Paper Abstract

Phosphorus-31 magnetic resonance spectroscopy (31P-MRS) has gained much interest in schizophrenia research in the last years since it allows the non-invasive measurement of high- energy phosphates and phospholipids in vivo. We investigated hemispherical differences of the concentrations of different phosphorus compounds in the frontal lobes. For this purpose, well defined volumes in the dorsolateral prefrontal cortex of 32 healthy controls and 51 schizophrenic patients were examined. Schizophrenic patients showed significant lateralization effects of phosphodiesters (PDE) and the intracellular pH-value. Differences in the lateralization of 31P-MRS parameters between patients and healthy volunteers were only detected for the pH-value. While healthy controls exhibit lower pH-values in the left frontal lobe (6.96), in schizophrenic patients we found lower pH-values in the right (6.89). Detailed examinations showed that this effect is mainly based on the subgroup of schizophrenics who received atypical neuroleptic medication.
