My MIL moved in with us (we have a detached living quarters to our home) and her daughter insists our 95 yr old mom has Dementia. Mom has lived with us 2 months and doctors, friends are amazed with this woman. She has to do a flight of stairs to get to apartment, shows no signs of dementia and is a joy. Gets up each day, fixes her coffee, do makeup, hair, dress etc. And she has what I call normal memory for being 95, great recall uses a cellphone even though it is frustrating, engages in conversations. She had some medical issues (a minor TIA from untreated high BP) so we've seen a neurologist and he said she follows directions and doesn't have dementia. She had not been taking her medications while living with daughter for her blood pressure and had been under a lot of stress. But we've been able to get her health back. There is a lot more about the situation but we're going to be going back to where the sister lives (110 miles away) to get moms house ready for sale soon. The siblings do not get along and I just am not good at figuring out what to say.
