Abstract Background: Anhedonia, a prominent symptom of major depressive disorder (MDD), severely impairs patients' quality of life and is challenging to treat. Although esketamine has shown potential in treating anhedonia in adult treatment-resistant MDD, its effects on adolescents remain under-explored. Methods: In this study, a prospective, randomized, double-blind, controlled trial was...
Objective: While inflammatory dysregulation is well-documented in major depressive disorder (MDD), its response to esketamine treatment in adolescents remains poorly understood. We aimed to examine the effects of esketamine on the inflammatory cytokines in adolescent MDD. Methods: This randomized, double-blind trial assigned 49 adolescents with MDD to receive three infusions of esketamine or...
Objective: To investigate neurobiological mechanisms through which esketamine produces rapid antidepressant effects in adolescents with major depressive disorder (MDD), focusing on structural changes in the rostral anterior cingulate cortex (rACC) and associated molecular pathways. Method: A total of 49 adolescents (13-18 years of age) with DSM-5 MDD were randomized to receive intravenous...
