A breakthrough blood test can now detect Alzheimer's disease years before symptoms emerge. The test, which measures specific proteins in the blood, has shown 90% accuracy in clinical trials.
"This changes everything about how we can approach Alzheimer's," said Dr. Randall Bateman, who led the research. "Early detection means early intervention, when treatments are most effective."
The test is far less invasive and expensive than current methods, which require PET scans or spinal taps. It could soon become part of routine health screenings for people over 50, potentially catching the disease when lifestyle changes and new medications can still make a significant difference.
