My mom's mother had dementia, and my mom's father had Alzheimer's. I'm worried that as my mom ages she will face these same problems. I also fear that because she has it in her head that she will end up like them, she a) doesn't care to take any preventative measures, and b) just her frame of mind could bring on the symptoms sooner and more rapidly. (You know how people who aren't sick can make themselves sick because they believe it?)

She's only 55, but I feel like she's having problems with her short-term memory already. She tells me the same things over and over, she doesn't remember things my family members tell her... I mean, I know she's really busy but these small things worry me.

Is there anything she can do to act in a proactive manner? Any supplements that are good for brain health? Any advice is appreciated. Thank you
