Blood Test May Predict Alzheimer's Disease

Alzheimer's experts are optimistic that a new type of blood test could one day allow doctors to accurately predict one's risk of developing the degenerative disease.

While prior research has suggested that imaging techniques and tests on spinal fluid could also be used to predict the risk of Alzheimer's, a study in published in the current issue of the journal Nature Medicine suggests that this goal could be accomplished with a simple blood draw.

Such a test, if proven effective, would be less costly than imaging techniques and less invasive than a spinal tap.
