BLOOD tests can now predict inherited Alzheimer's disease at least a decade before clinical symptoms are evident, according to an international collaboration of scientists from Australia, UK, USA and Europe.
Researchers used the Dominantly Inherited Alzheimer Network and ultrasensitive immunoassay technology to demonstrate that cerebrospinal fluid and serum levels of a biomarker called Neurofilament light chain can identify presymptomatic stages of familial Alzheimer's disease.

The study was published in Nature Medicine at nature.com.
