Title | Left DLPFC activity is associated with plasma kynurenine levels and can predict treatment response to escitalopram in major depressive disorder |
Overall design | The aim of this study was to determine the relationship between regional brain activity at rest and blood metabolites related to treatment response to escitalopram to identify the characteristics of depression that respond to treatment. Blood metabolite levels and resting-state brain activity were measured in patients with moderate to severe depression (depression group, n = 65) before and after 6-8 weeks of treatment with escitalopram, and these were compared between responders (>50% reduction in the HRSD score; responder group, n = 32) and nonresponders (nonresponder group, n = 33) to treatment. The relationship between plasma metabolites and brain activity related to treatment responsiveness were examined in patients and healthy controls (control group, n = 36). |
