Title

Glutamatergic hypofunction in medication-free major depression: secondary effects of affective diagnosis and relationship to peripheral glutaminase

Overall design

In this study, the authors measured levels of glutamate in the dorsal anterior cingulate cortex in-vivo using 1H-Magnetic Resonance Spectroscopy in medication free unipolar and bipolar patients (n=29, 20 unipolar and 9 bipolar) experiencing a major depressive episode, in comparison with a group of matched healthy controls (n=20). The authors also analysed peripheral glutaminase measured in serum to examine the relationship between central and peripheral measures. Metabolite quantification was reported relative to total creatine as the reference peak.
