“…Nevertheless, recent studies from Brazil, Chile and Ecuador show that headache is highly prevalent in these countries and imposes a large economic burden on healthcare systems stretched to their limits. As in developed countries, migraine and chronic tension-type headache are the most common subtypes of headache disorders in South America [32][33][34][35][36]. Tekle Haimanot reported that "literature on prevalence and health burden in Africa is scanty" [37].…”

[1][2][3][4][5]. A particular point at issue is whether the prevalence of headache or any particular variety of headache (e.g., migraine) varies with the nature of the society or with educa tional level and socioeconomic status.…”

Prevalence Survey of Headache in a Rural Mexican Village

et al. 1991

Prevalence of headache was studied by house-to-house survey of a small remote Mexican village where the population was characterized by a low income and high rate of illiteracy. Severe headache was found in 8.9% of the male population and in 10.6% of the females. Approximately half of these individuals gave a history suggestive of headache with aura, but reinterview by a neurologist revealed that in one third of such histories the visual phenomena were probably not true aurae. Only in the over 35-year age-group was headache more prevalent in females. ''Incapacitating'' headache was usually equated with ''severe'' headache and was 10 times as frequent in the over 55-year age-group as in younger people. Sophisticated interviewers (neurologists) obtained different results from less trained interviewers.

“…The predominant type of seizure and the percentage of treated patients also differ; in Latin America, generalized seizures are most frequent [3,6,9] , and only a minority of patients receive antiepileptic drugs (AEDs) [23] . The limited number of studies on epilepsy prevalence in Argentina revealed rates similar to those of developed countries [24,25] .…”

Background: Most studies carried out in Latin America have shown greater rates of epilepsy and generalized seizures than those observed in developed countries, in spite of lower numbers of patients receiving treatment. To date, studies in Argentina have been insufficient to establish true prevalence. Objective: To determine the prevalence of epilepsy in primary school children in Buenos Aires, together with rates of different seizure types, treatments prescribed, diagnoses made and number of inadequate therapies administered, as well as the relationship between epilepsy and learning difficulties. Design and Method: A cross-sectional study was carried out on 10% of the entire primary school population of Buenos Aires through randomized, systematic, representative and conglomerate sampling of public and private school students. A total of 26,270 responses were received (83.1% of the population) to a specially designed questionnaire, with 96.4% sensitivity and 41.5% specificity, respectively. Interviews were conducted in all probable epilepsy cases as well as in a random sample of probable negative ones. Results: Eighty-four children with epilepsy were detected (lifetime prevalence 3.2‰; active prevalence 2.6‰), in whom generalized seizures predominated (57.1%). Ninety-three percent of cases diagnosed were currently under, or had previously received antiepileptic drug (AED) therapy. Almost 1% of the primary school population studied had a prior diagnosis and/or received AED for dysrhythmia or epilepsy. The percentage of grade repeaters in the general population and in children with epilepsy was 8.4 and 26.2%, respectively. Conclusions: (1) The prevalence of epilepsy in primary school children in Buenos Aires is similar to that reported for developed countries; (2) a slight prevalence for generalized seizures was observed; (3) 93% of cases received AEDs; (4) misdiagnoses and unnecessary treatments exceeded correct diagnoses and adequate therapy, and (5) disease presence and/or treatment were associated with poorer school performance.
