Early noradrenergic loss may shift inflammatory tone, amyloid clearance, and cholinergic resilience, thereby modulating the observed sequence of biomarkers. The debate supports this mainly as a stratification axis and covariate rather than a primary causal program.
AD-risk trafficking defects in SORL1/BIN1/PICALM/retromer may generate parallel early outputs: amyloidogenic APP sorting and selective basal-forebrain cholinergic trophic failure. This best fits the debate because it explains why temporal order can appear inconsistent across cohorts without requiring a single linear sequence.
Convergent vs Divergent Predictions
This summary checks where the selected hypotheses point toward the same target or mechanism, and where they pull in opposite directions.
