New spinal test for Alzheimer's is accurate but raises issues

The media reports a new spinal fluid test for signs of Alzheimer’s disease that may be able to detect it even before there are symptoms, presumably allowing the starting of medication to prevent the brain plaques and tangles from forming. Obviously, the information would have to be protected as it could lead to discrimination and insurance problems.

The Archives of Neurology link for “Meta-analysis Confirms CR1, CLU, and PICALM as Alzheimer Disease Risk Loci and Reveals Interactions With APOE Genotypes” is here.

The New York Times story (Aug.11) by Gina Kolata is here.

The story starts by reporting that the test can be 100% accurate.

The article points out that patients in research studies are not told the results of the studies.
