Researchers in Japan have confirmed that a blood test can accurately predict the onset of Alzheimer's disease. Professor Iwatsubo Takeshi from the University of Tokyo and his team published their findings in an international medical journal: Amyloid beta, an abnormal protein, is known to accumulate in the brains of Alzheimer's patients long before symptoms become apparent. At present, Alzheimer's is diagnosed using methods such as brain-imaging tests. The researchers analyzed blood samples from 474 individuals in Japan who had not developed the disease and compared the results to diagnoses obtained from brain imaging.

Scientists say they were able to predict amyloid status in the brain with high accuracy through blood analysis of two proteins -- amyloid beta and tau phosphorylated at threonine 217, or p-tau217. They say that by adding other information, such as the age of the individuals, the blood tests showed an accuracy rate of over 90 per cent in predicting amyloid buildup. Professor Iwatsubo said new Alzheimer's drugs have recently been approved for use in the early stages of the disease.
