Our proposal introduces a novel therapeutic approach to treat neurodegenerative disorders such as Parkinson's disease and Alzheimer's disease. Our proposed method combines solid scientific evidence about misfolded protein aggregates' connection to these disorders with a fundamental physical principle stating that an object's resonance frequency is determined by its mechanical structure and mass distribution. Applied to molecular systems, this implies that misfolded proteins, due to their distinct tertiary and quaternary structures, will necessarily exhibit different vibrational and resonance profiles compared to their native forms. The treatment we propose uses frequency-adjusted high-intensity focused ultrasound or microwave systems to target and denature certain pathological protein clusters. Our approach intends to eliminate misfolded proteins such as alpha-synuclein from Parkinson's disease and amyloid beta from Alzheimer's disease through their specific resonance frequencies. These distinct resonance frequencies reflect variations in their structural conformations and post-translational modifications when compared to healthy proteins. This method aims to neutralize dysfunctional proteins with selective precision to prevent damage to adjacent healthy tissue. We acknowledge significant challenges ahead, notably the precise determination of misfolded protein resonance frequencies in vivo, ensuring targeted specificity, and managing the potential overload of biological clearance mechanisms.
