‘The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers. You would agree with me? Yes.’
(Attributed to Socrates, probably from Plato's Republic, book 4)
This famous (possibly apocryphal) quotation tells us how adults have always found it difficult to understand the young, even though they have themselves not long since been members of the breed. Adolescence is a turbulent period of flux with a complex interplay between biological, psychological and social changes as young people navigate their way to adulthood, embark on career pathways, assume adult roles and responsibilities and develop sexual relationships. Parent–child conflict can develop and intensify as adolescents struggle for independence while still requiring support. In this supplement we learn of the paradox that although adolescence and early adulthood are a period of maximum physical health, Reference McGorry1 it is a period with a steep rise in mental health problems. Reference Jones2 Prospective studies suggest that more than half of young people by the age of 21 years will have experienced one or more psychiatric disorders, Reference Costello, Angold, Burns, Stangl, Tweed and Erkanli3,Reference Silva4 with many starting in childhood. Although society is concerned with the healthcare needs of an ageing population, we also have overwhelming evidence that the foundation of lifelong mental health begins in childhood, particularly in adolescence – a time when emerging mental health problems are underrecognised and certainly undertreated. Reference McGorry1 Recent large epidemiological studies have demonstrated that over three-quarters of serious mental health problems begin before the age of 25 years, with those that start later being delayed presentations or secondary conditions. Reference Jones2,Reference Kessler, Chiu, Demler, Merikangas and Walters5
In this supplement Lin et al and McGorry argue that many of these adolescent disorders are rather undifferentiated, poly-symptomatic presentations that are capable of progressing to more traditional differentiated types with the passage of time and ongoing biosocial process; Reference McGorry1,Reference Lin, Reniers and Wood6 they call it the ‘staging’ model, taken from staging familiar in oncology. Lin et al outline the concept and the supporting evidence, Reference Lin, Reniers and Wood6 and argue that this provides a framework for the study of developmental psychopathology and – crucially – for prevention and public health, currently high on the UK policy agenda. 7
Current evidence strongly suggests that mental health problems presenting in adolescence increase the risk of disorder occurring in adulthood, Reference Jones2 hence providing a conceptual basis for early intervention, including a focus on high-risk groups. Stallard & Buck and Chanen & McCutcheon present two examples: Stallard & Buck describe a successful pilot investigation to prevent depression in adolescents through a school-based intervention focusing on those at risk, Reference Stallard and Buck8 and Chanen & McCutcheon report on an early intervention approach for emerging borderline personality disorder in adolescents. Reference Chanen and McCutcheon9 This work builds on existing work developing early intervention in relation to eating disorders and the psychoses. Reference McGorry1
Matching service to need
How best should we provide mental health support to our young people? For many years the international care model has distinguished the child and adolescent mental health service (CAMHS) pathway for those aged up to 18 years (or 16 years in some settings) from adult mental health services (AMHS). The developmental dimension described above broadly supports such a distinction, particularly if opportunities for prevention are realised. Singh et al, however, reported that the transition from CAMHS to AMHS is problematic for many adolescents, with a large proportion dropping through a care gap between the two services and losing much-needed continuity of care. Reference Singh, Paul, Ford, Kramer, Weaver and McLaren10 Adolescents with a serious mental illness such as psychosis or bipolar affective disorder under CAMHS care do get referred to adult care, especially if in receipt of medication or admitted to hospital. However, young people with conditions such as attention-deficit hyperactivity disorder (ADHD), autism spectrum disorders, mild intellectual disability, emotional and neurotic disorders and emerging personality disorder are either not referred to adult care or if referred are not accepted. Those who do make the journey across services feel unprepared for the transition and the abrupt cultural shift from a child-centred developmental approach to the adult care model. It is perhaps for this reason that many disengage from adult services. For the majority, transition is poorly planned, poorly executed and poorly experienced. Singh et al reported that many felt overburdened and others felt abandoned by services. Reference Singh, Paul, Ford, Kramer, Weaver and McLaren10,Reference Paul, Ford, Kramer, Islam, Harley and Singh11 Clearly this lamentable state of affairs needs to be corrected.
The question then arises whether the problems with the CAMHS–AMHS distinction at age 16 or 18 years can be remedied, or whether we should consider it as fundamentally flawed and a structural impediment to care and treatment. Jones describes a steep rise in age incidence at this time, Reference Jones2 and McGorry et al argue therefore that ‘the current system is weakest where it needs to be strongest’. Reference McGorry1 McGorry et al challenge us to consider whether, if we were to design services now, we would propose the present structure or argue instead that a care pathway from age 12 years to 25 years best fits epidemiological data and clinical need. Reference McGorry, Bates and Birchwood12 According to McGorry et al this would fit with international definitions of youth, and incidentally in the UK would align with local authority definitions. Reference McGorry, Bates and Birchwood12
Lamb & Murphy present a considered analysis of the current position and options from a CAMHS perspective. Reference Lamb and Murphy13 They argue that separate commissioning frameworks for CAMHS and AMHS potentiate discontinuities and are inimical to good care and effective use of resources. They raise critical questions about the future structure of services for young people and consider a number of potential options for service redesign. McGorry et al describe alternative service models from the different settings of Australia, Ireland and England. Reference McGorry, Bates and Birchwood12 Neither the status quo nor these alternative models have clear evidence of efficacy; McGorry et al argue that the issue here is to agree on the criteria that need to be followed in designing such services, for example that they are aligned to evidence on epidemiology and age at onset and meet opportunities for prevention. Reference McGorry, Bates and Birchwood12 These two papers, by Lamb & Murphy and McGorry et al, together lay out the critical issues in reforming mental health services for our young people.

Concluding remarks
In the UK a zeitgeist has emerged in government policy encouraging more systematic attention to public mental health and prevention, 7 one that the Royal College of Psychiatrists has strongly endorsed. 14 A consistent theme of the papers in this supplement is that we can realise this aspiration by a fundamental review and reform of mental health services for young people so as to give them (and us) the best opportunity to prevent lifelong recurrence. We hope that this supplement will trigger a much-needed debate about the future of services for our young people so that, unlike Socrates, we will no longer look upon them as a lost cause.
