Using just a few drops of blood, a new diagnostic test could detect Alzheimer's disease before symptoms appear.

Researchers have found a biomarker in the blood which can predict the early stages of the disease.

Sir Richard Faull, director of Brain Research NZ joined Wendyl Nissen on The Long Lunch to discuss the findings.

He says people with the disease have high levels of "beta-amyloid" in their brains.

"That's what kills the cells," he said.

Up until now, to actually look at that and see that in the brain, you've had to take very complicated PET scans.

He says new tests, which break through the hair, would give an indication of what the beta-amyloid levels are in the brain.
