Mom has frontal lobe Alzheimer's, does that have anything to do with her change of voice?

Would your mother qualify for medicaid at some point. For with Alzheimer's her care needs are going to escalate beyond what one person can do 24/7.

How old are you ? How old is your mother? Do you have your own health insurance? Are you financially prepared to retire? You need to continue to build your own life otherwise, you might not have one when your mother dies. I've read many stories here of how hard it is to go back into the workforce after being out for a long time. Try to find some ways to make sure you are cared for as well as your mother.

FTD's are very difficult and cause sometimes drastic changes in personality and temperment. If this happens it will be nearly impossible to keep her at home. And the adjustment to facility living will be easier on her the sooner it is done. You do not want to lose your life.

Yes she does have trouble walking because her arthrits . Her neurologist called it Alzehemiers ,, thank you for your help I'll read up on it . She has her bad moments but she's ok most of the time with her temperament

Here is a bit about FTD.

I wondered if you were referring to frontal lobe dementia. It is a type of dementia that can cause personality changes in addition to other symptoms. I believe it is also called frontotemporal lobe dementia (FTD). The change in her voice from kind to strained and bossy may be part of a personality change. You may want to read about it. I suspect that what you might expect depends on how her personality is affected as the dementia progresses. I hope that the changes you see are not so bad, so that your mother will be able to stay at home for a long time, perhaps with the help of some paid caregivers so you'll be able to work.

Is her problem with walking because of her arthritis?

She is on Nameda and aricept
