The findings come amid larger efforts to develop a cheap, simple test that can diagnose Alzheimer’s without forcing people to undergo expensive or invasive exams.
A new study shows that a simple blood test can outperform traditional exams when it comes to determining whether Alzheimer’s is responsible for memory problems, accurately diagnosing the disease about 90 percent of the time.
The encouraging findings come amid larger efforts to develop a cheap, simple blood test that can quickly diagnose patients with Alzheimer’s without forcing people to undergo more expensive and invasive exams, such as spinal taps.
The authors measured the level of p-tau217, a type of protein that builds up and impairs the brain in Alzheimer’s patients, and amyloid beta, another protein that is considered a biomarker of Alzheimer’s.
