Melbourne researchers had conducted a study, which has raised hopes amid all to see a blood test soon sometime down the road for the human form of mad cow disease as well as Alzheimer's and Parkinson's, a recent report unveiled.

Published in the Nucleic Acids Research journal, the study had focused on prions, which is that pathogen that leads to development of diseases like human variant Creutzfeldt-Jakob disease. The same has led the researchers to identify particles or exosomes it releases.

The disease was looked upon since the same is the reason of some 200 human deaths. Also, during an attempt to kill the illness, it had in turn killed four and a half million cattle.

The researchers are very near to the development of such a test, which would allow people to donate their blood in case they are diagnosed negative for the disease. However, the only one condition would be they should be residing in the UK for long.

The test may arrive within coming five years and the research is being planned to be extended so that similar diagnosis techniques could be found for Alzheimer's and Parkinson's. "They're not infectious diseases like prion diseases, but we're looking for unique genetic signatures from these diseases to diagnose them in a similar fashion", said Professor Andrew Hill.
