A simple blood test could let you know whether you’ll develop Alzheimer’s disease.
A new study at the University at Buffalo found that doctors may be able to make predictions 16 years before symptoms begin.
Researchers are looking at the changes of a protein in the blood called neurofilament light chain, also known as NFL.
They’re testing for the changes in this protein to measure nerve cell loss in the brain.
The study is still ongoing, but 243 people were already found to have increasing levels of the protein.
So far, 13 participants have developed the disease.
