Mental health conditions contribute to 290 million disability-adjusted life years (DALYs), but they only receive approximately 2 percent spending on healthcare by governments around the world. Addressing the $200 billion to $350 billion mental health investment gap can have a transformative potential on the global noncommunicable diseases (NCD) epidemic and economy. McKinsey Health Institute (MHI) analysis finds that implementing and scaling proven mental health interventions globally by 2050 could reduce direct and indirect mental health disease burden by over 40 percent. Furthermore, every dollar invested in expanding these interventions has the potential to generate an economic return of $5 to $6 in GDP growth globally.
