Is it me or her?

First, understand that your mom isn't purposely trying to exasperate you. At 92, if she didn't have dementia, it would be very unusual. She MAY be doing the best she can. What you attribute to laziness may well be apathy from depression or a symptom of her dementia.

I must tell you that 100% (yes, really) of the seniors I know who have gotten hearing aids don't wear them. That's not unusual at all. It may help this PARTICULAR problem if you make sure you're always facing her and she's watching you when you speak. It may help her. Rather than expect her to wear a hearing if, try an amplifier...just for when she's watching TV. If she can hear high volume, an amplifier will definitely help, and you can turn done the set. They're not expensive...probably about $50.

Apparently she can be alone because it sounds as though you are working. Make it a point to get out by yourself on the weekend...window shopping, the movies...lunch with a friend.

Hope a thing or two helps you.

First of all, get her one of those TV head phones. Tell her it is not negotiable. (There is nothing worse than a BLARING TV) Refusing to wear the hearing aids is pretty common. Is her manual dexterity declining so that she can no longer turn them on/off, put batteries in, etc.

Sounds like you may need to set a few ground rules about living in your home. Also, sounds like you need to contact your siblings to have them schedule rotating weekend outings with their mother so that you can have a weekend break.
