SOBA: Development and testing of a soluble oligomer binding assay for detection of amyloidogenic toxic oligomers. Proc Natl Acad Sci U S A. 2022 Dec 13;119(50):e2213157119. doi: 10.1073/pnas.2213157119. Epub 2022 Dec 9. PMID: 36490316.Alzheimer’s is the most common neurological condition to affect seniors, with nearly 1/10 diagnosed. The problem with Alzheimer’s is there is no test for it. To get a diagnosis you have to first rule out all the other possible diseases and this takes months if not years.
Researchers at the University of Washington developed a test called SOBA that looks for clumps of a certain protein in blood and cerebrospinal fluid. SOBA correctly identified 52 of out 53 people with Alzheimer’s and even detected Alzheimer’s who had not yet shown signs of it.
