Brief description This study will investigate the role of fatty acids (lipids) in schizophrenia. Studies in blood cells and in the brains of patients with schizophrenia have shown that these lipids and related products are altered in schizophrenia. We are now able to measure separate lipid metabolites in the living human brain using a technique called magnetic resonance spectroscopy. Until recently it was only possible to assess lipid metabolites as a group, limiting interpretation. Thanks to a newly available imaging system at the Brain Imaging Research Institute and a new analysis technique, we will be able to measure single lipid metabolites in the living human brain. Simultaneously we will also measure lipids and related enzymes in red blood cells that are responsible for the regulation of these lipids. Preliminary data has shown that there is a strong correlation between these two measures. Furthermore we will investigate the genes that are responsible for the production of these enzymes. By repeating the same tests after 12 weeks we hope to understand how the newer antipsychotic drugs act. Two easy clinical tests (a skin and breath test) will help us to implement the findings in daily clinical practice (diagnostic markers for patients at risk) . With such a multi-level approach we hope to contribute to a new understanding of the origins of schizophrenia going beyond the traditional concepts. The findings might also have direct implications for treatment. Preliminary results are very promising but also contradictory. Therefore it is even more important to carefully investigate the role of these lipids in schizophrenia.
