Research by scientists at the University of Miami has revealed a handful of genes and genetic variants appear to be linked to Alzheimer’s disease in just one biological sex or the other. While the actual importance of these factors has yet to be unpicked, and the study only looked at white participants, the team says it underscores that there could be a genetic reason for differences in the risk of dementia in men and women, and the way it develops.
(Nghiên cứu của các nhà khoa học tại trường Đại học Miami đã phát hiện ra 1 nhóm gien và các biến thể gien có liên quan tới bệnh Alzheimer chỉ ở giới tính này hay giới tính kia. Trong khi tầm quan trọng của các nhân tố này vẫn chưa được làm sáng tỏ, và nghiên cứu chỉ quan sát ở nhóm người da trắng, các nhà nghiên cứu cho rằng có thể có 1 nguyên nhân về gien cho sự khác nhau về nguy cơ mất trí nhớ ở nam và nữ, và cách chúng phát triển).
