Etiology and Treatment of Psychotic Disorders

Description of Research:

The aims of the project are basically two-fold:

  1. to test a wide set of etiological hypotheses of psychotic disorders using a dimensional clinical concept of psychosis. We use an extensive clinical methodology battery combined with brain structural and functional imaging (PET, sMRI, fMRI) as well as metabolomics (lipidomics), genetics and immunological approaches (e.g. CNS microglia studies)
  2. We use this multimodal biomarker database together with bioinformatics, statistical modelling, artificial intelligence techniques and neural networks to provide leads to predict illness course, outcome, treatment responses (follow-up of patients) and to develop novel treatments for early psychosis.
