Researchers: Blood Test Could Predict Alzheimer's in Elderly Patients
Updated: Friday, March 14 2014, 11:56 AM EDT
It's one of the worst diseases that strikes citizens by any standard. It steals their memory, erases names, faces, family and friends, basically the victim's life -- and claims a half million lives a year.
Now researchers have developed a means of determining those most at risk for this culprit – Alzheimer's disease. In a first-of-its-kind study a simple blood test was able to predict who would get Alzheimer's. The researchers looked at the blood of healthy elderly people, checking for 10 fatty molecules called lipids. Those who had lower levels of lipids were more likely to develop Alzheimer's, or the memory problems which precede Alzheimer's.
On average the change from healthy to sick took just two years, and the test was over 90% accurate.
The researchers, and the Alzheimer's association, point out that other labs need to validate that this test really works, and even if all goes well, the test won't be in doctors' offices for several years.
