[Editorial] The shared burden of stroke and dementia (Lancet Neurology)

The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) has enabled researchers to understand the epidemiology of global health in a systematic way that has not been possible before. Collaborators of the GBD, with funding from the Bill & Melinda Gates Foundation, collate global epidemiological data to generate estimates of mortality and morbidity, which are presented by age, sex, region, and economic status. The most recent overall GBD update, published in The Lancet, provided estimates of the years lived with disability for many neurological diseases, but did not assess the contribution of associated risk factors to disability burden.
