    Area of Science:

    • Neuroscience
    • Artificial Intelligence
    • Medical Diagnostics

    Background:

    • Current dynamic functional connectivity (dFC) methods like sliding window correlation (SWC) lack temporal precision, impacting network accuracy.
    • Existing deep learning models may fail to capture crucial disease-related spatio-temporal patterns for conditions like mild cognitive impairment (MCI).

    Purpose of the Study:

    • To develop a novel spatio-temporal attention-based bidirectional gated recurrent unit (STA-BiGRU) network for enhanced MCI identification.
    • To extract more accurate and discriminative spatio-temporal information from dynamic adaptive functional connectivity (dAFC) networks.

    Main Methods:

    • A group lasso-based Kalman filter algorithm was used to generate dAFC networks with precise time-step connectivity.
    • A BiGRU network integrated spatial and temporal attention modules to capture disease-specific patterns.
    • Spatio-temporal regularizations were applied to improve the deep network's robustness.

    Main Results:

    • The proposed STA-BiGRU framework achieved high mean accuracies of 90.2%, 90.0%, and 81.5% on three distinct MCI classification tasks.
    • The method demonstrated superior performance in extracting disease-related spatio-temporal information compared to existing approaches.

    Conclusions:

    • The study presents an effective deep learning framework, STA-BiGRU, for analyzing dAFC networks in MCI diagnosis.
    • The proposed network offers improved accuracy and interpretability for deep learning applications in psychiatric diagnosis.
