A simple blood test may soon help identify people at higher risk of Alzheimer’s disease years before they develop symptoms, according to a new study.
Researchers at the University of California, San Francisco (UCSF) in the United States, found that certain Alzheimer’s-related proteins in the blood were linked to small differences in thinking and memory among middle-aged adults who did not have dementia.
Alzheimer disease is the most common form of dementia, which results from a variety of diseases and injuries that affect the brain.
While there are drugs to ease symptoms, there is currently no cure for dementia.
The research team says this is the first time such blood markers have been shown to correspond with subtle cognitive differences in this group.
