Early intervention for people with psychotic disorders

Abstract Early intervention in psychosis has established itself as a cornerstone of service provision in psychosis over the last two decades. It is the latest in a line of key developments in the management of psychotic disorders over the last 60 years, following the introduction of antipsychotic medication, de-institutionalization, community care, and more effective psychosocial interventions. It borrows from principles that have emerged over the last few decades in other areas of medicine, social care, and education. Its focus is on early detection, prevention, and intervention in young people with emerging first-episode psychosis. It has become a social movement in its own right, developing its own national and international associations (e.g. the International Early Psychosis Association) World Health Organization-endorsed principles, and attracting considerable political, media, and community support. This explosion of interest in early intervention over the past two decades has prompted governments in many developed countries to adopt the early intervention model, with some promoting it as a top priority for mental health service planning. Countries such as UK, Canada, Australia, and New Zealand have committed to national roll-outs of these services. This has been further supported by recent economic evaluations highlighting the substantial health savings involved. The field is now moving into other forms of serious mental illness, not only in conditions typically affecting young people but even into old age psychiatry. However, questions remain regarding the long-term benefits of a focus on early intervention and there is much to discover about the true extent of its merits. There is still uncertainty about the ideal model. Early intervention services wrestle with the dilemma of whether they are for all age groups or specifically for young people, whether they are extensions of child and adolescent mental health services, or young adult services, or both, whether they are limited to non-affective psychoses or all forms of serious mental illness, and whether they are best provided independently of generic services or embedded as subcomponents of these services.
