Scientists Develop Computer Model to Simulate Alzheimer's Disease Spread in Brain
Researchers have created a new computer model that simulates the spread of Alzheimer's disease through the brain, highlighting the impact of the brain's physical structure on disease progression. The study, published in the journal Computer Methods in Applied Mechanics and Engineering, combines the movement of toxic proteins, such as amyloid-beta and tau, with the brain's structural changes as the disease advances. This model aims to provide a deeper understanding of how microscopic changes lead to large-scale brain damage. The model incorporates the brain's white matter fiber tracts, which serve as routes for disease spread, and accounts for the brain's physical deformation due to tissue atrophy. The simulations have shown good agreement with real-world disease progression, suggesting the framework captures important features of Alzheimer's.
