Donanemab-mediated amyloid plaque clearance reduces microglial activation and neuronal injury, attenuating trans-synaptic tau propagation. With reduced neuronal damage, p-tau217 release declines. This mechanistic pathway is biologically plausible but the causal chain (amyloid clearance → reduced neuronal injury → decreased p-tau217) remains unproven. Correlation of temporal sequence does not equal mechanistic causation.

Dimension Scores
How to read this chart:
Each hypothesis is scored across 10 dimensions that determine scientific merit and therapeutic potential.
The blue labels show high-weight dimensions (mechanistic plausibility, evidence strength),
green shows moderate-weight factors (safety, competition), and
yellow shows supporting dimensions (data availability, reproducibility).
Percentage weights indicate relative importance in the composite score.
