Abstract

Objectives

Growing attention has been directed toward the structural and functional alterations among individuals infected with COVID-19. However, data on its impact on patients with Major Depressive Disorder (MDD) remain limited.

Methods

This study investigates the effects of COVID-19 on patients with MDD and healthy controls (HCs) using MRI scans. Participants were categorized into four groups: MDD patients before (n = 165) and after COVID-19 infection (n = 70), HCs before (n = 108) and after COVID-19 infection (n = 57). All participants underwent T1-weighted imaging, diffusion tensor imaging (DTI), and resting-state functional MRI from January 2022 to August 2023.

Results

Structural alterations associated with COVID-19 were predominantly observed in the white matter (WM) rather than the gray matter (GM), with specific involvement noted in the superior longitudinal fasciculus tract, Forceps minor tract, and cingulum-cingulate gyrus tract among patients with MDD. Functional changes were spread from GM to WM. The bilateral supplementary motor area, the left angular gyrus, the left subcortical regions (amygdala and parahippocampal gyrus), and various WM tracts showed significant infection-related changes across groups.

Conclusion

COVID-19 infection induces significant microstructural damage of WM in healthy individuals and exacerbates white matter microstructural injury of MDD. These findings suggest that WM might be more susceptible to COVID-19 effects than GM in both MDD patients and HCs.

期刊介绍： Founded in 1961 to report on the latest work in psychiatry and cognate disciplines, the Journal of Psychiatric Research is dedicated to innovative and timely studies of four important areas of research: (1) clinical studies of all disciplines relating to psychiatric illness, as well as normal human behaviour, including biochemical, physiological, genetic, environmental, social, psychological and epidemiological factors; (2) basic studies pertaining to psychiatry in such fields as neuropsychopharmacology, neuroendocrinology, electrophysiology, genetics, experimental psychology and epidemiology; (3) the growing application of clinical laboratory techniques in psychiatry, including imagery and spectroscopy of the brain, molecular biology and computer sciences;
