Blood test to predict Alzheimer's disease

Scientists have suggested that levels of the protein called clusterin rise 'many years' before symptoms of Alzheimer's disease first appear.
An early test for the condition could allow those patients could have early treatment and make improvements to their lifestyle to minimise the impact of the disease.
The study, conducted by the Institute of Psychiatry at King's College London, also found that very high levels of the protein may be linked with more rapid and severe memory loss.
Patient groups said the prospect of a blood test for Alzheimer's disease was the 'holy grail' for researchers in this area and the latest findings bring this a step closer.

My mother had Alzheimer's. I don't think I'd want to know that I would develop the disease unless there was a cure.
