Mental disorders may affect half the global population by age 75
A study carried out by scientists from the University of Queensland and Harvard Medical School suggests that one in two individuals will develop a mental health disorder in their lifetime. This conclusion is based on a comprehensive global survey where the team closely analyzed data provided by the World Health Organization (WHO) under the World Mental Health Survey Initiative.

The scientists reviewed documentation on more than 150,000 adults from 29 countries gathered between 2001 and 2022. Their analysis of the prevalence of mental health disorders revealed that at least half the population would likely develop a mental disorder before reaching 75. Their findings have been published in the prestigious Lancet Psychiatry journal.
Most common mental health disorders among men and women
Professor John McGrath, the lead author of the analysis from the Queensland Brain Institute UQ, explained that the risk of certain mental illnesses varies based on gender. His team identified the most common mental health disorders affecting both men and women.
The analysis highlighted that depression and specific phobias, which interfere with daily functioning, are the most common afflictions across genders. Women are also significantly more likely to suffer from post-traumatic stress disorder (PTSD), while men generally struggle more frequently with alcohol addiction.
Mental health disorders commonly onset in youth
The scientists noted that mental health disorders often first develop in younger individuals. These issues generally surface during childhood, adolescence, or early adulthood.
The research showed that the peak age for the first onset of mental illness often falls around 15 years. The median onset age was 19 for men and 20 for women.
The authors of the analysis believe that their findings could help shape public health interventions and allocate resources more effectively, offering timely support to those most at risk, including during crucial phases of life.
