Mental health issues among indigenous communities and the role of traditional medicine.

INTRODUCTION

Mental health in indigenous communities is a relevant issue for the World Health Organization (WHO). These communities are supposed to live in a pure, clean and intact environment. Their real condition is far different from the imaginary; they are vulnerable populations living in difficult areas, exposed to pollution, located far from the health services, exposed to several market operations conducted to extract natural resources, facing criminal groups or illegal exploitation of land resources. These factors may have an impact on mental health of indigenous population.

METHODS

We reviewed all papers available on PubMed, EMBASE and The Cochrane Library until December 2018. We focused on those factors affecting the changes from a traditional to a post-modern society and reviewed data available on stress-related issues, mental distress affecting indigenous/aboriginal communities and the role of Traditional Medicine (TM). We reviewed articles from different countries hosting indigenous communities.

RESULTS

The incidence of mental distress and related phenomena (e.g. collective suicide, alcoholism and violence) among indigenous populations is affected by political and socio-economic variables. The mental health of these populations is poorly studied and described even if mental illness indicators are somewhat alarming. TM still seems to have a role in supporting affected people and may reduce deficiencies due to poor access to medical insurance/coverage, psychiatry and psychotherapy. It would be helpful to combine TM and modern medicine in a healthcare model to face indigenous populations' health needs.

CONCLUSION

This review confirms the impact of societal changes, environmental threats and exploitation of natural resources on the mental health of indigenous populations. Global Mental Health needs to deal with the health needs of indigenous populations as well as psychiatry needs to develop new categories to describe psychopathology related to social variance as recently proposed by the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5).
