What mechanisms explain APOE's delirium risk independent of its established dementia pathways?

OPEN

The study identifies APOE as a strong delirium risk factor independently of dementia, but the mechanistic basis for this dementia-independent effect remains unexplained. Understanding these distinct pathways could reveal novel therapeutic targets for acute cognitive dysfunction. Gap type: unexplained_observation Source paper: Dissecting the genetic and proteomic risk factors for delirium. (2026, Nature aging, PMID:41286463)
