PARIS – American researchers have developed a prototype blood test that can tell with 90 percent accuracy whether a healthy person will develop Alzheimer’s disease within three years.
The test looks for 10 signatures of fatty proteins called lipids, according to a study published Sunday in the journal Nature Medicine.
It could help families of people developing the cognitive disorder make early decisions on how best to care for them and may also aid the search for treatment, the authors said.
Several years of clinical trials are likely to be needed to assess the prototype technique, the first blood “biomarker” to predict the tragic degenerative disease.
Attempts to develop drugs for Alzheimer’s have failed possibly because they are tested when the disease has progressed too far, said one of the researchers, Howard Federoff, a professor of neurology at Georgetown University in Washington.
