Abstract Background Migraine, a neurological disorder with significant female predilection, is the leading cause of disability-adjusted life years (DALYs) in women childbearing age (WCBA). There currently lack comprehensive literature analysis on overall global burden and changing trends migraines WCBA. Methods This study extracted three main indicators, including prevalence, incidence, DALYs, related to migraine WCBA from Global Burden Disease(GBD) database 1990 2021. Our presented point estimates 95% uncertainty intervals (UIs). It evaluated using estimated annual percentage change (EAPC) change. Results In 2021, DALYs cases among were 493.94 million, 33.33 18.25 respectively, changes 48%, 43%, 47% compared 1990.

Prelicinal studies and post-mortem analyses from male female human donors reveal sexual of nociceptors at transcript, protein functional levels suggesting different mechanisms that may promote pain in men women. Migraine is a common female-prevalent disorder characterized by painful debilitating headache.

Abstract Introduction Migraine is a prevalent neurological disorder causing significant disability worldwide. Despite extensive research on specific populations, comprehensive analyses of global trends are remains limited. Methods We extracted incidence, prevalence, and disability-adjusted life years (DALYs) data for migraine from the Global Burden Disease 2021 database. Trends were analyzed across regions, age groups, sexes, sociodemographic index (SDI) using estimated annual percentage changes (EAPC). Predictive models (ARIMA) used to forecast 2050. Results From 1990 2021, burden significantly increased: prevalence increased by 58.15%, 732.56 million 1.16 billion cases, incidence 42.06%. The DALYs also 58.27%.

Despite this, migraine in presents with unique characteristics terms of symptoms, treatment responses, comorbidities, pain perception. Historically, research has focused more on overlooking critical male-specific aspects. This review delves into the epidemiology, clinical presentation, particular challenges diagnosing managing men. It addresses sex-specific triggers, hormonal influences, comorbid conditions prevalence severity Additionally, evaluates current therapeutic strategies, underscoring necessity for individualized approaches. Men exhibit atypical symptoms compared to ICHD-3 criteria are likely report associated symptoms.

However, little is known about co-morbidity and To our knowledge, first prospective that systematically reviews topic. Method: Two hundred forty four referred Pediatric neurology clinic Adıyaman University Training Research Hospital between January 2021 November 2022 were examined. Gender, age, type headache, serology, other laboratory parameters cases meeting inclusion criteria recorded. Upper gastrointestinal endoscopy performed on positive serology. Patients whose results compatible placed a gluten-free diet. Results: group consisted 202 patients, 123 girls (60.9%). patients’ mean age 12.67±3.524 years. Tension-type headache determined 121 (59.9%) patient group, migraine 81 (40.1%). detected 5.4%. Vitamin B12 211±79.1 pg/ml, ferritin 19.5±13.9 ng/mL, vitamin D 17.6±9.86 ng/ml (n=193).
