Predicting Alzheimer's

A new discovery by researchers in the US could change the way Alzheimer's is treated.

A blood test can predict the onset of Alzheimer's disease two to three years in advance with a 90% degree of accuracy, according to a team of researchers at Georgetown University in Washington, DC.

If confirmed by larger clinical trials, this discovery could change the way the disease is treated. Many suggest that drugs that attack Alzheimer's fail because patients are treated too late to make a difference.

Currently, the disease affects more than 35 million individuals worldwide, and that number is expected to grow to 115 million by 2050, according to the World Health Organization.
