RESUMO
BACKGROUND: Schizophrenia is the collective term for an exclusively clinically diagnosed, heterogeneous group of mental disorders with still obscure biological roots. Based on the assumption that valuable information about relevant genetic and environmental disease mechanisms can be obtained by association studies on patient cohorts of ≥ 1000 patients, if performed on detailed clinical datasets and quantifiable biological readouts, we generated a new schizophrenia data base, the GRAS (Göttingen Research Association for Schizophrenia) data collection. GRAS is the necessary ground to study genetic causes of the schizophrenic phenotype in a 'phenotype-based genetic association study' (PGAS). This approach is different from and complementary to the genome-wide association studies (GWAS) on schizophrenia. METHODS: For this purpose, 1085 patients were recruited between 2005 and 2010 by an invariable team of traveling investigators in a cross-sectional field study that comprised 23 German psychiatric hospitals. Additionally, chart records and discharge letters of all patients were collected. RESULTS: The corresponding dataset extracted and presented in form of an overview here, comprises biographic information, disease history, medication including side effects, and results of comprehensive cross-sectional psychopathological, neuropsychological, and neurological examinations. With >3000 data points per schizophrenic subject, this data base of living patients, who are also accessible for follow-up studies, provides a wide-ranging and standardized phenotype characterization of as yet unprecedented detail. CONCLUSIONS: The GRAS data base will serve as prerequisite for PGAS, a novel approach to better understanding 'the schizophrenias' through exploring the contribution of genetic variation to the schizophrenic phenotypes.

Germany, in comparison to other countries, provides a good quality of services to distinct groups of patients. But as far as total expenditure for mental health services is concerned, it belongs to the top European states. The differentiation of services since the Expert Commission to the parliament (1975) was associated by fragmentation of the therapeutic alliances and the patient's relations in his or her personal social system. The management of intake to hospital treatment seems to need further improvement. Treatment paths which integrate distinct sectors are clinically tested in other countries and should be hold up as examples for politicians to further improve our mental health services. With the available resources, better and economically sound results could be reached. This is important for the future, a) because of increasing utilization of mental health treatment, b) to guarantee the quality of services for the chronic, severely mentally ill patients.
