Schizotypal personality disorder shares biological, genetic, and clinical features of schizophrenia however little is known the alterations of brain neurochemistry, in particular the important neurotransmitters of GABA and glutamate. Our goal was to use spectral editing and 2D correlated spectroscopy techniques to measure the concentration of these chemicals in SPD subjects. Our results show a decrease in GABA and increase in glutamate in SPD subjects when compared with controls. Results of the different MRS methods were also compared and showed to share the same results however 2D COSY provided additional information beyond the other techniques.
