My grandmother is 92 and has vascular dementia. She has a mix of stage 4 and 5, some days are fairly good, other days are bad and she repeats questions/phrases, forgets what day/month/season it is, forgets what different kind of foods/sauces are and dips food in the wrong sauce normally used to dip...(eg. cant recognize gravy from tartar sauce and dips breaded fish in gravy) she still recognizes some family and friends however and long term memory is reasonably intact.

We are moving her into an extra care facility next month. I am wondering if whether we should note a more progression dementia once moved into an unfamiliar environment. I ask because she's had signs for what we believe to be 10 years but has followed such a slow progress that changes have been mild and minimal but doctors say would constitutes as moderate dementia. Could it not progress at all? Could it be a misdiagnosis of MCI (mild cognitive impairment) and my family refuses to get a second opinion?

I love my grandmother and I would wish and hope that she remains only like this and remembers us until the end, or that a medication could improve it (doctors say there's no medication to help with this dementia). Any help or encouragement would be amazing.
