Alzheimer’s blood test performs as well as FDA-approved spinal fluid tests (Links to an external site)
Scientists report a major step toward a simple blood test for Alzheimer’s disease. Researchers at Washington University School of Medicine in St. Louis and Lund University in Sweden showed that a blood test is as good at identifying people in early stages of the disease as cerebrospinal fluid tests approved by the Food and Drug Administration (FDA) for Alzheimer’s diagnosis. The findings indicate that a blood test soon may replace more expensive and invasive brain scans and spinal taps for detecting signs of Alzheimer’s in the brain.

A study of frozen blood samples has turned up a trove of proteins that may predict several forms of dementia more than 10 years before the disease is diagnosed, researchers from the U.K. and China reported on Monday.

Blood tests can help diagnose Alzheimer’s — if they’re accurate enough. Not all are (Links to an external site)
A new generation of blood tests is poised to change the way doctors determine whether patients with memory loss also have Alzheimer’s disease.
The tests detect substances in the blood that indicate the presence of sticky amyloid plaques in the brain — a hallmark of Alzheimer’s. So these tests have the potential to replace current diagnostic procedures, like costly PET scans and uncomfortable spinal taps.
