What was done
The authors conducted a narrative literature review evaluating the use of electroencephalographic (EEG) coherence analysis in depressive disorders. The review focused on EEG coherence as an objective diagnostic biomarker for depression, its potential to predict therapeutic response to different antidepressants, and methodological issues including statistical classifiers and coupling coherence with other EEG analysis methods.
What was found
No numerical data, effect sizes, statistical values, or study counts are reported in the abstract. The abstract notes that the most consistent finding reported across the literature is a decrease in frontal interhemispheric EEG coherence in depressive disorders, alongside potential utility for predicting response to different antidepressants.
Why it matters
Objective neurophysiological markers could assist in diagnosing depressive disorders and tailoring antidepressant selection in clinical practice.
Limits
This is a narrative review that provides no quantitative data, search strategy, inclusion criteria, or study counts in the abstract. Specific patient populations, diagnostic subcategories, and antidepressant types are not described.
