Research Question¶
How does the human brain connectome reorganize in Alzheimer's disease, and what are the vulnerable hub regions that drive network-wide disintegration? Does connectome breakdown precede or follow amyloid/tau pathology, and can graph-theoretic measures of connectome integrity serve as early biomarkers of neurodegeneration?
