A blood test, called Binding of Soluble Oligomers (SOBA) can detect toxic proteins and signs of Alzheimer’s years before the first symptoms appear, confirmed the University of Washington.
Most patients are diagnosed with Alzheimer’s only after they develop memory problems, But an early sign of the disease comes from clumps of a protein called “amyloid beta” that build up in the brain.
The proof it also identified people who would develop cognitive impairment up to a decade before diagnosis.
Although the blood test needs to be tested in many more people and is still in an early stage, bioengineer Valerie Daggett, who developed the test, said: “What doctors and researchers wanted is a reliable diagnostic test for Alzheimer’s disease.”.
the new test Focuses on “Amyloid Beta”the proteins that are a red flag for Alzheimer’s disease.
When people develop Alzheimer’s disease, proteins in the brain fold incorrectly, forming “alpha sheets” that stick together in groups.
The proof uses synthetic alpha sheets to extract “amyloid beta” of someone’s blood and show how much is in their body.
