Rethinking Alzheimer's: Why Neurodegeneration Begins at the Physical Boundary, Not with Protein Plaques

Abstract

Decades of clinical trials targeting amyloid-beta plaques and tau tangles have yielded minimal therapeutic reversal in Alzheimer’s disease. Recent structural biology demonstrates that by the time macroscopic protein aggregates appear, the neuron’s fundamental information-processing highway—the microtubule lattice—has already collapsed. This paper examines the upstream biophysical origin of this structural failure. Microtubules operate as electrodynamic waveguides whose stability strictly depends on continuous mitochondrial ATP perfusion, intracellular electrical polarization, and microvascular thermoregulation. When these biophysical parameters fall out of coherence, tubulin polymers lose their conformational stability, leaving binding sites vulnerable to competitive displacement by aberrant protein conformers. We present evidence that the primary trigger of this neurovascular breakdown does not originate spontaneously within cerebral tissue, but is driven by persistent biophysical impedance at the body's immediate physical boundary. Incompatible dental restorations (alloys, composites, cements), craniofacial contact items (eyeglass frames, ocular lenses, bioincompatible headwear), and ambient dielectric interference induce chronic galvanic distortion and microvascular resistance. This chronic impedance forces cerebral capillary hypoperfusion, impairs convective thermal dissipation required for proper protein folding, and rapidly depletes neuronal mitochondrial energy reserves. Alzheimer’s disease is repositioned as a downstream thermodynamic consequence of chronic boundary impedance rather than an insurmountable defect of cellular aging. Therapeutic implications for restoring cerebral microcirculation and bioelectric baseline conditions are discussed.
