Scientists develop a blood test that detects Alzheimer’s by measuring protein structural changes rather than protein quantity.

Researchers from the University of California San Diego have found that a novel blood-based biomarker can predict a woman's risk of developing dementia as many as 25 years before symptoms appear.

The blood biomarker p-tau217 has "shown the most promise in detecting Alzheimer's in the brain," researchers of a new study say.

Scientists say a new blood test may detect the risk of dementia decades before memory problems begin, offering a potential ...
