A prior warning for Alzheimer's

The latest Alzheimer's blood test appears to predict the disease 10 years before a clinical diagnosis could be made, researchers announced in November.

By measuring a certain brain protein, the investigators identified with 100% accuracy whether a sample came from someone with Alzheimer's. This was true even for samples taken from participants 10 years before they were diagnosed, the team announced.

California-based NanoSomiX plans to produce a commercial version of the new test. However, more expansive human trials are first needed.
