Blood test can predict with 90% accuracy the risk of Alzheimer's onset in the next three years

A blood test can accurately predict the onset of Alzheimer's disease, according to US researchers.

They showed that testing levels of 10 fats in the blood could predict - with 90% accuracy - the risk of the disease coming on in the next three years. The 10 markers of Alzheimer's could predict who was likely to enter mental decline in the following years.

The full power of the test has not been investigated either. So far they know a diagnosis of dementia can be predicted three years ahead of time, but the researchers are now investigating whether the test works even earlier.
