Composite Aging Risk Score (CARS) identifies hippocampus as the primary AD vuln…

Mechanistic description

A multi-axis transcriptomic Composite Aging Risk Score (CARS), integrating neuroinflammation, DAM activation, synaptic integrity, cellular senescence, mitochondrial health, and lipid homeostasis axes, shows hippocampus carries the highest aging burden (+1.83 SD at 24 months) vs cortex (+1.41 SD) and cerebellum (−0.28 SD). A 6-gene blood surrogate panel (GFAP, TREM2, SYP, CDKN2A, APOE, TFAM) captures 83% of CARS variance, providing a translatable biomarker index for pre-clinical AD staging.
