82.6% region-level anatomical classification accuracy (+33.1% over VLM baselines)
Implicationpartial
Explicitly stated in the abstract with specific numeric comparison to baselines.
Verificationpartial

Evidencepartial
Zero-shot transfer yields 95.4% on MIRIAD (100% Dementia recall) and 82.9% three-class accuracy on AIBL, confirming high generalizability across sites, scanners, and populations.
Implicationpartial
Directly stated in the abstract with specific numeric results across different datasets.
Verificationpartial
partial
Evidencepartial
The stepped pipeline grounds the final diagnosis by enforcing label consistency, longitudinal coherence, and biological plausibility, thereby reducing the risks of hallucinations.
Implicationpartial
Directly stated in the abstract as a key feature of the method, though specific quantitative evidence of hallucination reduction is not provided.
Verificationpartial
partial
Evidencepartial
The training process introduces a clinically-weighted Verifier that scores candidate outputs automatically against normative references derived from standardized volume metrics, driving Direct Preference Optimization without a single human annotation.
Implicationpartial
Explicitly stated in the abstract as a key methodological innovation.
Verificationpartial
partial
Evidencepartial
This approach might require extensive computational resources for training and might initially face skepticism from clinicians due to reliance on automated systems for diagnosis.
Implicationpartial
Explicitly stated in the analysis section as caveats, though not quantified.
Verificationpartial
partial
Evidencepartial
finally outputs a three-class diagnosis (Cognitively Normal, Mild Cognitive Impairment, or Dementia) along with a synthesized diagnostic summary
Implicationpartial
Directly stated in the abstract as a core function of the system.
