“(CNN)A team of scientists from Australia and Japan has developed a blood test to detect early signs of Alzheimer's disease.

The noninvasive test was developed to detect the presence of the toxic protein amyloid beta, known to be present in people affected by the disease, and did so with 90% accuracy, according to the study, published Wednesday in the journal Nature.
