Title | Early increase in marker of neuronal integrity with antidepressant treatment of major depression: 1H-magnetic resonance spectroscopy of N-acetyl-aspartate |
Overall design | This study used magnetic resonance spectroscopy to assess effects of short-term treatment with escitalopram on N-acetyl-aspartate (NAA), a marker of neuronal integrity. Thirty-nine participants with major depression were randomly assigned to receive either 10 mg escitalopram (escitalopram group, n = 19) or placebo (placebo group, n = 21) daily in a double-blind, parallel group design. On the seventh day of treatment, PRESS data were obtained from a 30x30x20 mm voxel placed in medial frontal cortex. Age and gender-matched healthy controls (control group, n = 27) who received no treatment were also scanned. Metabolite quantification was reported relative to total creatine as the reference peak. |
