People with mental, neurological and substance use conditions require access to affordable high-quality and evidence-based treatment and care that is consistent with human rights approaches. WHO assists countries to put in place quality care services and support networks through the development of technical standards and guidance.  

These include tools and interventions used across the life course that support: early child development; perinatal mental health; the mental and brain health of children and adolescents; people with mental and brain health conditions, and people with addictive behaviours and substance use disorders.

The WHO Comprehensive mental health action plan, 2013-2030 recommends pre-service education of health professionals on core competencies for mental, neurological and substance use care. WHO published a practical guide for the pre-service education of medical and nursing students.
