Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Background:

Adolescent depression is a growing concern with significant life impacts.
Current diagnostic methods are time-consuming and lack objective biomarkers.
Early detection is crucial for effective intervention and treatment.

Purpose of the Study:

To develop and validate a novel approach for detecting depression in adolescents.
To leverage affective brain-computer interface (aBCI) and resting-state electroencephalogram (EEG) for enhanced detection.
To explore multimodal fusion of EEG features for comprehensive depression-related information.

Main Methods:

Utilized an affective brain-computer interface (aBCI) combined with resting-state electroencephalogram (EEG).
Fused EEG features from emotional and resting states for comprehensive data capture.
Employed decision fusion of multiple independent models for enhanced detection efficacy.
Conducted experiments with 40 adolescents diagnosed with depression and 40 matched controls.

Main Results:

The proposed model achieved 86.54% accuracy during cross-validation.
The model demonstrated 88.20% accuracy on an independent test set.
Multimodal fusion proved effective in enhancing depression detection.
Distinct brain activity patterns were identified between depressed adolescents and controls.

Conclusions:

The developed aBCI-EEG model shows significant potential for accurate adolescent depression detection.
Multimodal fusion of brain signals offers a promising avenue for objective biomarker development.
Findings suggest new directions for depression screening and therapeutic interventions in adolescents.
