Researchers may have come up with a new way of diagnosing Alzheimer's disease.

FOX's Colleen Cappon reports in this edition of "Housecall for Health":

There's no effective treatment for Alzheimer's, but doctors may soon be able to diagnose the disease with a blood test.

Researchers in Germany have developed a new technique that analyzes genetic material floating in the blood. By utilizing these biomarkers, they've been able to diagnose Alzheimer's in trials with 93% accuracy.

The definitive test could detect the condition before symptoms start, and eventually make early treatment more effective.
