My husband has moderate dementia and no longer asks the same questions or any questions. He no longer can have a conversation as his cognitive processing skills have deteriorated leaving him capable of only one or two word answers to questions from me. If your husband repeats his questions there are two aspects of dementia to consider. The first is that memory is affected. Most of us know that. But there is also a second factor to consider. Cognitive ability declines with dementia. Just because he hears an answer doesn't mean he can process what is being said. If he doesn't process it, it's like not getting an answer at all, so he asks again. The biggest help to increase my patience and understanding of my husband's behavior was to learn as much as I could about his dementia. The Alzheimer's Association has many valuable articles that address this need. I have found that understanding the disease if very helpful but what I really needed was a program to teach me a positive way to interact with my husband, to learn to focus on what he can still do not what he no longer can. You can learn to still find joy in the little things. I highly recommend Teepa Snow's website: Positive Approach to Care. You will learn so much that will help you deal with this dementia caregiving journey. You have done a good thing for yourself by reaching out to others on this site who understand your pain and frustration. God bless you and your husband on this difficult journey. PS I have found that while my husband is largely non verbal still enjoys hugs and kisses and kind words. People with dementia can usually still interpret others' body language. I believe that expressing your affection is a balm for them as well as for yourself.
