根據一項由加州大學戴維斯分校(University of California, Davis)阿茲海默症中心(Alzheimer’s Disease Center)和加拿大維多利亞大學(University of Victoria)共同執行的大型研究指出,相較於人口學特質(如族群 [ethnicity] 等),早期的生活經驗,如:孩提時的社經狀況和素養,對晚年的認知缺損有更大的影響。

提出的新挑戰則是,現在 FDA 核准的藥物都是鎖定類澱粉蛋白質為目標,還有一大堆同類的藥正在燒鈔票試驗中,但是新研究對於類澱粉斑塊致病假說是一記強而有力的警鐘。或許 Tau 蛋白質的角色一直被誤解了,它才是真正的幕後黑手?又或許根本不需要保護整個腦,只要想辦法保住關鍵腦區或必要的神經元通道,就可以對抗阿茲海默症?這些問題都是接下來研究的重點。
