Cephalalgia : an international journal of headache

With a recognition that the management of headache remains far from ideal, there may be more immediate potential to reduce the burden of illness from developments in the delivery of headache services. There is a paucity of evidence in this area and a danger that an expanding research agenda will be dominated by inappropriate methodological frameworks that have been so successful in developing medical treatments. The prevailing scientific methods are underpinned by statistical approaches that are aggregative in nature and assume independence of system elements, an approach that may have limited utility in the analysis of complex systems such as headache care delivery. This review calls for a shift in headache research resources to organizational development and briefly outlines alternative methodological considerations.

A recent population-based prospective study reported that in women, migraine with aura (MA), but not migraine without aura (MoA), was associated with increased risk of coronary heart disease events (CHD). We sought to confirm this association in an Australian population-based cohort of older men and women (n = 2331, aged 49-97 years). We defined MA and MoA from face-to-face interview using International Headache Society criteria. ⋯ In women, a history of MA was associated with a non-significant twofold higher risk of CHD death (age-adjusted relative risk 2.2, 95% confidence interval 0.8, 5.8, P = 0.11), which remained similar after adjustment for cardiovascular risk factors. There were no CHD deaths in men with a history of migraine. Our findings support reports that in women, MA, but not MoA, may be associated with increased risk of CHD.

This population-based cross-sectional study examined the 3-month prevalence of headache, migraine and tension-type headache (TTH) among adolescents aged 12-15 years in Germany. Students (n = 3324) from 20 schools completed a questionnaire on general and headache-specific pain which included a sociodemographic module. The headache-specific questionnaire complied with the respective revised criteria of the International Headache Society (IHS). 'Modified criteria' changed the item 'duration' in migraine (>30 min instead of > 4 h). ⋯ The 3-month prevalence of migraine was 2.6% (boys 1.6%, girls 3.5%) applying strict IHS criteria and 6.9% (boys 4.4%, girls 9.3%) with modified criteria; 12.6% (boys 8.3%, girls 16.7%) suffered from probable migraine, 0.07% fulfilled the criteria for chronic migraine, 4.5% (boys 4.6%, girls 4.3%) suffered from TTH, 0.2% from chronic TTH and 15.7% (boys 14.5%, girls 16.9%) from probable TTH. Headache and migraine were more common in girls than in boys and in teenagers, especially in girls, aiming at higher education. Recurrent headache and primary headache disorders are common complaints among German adolescents, especially among girls.
