Are there special nursing homes for people who have aggressive dementia?

There are ALs that specialize in dementia and know how to address. A friend's Dad was in one AL that couldn't handle the father and wanted him to add 24/7 on top of the AL services and costs! He visited another and they knew exactly how to handle (he was sexually aggressive) and the new place put a patch on his back and all was well!

Many nursing homes and assisted living facilities have units to care for persons with dementia.
