A recent international study has revealed that the number of people suffering from mental disorders worldwide has nearly doubled since 1990, reaching approximately 1.2 billion. These findings, published in the journal The Lancet, indicate that mental disorders have become the leading cause of disability globally, surpassing heart diseases and cancer.
The study was conducted by the Institute for Health Metrics and Evaluation at the University of Washington in collaboration with the University of Queensland in Australia. It involved a comprehensive analysis of the prevalence and impact of mental disorders across genders, covering 25 age groups, 21 regions, and 204 countries and territories, making it one of the most extensive studies in this field.
Event Details
The researchers focused on 12 types of mental disorders, with anxiety and severe depression being among the top contributors to the burden of disease and disability across 304 diseases and injuries worldwide. The results showed that the mental health burden is higher in certain high-income regions, such as Western Europe and Australia, with elevated rates recorded in countries like the Netherlands and Portugal.
Additionally, regions in West Africa and South Asia have seen significant increases in the rates of mental disorders. According to the study, these disorders resulted in the loss of approximately 171 million years of potential life lost due to disability or premature death in 2023, making them the fifth leading cause of disease burden globally.
Background & Context
The recent rise in mental disorder rates is largely attributed to increasing levels of anxiety and severe depression, with the prevalence of depression rising by 24% since 2019, while anxiety disorders have increased by over 47%, particularly following the COVID-19 pandemic. Researchers confirmed that the burden of these disorders peaks among individuals aged 15 to 19, as well as among women.
Stressors related to the pandemic, alongside structural factors such as poverty and violence, exacerbate these conditions. The results also showed variations in the patterns of disorders by age group, with conditions like autism and attention deficit hyperactivity disorder being more prominent in childhood, while anxiety and severe depression become more prevalent during adolescence.
Impact & Consequences
The impact of mental disorders extends beyond individuals, affecting families, caregivers, the labor market, and health systems. The study estimated that only about 9% of individuals with severe depression receive the minimum appropriate care, while the percentage receiving adequate treatment falls below 5% in 90 countries.
Data indicates that a limited number of high-income countries, such as Australia and Canada, have treatment coverage exceeding 30%, revealing significant gaps in mental health services worldwide. Therefore, expanding access to mental health services, especially in low- and middle-income countries, is an urgent necessity to mitigate the worsening of this crisis.
Regional Significance
In the Arab region, specific challenges related to mental disorders emerge, as many countries suffer from a lack of mental health services. Political, economic, and social crises contribute to the exacerbation of these disorders, necessitating effective responses from governments and communities to improve the quality of mental healthcare.
In conclusion, this study underscores the need for intensified global and local efforts to address the mental health crisis and provide necessary support to affected individuals, reflecting the importance of community awareness and government support in improving people's mental well-being.
