Mental well-being is a fundamental component of WHO's definition of health . Good mental health enables people to realize their potential, cope with the normal stresses of life, work productively, and contribute to their communities. Mental health matters, but the world has a long way to go to achieve it. Many unfortunate trends must be reversed-neglect of mental health services and care, and abuses of human rights and discrimination against people with mental disorders and psychosocial disabilities. This comprehensive action plan recognizes the essential role of mental health in achieving health for all people. It is based on a life-course approach, aims to achieve equity through universal health coverage and stresses the importance of prevention . Four major objectives are set forth: more effective leadership and governance for mental health; the provision of comprehen- sive, integrated mental health and social care services in community-based settings; implementation of strategies for promo- tion and prevention; and strengthened information systems, evidence and research . Although the targets of this action plan are ambitious, WHO and its Member States are committed to fulfilling them . Dr Margaret Chan Director-General World Health Organization.
