Reddit mentions of Life LInk Response Medical Alert System for Seniors LLR-300

This is a terrible disease and I'm so sorry you and your family are going through this. Home is generally more comfortable and easier on the person with Alzheimer's/dementia , but can't be done without support eventually.

To the best of my knowledge medicare will not pay for year round home health care. They will pay for it when needed for a nurse (normally involving injuries that need dressing), physical therapy after a fall, occupational therapy, or speech therapy. Medicare also limits the amount of visits for these annually. Medicaid (for lower income) often will pay for home health so it's worth checking to see if she qualifies.

If your mother or a spouse of hers was in the military she may qualify for assistance from the Veterans Affairs office which can include money to pay for help, as well as home health workers. While this is somewhat based on her income and service of the veteran, they allow you to "back out" any medical costs before declaring income making many qualify.
It's a headache to set up, and can take months but can make a huge difference.

Check ALZ.org for local groups as some towns have day trip groups and other things that can add excitement to her life as well as adult day care etc. eldercare.gov may be of help as well.

I also recommend setting up a network of friends and family. Yours, hers, neighbors etc. I sent out an frantic blanket email at a really difficult time asking for people who would be willing to give me a soft commitment to see my S.O. Who has Alzheimer's once a month and stay for an hour or two. I try to stagger them so there is one per week, he gets visitors, I get time away and there are extra people to notice changes.

If she has not been diagnosed yet it might be worth it to apply for long term care insurance before having the official diagnosis. She may not get it or it may been insanely expensive, but unless she lives with family she is most likely going to assisted living (medicare doesn't cover at all) before being ill enough to qualify for a nursing home (may not be a nice place). The financial costs of this disease are staggering and long term care insurance would be handy if possible.

Eventually you will probably want a formal diagnosis as it may help doctors to provide and agree on the most effective treatments. Just to prepare you the most effective treatments are not very effective in my experience , but for all I know they have made a huge difference in the way things have turned out for us as I can't compare it to no treatment.

When my SO was first diagnosed we used this pill dispenser. It rotates so only that doses pills are available and beeps until it is turned over so the pills come out. It's not foolproof but it worked for us. I bought a bowl that looked like none of our other ones and would check it to make sure pills weren't there. The clear lid lets you see skipped doses that were not dumped. Now I use it to keep me from forgetting to give a dose! (I don't work for any product I post here and get nothing from suggesting them)

Medalerts are also helpful for people living alone or left alone for periods of time. We used one from a company that monitored it for a time (life alert) but after many accidental alerts and ambulances showing up we switched to this one which is basically a base with speaker and mic that plugs into a landline and a pendant with speaker and mic that acts like a cordless phone. When pushed the button is set to call 4 programmed numbers and if no one answers it will dial 911. No monitoring fees, No false alarms since and when it's not urgent I can talk to him and calm him down while I make my way to him. When it is urgent I can hang up with him and call 911 for him and give actual information such as address medications etc.

When we were hit with this I was shocked that medicare didn't cover assisted living, as well as many other things. I still can't believe that a disease that is the 6th cause of death in the US has very little in the way of a social net. Please reach out here or PM me any time even if you just need to scream into the void.
