Abstract

Mental health conditions such as Major Depressive Disorder (MDD) undoubtedly pose severe life-threatening effects if not properly diagnosed and treated promptly. In this paper, we aim to differentiate depressed patients from healthy controls by determining the level of co-functionality relationships between brain regions using the Multi-modal Open Dataset for Mental Disorder Analysis (MODMA) 128-channel resting-state Electroencephalography (EEG) data. By proposing a method that adopts the combination of Phase Locking Value (PLV) functional connectivity analysis with a Contrastive Siamese Network model, we extract PLV-based features and employ the proposed Contrastive Siamese Network to learn discriminative features from the PLV matrices. Our proposed approach achieved an accuracy of 0.88, surpassing prior research works on the same dataset. The results suggest that PLV can serve as a reliable biomarker for depression detection, effectively distinguishing between both classes and leading to robust classification outcomes.
