Researchers are getting closer to finding a way to screen for Alzheimer's Disease before any symptoms show up. A new study of more than 200 people looked at levels of two key markers to see how they were different in Alzheimer's patients compared to healthy volunteers.
The two biomarkers are Beta Amyloid, which forms clumps of plaque in the brain, and Tau, which kills tangled brain cells. Researchers at the National Institute of Mental Health found that both the markers were abnormal in over 80% of the Alzheimer's patients. This study is in the Journal of the American Medical Association.
