Mental Disorder Cases Nearly Double Since 1990, Study Finds
Anxiety and depression drove the increase, and women and 15- to 19-year-olds were hit hardest, researchers said.
Nearly 1.2 billion people worldwide lived with mental health disorders in 2023, according to a new study published in The Lancet on Thursday, reflecting a 95.5% increase since 1990.
Mental health disorders now disproportionately affect younger populations, with researchers identifying a peak in the 15- to 19-year-old age group for the first time; Dr. Damian Santomauro, the study's lead author, said he "was honestly shocked at the magnitude."
Researchers observed an 158% rise in anxiety and a 131% uptick in depression compared to 1990 levels across 204 countries, with roughly one in eight people globally currently living with a mental health condition.
Despite the crisis, median government spending on mental health remains just two percent of health budgets globally, and the study's authors warned this increased burden lacks proportional expansion of mental health services.
Experts advise individuals to prioritize lifestyle factors such as sleep and social connection while seeking professional help, emphasizing that addressing these rising health risks requires global collective leadership.
According to one study, the number of mentally ill people has almost doubled over the past 30 years. Women and adolescents are particularly affected, two diagnoses stand out.
