A new blood test that can detect Alzheimer’s disease years before it occurs

WASHINGTON (Reuters) – A simple blood test that can detect a rare form of Alzheimer’s disease is transmitted by heredity, researchers at the University of Washington School of Medicine and the German Center for Neurodegenerative Diseases report.

According to the researchers, this test investigates changes in the levels of the NFL protein, a protein found naturally in the brain, or neurons. The damaged or dead nerve cells leak the NFL protein towards the spinal cord fluid, and the protein then reaches the blood.Alzheimer’s

Previous studies have shown that the presence of NFL in cerebrospinal fluid is a strong sign of brain damage. Doctors have been bypassing this protein through spinal tap, but many patients do not want to do so.

The new test is an easy and fast test that is not definitive, and may be used in the future to investigate other brain injuries, such as traumatic brain injury, multiple sclerosis and stroke.

The results of the study were recently published in Nature .
