Scientists hail breakthrough in 'Alzheimer's blood test'
Scientists have developed a new blood test which could detect if a healthy person will develop Alzheimer's disease over the next three years. Changes in the blood may signify the early stages of the disease, researchers said in Nature Medicine.
Dr Doug Brown, the Alzheimer's Society director of research and development, said people "must be given a choice about whether they would want to know, and fully understand the implications" of a test that could predict the onset of the disease.
Scientists have developed a new blood test that could detect whether a person will develop dementia within three years.
By looking at 10 specific blood molecules, researchers from America's Georgetown University were able to test whether people would go on to develop cognitive impairment or Alzheimer's Disease - with 90% accuracy.
ITV News spoke to Dr Alison Cook from the Alzheimer's Society:
The study monitored 525 healthy over-70s for five years. During the research, 28 participants went on to develop the conditions. 46 were diagnosed at the start of the study.
A breakthrough in the quest to find a blood test for Alzheimer's will help doctors and patients "manage the disease", one of the researchers has said.
Professor Howard Federoff explained:
Our novel blood test offers the potential to identify people at risk for progressive cognitive decline and can change how patients, their families and treating physicians plan for and manage the disorder.
The preclinical state of the disease offers a window of opportunity for timely disease-modifying intervention.
Biomarkers such as ours that define this asymptomatic period are critical for successful development and application of these therapeutics.
We consider our results a major step toward the commercialisation of a preclinical disease biomarker test.
Scientists have developed a new blood test which could be used to detect early symptoms of Alzheimer's disease and whether a healthy person will develop the disease within the next three years.
Scientists believe changes in the blood are an indicator of the degenerative disease in its earliest stages.
A new study, published in the journal Nature Medicine, identified 10 molecules in blood could be used to predict with at least 90% accuracy whether people will go on to develop mild cognitive impairment or Alzheimer's disease.
Researchers from Georgetown University Medical Centre in the US examined 525 healthy participants aged 70 and over and monitored them for five years.
During the research 28 participants went on to develop the conditions and 46 were diagnosed at the start of the study.
