A Blood Test for Alzheimer’s?

CNN ran a story last week about a blood test that detects Alzheimer’s. Blood test could detect Alzheimer’s up to 16 years before symptoms begin, study says starts with an explanation of the “technical” aspects where the test would “measur[e] changes in the levels of a protein in the blood, called neurofilament light chain (NfL) [which] researchers believe [with] any rise in levels of the protein could be an early sign of the disease…”  The study is in the most recent issue of  Nature Medicine.

This is not a cure, but there are advantages to knowing this far in advance that the person has Alzheimer’s.  For starters, as the story notes, it would help with testing of treatments. From a legal point of view, it may encourage more clients to plan.
