A week ago, a mother who is interested in having her daughter learn Chinese from me told me that learning a foreign language can prevent Alzheimer’s disease. I had sometimes worried that my language skills would deteriorate in old age. I thought I would lose my English and revert to my mother tongue which is Chinese. Since my husband is an American who does not speak Chinese, I thought I’d better teach my children Chinese so they could talk to me when I am really old. But this mother reassured me that I will be all set and won’t have memory problems since I speak three languages: Chinese, English, and French.
I googled on “foreign language and Alzheimer’s” and found several articles on how learning a foreign language can help prevent memory loss:

Learning a Foreign Language Can Help You Live Longer
[Dr. Andrew] Weil believes that by learning a foreign language we can reduce the risks of getting some of the most common age-related symptoms and diseases such as memory loss and Alzheimer's. “You don't have to master it,” he said. “Just the attempt to learn a language is like running different software through the brain. You're exercising more communication channels in the brain.”
