Improving blood vessel health in the brain may help combat Alzheimer's
In patients with Alzheimer's disease, amyloid-beta protein fragments accumulate in the tissue and blood vessels of the brain, likely due to a faulty clearance mechanism. In experiments conducted in mice, investigators at ...

Squeezing of blood vessels may contribute to cognitive decline in Alzheimer's
Reduced blood flow to the brain associated with early Alzheimer's may be caused by the contraction of cells wrapped around blood vessels, according to a UCL-led study that opens up a new way to potentially treat the disease.

How do neurons and blood vessels "talk" to each other?
Neurons and blood vessels often traverse the body side by side, a fact observed as early as the 16th century by the Flemish anatomist Andreas Vesalius. Only over the last ten years, however, researchers have discovered that ...

Protein linked to Alzheimer's, strokes cleared from brain blood vessels
As people age, a normal brain protein known as amyloid beta often starts to collect into harmful amyloid plaques in the brain. Such plaques can be the first step on the path to Alzheimer's dementia. When they form around ...
