Global Mental Health Crisis, Democratic Decline, and Emerging Scientific Insights
The Expanding Global Mental Health Burden
Mental disorders have significantly increased worldwide, doubling since 1990 and now representing the leading cause of disability globally. This shift surpasses the impact of cancer and cardiovascular diseases. The heaviest burden of these disorders is observed among young adults aged 15-19, with women experiencing higher rates than men.
Erosion of Democratic Systems Worldwide
A recent analysis of V-Dem data indicates a concerning global trend of democratic decline. Currently, autocracies outnumber democracies (92 to 87), and the rate of countries transitioning towards autocracy is higher than those moving towards democracy (44 to 18). Notably, the United States under the Trump administration is experiencing a period of rapid democratic dismantling, considered unprecedented in modern history.
