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.
