Asymptomatic Alzheimer’s disease brains show amyloid burdens comparable to AD but fewer compact plaques, lower tau burden, and more restricted TDP-43 pathology.
- Why it matters: Molecular mechanisms of resilience in Alzheimer’s disease are understudied, despite evidence of resilient individuals and cross-cohort multiomics datasets.
- What they did: The study integrated longitudinal cognition, regional neuropathology, and matched prefrontal proteomic and metabolomic profiles across donors from two independent cohorts.
- The result: Across matched amyloid, tau, and TDP-43 stages, resilience in AsymAD is linked to preserved mitochondrial translation and bioenergetics, synaptic programs, glutamatergic metabolites, and polyunsaturated membrane lipids, and longitudinally separates resilient from vulnerable AsymAD.
