Early Detection and Intervention in Psychosis

As this volume shows, early detection of and intervention in psychosis is a rapidly evolving and highly promising field of psychiatry. Starting with the early detection of frank psychosis and building up services for this, the field has in the meantime developed. By now, there is clear and accumulating evidence that early detection is also possible before transition to frank psychosis in the early prodromal and subthreshold psychotic states, i.e. in the sense of risk-assessment. Moreover, there is a large body of evidence regarding early intervention. However, it is also clear that there are still some unsolved problems and questions and a lot has still to be done.
