London: Scientists have developed a new blood test which they claim could help diagnose people showing early signs of Alzheimer`s disease. Experts have always felt that a blood test is the Holy Grail for research, as it would allow patients to be diagnosed earlier and given drugs that can slow the disease down Alzheimer`s disease. Now, an international team, which has developed the blood test, says it works by measuring levels of a hormone in the brain which may begin to decrease in those suffering with the most common form of dementia.
"This test also allowed for differential diagnosis of early stages of Alzheimer`s, suggesting this can be used as a test to diagnose the disease in its infancy," Dr Vassilios Papadopoulos, who led the study at McGill University HealthCentre in Canada, said. PTI
Dr Papadopoulos said that, until now, there had beenno way of definitively diagnosing Alzheimer`s disease besidespost-mortem analysis of brain tissue. "Our clinical study shows that a non-invasive bloodtest, based on a biochemical process, may be successfully usedto diagnose Alzheimer`s at an early stage and differentiate itfrom other types of dementia," he said. He said a test was needed that would work alongsideother ways of checking for Alzheimer`s, such as family historyof the disease, mental assessments and physical examinations. Experts have welcomed the research but were cautious. Dr Simon Ridley of Alzheimer`s Research UK wasquoted as saying, "This poses a new wayof testing blood to diagnose Alzheimer`s, but more researchmust be done." A spokeswoman for the Alzheimer`s Society added:"Research about the blood test is in the very early stages.Much more research is needed to confirm findings and betterunderstand whether the test could provide useful informationabout the diagnosis or progression of Alzheimer`s disease." The findings have been published in the `Journal ofAlzheimer`s Disease`. PTI
