Scientists said on Tuesday that the developed experimental blood test was very accurate in detecting Alzheimer’s, a promising achievement that could make the diagnosis simple, affordable and widely available.
The New York Times reported that the test was able to determine whether people with dementia had Alzheimer’s disease instead of another condition. She said he also identified the signs of Alzheimer’s disease 20 years ago of expected memory and thinking problems in people with a genetic mutation that causes fatal degenerative disease.
“This blood test predicts very, very accurately, those who have Alzheimer’s in their brain, including people who appear to be normal,” said Dr. Michael Weiner, a researcher with Alzheimer’s disease at the University of California, San Francisco.
The study was published in JAMA Network Open and presented at the Alzheimer’s International Conference.
A blood test – performed as accurately as an MRI and PET scan – provides a simpler, more affordable way to diagnose whether people with cognitive problems develop Alzheimer’s, unlike another type of dementia.
This blood test can also be used eventually to predict whether a person without symptoms will develop the disease.
Experts said that the test could be available for clinical use, within two to three years.
