Global mental illness cases nearly double in 30 years, study warns

Global cases of mental illness have climbed sharply over the past three decades. A new study reveals that 1.17 billion people suffered from mental health disorders in 2023—a near-doubling since 1990. Researchers warn that the rising trend is straining healthcare systems and demand urgent action. The study analysed data from 204 countries between 1990 and 2023. It tracked 12 types of mental disorders, including anxiety, depression, eating disorders, and schizophrenia. Overall, the total number of affected individuals has surged to around 1.2 billion.

Young women aged 15 to 19 emerged as the most vulnerable group in 2023. Conditions like anorexia, bulimia, and major depression showed particularly high rates among this demographic. The research also highlighted a broad increase across all age and gender categories.

Healthcare systems worldwide now face a growing burden, regardless of a country’s economic strength. Disorders such as dysthymia and behavioural conditions have contributed to the sharp rise. Experts attribute the spike to a mix of social, economic, and environmental pressures.

In response, researchers are calling for improved monitoring and stronger prevention measures. They stress the need for early intervention strategies to curb the escalating crisis. The findings underscore a dramatic rise in mental health disorders over 33 years. With 1.17 billion cases in 2023 alone, the pressure on global healthcare is intensifying. Authorities are now being urged to prioritise mental health support and expand access to treatment.
