Summary Background Stroke is a leading cause of mortality and disability worldwide and the economic costs of treatment and post-stroke care are substantial. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) provides a systematic, comparable method of quantifying health loss by disease, age, sex, year, and location to provide information to health systems and policy makers on more than 300 causes of disease and injury, including stroke. The results presented here are the estimates of burden due to overall stroke and ischaemic and haemorrhagic stroke from GBD 2016. Methods We report estimates and corresponding uncertainty intervals (UIs), from 1990 to 2016, for incidence, prevalence, deaths, years of life lost (YLLs), years lived with disability (YLDs), and disability-adjusted life-years (DALYs). DALYs were generated by summing YLLs and YLDs. Cause-specific mortality was estimated using an ensemble modelling process with vital registration and verbal autopsy data as inputs. Non-fatal estimates were generated using Bayesian meta-regression incorporating data from registries, scientific literature, administrative records, and surveys. The Socio-demographic Index (SDI), a summary indicator generated using educational attainment, lagged distributed income, and total fertility rate, was used to group countries into quintiles. Findings In 2016, there were 5·5 million (95% UI 5·3 to 5·7) deaths and 116·4 million (111·4 to 121·4) DALYs due to stroke. The global age-standardised mortality rate decreased by 36·2% (−39·3 to −33·6) from 1990 to 2016, with decreases in all SDI quintiles. Over the same period, the global age-standardised DALY rate declined by 34·2% (−37·2 to −31·5), also with decreases in all SDI quintiles. There were 13·7 million (12·7 to 14·7) new stroke cases in 2016. Global age-standardised incidence declined by 8·1% (−10·7 to −5·5) from 1990 to 2016 and decreased in all SDI quintiles except the middle SDI group. There were 80·1 million (74·1 to 86·3) prevalent cases of stroke globally in 2016; 41·1 million (38·0 to 44·3) in women and 39·0 million (36·1 to 42·1) in men. Interpretation Although age-standardised mortality rates have decreased sharply from 1990 to 2016, the decrease in age-standardised incidence has been less steep, indicating that the burden of stroke is likely to remain high. Planned updates to future GBD iterations include generating separate estimates for subarachnoid haemorrhage and intracerebral haemorrhage, generating estimates of transient ischaemic attack, and including atrial fibrillation as a risk factor.

Background and Purpose-There is mounting evidence of endothelial activation and dysfunction in migraine. Our objectives were to determine in a population of premenopausal women whether endothelial activation markers are associated with migraine. Methods-Women (18 to 50 years) with and without migraine and free from cardiovascular disease were evaluated with tests of coagulation (von Willebrand factor activity, prothrombin fragment), fibrinolysis (tissue-type plasminogen activator antigen), inflammation (high-sensitivity C-reactive protein), and oxidative stress (homocysteine, total nitrate/nitrite concentrations, thiobarbituric acid-reactive substances). Results-Sixty-one participants had migraine with aura (MA), 64 had migraine without aura (MO), and 50 were controls.Compared with controls, women with migraine had higher adjusted odds ratios for elevated von Willebrand factor activity of 6.51 (95% CI,

Objectives.-To examine the prevalence of childhood maltreatment and adult revictimization in migraineurs and the association with sociodemographic factors, depression and anxiety.Background.-Population and practice-based studies have demonstrated an association of childhood abuse and headache in adults, although further details on headache diagnoses, characteristics, and comorbid conditions are lacking. There are mounting data suggesting substantial impact of early maltreatment on adult physical and mental health.Methods.-Electronic surveys were completed by patients seeking treatment in 11 headache centers across the United States and Canada. Physicians determined the primary headache diagnoses based on the International Classification of Headache Disorders-2 criteria and average monthly headache frequency. Self-reported information on demographics (including body mass index), social history, and physician-diagnosed depression and anxiety was collected. The survey also included validated screening measures for current depression (Patient Health Questionnaire-9) and anxiety (The Beck Anxiety Inventory). History and severity of childhood (<18 years) abuse (sexual, emotional, and physical) and neglect (emotional and physical) was gathered using the Childhood Trauma Questionnaire. There were also queries regarding adult physical and sexual abuse, including age of occurrence. Analysis includes all persons with migraine with aura, and migraine without aura.Results.-A total of 1348 migraineurs (88% women) were included (mean age 41 years). Diagnosis of migraine with aura was recorded in 40% and chronic headache (Ն15 days/month) was reported by 34%. The prevalence of childhood maltreatment types was as follows: physical abuse 21%, sexual abuse 25%, emotional abuse 38%, physical neglect 22%, and emotional neglect 38%. Nine percent reported all 3 categories of childhood abuse (physical, sexual, and emotional) and 17% reported both physical and emotional neglect. Overlap between maltreatment types ranged between 40% and 81%. Of those reporting childhood abuse, 43% reported abuse in adulthood, but infrequently (17%) over the age of 30 years. In logistic regression models adjusted for sociodemographic variables, current depression was associated with physical (P = .003), sexual (P = .007), and emotional abuse (P < .001), and physical and emotional neglect (P = .001 for both). Current anxiety was also associated with all childhood abuse and neglect categories (P < .001 for all). A graded relationship was observed between the number of childhood maltreatment types and remote or current depression and anxiety. In adjusted logistic regression analysis, migraineurs reporting 3 or more categories of childhood trauma were more likely to have received diagnoses of both depression From the University of Toledo, Toledo, OH, USA

Symptoms of CA in migraine were associated with current anxiety, depression, and several chronic pain conditions. A graded relationship was observed between number of allodynic symptoms and the number of pain conditions, even after adjusting for confounding factors. This study also presents the novel association of CA symptoms with younger age of migraine onset, and with cigarette smoking, in addition to confirming several previously reported findings.
