New brain model links blood flow to Alzheimer's protein spread

Alzheimer's disease is not only about the accumulation of toxic proteins in the brain.

A growing number of studies indicate that the health of cerebral blood vessels may also play a decisive role in the onset and progression of the disease.

A reduction in blood flow, vascular damage and the accumulation of amyloid beta, one of the key proteins associated with Alzheimer's, in fact feed into one another in a pathological cycle. ...
