Scientists think they have found a marker that can detect who will get Alzheimer's disease five to 10 years before its onset.

The indicator of trouble is a shift in the levels of specific components of the cerebrospinal fluid in the brain and spinal cord.

Researchers found a drop in such levels appears to be a sign of Alzheimer's years before symptoms develop.

The discovery published in the Archives of General Psychiatry could potentially aid in the use of therapies that would slow or stop progression.
