LOUISVILLE, Ky. (WHAS11) - - A discovery by scientists could mean new hope for patients with Alzheimer's disease and their loved ones.
The journal "Nature" is reporting research about a rare genetic mutation that appears to protect against Alzheimer's.
The researchers in Iceland say the mutation appears to slow the production of the protein that's considered to be a cause of this form of dementia.
An estimated 5 million Americans suffer from the disease which has no known cure.
A Harvard Medical School neurologist says this research could help in the development of new, more promising drugs.
