Abstract
In today's world, increasing stress and depression significantly impact cognitive well-being, making early detection of cognitive impairment essential for timely intervention. This work introduces a Multimodal Fusion Cognitive Assessment Framework that leverages advanced deep learning and graph intelligence to enhance early identification accuracy. Traditional tools like the Montreal Cognitive Assessment (MOCA) are limited in adaptability, prompting the need for a more dynamic, data-driven approach. The framework is validated using datasets involving cognitive tests, voice samples, and physiological signals. It enables a scalable, personalized, and adaptive cognitive assessment system that improves early detection and supports targeted intervention strategies. By integrating deep learning and information fusion, this approach addresses the complexity of cognitive health in a modern context.•This paper introduces Multimodal Deep Learning Integration, incorporating MOCA scores, behavioral data, speech signals, and physiological parameters using GAT, TAT, and CNN-LSTM models to capture diverse cognitive indicators.•The proposed model achieves superior performance through Information Fusion via Heterogeneous GNNs, effectively merging cross-domain data to enable holistic cognitive state assessment via inter-modality learning.•This paper applies Reinforcement Learning (RL) to personalize user interactions based on real-time cognitive and stress cues, reducing cognitive overload and enhancing engagement.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
