Alzheimer

My mother by the way she is now 87 years old and pretty good. I know that mum has a few issues, so for a few months we have tested her about everything. She forgets things, and someday she gets angry but also she is happy. We went to a specialist and he says that mum has a small problem and now she has Alzheimer. 

Now my family, brothers and sisters, guess what, yes in my family believes that in my family we will likely getting Alzheimer. One eldest sister also knows gets mad and happy, don't know why? I also believe that she also might have Alzheimer. After 60 you need to check our brain and see if anything changes.
