It could be as simple as doing a little research for her and making some calls - relatively easy with the internet. Look up local services she may qualify for. Facilities. Supports. If she’s a member of a faith community, see if they offer any volunteer services (ie like drives to appointments or a pickup for an activity).
When my MIL got Alzheimer’s, and was still relatively functional, I was amazed what she qualified for at no or a nominal cost to her. She had a visiting social worker, a nurse, physiotherapist (she’d broken a hip) but best of all was a housekeeper 5 half days a week. That was brilliant. The housekeeper made her breakfast, made sure she bathed a few times a week, made and left a lunch, cleaned up her little apartment, did the laundry, and took her shopping. We had Meals on Wheels bring her dinner 7 days a week. We arranged for a tab with a cab company for MIL when she could no longer drive.
With all of this, and family support we were able to keep her home for almost 2 years. I had done all the research about care facilities, and put her name on waiting lists for not for profit assisted living, so we were ready when she needed it.
