INTRODUCTION: This study investigated changes in multiband amplitude of low-frequency fluctuations in patients with major depressive disorder following a 2-week combination treatment regimen of esketamine and sertraline, and examined the associations between ALFF changes and clinical symptom improvement. METHODS: Forty patients with major depressive disorder (MDD) received esketamine (0.25...
This study aims to explore the relationship between the antidepressant effects of drugs (esketamine combined with sertraline) and brain function changes in patients with major depressive disorder. A total of 27 patients with major depressive disorder (MDD) and 27 healthy individuals were included in the study. All MDD patients received a 2-week course of intravenous esketamine infusion (0.25...
We aimed to investigate the relationship between changes in resting-state functional connectivity in a subregion of the hippocampus and the antidepressant effects of esketamine as well as to identify potential neuroimaging markers of the treatment outcomes. Twenty-nine patients with major depressive disorder (MDD) received six intravenous infusions of esketamine. All patients completed the...
Esketamine has demonstrated acute antidepressant effects in patients with major depressive disorder (MDD). This study investigated whether these effects associate with reversible white matter fiber integrity recovery using diffusion imaging. Twenty patients with MDD and 20 healthy controls received 2-week esketamine treatment. Patients received 0.25 mg/kg intravenous esketamine. Emotional and...
