United Nations and World Health Organisation Engagement in TreatingGlobal Mental Health, with a Special Focus on Dementia

A sharp attention is devoted to mental health and mental illness by International Law and many International Organizations (IO’s) in XXI century. As a consequence of human rights huge extension, mental health is nowadays a target of international efforts striving to address both States national choices and international achievements. World Health Organization (WHO) is expressly engaged, but United Nations (UN) opened up the legal path in early nineties, by UN General Assembly (UNGA) 46/119 of 17 December 1991, The protection of persons with mental illness and the improvement of mental health care, where mental health care and facilities are pointed out; and if mental illness couldn’t be defined, Principle 4 (Determination of mental illness) of this Resolution is crucial to direct next improvements layout. From there, UN and WHO have been carrying on a unique approach to mental health, as proved by binding and non-binding international acts, surveys, guidelines – as the 2010 WHO mhGAP Intervention Guide, now updated in its 2016 version – adopted as a result of States consultation. UNGA Resolution 70/1 of 21 October 2015, Transforming Our World: the 2030 Agenda for Sustainable Development, envisaging 17 Sustainable Development Goals (and replacing past 8 Millennium Development Goals to be gained in 2015 at last) is the last step on the road of a global approach to health, both physical and mental in an holistic view of human beings. As stated in Declaration’s Introduction, “no one will be left behind”. This article aims to investigate mental health as an international legal issue on a broad sense, not only compared to lack of mental illness, but in a comprehensive view dealing with it by implementing International Law on Human Rights. Dementia prevention and care above other mental diseases is perceived in a global framework of domestic economic and social balance (2012 WHO Dementia, a Public Health Priority), even though national health care systems still depend upon national policies in investments assets. But States’ attitude to healthcare services in mental health should now be oriented by International Law current evolution.
