I so activities in several adult family homes. One home has a deaf resident with dementia. I do not know sign language. I am looking for ideas of activities to do with her.
Maybe you could try a tasting session - make use of other senses - try the biscuit quiz with samples of them - they can bring back great memories for people!
Are you looking for ideas to do one on one or do you want to include her in a group?
Here are some ideas
Use cue cards

Use some techniques that you use with those who have aphasia

Thank you for your suggestion
Pam made me think of other sensory things you could do
