plaque

Destructive plaques found in the brains of Alzheimer's patients have been rapidly cleared by researchers testing a cancer drug on mice.

Falls may be an early sign of Alzheimer's disease, researchers report.

In a study of 125 older adults who appeared physically and cognitively healthy, two-thirds of those with large deposits of Alzheimer's-associated plaque in their brains suffered falls.

But a new vaccine that did just that suggests the theory is wrong....

WASHINGTON (AP) -- 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. Also involved are tangles of a protein called tau; some scientists suspect this is the cause....
