Blood Test Could Predict If Patient Will Develop Alzheimer’s Disease Years Before Symptoms Begin, Study Suggests.

January 22, 2019

USA Today (1/22, Miller) reports physicians “may be able to predict if someone will develop Alzheimer’s disease up to 16 years before they show symptoms by testing for a certain protein in the blood, new research” indicates.

        CNN (1/22, Avramova) reports researchers found that “by measuring changes in the levels of a protein in the blood, called neurofilament light chain (NfL), researchers believe any rise in levels of the protein could be an early sign of the disease.” CNN adds that the research “team measured the rate of change in NfL using a blood test in 405 individuals from across the world enrolled in the Dominantly Inherited Alzheimer’s Network – an international research effort focused on dominantly inherited Alzheimer’s disease, a rare form of the illness that represents less than 1% of all cases of Alzheimer’s, according to the National Institute on Aging.” The findings were published in Nature Medicine.
