New Clue to Alzheimer's Found
from the Atlanta Journal-Constitution (Registration Required)
Researchers have uncovered a new clue to the cause of Alzheimer's disease.
The brains of people with the memory-robbing form of dementia are cluttered with a plaque made up of beta-amyloid, a sticky protein. But there long has been a question whether this is a cause of the disease or a side effect.
... Now, researchers have caused Alzheimer's symptoms in rats by injecting them with one particular form of beta-amyloid. Injections with other forms of beta-amyloid did not cause illness, which may explain why some people have beta-amyloid plaque in their brains but do not show disease symptoms.
