The burden of headache disorders among adults in Peru: national estimates and a health-care needs assessment from a population-based door-to-door survey.

Background: We have previously found that almost two thirds (64.6%) of adults in Peru have an active headache disorder. Here, using data from the same sample, we present attributed burden at individual and population levels.

Cost of illness and labour market disaffiliation among patients with migraine discontinuing triptan treatment: A Danish nationwide register study from 1995 to 2021.

Background: Migraine presents significant health and economic challenges. Despite the widespread use of triptans, some patients discontinue them because of insufficient relief or adverse effects. Using national registers, the present study investigates the excess costs and labour market disaffiliation of Danish patients discontinuing triptan treatment.

The burden of headache disorders in the adult population of Mongolia: estimates, and a health-care needs assessment, from a cross-sectional population-based study.

Background: Having previously shown headache disorders to be prevalent in Mongolia, here we elaborate on headache as a public-health concern in this country, reporting symptom burden and headache-attributed impaired participation at individual and societal levels, and conducting a health-care needs assessment.

Methods: The study followed the standardized methodology developed by the Global Campaign against Headache, generating a representative general-population sample through multi-level randomized cluster sampling. Participants aged 18-65 years were interviewed at unannounced household visits by interviewers administering the HARDSHIP questionnaire.

Migraine is the most disabling neurological disease among children and adolescents, and second after stroke among adults: A call to action.

The Global Burden of Disease (GBD) study is pivotal in shaping health policies by providing comprehensive data on mortality and disability. An updated GBD2021 analysis, published in on 14 March 2024, expands the scope of neurological disorders to include 37 conditions, revealing their significant impact on global health. Neurological disorders affect 3.

The prevalence of headache disorders in children and adolescents in Benin: a schools-based study.

Background: A global schools-based programme within the Global Campaign against Headache is estimating the burden of headache in children (6-11 years) and adolescents (12-17 years), cluster-sampling the world by conducting national studies in all world regions. Its purpose is to complement population-based studies in adults, adding to knowledge of the burden of headache and informing educational and health policies. This study in Benin was the third in the programme from sub-Saharan Africa (SSA).

The burdens attributable to headache disorders in Cameroon: national estimates from a population-based door-to-door survey, including a headache-care needs assessment.

Background: We have previously shown headache to be highly prevalent in Cameroon. Here we present the attributed burden. We also perform a headache-care needs assessment.

Cost of transport is a barrier to access to headache care in sub-Saharan Africa: An observational study in an HIV-positive population.

Introduction: Headache disorders are the largest contributor to all years lived with disability attributed to neurological disorders. In sub-Saharan Africa (SSA), with 1.2 billion inhabitants, headache prevalence is similar to that of Western countries but with widely inadequate access to care.

Headache prevalence and demographic associations in the Delhi and National Capital Region of India: estimates from a cross-sectional nationwide population-based study.

Background: India is a large and populous country where reliable data on headache disorders are relatively scarce. This study in northern India (Delhi and National Capital Territory Region [NCR], including surrounding districts in the States of Haryana, Uttar Pradesh and Rajasthan) continues the series of population-based studies within the Global Campaign against Headache and follows an earlier study, using the same protocol and questionnaire, in the southern State of Karnataka.

Methods: This cross-sectional study used the Global Campaign's established methodology.

The burden of headache and a health-care needs assessment in the adult population of Mali: a cross-sectional population-based study.

Background: Our recent studies have shown headache disorders to be very common in the central and western sub-Saharan countries of Benin and Cameroon. Here we report headache in nearby Mali, a strife-torn country that differs topographically, culturally, politically and economically. The purposes were to estimate headache-attributed burden and need for headache care.

The burdens attributable to primary headache disorders in children and adolescents in Iran: estimates from a schools-based study.

Background: We recently found headache disorders to be highly prevalent among children (aged 6-11 years) and adolescents (aged 12-17) in Iran (gender- and age-adjusted 1-year prevalences: migraine 25.2%, tension-type headache 12.7%, undifferentiated headache [UdH] 22.

Australian Headache Epidemiology Data (AHEAD): a pilot study to assess sampling and engagement methodology for a nationwide population-based survey.

Background: There are no robust population-based Australian data on prevalence and attributed burden of migraine and medication-overuse headache (MOH) data. In this pilot cross-sectional study, we aimed to capture the participation rate, preferred response method, and acceptability of self-report questionnaires to inform the conduct of a future nationwide migraine/MOH epidemiological study.

Methods: We developed a self-report questionnaire, available in hard-copy and online, including modules from the Headache-Attributed Restriction, Disability, Social Handicap and Impaired Participation (HARDSHIP) questionnaire, the Eq.

The burden of headache disorders in the adult general population of the Kingdom of Saudi Arabia: estimates from a cross-sectional population-based study including a health-care needs assessment.

Background: We have previously shown headache to be highly prevalent among adults in Saudi Arabia. Here we estimate associated symptom burden and impaired participation (impaired use of time, lost productivity and disengagement from social activity), and use these estimates to assess headache-related health-care needs in Saudi Arabia.

Methods: A randomised cross-sectional survey included 2,316 adults (18-65 years) from all 13 regions of the country.

The prevalence and demographic associations of headache in the adult population of Benin: a cross-sectional population-based study.

Background: The Global Burden of Disease (GBD) study is increasingly well informed with regard to headache disorders, but sub-Saharan Africa (SSA) remains one of the large regions of the world with limited data directly derived from population-based studies. The Global Campaign against Headache has conducted three studies in this region: Ethiopia in the east, Zambia in the south and Cameroon in Central SSA. Here we report a similar study in Benin, the first from West SSA.

The prevalence and demographic associations of headache in the adult population of Peru: a national cross-sectional population-based study.

Background: The Global Campaign against Headache is conducting a series of population-based studies to fill the large geographical gaps in knowledge of headache prevalence and attributable burden. One major region not until now included is South America. Here we present a study from Peru, a country of 32.

The prevalence of headache in the adult population of Morocco: a cross-sectional population-based study.

Background: The series of population-based studies conducted by the Global Campaign against Headache has, so far, included Pakistan and Saudi Arabia from the Eastern Mediterranean Region. The Maghreb countries of North Africa, also part of this Region, are geographically apart and culturally very different from these countries. Here we report a study in Morocco.

The burden attributable to primary headache disorders in children and adolescents in Ethiopia: estimates from a national schools-based study.

Background: We previously reported high prevalences of headache disorders among children (6-11 years) and adolescents (12-17 years) in Ethiopia. Here we provide data on headache-attributed burden collected contemporaneously from the same study participants. Part of the global schools-based programme within the Global Campaign against Headache, the study is the first to present such data from sub-Saharan Africa.

Headache in the adult population of Cameroon: prevalence estimates and demographic associations from a cross-sectional nationwide population-based study.

Background: Knowledge of headache prevalence, and the burdens attributable to headache disorders, remains incomplete in sub-Saharan Africa (SSA): reliable studies have been conducted only in Zambia (southern SSA) and Ethiopia (eastern SSA). As part of the Global Campaign against Headache, we investigated the prevalence of headache in Cameroon, in Central SSA.

Methods: We used the same methodology as the studies in Zambia and Ethiopia, employing cluster-randomized sampling in four regions of Cameroon, selected to reflect the country's geographic, ethnic and cultural diversities.

The burden of headache disorders in North India: methodology, and validation of a Hindi version of the HARDSHIP questionnaire, for a community-based survey in Delhi and national capital territory region.

Background: Knowledge of the prevalence and attributable burden of headache disorders in India is sparse, with only two recent population-based studies from South and East India. These produced conflicting results. A study in North India is needed.

Premonitory symptoms in migraine: A REFORM Study.

Background: Estimates of proportions of people with migraine who report premonitory symptoms vary greatly among previous studies. Our aims were to establish the proportion of patients reporting premonitory symptoms and its dependency on the enquiry method. Additionally, we investigated the impact of premonitory symptoms on disease burden using Headache Impact Test (HIT-6), Migraine Disability Assessment (MIDAS) and World Health Organization Disability Assessment 2.

The World Health Organization Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders and the headache revolution: from headache burden to a global action plan for headache disorders.

The World Health Organization (WHO) Intersectoral Global Action Plan on Epilepsy and Other Neurological Disorders was developed by WHO to address the worldwide challenges and gaps in provision of care and services for people with epilepsy and other neurological disorders and to ensure a comprehensive, coordinated response across sectors to the burden of neurologic diseases and to promote brain health across life-course. Headache disorders constitute the second most burdensome of all neurological diseases after stroke, but the first if young and midlife adults are taken into account. Despite the availability of a range of treatments, disability associated with headache disorders, and with migraine, remains very high.

What proportion of people with migraine report postdromal symptoms? A systematic review and meta-analysis of observational studies.

Background: Postdromal symptoms, following headache resolution, are said to constitute a distinct phase of the migraine attack. We question the evidence for this, with regard both to the nature of such symptoms and to how often they are reported to occur.

Methods: We searched the Pubmed and Embase databases for relevant articles from their inception until 25 May 2023.

Migraine in older adults.

Migraine is an evolving, and sometimes lifelong disorder. The prevalence of episodic migraine peaks among individuals aged in their late 30s, implying a tendency for the disorder to remit with increasing age thereafter, whereas chronic migraine is more likely to persist into later life. Diagnosis and treatment of migraine in older adults, defined as individuals aged 60 years or older, is rendered more complex by increasing probabilities of atypical clinical features and comorbidities, with patients' comorbidities sometimes limiting their therapeutic options.
