| Is it true that blood test capable of detecting Alzheimer's? |
Once able to be detected through detection of drug substance called amyloid Amyvid, scientists are now finding new ways to detect Alzheimer's. Based on the researchers at Emory University, is now a blood test can be used to detect Alzheimer's.
"The accuracy and failure has been the biggest challenge in this field. Yet our research shows that we can find consistent results," said William Hu, an assistant professor at Emory University School of Medicine who led the study.
Hu and his colleagues at the University of Pennsylvania and Washington University, St. Louis, to measure levels of 190 proteins in the blood of 600 participants in the study.
The participants were healthy people and people who have been diagnosed as having Alzheimer's disease or mild cognitive impairment (MCI).
Usually Alzheimer's can only be known through clinical symptoms, such as PET brain scans are usually expensive, or painful spinal analysis.
"Although a blood test to detect Alzheimer's disease is still not ready to be implemented with current technology, we have been looking for ways to make this test can be done," said Hu as reported by the Health Me Up (13/08).
"Meanwhile, the combination of clinical examination and analysis of cerebrospinal fluid is the safest way and good for diagnosing early symptoms of Alzheimer's," he added.
