Global Mental Health Burden Doubles Since 1990, Lancet Study Reveals
Mental disorders have become the leading cause of disability worldwide, according to a new study published in The Lancet. Researchers from Australia’s University of Queensland, the Queensland Center for Mental Health Research, and the University of Washington studied global mental health trends from 1990 to 2023. The report found that nearly 1.2 billion people were living with mental disorders in 2023. That number is almost double the figure recorded in 1990. Experts said anxiety and depression were the biggest contributors to the rising global mental health burden.
Mental Health Burden Rising
Researchers discovered that mental disorders ranked as the fifth leading cause of disability-adjusted life years in 2023. In 1990, mental disorders ranked 12th globally. Scientists used disability-adjusted life years, also called DALYs, to measure the number of healthy years lost because of illness. The study examined 12 conditions, including depression, anxiety, schizophrenia, bipolar disorder, autism, eating disorders, and attention deficit hyperactivity disorder. Experts said improved awareness and better reporting may also have increased diagnosis rates worldwide in recent years.
Young People Most Affected
The study showed that teenagers aged 15 to 19 faced the highest mental health burden worldwide. Women also recorded higher rates of mental disorders than men across several regions. Researchers warned that untreated mental health conditions can affect education, employment, relationships, and physical wellbeing. They stressed the importance of early support and affordable treatment. Health experts also encouraged schools and communities to create safe and supportive environments for young people facing emotional or psychological challenges every day.
Experts Urge Better Support
Researchers linked the increase in mental disorders to several global challenges. Child maltreatment, domestic violence, economic inequality, climate change, pandemics, and armed conflict were among the main causes identified in the report. Experts believe governments should invest more in mental healthcare services and awareness campaigns. They also called for stronger healthcare systems to meet growing mental health needs worldwide. Researchers said early intervention, public education, and social support could reduce long-term risks and improve quality of life for millions globally.
