Thank you for your comments. I feel like people look at me like I have 3 heads when I pose this very question.
I heard about an "adult daycare" program near me from someone in a dementia support group. I took my 74yr old husband for an assessment, which showed severe dementia. This was simultaneously shocking and validating. He goes 3 days per week. The first two weeks he complained that they were all crazy and messed up. Now he enjoys it! He's not the same man he used to be. They meet him where he is today. He feels safe and supported, and comforted by the routine. I'm taking his to his neurologist this week for the first time since Jan 2023. I need a letter from him so that I can activate my POA for financial matters. Otherwise, I'm hoping for some advice on whether he is ready for memory care. I don't expect a definitive answer.
