    Cogninet is a deep learning framework designed for four-way classification of cognitive stages: CN, MCI, pMCI, and AD using MRI data.

  • 2

    The model incorporates Grad-CAM visualizations to enhance interpretability and support clinician trust in automated diagnostic systems.

  • 3

    Cogninet outperforms baseline CNN models in diagnostic accuracy, sensitivity, and precision across all cognitive stages.

  • 4

    The study addresses the need for fine-grained classification in Alzheimer's diagnosis and integrates explainable AI tools for usability.

  • 5

    MRI data for the study was sourced from the ADNI database, focusing on axial slices relevant for identifying anatomical changes in AD.
