 A combined blood test for cognitive decline has a 90% accuracy rate in determining whether memory loss is due to Alzheimer’s disease, a new study found.

In comparison, neurologists and other memory specialists correctly diagnosed Alzheimer’s in 73% of their cases. Primary care doctors had even less success, with only a 61% accuracy rate, according to the study.
