The recognition and optimal management of early psychosis in adolescence is of great importance not only for its adequate diagnosis and treatment, but also for suicide prevention. In this volume, the latest understandings are reviewed by specialists in child and adolescent psychiatry. It discusses questions such as why schizophrenic psychosis has to be differentiated from borderline personality disorders; why the problem-solving strategy in early detection of neurocognitive disorders and neuropsychiatric behavioural disorders is also relevant for the development of a clinical view of the psychotic process. Further contributions point out the choice of specific individual psychotherapeutic techniques as well as why childhood psychosis needs a full inclusion of the family in the diagnostic and therapeutic process. This publication gives a stimulating overview of the diagnosis, treatment and outcome of psychotic disturbances in adolescence.
