Chronic methanol exposure induces cognitive impairment and Alzheimer's-like pathology in rhesus monkeys.

Chronic low-dose methanol exposure in rhesus monkeys recapitulates progressive cognitive deficits and AD-like neuropathological features. This model, driven by endogenous formaldehyde toxicity, effectively mimics key aspects of sporadic AD. Our findings shed light on the neurotoxic mechanisms of methanol and propose a reproducible and translationally relevant nonhuman primate model for studying AD pathogenesis and evaluating potential therapeutics.
