Concise Statement: GrimAge-derived epigenetic age acceleration, when deconvoluted for neuronal vs. glial cell-type proportions in CSF-derived cell-free DNA, will outperform single-tissue blood-based clocks in distinguishing early Alzheimer's disease from MCI and healthy aging with >85% sensitivity and specificity.
Mechanistic Rationale:
GrimAge incorporates plasma protein surrogates (including GDF-15, PAI-1, and smoking-related methylation signals) that are biologically proximal to neuroinflam
