Multimodal AI Improves Alzheimer Disease Diagnosis Performance
A systematic review published in J Med Internet Res (final search Nov 15, 2025) analyzed 66 studies from 2019–2025 on multimodal AI for Alzheimer disease diagnosis, prognosis, and risk prediction, finding multimodal models consistently outperformed single-modal baselines. Across datasets, ADNI diagnosis averaged 92.5% accuracy, MCI-conversion models averaged AUC 0.922, UK Biobank risk models averaged AUC 0.84, and authors call for standardized benchmarks, transparent evaluation, and clinically grounded designs due to heterogeneity and bias limiting generalizability.
Key Points
- 1Demonstrates multimodal models outperform single-modality baselines across 66 studies and multiple dataset families
- 2Highlights substantial performance on ADNI (92.5% accuracy) and MCI conversion (AUC 0.922) indicating clinical potential
- 3Warns of heterogeneity, bias, and small self-collected cohorts, urging standardized benchmarks and transparent evaluation
Scoring Rationale
Comprehensive, registered systematic review synthesizes robust dataset comparisons; limited by heterogeneity and variable external validation.
