Alzheimer's-Linked Brain Plaques and Blood Flow
Amyloid beta clumps may constrict blood flow, adding to neurological woes, animal studies suggest
"The vessel has to be able to expand and contract, to dilate and constrict, if it's going to regulate blood flow," Roberson said. "If they have become rigid like a pipe, instead of having a flexible wall that can go back and forth, then they cannot do their job of regulating blood flow to the brain properly."
This research is still in its early stages, and experts note that there's never a guarantee that laboratory or animal studies can be replicated in humans. The study was funded by the U.S. National Institutes of Health and published Nov. 23 in the journal Brain.
