Groundbreaking research shows that a simple blood test can flag Alzheimer’s Disease (AD) symptoms up to 15 years earlier, reports the Times of London.
Neuroscientists from the University of Gothenburg in Sweden have found a way to test only the remnants of a protein known as phosphorylated Tau 217 (pTau 217), which is usually associated with a disease known as phosphorylated Tau 217 (pTau 217) — with “amazing” results.
The test procedure – called an assay – was created by the company ALZpath and offers a painless, cheaper alternative to spinal taps to get an idea of a person’s disease risk, according to a study published in the Journal of the American Medical Association.
“The ALZpath pTau217 test can help healthcare providers determine the presence of amyloid plaques in the brain — a hallmark of Alzheimer’s disease,” said Dr. Andreas Jeromin, chief scientific officer of ALZpath.
Three independent clinical studies of 786 patients showed that ALZpath delivers “high diagnostic accuracy” in the identification of AD-inducing proteins in the brain such as amyloid plaques.

The company announced that its latest discovery will be available for clinical use by the end of January and will also be commercially available – CNN reports prices between $200 and $500 – at some point as well.
“This is an important discovery in a blood-based biomarker for Alzheimer’s, paving the way for the clinical use of the ALZpath pTau 217 test,” researchers Kaj Blennow and Henrik Zetterberg stated in a statement, adding that the “robust” test is already in use in various laboratories around the world. the world.
“What’s amazing about these results is that blood tests are just as accurate as advanced tests like cerebrospinal fluid tests and brain scans that show Alzheimer’s disease pathology in the brain,” lead author Nicholas Ashton told CNN.
“Now we are close to this test being prime time and this study shows that.”

Last year, the Massachusetts Institute of Technology designed a peptide – a chain of amino acids – to interact with and repair the brain’s tau protein as well.
Separate research also found that taking multivitamins can prevent dementia as well.
