Researchers try to 'detect' Alzheimer's

Using a device called "Detect," researchers challenge patients' memory and cognitive skills. The device uses virtual images and sounds in a helmet.

Emory University researchers say the test is quick, portable and provides consistent data to track memory loss.

Although there is no known cure for Alzheimer's, many people can offset the symptoms through brain exercises and meditation. The earlier the diagnosis, the earlier the treatment and the better the quality of life.

Scientists say they hope to have the Detect system in doctors offices as early as the coming fall season.
