Unmasking Latent Cognitive Risk: The Synergy of MMSE and Structural Brain Atrophy
Traditional cognitive assessments, like the MMSE, often miss early signs of neurodegeneration due to their inherent 'ceiling effect'. This study pioneers an explainable deep learning framework that integrates MMSE scores with Normalized Whole Brain Volume (nWBV) to detect subtle, yet critical, structural brain changes, revealing hidden cognitive impairment risks in individuals who appear 'normal' on standard tests.
This research addresses a critical gap in early cognitive impairment detection, offering a more precise and comprehensive approach to risk screening.

The Challenge: MMSE's Blind Spots
The Mini-Mental State Examination (MMSE), while widely used, suffers from a 'ceiling effect' at higher scores, making it insensitive to early or subtle cognitive decline. This can lead to a significant portion of the population with preclinical neurodegenerative changes being misclassified as cognitively normal.
Our AI-Powered Solution: Integrating Structural Biomarkers
We introduce an explainable deep learning framework that combines MMSE scores with Normalized Whole Brain Volume (nWBV) – a robust indicator of structural brain atrophy. This integration reveals latent cognitive impairment risks even in individuals with normal MMSE scores.
Transformative Impact: Precision Risk Screening
This approach enables earlier, more precise identification of individuals at risk of cognitive decline, facilitating proactive interventions and personalized care strategies. Our findings, validated with explainable AI (XAI) techniques, demonstrate a consistent and reliable method for enhancing clinical decision support.

MMSE Scores Often Mask Latent Cognitive Decline
Even individuals scoring in the normal range on the Mini-Mental State Examination (MMSE) can harbor underlying neurodegenerative changes. The MMSE's ceiling effect limits its sensitivity to early or subtle impairment, leading to misclassification of at-risk individuals as cognitively intact.

OVR-AUC
Across four distinct deep learning architectures (MLP, TabResNet, Tab Transformer, FT Transformer), classification performance remained consistently high and showed no statistically significant differences. This confirms that the predictive power is driven by the rich informational content of the input variables (MMSE and nWBV), rather than the specific model complexity.

Increased Latent Risk for MMSE-Normal Individuals with nWBV Decline
In the MMSE-normal subgroup, a decrease in nWBV (normalized whole brain volume) was strongly associated with a 1.65-fold increased risk of mild cognitive impairment or dementia (CDR ≥ 0.5), even after adjusting for age and sex. This highlights nWBV's ability to reveal preclinical vulnerabilities.
Case Study: Identifying Hidden Risk in a "Normal" Patient
A 65-year-old executive consistently scores 29 on the MMSE, indicating 'normal' cognitive function. However, an integrated AI assessment reveals a lower-than-average nWBV for their age group. Our framework, leveraging explainable AI, identifies this structural anomaly as a significant risk factor, predicting a higher probability of developing cognitive impairment within the next 5 years. This early insight enables proactive lifestyle interventions and targeted monitoring, far sooner than traditional MMSE-only screening would allow.
