Blood test could detect Alzheimer's Disease years before symptoms begin.

BANGOR, Maine (WABI) - A NEW STUDY REVEALS THAT A SIMPLE BLOOD TEST COULD PREDICT IF A PATIENT DEVELOPS ALZHEIMER'S UP TO 16 YEARS BEFORE SYMPTOMS BEGIN.

THE RESEARCH FOCUSED ON A CERTAIN PROTEIN IN THE BLOOD CALLED "NEURO-FILAMENT LIGHT CHAIN", OR N-F-L.

SCIENTISTS BELIEVE ANY RISE IN LEVELS OF THAT N-F-L PROTEIN COULD BE AN EARLY SIGN OF ALZHEIMER'S.

THAT'S BECAUSE THE PROTEIN INDICATES ANY LOSS OF NERVE CELLS IN THE BRAIN.

DOCTORS CAN STUDY THE PROTEIN TO SEE IF IT'S BEING AFFECTED BY ANY PROCEDURE.
