The most credible disease-modifying model is that trazodone must reach a higher exposure range, likely around 150-200 mg/day, to engage the PERK-eIF2alpha integrated stress response in neurons and restore translation. This remains a mechanistically grounded but unvalidated human threshold derived mainly from preclinical tauopathy/prion data and supported by the observation that many real-world dementia prescriptions were likely below this range.

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.
