Abstract

Abstract Body

Background: Neurological disorders are increasingly recognized as major causes of death and disability worldwide. The Global Burden of Disease Study 2016 (GBD 2016) is the most comprehensive and up-to-date effort to measure global, regional, and national burden from all causes of death and disability.

Methods: Using the GBD methodology we estimated prevalence, death, years of life lost (YLL), years lived with disability (YLD), and disability-adjusted life years (DALYs) by age and sex for 15 neurological disorders in 195 countries from 1990 to 2016. Each location was grouped into one of five quintiles based on its Socio-demographic Index (SDI) value in 2016.

Results: Globally, in 2016 neurological disorders were the leading cause of DALYs (276 [247-306] million) and second leading cause of deaths (9.0 [8.8-9.4] million). Although age-standardised rates of neurological disorders have declined or remained stable from 1990 to 2016, the absolute number of people affected increased significantly (except for infectious neurological disorders). The four largest contributors of neurological DALYs were stroke (42.2% [38.6-46.1]), migraine (16.2% [11.7-20.8]), Alzheimer’s and other dementias (10.4% [9.0-12.1]), and meningitis (7.9% [6.6-10.4]).

Conclusion: The burden of neurological disorders continues to increase in every country of the world. As populations are growing and aging, and the prevalence of major disabling neurological disorders steeply increases with age, governments will face increasing demand for treatment, rehabilitation, and support services for neurological disorders.

Abstract

Abstract Body

Neurological disorders are a leading cause of disability-adjusted life years (DALYs), the sum of years of life lost (YLLs) and years lived with disability (YLDs). In 2016, the four largest contributors of neurological DALYs were stroke (42·2%), migraine (16·3%), dementia (10·4%) and meningitis (7·9%). In the period 1990-2016 the total number of deaths and DALYs due to neurological disorders increased by 39% and 15% while the corresponding age-standardized rates decreased by 28% and 27%. As the socio-demographic index (SDI), the measure of the social and economic status of a population, is highly correlated with health outcomes, the decrease of age-standardized rates can be a reflection of the worldwide SDI increase. However, the growth of the world population (mostly due to better sanitation and perinatal care) and the aging process itself (with consequent increase of aging-related diseases) explain the increase in neurological DALYs. This increase can have a significant impact on health-care systems, posing a challenge to the their sustainability. Low-income countries with rapid transitions can now have burden profiles dominated by non-communicable diseases. With time, DALYs have increasingly arisen from YLDs. Functional health loss is caused by stroke survivors and the increasing number of individuals with age-related neurodegenerative diseases. In the absence of effective treatments, the reversal of these negative trends should be based on the control of preventable risk factors (hypertension, hyperglycemia, high BMI, ambient pollution, alcohol and drug abuse). The reversal of exposure to these risks could strongly reduce the impact of neurological diseases on health-care systems.
