A newly developed Alzheimer’s blood test not only aids in the diagnosis of the neurodegenerative condition but also indicates how far it has progressed, according to a study by researchers at Washington University School of Medicine in St. Louis and Lund University in Sweden.
Several blood tests for Alzheimer’s disease already help doctors diagnose the disease, but do not indicate the clinical stage.
Current Alzheimer’s therapies are most effective in early stages of the disease, so having a more accessible alternative than brain scans to gauge how far the disease has progressed could help determine which patients are likely to benefit from drug treatment and to what extent.
The new test can also provide insight on whether a person’s symptoms are likely due to Alzheimer’s versus some other cause.
The study was published March 31 in Nature Medicine.
