A blood test for Alzheimer's??? Not so fast....

A blood test for Alzheimer's??? Not so fast....

Nature Medicine published a study reporting how in a cohort of 500 someodd adults -- average age in their 70's -- a blood measure of various lipids predicted the group who, over three yeas of follow up, was likely to develop either mild cognitive impairment or Alzheimers' disease dementia. I spoke with NPR's Science Desk Correspondent Jon Hamilton about this test. It's not yet ready for clinical practice but it is a great entre into thinking about Alzheimer's disease's future in desktop medicine.

The story's wide dissemination shows how the topic of predicting Alzheimer's captures our collective interest in Alzheimer's, especially the topic of learning whether you "have it" even before you "feel it." 

Minnesotta Public Radio's The Daily Circuit devoted a whole show to this subject.
