如果大多数老年性痴呆是遗传性的,研究人员能对有关家庭成员提供什么建议?约翰斯·霍普金斯大学医学院的Donald Price说,此病可遗传给许多家庭成员并不奇怪。对此病的研究公开发表后,几年来收到几千封询问信,其中包括一些家族。这些人说,我们家族似有这种病,我和孩子们有什么危险?Price说,即使有危险,也不会得病,因为不能活到那么大年龄。Folstein对此持相同观点。他说:“人活到很大年纪的可能性不大,所以老年性痴呆病人的兄弟姐妹或孩子患病的危险性很小,约在17％的范围内。”
If most Alzheimer’s dementia are hereditary, what advice can researchers give to family members? Donald Price, of the Johns Hopkins University School of Medicine, said the disease can be passed on to many family members. After the publication of the study of the disease, several thousand letters of inquiry were received over the years, including some of the families. These people say that our family seems to have the disease and what are the dangers I and the children have? Price says that even if it is dangerous, it does not get sick because it can not live to that age. Folstein holds the same view. He said: “People are unlikely to live to a very young age. Therefore, the risk of illness of siblings or children with Alzheimer’s disease is very small, about 17%.”
