Last week I went to my friend's house , and I saw her grand mother. But I feel strange with her grand ma , because I see she can not remember with well . When I asked my friend about it , she said that her grand mom has Alzheimer's disease.
When I went home , I still keep this problem in my mind and I think my mother is old now and I do not want she had this problem too. So I try to search on net how to preventing people not to have Alzheimer's disease.
