Neurodevelopmental understandings
Differential maturation of brain regions with delayed maturation of the prefrontal cortex
Risk-taking, reward-seeking and impulsive behaviours are normative and evolutionary
Interaction with rapidly changing environments for adolescents

Barriers to promoting adolescent mental health
• Highly biomedical model which is out of step with these neurodevelopmental understandings
• Low levels of help-seeking
• Very poor mental health resources: 1 out of 10 of all mental health resources (beds, professionals, dollars) are allocated to countries housing about 9 out of 10 of the global population
• WHO study in 13 low, 24 lower-middle, and 5 upper-middle-income countries (Morris et al, J Child Psychol Psychiatr 2011)– Children and adolescents make up 12% of the patient population in mental
health outpatient facilities and less than 6% in all other types of mental health facilities.
– Less than 1% of beds in inpatient facilities are reserved for children and adolescents.
– Training provided for mental health professionals on child and adolescent mental health is minimal

The action needed

Principles
• Focus on high burden conditions • Cost-effective interventions for prevention and
care which are consistent with neurodevelopmental findings
• Integrated with established platforms, e.g. youth friendly services, schools
• Delivery by non-specialized workers, including peers, lay counsellors and community health workers

Examples of actions
• The early detection and management of mental disorders
• Preventive strategies to train children and youth to improve cognitive control and manage stress to reduce the propensity for “hot cognition.”
• Limiting access to harmful risk-taking situations and providing opportunities to engage are less harmful, but equally rewarding

Priority actions
Top 5 challenges ranked by disease-burden reduction, impact on equity, immediacy of impact and feasibility.
Challenge
1Integrate screening and core packages of services into routine primary health care
2Reduce the cost and improve the supply of effective medications
3
Improve children’s access to evidence-based care by trained health providers in low- and middle-income countries
4Provide effective and affordable community-based care and rehabilitation
5
Strengthen the mental-health component in the training of all health-care personnel

The impact
New resources: e.g. Grand Challenges Canada (C$50m in 2012/3 in two programs: Saving Brains and Global Mental Health)
Over 50 institutions around the world engaged in research to address the GCGMH in past 24 months

Other research priorities
Examining how shared genetic predispositions and neurodevelopmental trajectories interact with environmental factors to lead to differential phenotypes of dysphoria and risk behaviors in youth.
Large population-based cohorts of young children with explicit interdisciplinary leadership, in diverse sociocultural contexts.

Summary
The proportionate burden of mental disorders in childhood rises with age, reaching 15 to 30% in adolescence
The interaction of the features of neurodevelopment in adolescence and rapidly changing environments predispose to a range of risk behaviours and mental illness
Highly biomedical approaches relying on scarce resources, combined to low levels of help-seeking and very low levels of research from developing countries mean that probably <5% of the mental health care needs of adolescents are addressed
Developmentally appropriate interventions integrated with youth friendly services and promoting global research are key strategies for the future
