To assess the self-perception of MFs in patients with migraine (PWM) compared to patients with epilepsy (PWE) with a standardized protocol in different countries. Transcultural multicenter comparative cross-sectional study.

Annual indirect costs secondary to headache disability in Brazil.

Background: Disability imposed by headache disorders constitutes an expressive economic burden, mostly from indirect costs due to absenteeism and presenteeism.

Objective: To estimate indirect costs from absenteeism and presenteeism due to headache disorders in Brazil.

Methods: In a secondary, descriptive analysis of two nationwide databases, we estimated indirect costs based on headache-related disability and socioeconomic data.

Recommendations for the treatment of migraine attacks - a Brazilian consensus.

In this article, a group of experts in headache management of the Brazilian Headache Society developed through a consensus strategic measurements to treat a migraine attack in both the child and the adult. Particular emphasis was laid on the treatment of migraine in women, including at pregnancy, lactation and perimenstrual period.

The prevalence and impact of headache in Brazil.

Background/objectives: In Brazil, several epidemiological studies on headache have been produced, most with an emphasis on prevalence and the association of primary headaches with some sociodemographic characteristics of the population. Data on the burden of headache, however, are scarce. The aim of this paper is to review all Brazilian population-based studies on headache, as well as to analyze the Migraine Disability Assessment Score (MIDAS) data collected with the PhD thesis of the senior author (LPQ).

Headache classification and aspects of reproductive life in young women.

Objective: To classify headaches as a function of the menstrual cycle and to contrast aspects relating to the reproductive cycle as a function of headache type.

Method: Participants responded to a structured questionnaire consisting of 44 questions. Detailed headache information, enabling the classification of headaches, and questions relating to the menstrual cycle were obtained.

The methodology of population surveys of headache prevalence, burden and cost: principles and recommendations from the Global Campaign against Headache.

The global burden of headache is very large, but knowledge of it is far from complete and needs still to be gathered. Published population-based studies have used variable methodology, which has influenced findings and made comparisons difficult. Among the initiatives of the Global Campaign against Headache to improve and standardize methods in use for cross-sectional studies, the most important is the production of consensus-based methodological guidelines.

Diagnosis, prevalence estimation and burden measurement in population surveys of headache: presenting the HARDSHIP questionnaire.

The global burden of headache is very large, but knowledge of it is far from complete and needs still to be gathered. Published population-based studies have used variable methodology, which has influenced findings and made comparisons difficult. The Global Campaign against Headache is undertaking initiatives to improve and standardize methods in use for cross-sectional studies.

Improving quality in population surveys of headache prevalence, burden and cost: key methodological considerations.

Population-based studies of headache disorders are important. They inform needs assessment and underpin service policy for a set of disorders that are a public-health priority. On the one hand, our knowledge of the global burden of headache is incomplete, with major geographical gaps; on the other, methodological differences and variable quality are notable among published studies of headache prevalence, burden and cost.

Latin American consensus on guidelines for chronic migraine treatment.

Chronic migraine is a condition with significant prevalence all around the world and high socioeconomic impact, and its handling has been challenging neurologists. Developments for understanding its mechanisms and associated conditions, as well as that of new therapies, have been quick and important, a fact which has motivated the Latin American and Brazilian Headache Societies to prepare the present consensus. The treatment of chronic migraine should always be preceded by a careful diagnosis review; the detection of possible worsening factors and associated conditions; the stratification of seriousness/impossibility to treat; and monitoring establishment, with a pain diary.

Worldwide epidemiology of fibromyalgia.

Studying the epidemiology of fibromyalgia (FM) is very important to understand the impact of this disorder on persons, families and society. The recent modified 2010 classification criteria of the American College of Rheumatology (ACR), without the need of tender points palpation, allows that larger and nationwide surveys may be done, worldwide. This article reviews the prevalence and incidence studies done in the general population, in several countries/continents, the prevalence of FM in special groups/settings, the association of FM with some sociodemographic characteristics of the population, and the comorbidity of FM with others disorders, especially with headaches.

Unusual headache syndromes.

Objective/background: Some headache syndromes have few cases reported in the literature. Their clinical characteristics, pathogenesis, and treatment may have not been completely defined. They may not actually be uncommon but rather under-recognized and/or underreported.

Characteristics of migraine visual aura in Southern Brazil and Northern USA.

Background: Migraine aura, made up of one or more neurological symptoms arising from the cortex or brainstem, is a complex neurological phenomenon. Visual aura is the most frequent aura manifestation. Studying the subjective components of visual aura makes it possible to identify common characteristics.

Headache among mesial temporal lobe epilepsy patients: a case-control study.

Epilepsy and headache are two chronic disorders that are characterized by recurrent attacks, but the relationship between them is not completely understood. Using a structured questionnaire, we investigated the prevalence of headache during the previous year in a homogeneous group of 100 patients with mesial temporal lobe epilepsy with hippocampal sclerosis (MTLE-HS). The control group consisted of 100 age-matched individuals who were randomized from a nationwide Brazilian headache database.
