Global Burden of Mental, Neurological & Substance Use Disorders

Below:  Absolute Disability-adjusted life years (DALYs) Attributable to Mental, Neurological, and Substance Use Disorders, by Age, 2010

Below:  Age-Standardized DALY Rates Attributable to Mental, Neurological, and Substance Use Disorders, by Region

Below:  Proportion of Global YLDs and YLLs Attributable to Mental, Neurological, and Substance Use Disorders, 2010

Results
In 2010, mental, neurological and substance use disorders accounted for 10.4% of global DALYs, 2.3% of global YLLs and, 28.5% of global YLDs, making them the leading cause of YLDs. Mental disorders accounted for the largest proportion of DALYs (56.7%), followed by neurological disorders (28.6%) and substance use disorders (14.7%). DALYs peaked in early adulthood for mental and substance use disorders but were more consistent across age for neurological disorders. Females accounted for more DALYs in all mental and neurological disorders, except for mental disorders occurring in childhood, schizophrenia, substance use disorders, Parkinson’s disease and epilepsy where males accounted for more DALYs. Overall DALYs were highest in Eastern Europe/Central Asia and lowest in East Asia/the Pacific.

Conclusion
Mental, neurological and substance use disorders contribute to a significant proportion of disease burden. Health systems can respond by implementing established, cost effective interventions, or by supporting the research necessary to develop better prevention and treatment options.
