Title

Tissue-specific differences in brain phosphodiesters in late-life major depression

Overall design

The aim of this study was to measure individual membrane metabolites in subjects with late-life depression versus normal comparison subjects. Patients with late-life major depression who were medication free at time of study (depression group, n = 10) and aged normal comparison subjects (control group, n = 11) were studied using phosphorus magnetic resonance spectroscopy (31P MRS) three-dimensional chemical shift imaging at 4 Tesla. For each metabolite, the peak area was normalized by the total phosphorous signal.
