Core Methodology
Key Innovation
Alzheimer's disease is the most common neurodegenerative disorder. Its pathological development is connected with the misfolding and accumulation of two toxic proteins: amyloid-beta and tau proteins. Mathematical models provide a valuable quantitative tool for monitoring disease progression. In this work, we proposed and compare a novel framework where the spatio-temporal dynamics of amyloid-beta and tau proteins is modeled based on employing either three-dimensional patient-specific geometries
Technical Framework
Based on the paper arXiv:2604.18470, this methodology introduces novel approaches to computational neuroscience and brain network analysis. The framework integrates data-driven methods with theoretical neuroscience principles.
