也算是老年痴呆症患者和患者家人的福音吧，FDA今天批准了新药

FDA Approves New Treatment for Early Alzheimer’s Story by Pam Belluck • 5h ago

The Food and Drug Administration on Friday approved a new Alzheimer’s drug that may modestly slow the pace of cognitive decline early in the disease, but also carries risks of swelling and bleeding in the brain.
The newly approved drug, Leqembi, should be used only for patients in early and mild stages of Alzheimer’s disease, matching the status of patients in its clinical trials, the F.D.A. label says. © Zephyr/Science Source The approval of the drug, lecanemab, to be marketed as Leqembi, is likely to generate considerable interest from patients and physicians. Studies of the drug — an intravenous infusion administered every two weeks — suggest it is more promising than the scant number of other treatments available. Still, several Alzheimer’s experts said it was unclear from the medical evidence whether Leqembi could slow cognitive decline enough to be noticeable to patients.

只能在早期痴呆病人里用。只是有限地减缓了病情进展的速度而已。当然这次临床试验结果还是比上次的那个aduhelm要更靠谱一些。
