Scientists uncover possible dementia detection method

A simple blood test could offer an accurate way to diagnose the development of Alzheimer's disease, it has been claimed.

In a new scientific study conducted by researchers from UT Southwestern Medical Center in Dallas, it was found that a set of proteins found in the blood serum could hold the key to early dementia diagnosis.

When combined with a clinical exam, analysis of these proteins produced a 94 per cent accurate result in detecting the development of Alzheimer's disease.

It was also 84 per cent effective at ruling out a dementia diagnosis.

"This research uses a novel technology that makes it possible to analyze several biomarkers in a single blood sample in a cost-effective way. Having a diagnosis is an important step," said study lead author Dr Ramon Diaz-Arrastia.

Currently, around 820,000 people in the UK are affected by one form of dementia or another, according to studies conducted by the Alzheimer's Research Trust.
