we know a fair amount about prevention of Alzheimer's disease. For example, it begins

我們可以有一些預防的方法，例如

as an inflammatory process in the brain so anything that reduces inflammation is protective

初期會有腦內發炎的症狀，因此任何減少發炎機會的措施能有效保護

and that is why taking ibuprofen everyday reduces risk of Alzheimer's for example. That

例如，這就是為甚麼每天服用ibuprofen（一種非類固醇消炎藥）可以減少罹患阿茲海默的機會

is one strategy as an anti-inflammatory diet and lifestyle. We also know that education

抗發炎飲食和生活習慣是一個方法。我們也知道學習

is preventive against Alzheimer's disease and dementia and the reason for that seems

可以預防阿茲海默和癡呆症。而這似乎是因為

to be that education increases what is called neuro redundancy which is duplicative connections

學習會增加「神經冗餘」，意思是腦神經元間重複性的連結

between nerve cells in the brain. So the more connections you've got the more you can afford

所以在問題浮現之前，越活躍的神經連結表示在這方面有越多的「額度」可以扣

to lose before a problem shows up. Are there particular types of education that stimulate

那有沒有特別種類的學習可以刺激神經連結呢？

that? I think there are and one I'm sure of is changing your computer operating system

我覺得有的，而我相信有效的方法之一，可以先改變你的電腦系統

and if you can relate to that particular kind of frustration that comes for a few days when

如果你可以想像在使用新系統幾天後產生的挫折感

you've done that and you want everything back the same, you want to put your brain in that

並且想要回復舊狀，這就是你的大腦需要時常處於的狀態

state frequently, that is when neurons are growing new connections. A way to do that

那是一種神經正在產生新連結的狀態。一個可以長期做到這的方法

in an ongoing basis is to learn another language. There is very interesting evidence that people

就是學習新語言　有個很有趣的證據顯示

who speak more than one language have better brain function generally and better protection

能說超過一種語言的人通常大腦運作較好，也較不容易癡呆

against dementia. The good news is you do not have to master the language; it's just

好消息是　你不需要「精通」某種外語

the attempt to learn it. It's like running different software through the brain and that's

只要「學習」就行了　那就像是讓大腦使用不同的軟體

a good thing to do. So I think there are a lot of strategies of that sort out there that

而這是件好事。所以我覺得有很多類似這種的方法

I think can reduce the chance that you will end up with Alzheimer's disease or dementia.

可以減少罹患阿茲海默症或癡呆的機率
