Alzheimer's Disease as Silent Displacement Accumulation: Amyloid, Tau, the Glymphatic Gap, and the Cognitive Ground State

Alzheimer's disease (AD) is the leading cause of dementia, accounting for 60--70\% of cases globally (World Health Organization (WHO), 2023). We apply the displacement framework to AD pathophysiology, identifying the normal cognitive configuration as the ground state and tracing four compounding displacement mechanisms: (1) the amyloid cascade --- amyloid-beta (A$$4 carriers would substantially delay or prevent clinical onset.
