There is encouraging news about treating Alzheimer's. Researchers at UCSF say a simple blood test seems to predict who will develop cognitive problems years before symptoms emerge.

A study of nearly 1,000 Americans found that people with very low levels of a certain type of protein in their blood showed statistically significant cognitive declines over a nine-year period compared with people who had higher levels of protein.

The study is in the Journal of the American Medical Association.
