A new blood test reveals with 90% accuracy which people will develop Alzheimer’s disease or mild dementia within three years, according to study results in Nature Medicine.

The study involved 525 seniors. An analysis of 10 lipids predicted the cognitive conditions, the researchers discovered. They say this could improve interventions and drug development.

Further testing is needed before the test could be offered to the public. Without any proven preventive therapy, screening for dementia might be pointless, prior research has suggested.
