Good morning, @tavi. Short answer to the beginning of your post is 'yes'. My wife suffered from many dementia-like symptoms. Her anxiety was one of the most difficult aspects of all those symptoms to get corralled. First, I am glad your husband's doc is acting quickly. Our GP ignored it for too long, it got out of hand, and was far more difficult to address as a result. My wife was on Seroquel for a long time. I can look up the dose if it would help. Took us awhile to find the appropriate, medicinal level for her, but once we did it was a huge help. She stayed on that for years. Once at therapeutic levels it finally did help her sleep patterns too. For my wife it was a great pharmacological addition for her care, but also one the doctors were frequently adjusting in her cocktail.

From my time with the Alzheimer's Association I know 'sundowning' is very common with dementia patients. It was also a factor with my wife all the time and my mother-in-law for a time early on in her diagnosis. It abated with my MIL, but for a time we had to adjust her interactions, med schedule, and account for some tougher afternoons.

The second part of your post is a really tough one. There are so many aspects to it and it comes down to a very personal decision, which you already know will be a challenging one. My MIL stayed home with care, but she was in a bigger urban setting where more help was available and fairly quickly became docile and unresponsive although that phase lasted for years, so care demands were far different.. My wife stayed home the whole time of her fight. I often wondered and wonder -- today is the 3 month "anniversary" of her death and a tough day -- if I made the right choice. In our case she specifically asked to stay home, so I have that comfort, but I did wonder about more stimulation, friendships, etc. at a facility. We are in a small town and I only had three options. Two would not take her (too care-intensive and not in their model of care) and one was not anywhere I would have put her.

You are wise to be thinking and addressing all your options!

SO wish I could be more helpful!

Peace and strength
