Discussion

Meta-analysis reveals significant alterations in glutamatergic neurometabolite levels in MDD, suggesting implications for treatment.

Significant decreases in glutamatergic neurometabolites were found in the anterior cingulate cortex and prefrontal cortex of MDD patients.
The analysis included data from 1400 MDD patients and 1322 healthy controls across 55 studies.
Meta-analysis conducted by searching major databases indicated moderate-to-high heterogeneity across studies.
Findings underscore the need for further exploration into the impact of antidepressant treatment on neurometabolite levels.

Tao et al. (2025) studied this question.
