Background:

Depression is a global health issue with diagnostic limitations.
Current diagnostic methods lack objectivity and accuracy.
Resting-state electroencephalography (EEG) offers insights into brain function differences.

Purpose of the Study:

To develop a more accurate and objective method for depression detection.
To utilize resting-state EEG data for identifying depression.
To propose and validate a novel deep learning model for depression recognition.

Main Methods:

Collected resting-state EEG data from 27 depression patients and 28 healthy controls.
Constructed brain functional networks using correlation analysis.
Applied a Graph Convolutional Neural Network (GCN) with a learnable input layer (GICN) using network adjacency and linear EEG features.

Main Results:

The GICN model achieved 96.50% accuracy in distinguishing depression from controls via 10-fold cross-validation.
The proposed GICN model outperformed existing methods.
Analysis identified the temporal lobe and parietal-occipital lobe as crucial for depression identification.

Conclusions:

The GICN model demonstrates potential as an effective auxiliary tool for objective depression diagnosis.
The study highlights the role of specific brain regions in depression.
This AI-driven approach offers a promising advancement in mental health diagnostics.
