My F-I-L is going through a very similar situation... tough stuff to deal with, especially for my M-I-L... aside from the dementia, he is pretty healthy, except for severe hearing loss... makes it tough to communicate...
Keep 🙏🏼 and trying to be as supportive as you can...
My late Unreal Brother (not to be confused with my Real Brother who is still living) passed away from Lewy Body Dementia, suffering for over three years with it. It didn’t have much meaning to me until the day we were talking on the phone and he said, “Who did you say you are?” It broke my heart.
I was relieved when he passed, but not any more than those who had to care for him. He’s free, now, and has his mind back.
My F-I-L has the hearing loss, but fortunately my M-I-L isn’t much better so she just looks at him and nods.
