London - Scientists have identified a set of proteins that can predict the development of Alzheimer’s disease-related dementia with 87 percent accuracy.
The new research could lead to a fast and accurate blood test for Alzheimer's disease. Alzheimer’s disease is a form of dementia that worsens over time, leading to a slow decline in cognitive functions and affecting memory, thinking, and behavior. More than 5 million Americans are living with the condition, according to the Alzheimer’s Association.
Identifying biomarkers in the blood that can accurately predict whether a patient will develop Alzheimer’s disease is a major research goal in science. According to the Guardian, an international group of researchers have found that a panel of 10 proteins shows a high level of predictive power.
Simon Lovestone of King’s College London and the University of Oxford and his colleagues analyzed the blood of 452 healthy people, 220 with mild cognitive impairment, and 476 with Alzheimer’s disease. From this, the research team were able to identify those who would develop cognitive impairment in the next year with 87 percent accuracy.
Although the results are promising, in reality a practical blood test for Alzheimer's disease remains several years away. One of the researchers, Ian Pike, chief operating officer at Proteome Sciences, told BBC News: "It will take several years and we need many more patients before we can be certain these tests are suitable for routine clinical use."
The findings have been published in journal Alzheimer’s & Dementia. The research is titled "Plasma proteins predict conversion to dementia from prodromal disease."
