I find it can be difficult to keep dementia residents in an activity room, but if it is only me in charge of the activity, I will let them come and go as they please. I find if I have music or can make the remaining residents laugh, then my wanderers are more likely to check out what is happening. I will also do some spontaneous activities in the hallway, balloon toss, delivering scented flowers or playing a card game like red or black will keep residents interested. Recently, we had a an activity called "Beauty Bar" where we had fifties music playing, we passed out punch and offered quick manicures and massages. Most everyone we brought stayed and had a good time!
