"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.
Early diagnosis would also allow people to develop a care plan to reduce the burden on the patient and their family, she said.
She said that a blood test would be the ideal first stage to help identify people at risk before a diagnosis is confirmed with cognitive tests and brain scans.
The research has been published in the journal Molecular Psychiatry.
