Blood test for Alzheimer’s moves forward
One day it may be as easy to test for Alzheimer’s disease as it is for anemia. Researchers at the University of Nottingham in Great Britain are developing a blood test that would be able to quickly detect a specific combination of biomarkers that they believe strongly indicate a case of Alzheimer’s disease.
Most cases of Alzheimer’s disease are not diagnosed until symptoms, such as memory loss and confusion, appear. Unfortunately, by this point the brain has already sustained significant damage from the disease.
The new blood test could be used in clinics to quickly and cheaply screen for and detect Alzheimer’s disease far before symptoms begin to appear, giving doctors more time to treat the condition. The researchers acknowledge that the test is still 10 years away from being used on patients, but say that the combination of markers they found to detect the disease is very promising.
