DETECTION IS GOOD, CURE IS BETTER: Japan approves blood test to detect Alzheimer’s. “The blood test kit, codeveloped with Eisai, will give doctors in Japan an easy, inexpensive and minimally invasive tool to screen people quickly for the disease, which is currently done through PET scans, MRI or painful spinal taps. Convenient testing will also help physicians decide who’s qualified to receive a novel therapy — lecanemab, being developed by Eisai and Biogen — that may get approved in the U.S. early next year.”
