A new blood test has been devised by scientists who could play a decisive role in determining whether individuals have the onset of Alzheimer’s disease.
Experts from King’s College London have identified a group of ten proteins found in the blood which can predict whether people with memory problems will develop the degenerative disease in the next year, with a accuracy rate of 87 percent.
A large proportion of dementia research is being conducted to determine as soon as possible if people have the disease, and often the brain is adversely affected before making a diagnosis.
This set of proteins is being considered as a possible breakthrough because it could be very useful to improve the detection of drugs and treatments. These are especially necessary in the light of recent statistics that showed the vast majority (99.6 percent) of Alzheimer’s research has been considered failed or discontinued.
Professor Simon Lovestone of King’s College, who led the study, said: “Many of our drug trials fail because by the time patients are given the drugs, the brain has already been severely affected too
“a simple blood test could help identify patients at a much earlier stage to participate in new trials and hopefully the development of treatments that can prevent disease progression.”
While more than 1,000 patients were examined as part of these findings, larger studies that could require up to ten times this amount are now warranted, the Guardian reports.
scientists point to consolidate their results to see if accuracy rates can be increased and whether or not a misdiagnosis can be reduced.
Dr. Eric Karran, who is director of research at Alzheimer’s research UK, told the BBC this blood was a “technical tour de force”, but warned that if healthy people were reported incorrectly that develop this type of cognitive impairment, which could lead to anxiety and depression.
David Cameron recently pledged to invest more money in trials with dementia, calling him one of the greatest enemies who faced humanity.
