Medical Diagnostics

Background:

Current depression diagnosis relies on subjective methods, lacking objectivity.
Electroencephalography (EEG) offers a non-invasive, cost-effective alternative for objective depression assessment.
Existing EEG analysis faces challenges like volume conduction and class imbalance, hindering diagnostic accuracy.

Purpose of the Study:

To develop an advanced deep learning model for accurate, objective depression classification using EEG signals.
To overcome limitations of current EEG analysis, including volume conduction effects and class imbalance.
To improve the reliability and performance of EEG-based depression diagnosis.

Main Methods:

Proposed a multi-stage deep learning model integrating cortical feature extraction (CFE), feature attention (FA), graph convolutional network (GCN), and focal adversarial domain adaptation (FADA).
CFE utilized standardized low-resolution brain electromagnetic tomography (sLORETA) for cortical signal reconstruction and feature extraction.
FA employed multi-head self-attention for enhanced spatiotemporal feature representation, while GCN modeled functional connectivity.
FADA used Focal Loss and Gradient Reversal Layer (GRL) to mitigate domain shift and class imbalance.

Main Results:

The proposed model achieved a classification accuracy of 85.33% on the PRED+CT dataset.
Demonstrated a significant improvement of 2.16% over existing state-of-the-art methods.
Effectively addressed volume conduction effects and class imbalance issues inherent in EEG data.

Conclusions:

The developed multi-stage deep learning model shows significant promise for objective depression diagnosis via EEG.
The integration of CFE, FA, GCN, and FADA effectively enhances EEG-based depression classification performance.
This approach offers a more accurate and reliable method for identifying depression compared to current techniques.
