My mother in law is genetically predisposed to Alzheimer's, I know because I had my husband tested and he is positive for two copies of the apoe4 variants. His grandfather (my MIL's father) died of dementia.
My MIL has recently started to get pretty combative with me. She insists I tell her things I've never told her. We were at the park a few days ago and she went up to a random woman and started asking her questions, then came back to me and said, "You told me that was your neighbor's nanny!!" I definitely didn't, but she kept insisting I did.
This is just one instance. It's probably happened over 15 times now that she brings up something I told her, that I literally never said. I try to discuss this with my husband but he just gets upset. Here's the thing - she seemingly only does this with me. She definitely doesn't do this with my husband, who she's much more friendly to.
She is 75, eats very poorly and does not exercise. I'm a nutritionist and know the importance of diet, exercise and overall healthy lifestyle for prevention, but my husband thinks she would never even try to change.
I really want my mother in law to live a long, healthy life. I want my son to grow up with her and my husband would be devastated if she developed dementia like his grandfather. Is there anything I can do? Am I overreacting?
