Mental Health and Global Burden of Disease

Mental, neurological, and substance use disorders make a substantial contribution to the global burden of disease (GBD).[6] This is a global measure of so-called disability-adjusted life years (DALY's) assigned to a certain disease/disorder, which is a sum of the years lived with disability and years of life lost due to this disease within the total population. Neuropsychiatric conditions account for 14 % of the global burden of disease. Among non-communicable diseases, they account for 28% of the DALY's — more than cardiovascular disease or cancer. However it is estimated that the real contribution of mental disorders to the global burden of disease is even higher, amongst others due to complex interactions and co-morbidity of physical and mental illness.

Around the world, almost one million people die due to suicide every year, and it is the third leading cause of death among young people. The most important causes of disability due to health-related conditions worldwide include unipolar depression, alcoholism, schizophrenia, bipolar depression and dementia. In low- and middle-income countries, these conditions represent a total of 19.1% of all disability related to health conditions.[7]
