Arthritis drug may reverse Alzheimer's symptoms

Scientists believe they have found a way of improving brain cell communication by injecting the arthritis drug Enbrel into the necks of Alzheimer's patients. Researchers at the University of California-Los Angeles are reporting a response rate of about 90 percent. About 50 people are now been treated at a private clinic.

Enbrel is used to block a chemical that causes pain and swelling in the joints. That same chemical may be to blame for the advance of Alzheimer's.
