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. The WHO Department of Mental Health and Substance Use 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 as well as people with addictive behaviours and substance use disorders.
