have to be cautious because the research needs more testing. It may be a few years before we have a test, but we are the closest we've ever been."

The optimism follows a study by the team last year, which compared protein levels in the blood of 500 Alzheimer's sufferers with those of healthy older people. They were able to identify which proteins were present in higher quantities in those with Alzheimer's.

In any case, the proposed blood test would be an improvement on the current memory test undertaken by GPs, which is not only very upsetting for patients, but also takes up to a year for a diagnosis and only spots the disease once its symptoms have set in.

Says Research director Professor Simon Lovestone: "There are hundreds of drugs in development but the costs, even for large pharmaceutical companies, are immense and almost prohibitive. "A year's clinical trial can cost 12million as large numbers of patients are needed to get accurate results. "This research could revolutionize practice because a blood test that accurately monitors progression can reduce the numbers of patients needed for clinical trials."

Agrees Professor Clive Ballard, director of research for the Alzheimer's Society: "A non-invasive blood test for diagnosing Alzheimer's disease would be of enormous significance. "Early diagnosis allows people with dementia and their caregivers to start preparing for their future."
