How do cytoskeleton and autophagy pathway dysregulations causally link sarcopenia and AD pathogenesis?

OPEN

The authors suggest these pathways contribute to both conditions but provide no mechanistic evidence for how shared dysfunction leads to muscle and brain pathology. This gap limits understanding of the biological basis underlying sarcopenia-AD comorbidity. Gap type: unexplained_observation Source paper: Uncovering polygenic and local genetic overlap between sarcopenia and Alzheimer's disease. (2026, J Alzheimers Dis, PMID:41940827)
