open HVS from 2016 to 2019 were enrolled in this study. Patients were randomly assigned to training and validation sets at a 2:1 ratio. Univariate and multivariate analysis were applied to identify independent predictors for POH in the training set. A nomogram predicting POH was developed based on these factors, and was validated in the independent validation set.

Results

POH developed in 1,061 of the 3,853 patients (27.5%). The overall mortality was 2.9%, and it was significantly higher in patients with POH (4.3% versus 2.4%, P<0.001). In the training set, six independent predictors were identified by multivariate analysis, including female, smoking history, hypertension, headache history, left ventricular ejection fraction, and cardiopulmonary bypass time. The model demonstrated good discrimination in both the training (c-index: 0.811) and validation sets (c-index: 0.814), and calibration was assessed by visual inspection. A second nomogram was also constructed including only preoperative predictors, with good discrimination (c-index: 0.792) and calibration. The decision and clinical impact curves of the models showed good clinical utility.

Conclusions

We developed and validated two risk prediction models for POH in patients undergoing HVS. The models may have clinical utility in individualized risk assessment and preventive interventions.

Association of Migraine With Incident Hypertension After Menopause: A Longitudinal Cohort Study

OBJECTIVE

Migraine has been identified as a potential risk factor for hypertension in prospective studies. In women, migraine prevalence decreases after menopause, but no studies have determined whether migraine is associated with hypertension after menopause. This study sought to determine whether history of migraine was associated with an increased risk of hypertension among menopausal women.

METHODS

We assessed associations between migraine and hypertension in a longitudinal cohort study of 56,202 menopausal women participating in the French E3N cohort, with follow-up beginning in 1993. We included women who did not have hypertension or cardiovascular disease at the time of menopause. Migraine was classified as ever or never at each questionnaire cycle. Cox proportional hazards models were used to investigate relations between migraine and hypertension, controlling for potential confounding. A secondary analysis with baseline in 2011 considered aura status, grouping participants reporting migraine as migraine with aura, migraine without aura, or unknown migraine type.

RESULTS

During 826,419 person-years, 12,501 cases of incident hypertension were identified, including 3,100 among women with migraine and 9,401 among women without migraine. Migraine was associated with an increased risk of hypertension in menopausal women (hazard ratio [HR]_migraine 1.29 [95% confidence interval 1.24, 1.35]) and was consistent in post hoc sensitivity analyses, such as when controlling for common migraine medications. Associations between migraine and hypertension were similar whether or not women reported aura (HR_{migraine aura} 1.54 [1.04, 2.30], HR_{migraine no aura} 1.32 [0.87, 2.02], p heterogeneity 0.60). Associations were slightly stronger among ever users of menopausal hormone therapy (HR_migraine 1.34 [1.27, 1.41]) than among never users (HR_migraine 1.19 [1.11, 1.28]).

CONCLUSIONS

Migraine was associated with an increased risk of hypertension among menopausal women. In secondary analysis, we did not observe a significant difference between migraine with aura and migraine without aura.

Management of perimenopause disorders: hormonal treatment

Perimenopause represents a transition period of a woman's life during which physiological, affective, psychological, and social changes mark progression from a woman's fertile life to menopause, with wide sexual hormones fluctuations until the onset of hypergonadotropic hypogonadic amenorrhea. Contraception during menopause should not only avoid unwanted pregnancies, but also improve quality of life and prevent wide range of condition affecting this population. Hormonal contraceptives confer many noncontraceptive benefits for women approaching menopause: treatment of abnormal uterine bleeding, relief from vasomotor symptoms, endometrial protection in women using estrogen therapy, musculoskeletal protection, and mood disorders protection. The main point remains selecting the most adequate contraceptive option for each woman, considering her risk factor, comorbidities, and keeping in mind the possibility of continuing contraception until reaching menopause and even further, creating a bridge between perimenopause and menopause hormonal therapy. Correct perimenopause management should rely on individualized medical therapy and multidisciplinary approach considering lifestyle and food habits as part of general good health of a woman.

Giving Researchers a Headache - Sex and Gender Differences in Migraine

Migraine is a common neurovascular disorder affecting ~15% of the general population. Ranking second in the list of years lived with disability (YLD), people living with migraine are greatly impacted by this especially burdensome primary headache disorder. In ~30% of individuals with migraine, transient neurological symptoms occur (migraine aura) that further increase migraine burden. However, migraine burden is differential with respect to sex. Though one-year prevalences in childhood are similar, starting with puberty, migraine incidence increases at a much higher rate in females than males. Thus, migraine over the life course occurs in women three to four times more often than in men. Attacks are also more severe in women, leading to greater disability and a longer recovery period. The sex disparity in migraine is believed to be partly mediated through fluctuations in ovarian steroid hormones, especially estrogen and progesterone, although the exact mechanisms are not yet completely understood. The release of the neuropeptide calcitonin gene-related peptide (CGRP), followed by activation of the trigeminovascular system, is thought to play a key role in the migraine pathophysiology. Given the burden of migraine and its disproportionate distribution, the underlying cause(s) for the observed differences between sexes in the incidence, frequency, and intensity of migraine attacks must be better understood. Relevant biological as well as behavioral differences must be taken into account. To evaluate the scope of the existing knowledge on the issue of biological sex as well as gender differences in migraine, we conducted a systematized review of the currently available research. The review seeks to harmonize existing knowledge on the topic across the domains of biological/preclinical, clinical, and population-level research, which are traditionally synthesized and interpreted in isolation. Ultimately, we identify knowledge gaps and set priorities for further interdisciplinary and informed research on sex and gender differences as well as gender-specific therapies in migraine.
