Blood test may predict Alzheimer’s disease


It’s a devastating disease that debilitates around three million Americans.

Now, a new clinical study hopes to be able to predict if you’ll develop Alzheimer’s.

A simple blood test could let you know whether you will develop Alzheimer’s disease.

According to a new study published in the journal, Nature Medicine, doctors may be able to make predictions, 16 years before symptoms begin.

One of the many changes in the brain that occur is the accumulation of a protein in the blood called neurofilament light chain, or NFL, but doctors are unsure what causes someone to get the disease.

Researchers are testing for the changes in this protein, to measure nerve cell loos in the brain.

They say the more NFL in the blood, the more brain damage you have.

Four hundred and five people across the world were part of the “dominantly inherited Alzheimer’s network”.

Their NFL protein levels were measured through blood test, brain images, and cognitive tests every two and a half years, over the last seven.

This is an ongoing study, but 243 were already found to have increasing levels of the protein. So far, 13 participants have developed the disease.

If this clinical trial proves successful, doctors are hopeful it will allow them to start treating patients early.
