31P-spectroscopy of frontal lobe in schizophrenia: alterations in phospholipid and high-energy phosphate metabolism.

Studies using 31P-magnetic resonance spectroscopy (MRS) reported on abnormalities in frontal lobe metabolism in schizophrenia. The most consistent findings were a reduction in the resonances of phosphomonoesters (PME) and/or increased phosphodiesters (PDE), which are, respectively, the precursors and the metabolites of membrane phospholipids, thus suggesting an accelerated phospholipid metabolism in the disease. Other studies reported increased high-energy phosphates (ATP-adenosine triphosphate and PCr-phosphocreatine) in schizophrenia, reflecting decreased use of energy in the frontal lobe.
