Melbourne: Scientists in Australia are working on a blood test that could lead to routine screening for Alzheimer`s disease.They have identified blood-based signs of plaque in the brain that could alert doctors to the disease long before symptoms appear and irreversible brain damage has occurred."Early detection is critical. It gives people a much better chance of receiving treatment before it`s too late," researcher Dr Samantha Burnham from CSIRO`s Preventative Health Flagship said.Dr Burnham hopes the breakthrough will lead to routine age-based testing in five to 10 years.
