Scientists say a new blood test could detect Alzheimer’s disease three years before the patient develops symptoms of memory loss.

The study, published in the journal Nature Medicine, identified 10 molecules in the blood that predicted Alzheimer’s with 90% accuracy. Researchers wrote the bloods tests “can change how patients, their families and treating physicians plan for and manage the disorder.”

On the other hand, experts warned the Guardian that a test for an incurable disease with a 10% rate of error would have to be approached with caution, both by the doctor and the patient.
