Medications seem to have helped a bit. Can't be sure, for now. I'm also giving her prevagen. She has difficulty walking, and I try to be available to assist her. She'll be 81 in October, 2020 and I'm 81. My house is a small house with no room for a walker. I do have a walker I can use when I need to take her for an appointment, but she has difficulty trying to use it herself and it is too wide for our hall from the bedroom & bathroom/toilets to the living area. For now, the main problems are when she thinks her father has moved next door, or her sister who lives in New Jersey lives next door. I've read how to respond, but it's difficult for me to fib to her, though I've started just saying "I don't know....." or change the subject, which seems to help. I have a 2 acre farm and besides taking care of her, making meals, doing the laundry & other household chores, I have to take care of my livestock and poultry, buy groceries and hay and feed for the farm. Yes, this is more than a question, but I don't know if my insurance will cover assistance and we're on Social Security. Is mobility difficulty part of dementia & alzheimer's diseases?
I congratulate you for learning how to respond to her delusions of her dad and sister living next door. Although "fibbing" to her doesn't seem right, it's one of the responses we learn when living with our loved ones with dementia. Changing the subject and saying " I don't know" are also perfectly acceptable responses on your part. Because she honestly believes in what she thinks, your job is to go along with her to avoid any arguments. For us older folks, it's hard to find the energy to care for our loved one. I think you're doing what you need to do and I commend you. Being a caregiver is all on the job training, there's no user manaul.
As for the Prevagen, stop using it. The company is currently in a class action suit for false advertising. There is no scientific proof that the product improves memory or mental sharpness. This company is taking advantage of the dementia epidemic the US finds itself in.
Notify your Area Agency on Aging or your state Dept of Aging in NV. Both are a great resource for caregivers.
Good luck.
I would call you area Office of Aging and ask if they can evaluate your home. They may be able to help with resources. Medicaid in ur state may have "in home" help. O of A should be able to help you hear.
It will get harder too help your wife. Caregiving takes its tole on people. We are just not made to care for someone 24/7.
From the description of your house I think that you are going to have to make some major life changing alterations in the very near future because it does not sound like a home suitable for anyone who is disabled, your first steps should be to speak to your area agency on aging to see what resourced are available and also to speak with a lawyer and financial planner who is well versed in elder law and medicaid planning. Your local Alzheimer's society may also have some good information to help you learn about and plan for what lies ahead.
