A breakthrough blood test can now detect Alzheimer's disease up to two decades before symptoms emerge. The test, which measures specific proteins in the blood, has shown 90% accuracy in clinical trials.

“The test, which measures specific proteins in the blood, has shown 90% accuracy in clinical trials.”
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.
