New blood test to detect early signs of Alzheimer's disease BERLIN, Apr 7: Scientists have developed a new blood test for Alzheimer's disease that can detect early indicators of the disease long before the first symptoms appear in patients. The blood test would thus offer an opportunity to identify those at risk and may thereby open the door to new avenues in drug discovery, said the researchers from Ruhr University Bochum in Germany.(PTI) DAILY EXCELSIOR, JAMMU SUNDAY, APRIL 8, 2018 (PAGE 15) DIP/J-78-P/18 Dated: 06-04-2018 DIP/J-276/18 Dated: 7-04-2018
