This thesis deals with the clinical picture of schizophrenia during the age of adolescence where the focus is laid on the individual aspects and characteristics, as well as the early stages, of the disease. It puts an especial emphasis on the impacts on young people and the diverse forms of process to subsequently showcase the functions social work takes over when in contact with said schizophrenic youth. Therefore, the diagnostic criteria ICD-10 as well as the latest DSM-5 will be used as an initial point for the further work on the topic. Additionally, potential reasons and parameters, which could influence the process of the disease, will be defined, whereas the relation between schizophrenia and the consumption of cannabis will be described too. In addition, there will be an analysis of the especial impacts of the disease on adolescents. Then the diverse forms of process will be put forward, where the prodromalphase will be included particularly. This leads to an explanation about the relevance of the prodromal symptoms and the potential early interventions. This finally concludes in combining the topic with the field of social work, where the benefits of knowledge on juvenile schizophrenia will be explored within different contexts.
