Cerebrovascular and mitochondrial abnormalities in Alzheimer’s disease: a brief overview
- 680 Downloads
Multiple lines of evidence suggest that vascular alterations contribute to Alzheimer’s disease (AD) pathogenesis. It is also well established that mitochondrial abnormalities occur early in course of AD. Here, we give an overview of the vascular and mitochondrial abnormalities occurring in AD, including mitochondrial alterations in vascular endothelial cells within the brain, which is emerging as a common feature that bridges cerebral vasculature and mitochondrial metabolism.
