Activity-dependent epidemic spreading on multiscale brain networks predicts Alzheimer's disease progression

The results connect epidemic theory to neurodegeneration, implicate neuronal activity as a driver of Alzheimer's disease progression, and motivate activity-modulating therapies to slow or prevent pathological spread are connected.

Hysteresis and multistability in network spreading with neuronal activity feedback

It is shown that nonlinear feedback can fundamentally change the invasion dynamics in a susceptible--infected--susceptible spreading process coupled to a co-evolving activity process, and that feedback from activity processes can create hysteresis and multistability in network spreading dynamics.
