From Analysis:
Do β-amyloid plaques and neurofibrillary tangles cause or result from cholinergic dysfunction?
The abstract explicitly questions whether AD's hallmark pathologies induce cholinergic dysfunction or vice versa. This fundamental causality question is critical for determining therapeutic targets but remains unresolved despite evidence that β-amyloid affects cholinergic receptors. Gap type: open_question Source paper: The cholinergic system in aging and neuronal degeneration. (2011, Behavioural brain research, PMID:21145918)
These hypotheses emerged from the same multi-agent debate that produced this hypothesis.
Enhancing NAMPT activity using small-molecule activators or NMN supplementation would restore NAD+/SIRT1/PGC1A signaling, mitochondrial biogenesis, and cholinergic phenotype maintenance—potentially reversing the causality direction by restoring metabolic resilience before tau pathology accumulates.

Title: Disruption of α7 Nicotinic Acetylcholine Receptor-APP Cross-Talk to Break the Amyloid-Cholinergic Destruction Cycle
Description: The α7 nicotinic acetylcholine receptor (CHRNA7) physically interacts with amyloid precursor protein (APP) at the cell surface, enabling β-amyloid to hijack cholinergic signaling and accelerate its own production while simultaneously desensitizing α7-mediated neuroprotec
The proposed framework presents an elegant bidirectional amplification model positioning cholinergic dysfunction upstream of both β-amyloid and tau pathologies. While mechanistically coherent, several fundamental concerns warrant scrutiny before accepting this causal hierarchy.
As of April 16, 2026, the practical answer is: plaques and tangles are unlikely to be just a consequence of cholinergic dysfunction. Human data support a model where cholinergic failure is mostly a downstream and amplifying vulnerability state, not the primary upstream lesion. The strongest reason is that anti-amyloid drugs do slow clinical decline, albeit modestly, while decades of cholinergic-targeted programs have mostly delivered symptomatic benefit, not disease modification.
