万一自己将来得了老年痴呆，现在应该怎么未雨绸缪得病后的生活？对子女有什么期待？

阿尔茨海默病可以从父母任何一方遗传，但如果从母亲遗传，风险可能更高：

Alzheimer's disease can be inherited from either parent, but the risk may be higher if it's inherited from the mother: 

Genetics

People inherit one copy of the APOE gene from each parent. Inheriting at least one copy of the APOE e4 allele from either parent increases the risk of developing Alzheimer's disease. Inheriting two copies, one from each parent, increases the risk even more. 

Family history

People with first-degree relatives who have Alzheimer's disease are four to 10 times more likely to develop the disease themselves. 

Maternal inheritance

Some studies suggest that the chances of inheriting Alzheimer's disease are higher from the mother than the father. For example, one study found that people with a mother who had Alzheimer's disease had twice as much gray matter shrinkage as those with a father or no parent with Alzheimer's. 

While genetics is a factor in Alzheimer's disease, there are many other risk factors that can contribute to the disease, including behaviors and habits. Some of these risk factors can be changed to potentially reduce a person's risk of cognitive decline.
