New Blood Test Shows Promise in Early Detection of Alzheimer's Risk
Researchers discovered that a simple blood test measuring neutrophil levels, markers of immune system inflammation, may reveal Alzheimer's disease risk years in advance. The finding could help identify at-risk individuals before cognitive decline becomes apparent.
Blood Marker Predicts Dementia Risk
A routine blood marker tied to inflammation may reveal Alzheimer's risk years in advance. Scientists found that higher neutrophil levels—part of the body's first immune response—were linked to a greater chance of developing dementia.
Clinical Implications
This breakthrough offers potential for earlier intervention and preventive strategies for individuals at high risk of cognitive decline, allowing physicians to identify and monitor vulnerable patients before symptoms emerge.
Broader Research Context
A new study suggests blood tests measuring for pTau217 could forecast Alzheimer's progression years before it is detectable on PET scans.
