A BLOOD test that can accurately detect the presence of Alzheimer's disease is currently being developed by a team of scientists from Australia and Japan, with details published in Nature last week.
The purpose of the test is to see if the patient's blood plasma shows the build up of the protein amyloid-beta, a known precursor to developing the disease.
Researchers are hopeful that if the test is developed successfully, drug companies could use the data to recruit sufferers into clinical trials before irreversible damage to their brains occur.
Many pharmaceutical companies have abandoned the pursuit of drug treatment for Alzheimer's disease on account of the total failure rate in clinical trials thus far.
