Blood test for Alzheimer's diagnosis

30th October 2006

Researchers at a London university have said that they hope to be able to produce a blood test to diagnose Alzheimer's disease.

According to the scientists at King's College, London, they have discovered a breakthrough in the monitoring and diagnosing of the disease.

Speaking to the Today Programme on BBC Radio 4, the study's lead researcher Professor Simon Lovestone said that the current method of diagnosis, memory tests, is inadequate.

"This is not a very good way of diagnosing Alzheimer's disease, it's not very sensitive and monitoring progression is even harder," he said.

"What we've found is that the blood of people with Alzheimer's disease is different to the blood of elderly people or even people with other non-Alzheimer's disease dementias."

He said that the next stage of research would be clinical trials, which should take between two and five years to complete.
