CBNNews.com - A new test makes it possible for early detection of Alzheimer's in the elderly.

In a large study, researchers at the University of Pennsylvania School of Medicine studied the spinal fluid of Alzheimer's patients.

The test focused on levels of two proteins in the spinal fluid, which are attributed to damaging the brain.

Researchers say the test can help keep track of the progression of the disease and could lead to better strategies for treating patients.

There are 26 million people worldwide who suffer from Alzheimer's.
