Washington: A simple blood test has the potential to predict whether a healthy person would develop symptoms of dementia within two or three years, a promising research shows.
The test could fill a major gap in strategies to combat brain degeneration which is thought to show symptoms only at a stage when it too late to treat effectively.
“These findings are potentially very exciting,” said Simon Lovestone, a neuroscientist at University of Oxford.
“We desperately need biomarkers which would allow patients to be identified - and recruited into trials - before their symptoms begin,” Lovestone added.
Neurologist Howard Federoff of Georgetown University Medical Center in Washington, DC, and his team tested participants' cognitive and memory skills and took blood samples from them - around once a year for five years.
