Tracking structural changes in preclinical and prodromal Alzheimer's disease: insights from amyloid‐beta pathology
Our study suggests that brain structural changes in response to Aβ pathology start decades before symptoms and may follow highly nonlinear trajectories. The initial increases in CT and decreases in MD<sub>T</sub> might be related to the space taken by Aβ and/or several other biological processes occurring during the preclinical stage of the disease, such as neuroinflammation, astrocytic and microglia activation, or brain swelling.
